Memco Interceptor Installation Guide Ref. No. 180 850GB Version 4 Installation to Lift Controller ++ Fit to top corner of the Lift Door, ‘ ++ Mark holes & use 3mm Drill bit & use fixing screws provided [Fig1] or if a fixing plate [optional] has been supplied fit as Fig 2. Note: Use the ‘Fan Disc Washer’ under the screw head, this provides the earthing link between Interceptor & the lift door. ++ Remove power to the lift controller while wiring the Interceptor. ++ Connect the 0V [Orange Wire] to an 0V supply terminal on the controller. ++ Connect the ‘Power’ [Red Wire] to a positive supply +9 - 36VDC [10mA]. ++ Connect the ‘Trigger’ [Blue Wire] to the appropriate ‘Light Barrier’ or ‘Safety Edge’ input on the lift controller. Fig 1 Fixing Screws Fig 2 Fixing Plate Note: The transistor output is rated at +30VDC max with a 250mA maximum switching current, if unsure of the voltage & current use a 280/281 PSU. ++ Re-apply the power to the lift controller. Warning! The Interceptor output and supply connections are designed for low voltage DC use only. DO NOT apply voltages of more than 36VDC to any connection. Prevent the output current from rising above 250mA as irreversible damage may be caused. Wiring directly to the Lift Controller Fig3 - Shows the ‘Light Barrier Input’ to a ‘Door Controller’, requires 0V to open the doors Fig4 - Shows the ‘Light Barrier Input’ to ‘Door Controller’, requires +12VDC to open the doors Fig5 - Shows ‘Light Barrier’ ‘Door Open Circuit’ need to be broken to open the lift doors. This solution requires a separate relay with a DC coil voltage rated as the power supply Installation using a 280/281 PSU TX Cable 0V - orange +12V - red Dispo. - blue Power Supply Door ReOpen Circuit Fig 6 ++ Remove power to the lift controller & wire correct ‘Input Supply Voltage’ to the 280/281 ++ Connect the ‘Door Operator Contacts’ ++ Connect the 0V [Orange Wire] to the 0V terminal as in Fig6 ++ Connect the ‘Power’ [Red Wire] to the +12VDC terminal as in Fig6 ++ Connect the ‘Output’ [Blue Wire] to the Trigger terminal as in Fig6 ++ Re-apply the power to the Lift Controller Fig 7 shows the ‘Safety Edge Input’ to a ‘Lift Controller’ that requires the ‘Door Open Circuit’ to be broken to open the doors. This solution uses the 280/281 PSU. Fig 7 Troubleshooting Guide Possible Cause Red LED not illuminated after Interceptor Interceptor is detecting a passenger is installed 0V or supply not connected Sensitivity turned up too high Doors re-open whilst closing Interceptor is not picking up passenger Solution Stand clear of the doors Check wiring Turn the sensitivity control towards ‘Min’ Shaft wall is in field of view of the Interceptor Lower the position of the Interceptor Door is not properly connected to earth Ensure that the ‘Fan Disc Washers’ have been fitted Sensitivity set too low Turn the sensitivity control towards ‘Max’ Avire Ltd Memco is a brand of Avire Clyde House, Reform Road Maidenhead Berkshire SL6 8BY, UK T: 01628 540100 F: 01628 621 947 E: [email protected] W: www.memco-global.com W: www.avire-global.com IT IG V04 (GB) Symptom
