Functional description The DUNGS motorised butterfly valve is an automatic actuator driven by auxiliary energy. The electromechanical actuator drive determines the position of the valve. Partial load and full load setting of the valve are specified by adjusting the switching cams of the actuator drive. The acting time is specified by selecting the actuator drive. If the operating voltage (auxiliary energy) is interrupted, the actuator remains in its current position. Installation - When installing, refer to the flow direction ( arrow) on the housing. - Keep to the specified installation position. - Do not use actuator as lever when screwing unit in. Use suitable tools on housing. Perform leakage and functional tests after mounting. Direct contact between hardening masonry, concrete walls, floors and motorised butterfly valve is not permitted. Set pressure reference value on gas pressure regulator. Only perform load reduction via motorised butterfly valve. k v values of valves with preferred throat diameter Preferred diameter [mm] DMK 507 DMK 510 Valve position ø 11 ø 13 ø 15 ø 17 ø 19 ø 1 ø 3 ø 4 ø 5 ø 6 ø 8 ø 3 ø 36 ø 40 ø 46 90 3.98 6.34 9.59 14.14 0 0.3 0.8 0.3 0.36 90 7.0 10.0 15.3 0.6 0 0.3 0.36 0.40 0.45 DMK 51 90 6.58 10.00 13.81 17.88.59 9.9 0 0.3 0.36 0.40 0.45 0.59 0.53 DMK 515 90 1.45 7.63 34.13 48.7 0 0.51 0.55 0.60 0.68 DMK 50 90 40.63 56.07 76.39 116.1 0 0.68 0.77 0.85 0.89 Equipment selection The following values must be known for the DMK rating: 1. Maximum volumetric flow V max.. Pressure loss p at maximum volumetric flow. 3. Minimum volumetric flow V min. 4. Pressure loss p at minimum volumetric flow The throat diameter can be determined optionally using the k v value or the diagrams 1, and 3. Check whether the required minimum volumetric flow is attained in valve position 0. If the calculated or read-off value is below the specified minimum volumetric flow, the valve can be used. At smaller volumetric flows, the pressure loss of upstream equipment is reduced and the available p of the valve increases.

Functional description The DUNGS motorised butterfly valve is an automatic actuator driven by auxiliary energy. The electromechanical actuator drive determines the butterfly valve position. Valve partial load and full load adjustment is defined by adjusting the related actuator drive switching cams. The actuating time depends on the actuator drive selected. If the operating voltage (auxiliary energy) is interrupted, the actuator remains in its current position. Installation - When installing, refer to the flow direction ( arrow) on the housing. - Keep to the specified installation position. Avoid direct contact between the motorised butterfly valve and dried masonry, concrete walls or floors. Only set the nominal pressure on the pressure regulator. Any output-related restriction should only be performed using the motorised butterfly valve. Check for leaks and function after installation. k V values of valves with preferred throat diameters Preferred diameters [mm] DMK 5040 DMK 5050 DMK 5065 DMK 5080 DMK 5100 DMK 515 Valve position 90 0 90 0 90 0 90 0 90 0 90 0 40 10. 0.85 50 131.4 1.35 65 55.5.59 80 357.7 3.8 100 565.75 4.0 15 104.5 5.48 Selecting the device You must know the following values to select the DMK variant: 1. Maximum volume flow V max. Pressure loss p at maximum volume flow 3. Minimum volume flow V min 4. Differential pressure in the closed valve position (= p e ) You can either determine the throat diameter by calculation using the k V value or using diagrams 1,, 3 and 4. Check whether the required minimum volume flow is reached when the valve is positioned at 0. If the calculated or measured value is below the required minimum volume flow, the valve can be used. If the volume flows are small, the pressure loss of upstream devices will fall. This increases the p available to the valve. To obtain an optimum control response, always choose the valve with the largest pressure loss ( p > 10 mbar). K V value for DMK motorised butterfly valve The DMK motorised butterfly valve is limited by the following parameters: operating pressure pmax = 500 mbar (50 kpa) differential pressure pmax = 50 mbar (5 kpa) When the valve is used in subcritical flow states, the following applies: V N [m 3 /h] volume flow, standard state p [bar] pressure drop across DMK p [bar] absolute pressure downstream of DMK ρ n [kg/m 3 ] standard gas density T 1 [K] absolute gas temperature upstream of DMK Vn = 514 k V p p ρ n T 1 3 6

Control device for system leakage test DSLC px Vx 8.1 Visual display of the entire program sequence Display of the leaky valve Display remains visible if there is loss of voltage IP 4 Technical description Together with one or two gas pressure switches, the DSLC control device built according to EN 1643 for system leakage tests checks the burner gas shut-off valves for leakage. A synchronous gear motor with control cams controls the DSLC program sequence via microswitches. Application The DSLC is suitable for automatic leakage tests between two solenoid valves in gas-consuming devices. The testing system can be used alone for leakage tests or combined with all types of automatic burner control systems. It can be used in gas burner control systems for heating and industrial purposes, gas combustion motors etc., with or without pipes for venting into the open air.

