1 Chapter: Actuators Page: of Sheet No.: Ci ISB Solenoid Actuator Ci ISB Solenoid actuator Item numbers covered by his datasheet 00 Ci ISB Solenoid only 0 Ci ISB Solenoid & Manual General The Solenoid actuator is part of the Control Inert (Ci) series. The Ci ISB has superior performance with regards to shock, vibration and reliability, as it utilizes neodymium magnets, hence reducing the number of moving parts to a minimum. There are two versions; a standard solenoid and a solenoid with built-in manual activator. The Ci ISB has a built-in EOL resistor allowing monitoring of the complete activation circuit, this resistor can be changed to make it compatible with most control panels. Two actuators can be used in a parallel with control panels rated at Amp, if the panel is capable of supplying minimum Amp for minimum 0 msec. When replacing an old IS the connection cable has to be replaced.

Before installing the Ci ISB it must be checked that it is reset (plunger app. mm submerged), failure to do so may cause unintended discharge of system. The M connector is a male, screw type, with pins. A corresponding cable (supplied with the actuator) must be used. : +Ve Brown : +Ve White : -Ve Black : -Ve Blue Operating Electrical.

3 Chapter: Actuators Page: of Sheet No.: Ci ISB Solenoid Actuator Maintenance After activation the Ci ISB must be reset manually, by below procedures. Solenoid only actuator:. Unplug the electrical connection. Unscrew the Ci ISB from the Ci-IV valve.. Connect the Ci ISB to FE tool 0. (Make sure that the reset tool is screwed all the way back before connecting). Operate the reset tool until a low click is heard from the Ci ISB and then turn the knob approx. one more turn. The actuator is reset when the knob becomes significantly harder to turn (do not exceed 0Nm). Turn back the reset tool. Remove the Ci ISB from the tool.. Check that the plunger is submerged into the body approximately mm.. Refit the Ci ISB to the discharge valve as described under installation. Solenoid & Manual actuator: As the Solenoid only with these deviations (also applies when it has been activated electrically). Turn back the manual activation knob (counter clockwise) (pin and seal must be removed). Use reset tool as described in the Solenoid only.. Gently turn the manual knob clockwise until increased torque is noticed.. Turn the manual knob back between and 0, until the locking pin can be inserted fully.. Secure the locking pin with fine sealing wire and seal through the Ø holes in the knob and pin. Routine testing To verify correct function of the electrical actuation system the solenoid may be activated annually. To verify sufficient force of the Ci ISB a scale may be used to measure the force. A force of 0N is required to start pushing back the piston.

4 Chapter: Actuators Page: of Sheet No.: Ci ISB Solenoid Actuator Section drawings Ci ISB in normal (non activated) position The armature is held in the closed position by a magnetic field created by the permanent magnet in the actuator body. Ci ISB in fully activated position (electrical actuation) When an electrical current passes through the coil windings in the correct direction, the magnetic field is weakened, releasing the armature. The armature, rod and piston are driven forward by the Belleville springs, pushing the front of the rod out of the actuator. This actuates the Ci IV valve. Ci ISB in fully activated position (manual actuation) When the manual knob is turned clockwise, the knob screw pushes on the piston. This lifts the armature away from its seat, weakening the magnetic field. Once the magnetic field has been weakened, the armature, rod and piston are driven forward by the Belleville springs, pushing the front of the rod out of the actuator. This actuates the Ci IV valve.

6 Chapter: Actuators Page: of Sheet No.: Ci ISB Solenoid Actuator Electrical interfaces Sigma XT control panel connection: If only one Ci ISB is connected to a Sigma XT, the end-of-line resistance must be changed to approximately 00 Ω. Otherwise the Sigma XT will indicate an open circuit fault. The recommended solution is to replace the end-of-line (EOL) resistor with a 00 Ω resistor. Alternatively an external 00 Ω resistor can be fitted in parallel with the Ci ISB. Changing the end-of-line resistor This operation can only be performed by Fire Eater (during production). An EOL resistance of less than k should never be used (due to heat issues). If monitoring voltage exceeds V, the minimum EOL resistance is k. Remove the black cover plate secured by two in-hex screws. Locate the EOL resistor, remove it and install the desired resistor. When replacing the cover, be careful to align the screws properly and see that all seals are in place. Screws are tightened Nm. Test the electrical actuation circuit by activating the Ci ISB electrically. Special cables This operation can only be performed by Fire Eater (during production) The M connector may be replaced with a standard cable gland (Mx.) if required, as there is a screw terminal behind the cover plate. Remove the black cover plate secured by two in-hex screws. Locate the terminals that connect to the M connector and unscrew the wires. Unscrew the M connector and install the cable gland. Route the cable trough the cable gland and connect the bare wires in the appropriate terminals. Tighten the cable gland nut to seal and secure the cable When replacing the cover, be careful to align the screws properly and see that all seals are in place. Screws are tightened Nm. Test for short circuit (resistance must exceed MΩ) between housing and wires. Test the electrical actuation circuit by activating the Ci ISB electrically. Grounding This operation can only be performed by Fire Eater (during production) It is not recommend to ground the actuator to the control panel as it may create a ground loop trough the cylinders/pipe system. If it is absolutely necessary to ground the actuator body through the cable, this is possible by using the M grounding screw under the black cover (opposite the PCB). The M connector must be replaced with a standard cable gland to allow use of this. As a lot of circumstances are to be considered when grounding the actuator it is recommended that the installer is aware of his responsibility with regards to system integrity before doing so.
