Installation Instructions:
1. Unit operates from 12-24 volts AC or DC. Voltage source should be connected to the terminals marked [AC].
When using DC power, polarity does not have to be observed.
2. Use “-- ”, “NC” and “NO” to operate desired devices (magnetic lock, door strike, etc.). During normal operation
positive power is connected to “NC” and transfers to “NO” when timing cycle is initiated.
3. Adjust desirable time. By turning timing potentiometer clockwise you increase the duration of the output.
4. Connect trigger voltage source to both terminals marked [TRG].
Note: Surge suppressors can be used to eliminate RMI that is generated when the electrical coil is powered down.
We recommend to use a diode in parallel with every DC coil magnet (Banded end of diode connected to positive
terminal of coil or magnet).