Functional description and program sequence shown with 1 pressure switch The section from valve seat V1 to valve seat V is called test section. The DSLC performs a test before every burner start-up, i.e. when heat is requested by the controller or after the unit is switched off due to loss of mains voltage, gas shortage etc. The test consists of two phases: 1. Test of the valve (V1) on the gas inlet side. Test of the valve (V) on the burner side When heat is required, the controller circuit is closed, and the DSLC receives voltage and starts the test cycle (approx. 60 s). At the beginning of the first test phase (figure 1a), valve V is opened for max. 3 s. The pressure in the test section must drop to atmospheric pressure, i.e., the pressure switch P p must switch back after the pressure is relieved. If it is not possible to evacuate the test section, the pressure is relieved again after 60 s. During the subsequent test time (figure 1b) the pressure built up in the test section must not exceed the switch point of the pressure switch P p. However, if this happens due to leakage in solenoid valve V1, the DSLC takes the fault position and prevents the burner from being started. The red fault display lights up. There is voltage at terminal 5 of the device for teleindication of the fault. The DSLC opens valve V1 for max. 3 s before the second test phase (figure a). Thus, the test section is under gas pressure, and the second test phase begins. During the subsequent test time (figure b) the pressure in the test section must not drop below the switch point of the pressure switch P p. However, if the pressure falls due to leakage in valve V, the pressure switch P p reports this and the DSLC is locked in the fault position. All parts lying in the test section, such as pressure switches, pipes, screw joints etc., are simultaneously tested for leakage. Only after the second test phase, too, shows that all parts are properly sealed, the DSLC through-connects the controller circuit (voltage at terminal 15) and enables the program sequence for starting up the burner. 1a 1b Test section Test section a b Test section Test section 3 8

Venting in the firing chamber According to EN1643 venting may be carried out in the firing chamber if the volume released [m 3 ] per test cycle does not exceed 0.05 % of the nominal volume flow [m 3 /h]. Example: For a nominal volume flow of 100 m 3 /h, the permissible volume is 0.05 m 3 = 50 dm 3 Schematic diagrams 1. Valve test with auxiliary valves V3, LGV.

The valves used must meet the requirements of EN Nominal diameter For main actuators > DN 65, auxiliary valves should be used. Avoiding leakage The most common reason for leaky actuators is dirt accumulation. Therefore, the gas filter preceding the gas control section must be sufficiently large. Special attention must be paid to loss of pressure in the filter, i.e. the filter must be checked and cleaned at regular intervals. 4 8

Test pressure switch One or two pressure switches can be used for monitoring the pressure in the test section: A change-over contact is required if a common pressure switch (P p ) is used for test phases 1 and. The switch point of the pressure switch must be set to half of the gas flow pressure. If set properly, two pressure switches detect even small amounts of leaked gas. The amounts of leaked gas can be individually set to the required value for: test phase 1 (safety solenoid valve) with pressure switch P1 and test phase (burner solenoid valve) with pressure switch P. The pressure switches used must meet the requirements of EN 1854! Limit value The DSLC must prevent ignition and the opening of the actuators at a limit value < 0.1 % of the burner consumption (with regard to the burner capacity), or < 50 dm 3 /h (the higher value must be taken into account). We recommend that a max. limit value of 00 dm 3 /h should not be exceeded. Gas leakage rate The gas leakage rate can be recalculated using the equations, and the switch points of the test switches can be changed if necessary.

Functional description Functions according to the force comparison principle between the force of: - the adjustable setpoint spring - the defined counterspring - the differential pressure at the working diaphragm and - the force due to weight of the moving parts The counterspring acts against the adjustable spring and the weight due to force of the moving parts. Depending on the pretension of the adjustable spring and the installation position, the force of the counterspring is compensated. Overcompensation leads to positive regulator output pressures, partial compensation leads to negative regulator output pressures. Instructions Gas-conveying lines, pulse and connection lines must be made of steel and at least PN 1, DN 6. The lines must be resistant to thermal, chemical and mechanical loads. The lines must be durable and deformation- and crackproof. Do not route condensate from lines into the pressure regulator. Do not apply burning gas or combustion gas air mixtures to the installation chamber of the adjustable spring.

