4 4 Technical User Guide 1 Product Description DA 74BC is a 24V winch motor with a wall fitting and an arm which is used to adjust wall inlets, ceiling inlets or emergency opening of windows and doors in houses. DA 74BC can be mounted for either ON/OFF or stepless regulation and is controlled by a house computer. The winch motor can be operated manually by disconnecting power, activating the push button for the manual release and turning the wall fitting arm. Before activating the manual release, you must retain the wall fitting arm. DA 74BC can be set to ON/OFF, stepless, ON/OFF reverse or stepless reverse using the jumper on the PCB. DA 74BC is controlled by 24V DC, ensuring safe emergency opening in case of a power failure or other failure. DA 74BC is easy to clean thanks to its compact design Figure 1: DA 74BC Position Article no.

6 6 Technical User Guide 3 Mounting Guide Check that all parts are present and undamaged before mounting the DA 74BC winch motor. 3.1 Mounting DA 74BC (C) Mount the wall fitting (A) on the wall. Screws and rawlplugs (B) are included. They may, however, be inadequate, depending on the wall material. (B) (A) (D) Figure 2: Wall fitting (E) Turn the pull arm (C) so that the wide groove (D) in the plastic shaft fits in with the slot (E) in the toothed rim of the gear unit. Figure 3: Toothed rim Push DA 74BC into the wall fitting. Mount the retaining disc (F) and locking screw (G). (F) (G) Figure 4: DA 74BC

7 Technical User Guide Mounting the Cover Mount the cover by turning the six quarterturn screws, Figure 5 (A) Checking Manual Operation (A) (B) Check the manual release when the cover has been mounted. Press the push button, (B) and check by turning the pull arm. Hold on to the arm before activating the release. Figure 5: Manual operation Checking Adjustment Mount the mechanical connection between the winch motor and the inlet, window, door, and the like to be adjusted. Check that: 1) The inlet, window, door, and the like can open/close completely. If not, readjust the mechanical connection and check again Installation of adapter for swivel shutter Using the DA 74 adapter for swivel shutter, the DA 74BC winch motor can be mounted on an axle diameter from mm. The DA 74 adapter is ordered separately. Mount the axle in the shackle and tighten the two nuts. Torque should be between Nm. Figure 6: DA 74 adapter for swivel shutter Before the axle and winch motor are connected, both must be in the same position (open/open or closed/closed).

8 CALIBRATE 8 Technical User Guide 4 Installation Guide 4.1 Electrical Connection Qualified personnel in accordance with the applicable national and international standard EN and any other EU standards that are applicable in Europe must perform installation, service and fault finding of al electrical equipment. The installation of a supply isolator is required for each motor and power supply, so maintenance of electrical equipment can be carried out in a dead environment. Supply isolator is not supplied by SKOV A/S Cable Routing All cables must be mounted in M25 glands, protection class minimum IP65. Cables are to be secured in the usual way outside the cabinet. Close holes which are not used with IP65 safety plugs.

STEPLESS REVERSE Control voltage +24V/0V => Open. 0V/24V => Close. Feedback signal > 0.5V => O.C. turns ON. Feedback signal > 9.2V (85 degree opening) => relay turns ON Testing the Electrical Installation 1) See jumper setting, section ) Activate the house computer to transmit a closing signal. Check closed state and adjust the mechanical connection, if necessary. 3) Activate the house computer to transmit an opening signal. Check closed state and adjust the mechanical connection, if necessary Calibrating the End Stop It is not necessary to calibrate using the CALIBRATE button on the PCB, unless the PCB, solenoid or gear has been replaced. Calibration must be carried out before connecting the mechanical connection, otherwise the mechanical connection must be fine adjusted again.

12 12 Technical User Guide 5 Maintenance Guide DA 74BC does not require any special maintenance, however, we recommend that the system be serviced once a year. 5.1 Cleaning Figure 13: Cleaning Annual Inspection Clean the product with water and a brush without using: high-pressure cleaner solvents corrosive/caustic agents 1) Open the cabinet cover to check the inside functions; check also that no fluid can penetrate into the cabinet as this may damage gears and other components. Pay attention to the shaft sealing and the sealing of cable lead-throughs. 2) Activate the manual release and check that the swivel shutter moves unobstructedly in its entire working range. 5.2 Dismantling for Recycling/Disposal SKOV A/S' products which are suited for recycling are marked with a pictogram showing a refuse bin that is crossed over. See picture. Customers can dispose of SKOV A/S products at local collecting points/recycling stations according to local directions. The recycling station will then send the products to an approved plant for recycling and reuse LED Indication (A) OK = slow flashing (1 flash/sec.) Calibration = constantly on Fault = fast flashing (10 flashes/sec.) Figure 14: LED

13 Technical User Guide Troubleshooting/Remedy Even though the DA 74BC has been designed to work without supervision, malfunctioning may occur. Check the following to remedy any faults. Symptom Cause Solution The winch motor does not run, the LED does not flash at all. No power supply or is the power supply below 12V? Check supply voltage. Check fuses. Check assembly according to the connection and circuit diagram. The LED (A) flashes quickly 10 times/second. Has the motor plug been mounted? Has calibration been forgotten? The motor stutters. Has the solenoid been mounted? Mount the plug. Press the CALIBRATE button; the LED must be constantly on while the winch motor opens and closes. Remove any object which may have been trapped. Mount the solenoid. Inlet, window or door not completely open/closed. No feedback signal from the house computer. Adjust the mechanical connection. When using ON/OFF 278M and 378M, connect Q1 to C17/B17 on the main module. Table 2: Troubleshooting/remedy