The output pressure is set at the reference value adjustment device (14). The servopressure regulator controls the pressure regulator (5) via nozzle (7). The slow opening function is enabled by a damped pressure increase. The opening time of MBC-10 cannot be set. With MBC-10, the opening behaviour can be adjusted at high operating pressure values. Start flow adjustment The adjustment screw (15) for the start flow restrictor (10) is closed (factory setting). The start flow can be set by opening the restrictor up to approx. 80 % of the main flow. Main flow adjustment The adjustment screw (13) for the main flow restrictor (9) is completely open (factory setting). The servopressure regulator keeps the output pressure upstream of the main flow restrictor constant. The burner pressure is determined when the output pressure and the main flow restrictor (9) are adjusted.

Functional Description Gas flow 1. If valves V1 and V are closed, chamber a is subjected to inlet pressure.. The min. pressure switch (option) is connected to chamber a via a boring. If the inlet pressure drops below the desired value set on the pressure switch, the switch opens in the direction of the gas burner control system. 3. After they are enabled by the gas burner control system, valves V1 and V open. Gas flow is released through chambers a and b. Functional description of the combined valve-regulator unit Valves V1 and V can be controlled electrically and separately. Each valve preloads its own compression spring when the plunger opens. When the two valves are open, a pressure pulse runs below the working diaphragm. The size of the pressure pulse changes as a factor of the variable restrictor position D. The outlet pressure p Br acts against the setting spring force via the servo diaphragm until a force equilibrium is attained. The opposite side of the servo diaphragm is subjected to ambient pressure p amb. Changes in the equilibrium of forces lead to a change in flow cross-section. The pressure under the working diaphragm re-adjusts itself. The regulator unit adapts the free valve cross-section to the new flow requirement.

Functional Description Gas flow 1. If the V1 and V valves are closed, chamber a is under inlet pressure.. The min. pressure switch (option) is connected to chamber a via a borehole. If the inlet pressure exceeds the reference value set in the pressure switch, the switch switches through to the automatic burner control. 3. The V1 and V valves open after they are enabled by the automatic burner control. Gas flow through the chambers a and b is enabled. Functional description of the valveregulator combination Valves V1 and V can be controlled electrically and independent of each other. Each valve pretensions its own pressure spring when the plunger opens. If both valves are open, a pressure pulse is sent under the working diaphragm M. The intensity of this pressure pulse changes depending on the adjustable restrictor point D. The comparison diaphragms S 1 for burner pressure p Br and S for blower pressure p L are connected with each other via a rod. The ratio V can be set by shifting the bearing point. Zero point correction N acts on this rod mechanism via the air diaphragm S. Ambient pressure p amb or firing chamber pressure p F must be applied to the area between the comparison diaphragms. The firing chamber pressure reduces the burner pressure at a ratio of V > 1. Changes in the equilibrium of forces result in a change in the flow crosssection. The pressure under the working diaphragm is re-adjusted. The regulator unit adapts the free valve cross-section depending on the new flow requirement. Closing function If the supply voltage of the solenoid coils of V1 and V valves is interrupted, the pressure springs close the valves in <1s.

Functional Description Gas flow 1. If the valves V1 and V are closed, chamber a is subjected to inlet pressure up to the double seat of the valve V1.. The min. pressure switch (option) is connected to chamber a via a bore hole. If the inlet pressure exceeds the desired value set on the pressure switch, the pressure switch connects through to the gas burner control system. 3. The valves V1 and V open after they are enabled by the gas burner control system. Gas flow through chambers a, b and c is enabled. Functional description of the combined valve-regulator unit at valve V1 A regulator (pressure regulator unit) with admission pressure compensation is integrated in valve V1. The plunger V1 is not connected to the valve disc unit. When the plunger opens, it preloads the compression spring and releases the regulator unit. When the plunger closes, the closing pressure is applied directly to the valve discs of the regulator unit. Valves V1 and V are driven together electrically. When valve V3 is in the closed position, it closes off the pressure chamber under the working diaphragm M so that this chamber is not affected by the inlet pressure p1 in chamber a. The plunger of valve V1 controls the valve V3. The pressure under the working diaphragm M depends on a variable flow cross-section D. The comparison diaphragms for burner pressure p Br and blower pressure p L are connected with a bar. The ratio V can be set by shifting the bearing point. The zero point compensation N acts on this bar. Ambient pressure p amb or firing chamber pressure p F must be applied to the opposite side of the comparison diaphragms. The firing chamber overpressure reduces the burner pressure when the ratio V > 1. If there are any changes in the equilibrium of forces, the flow cross-section D after the valve V4 is changed. The pressure under the working diaphragm is re-adjusted, and the valve disc unit V1 changes the free cross-section. Functional description valve V The plunger of the valve V is connected to the valve disc unit. When the plunger opens, it preloads the compression spring. The valve V opens completely without any delay. The valve V4 is actuated by the valve V. When the valve V4 is in the closed position, it closes off the area under the working Schematic diagram MBC-...-VEF V1 Main valve 1 V Main valve V3 Control valve 3 V4 Control valve 4 M D V N Pressure taps, gas train diagram MBC-...-VEF p1 Working diaphragm Restrictor Ratio setting Zero point compensation diaphragm M so that this area is not affected by the burner pressure.

Functional description of gas flow 1. When the valves V1 and V are closed, chamber A is under inlet pressure.. A hole D in the filter housing connects min. pressure switch with chamber A. If the inlet pressure applied to the pressure switch exceeds the incoming reference value, it switches through to the automatic burner control. 3. After release by the automatic burner control, valves V1 and V open. The gas flows through chambers A, B and C of the GasMultiBloc. Operating method of valve-regulator combination on valve V1 A regulator, compensating for residual pressure is integrated in valve V1 (pressure regulating part). Armature 7 is not connected with valve plate unit 3. When it opens, armature 8 pretensions compression spring (V1) 5 and releases the valve plate unit. When the valve closes, the armature acts directly on the valve plate unit. The output pressure upstream of valve V is defined by pretensioning regulating spring 8 (tension spring) via setting screw 17. The output pressure acts via opening E on the working diaphragm 1 of the regulator part. In regulated state, setting spring inlet pressure and pressure of working diaphragm are in force equilibrium. The compensating diaphragm ensures the fast closing function of valve V1 and a high regulating quality. Operating method of valve V The armature 14 of valve V is connected to valve plate unit 1. When it opens, armature 14 pretensions the closing spring 13. The max. valve opening can be set by limiting the armature stroke by means of the main volume restrictor 18. Min. opening (residual stroke) of valve (0.5 to 1.0 mm) The main volume restrictor 18 is set by rotating the adjusting plate or the hydraulic brake 0. The fast and/or slow opening characteristic is influenced by setting fast stroke 19 at the hydraulic brake under the cover. Closing function When the supply voltage to the solenoid coils of valves V1 and V is interrupted, they are closed within < 1 s by the compression springs.

Pressure limiter for multiple actuators ÜB A NB A 5.07 1 6 Technical description The pressure limiters ÜB A and NB A are compact pressure switches as per EN 1854 for DUNGS multiple actuators. The pressure switches are suitable for switching a circuit on, off or over on changes in actual pressure value relative to the set reference value. The reference valve (switching point) can be set easily and quickly by means of a setting wheel provided with a scale without the use of a pressure gauge. Application Pressure switches for DUNGS multiple actuators GasMultiBloc and DMV double solenoid valve. Various mounting options directly on housing or by means of an adapter. Standard mounting on valve housing on the inlet side via threaded flange. Suitable for gases of families 1,,3 and other neutral gaseous media. Approvals EC type test approval as per EC Gas Appliance Directive: ÜB A CE-0085 AO 30 NB A CE-0085 AO 30 EC type test approval as per EC Pressure Equipment Directive: ÜB A NB A CE0036 CE0036 Approvals in other important gasconsuming countries. Special designs for the North American market with U L, FM and CSA registrations.

Functional Description Single-acting pressure limiters in the superpressure range. The pressure limiters work without external energy supply. Pressure limiters ÜB A / NB A The switching mechanism reacts to superpressure. The system is locked if the set reference value is exceeded or undershot. After the fault has been remedied, the system can be put into operation only manually by actuating the unlocking device on the pressure limiter. The switching state Locked is indicated by a neon glow lamp. ÜB A: Switches on and locks if the set pressure value is exceeded. NB A: Switches on and locks if the pressure is lower than the set pressure value. ÜB A switching function As pressure rises NO closes, 1 NC opens Glow lamp ON, locked. COM 3 1 NO NC NB A switching function As pressure falls NO opens, 1 NC closes Glow lamp ON, locked.

Pressure build-up: The internal motor pump increases the gas pressure in the test section by about 35mbar compared with the pressure arising on the inlet side at valve V1. During the test period (pump period) the integrated differential pressure switch monitors the test section for leaks. When the test pressure is reached, the motor pump switches off (end of test period), and the yellow LED flashes until the contact is released. The release time (max. 6s) is dependent on test volume (max. 0l) and inlet pressure (max. 360mbar). If the test section is leak-tight, the contact is released to the automatic burner control after 6s and the yellow LED comes on. If the test section is leaky or if the pressure rise by +35 mbar is not reached during the test period (max. 6 s), the VDK 00 A S0 switches to fault. The red signal lamp lights as long as the contact is released by the regulator or thermostat (heat request). An automatic restart is performed on short-term voltage failure during the test or in burner mode. Operation: Valve V1 and valve V are open, the internal valve of VDK 00 A S0 is closed. 3 6

Made in Germany ø 4.6 for self-pressing screws M5 Typ: VDK 00 A S0 Störung Betrieb Dérangement Fonctionnement Blocco Funzionamento Lockout Run Functional description The VDK 00 A S0 operates according to the pressure build-up principle. The program module starts to function when heat is requested. Test is performed depending on the burner functional procedure: - Test prior to burner start or - Test during pre-purge time or - Test after burner shut-down Function principle The VDK 00 S0 performs a self-test during a switching sequence. Startup 1. Check test section for leaks after assembly.. Start test by using temperature regulator and/or restart or by pressing the reset button on VDK 00 A S0. 3.If the test section is tight Depending on the length of the test section and the residual pressure applied, the pumping time can be up to 6 s. The release for the automatic burner control system is granted at the latest after approx. 6s - the yellow signal light illuminates continuously. If the test section is leaky The test pressure is not reached. The motor pump switches off, the red fault lamp lights up. Switch-through to the automatic burner control does not take place. Functional check By opening a screw plug p (p a ) during the test period (pumping time), leakage can be simulated and a function check can take place. Setting The VDK 00 A S0 is preset at the factory. Setting the VDK 00 A S0 is possible on site. Setting is performed at the externally accessible setting screw. Apply varnish to the setting screw after startup. Keep strictly to the instructions. Assembly The VDK 00 A S0 must be connected to the DUNGS single valves (can be mounted on the right or the left) by means of two steel pipes (ø 1 mm). If an exhaust gas valve is installed in the boiler, it must be open at the beginning of the test. In order to prevent functioning and tightness problems, we recommend to use solenoid valves according to EN 161 Class A. The connection lines between VDK 00 A S0 and the valves must withstand mechanical, chemical and thermal loads. 4 6

Electrical connection VPS 508 S03 The VPS 508 S03 is connected in series between the temperature regulator and the control box via a 7-pin plug connector. The pin assignment of the connector between burner and boiler is specified in DIN 4791. For contact assignment, refer to wiring diagram.if the heat generator is wired to DIN 4791,no boiler or burner rewiring is required for electrical connection. Connect the burner connector to the floating connector of the VPS 508 S03. Connect the VPS 508 S03 connector to the floating connector on the heat generator. If there is a fault signal at S3 (burner fault), the regulator chain is bridged via an additional relay in VPS 508 S03 on the burner side. At the same time, the operating voltage of VPS 508 S03 is interrupted. After eliminating the burner fault, the valve testing system can be started again. Only connect the incoming fault signal from the igniter of the burner control to port S3. If this is not observed, damage or injury may result. Therefore, please keep to the instructions.

Startup 1. Check test section for leaks after assembly.. Start test by using temperature regulator and/or restart or by pressing the reset button of VPS 508. 3. If the test section is tight Depending on the length of the test section and the residual pressure applied, the pumping time is between 3 s and 34 s. The release for the automatic burner control is then given after approx. 10 s at the earliest (at small test volumes and small input pressures) and after approx. 34 s at the latest (at large test volumes and large input pressures) - the yellow signal lamp lights up. If the test section is leaky The test pressure is not attained. The motor pump switches off, the red fault lamp lights up. Switch-through to the automatic burner control does not take place. Functional check By opening a screw plug in test nipple p (p a ) during test period (pumping time), leakage can be simulated and a function check can take place. Setting The VPS 508 must not be adjusted on site. Assembly Directly flange the VPS 508 laterally to the DUNGS multiple actuators (mounting is possible on left-hand or right-hand side) using two 10.5 x.5 O rings and four M4 x 16 self-tapping screws. If an exhaust gas valve is installed in the boiler, it must be open at the beginning of the test. In order to prevent functional and leakage problems, we recommend the use of solenoid valves as per EN 161 Class A and Class B. Insufficiently shielded frequency converters could cause faults in the VPS due to network disturbances. Make provisions for sufficient electrical shielding. 9 1

Further settings possible via VisionBox + parameter change: 1. Freely selectable number of operating cycles up to 6.5 million (standard 100,000). Signal output with freely selectable number of operating cycles of V, LGV or release 3. Signal output while the test is running or while voltage is applied 4. Signal after successful switch-off Program sequence can be selected Three different program sequences can be selected via DIP switches: 1. Valve test before burner start. Valve test after burner switch-off 3. Test sequence with optimised valve operating cycles after burner switchoff without additional switching cycles. In this case, only one valve will be tested at a time after successful switch-off, --> lower power consumption and increased valve life. Test times can be set DIP switches can be used to select predefined test times of V1 and V, enabling optimal setting in case of different test volumes, inlet pressures and leakage rates. Alternatively, individual test times, even different times for V1 and V, can be set via VisionBox. Filling and venting attempts Depending on the test volume, different combinations can be selected using DIP switches. Signalling for V1 and V Red/green LEDs signal various information on the program and release states or error codes. TWI interface Plug-in connection for DUNGS VisionBox.

According to EN1643, 1 filling or 1 emptying attempt for max. 3 s into the burner chamber is admissible (DUNGS as-delivered configuration). At filling and emptying times of 1 s of the gas main valves, max. 3 attempts are admissible. If the number of venting attempts is higher, venting must be into a safe area (LGV vent valve). 5 10

Installation examples The functional principle must be selected in accordance with the local regulations Prevent soiling by using appropriate gas filters Use of pilot valves recommended Please note: Switch positions ➊ ➋ ➌ ➍ ➊ According to EN1643, 1 filling or 1 emptying attempt for max. 3 s into the burner chamber is admissible (DUNGS as-delivered configuration). At filling and emptying times of 1 s of the gas main valves, max. 3 attempts are admissible. ➋ When filling or emptying attempts are carried out via pilot valves, the situation described in ➊, shows that the specifications of EN1643 are also met with 10 filling or emptying attempts if pilot valves are used that can reach at most only 1/10 of the maximum gas flow of the main valves. ➌ If the valve check is carried after a regular shutdown, the system setup must ensure that locking the system prevents a valve check during a fault situation. This can only be achieved by safe interruption of the power supply to the VPM when a fault occurs. ➍ If this switch position is used, parameter setting should be checked via the VisionBox. 1a - - - Direct valve check via LGV, venting through roof Valve check system component: VPM-VC, Pp, LGV VPM VC GW 1 V1 P p V LGV (NO) V GW1 V1 V1 in FA OK LGV REMOTE RESET NO NC Pp1 FAULT COM FAULT MULTI COM MULTI NO NC Pp1 Pp DIP-mode: A: 1100 1001 ➌ 0011 ➌ ➍ B: xxxx C: 1100 0110 0011 ➊ ➍ Parameter: --- TR L1 N N 1b - - - Direct valve check via LGV, venting into the burner chamber Valve check system component: VPM-VC, Pp, LGV VPM VC GW 1 V1 P p V LGV (NO) GW1 V1 in FA OK REMOTE RESET NO NC Pp1 FAULT COM FAULT MULTI COM MULTI NO NC Pp1 Pp DIP-mode: A: 1100 1001 ➌ 0011 ➌ ➍ B: xxxx C: 1100 ➋ 0110 0011 ➊ ➍ Parameter: --- V V1 LGV TR L1 N N Notes regarding 1a, 1b, : If a valve closed when not powered is replaced instead of a LGV (open when not powered), it must be connected to output V (terminal 8). 6 10

5a - - - VPM VC GW 1 V1 Valve check via pilot valves, venting to V via LGV type (normally closed) Valve check system component: VPM-VC, Pp, LGV Type (NC) The LGV type is required for opening the gas flow behind V (to the burner chamber or atmosphere), allowing it to be emptied when V is deliberately (during the test) open. The pressure behind V must be able to escape, since otherwise V, as response to "No gas pressure", allows gas to pass in the reverse direction during the test time, if there is still pressure behind V. This allows the pressure to drop in the monitored interspace if V is leaking. During release (automatic burner control is working), the LGV type is closed.
