1. Technical description.
1.1. General description.
PC2 (AWZ 518) time module is used for control of AC supply state of object alarm systems (monitoring
transmitters, alarm centrals, DC power supply unit etc.). The module makes it possible to pass information about decay
of AC supply with the set delay time of T (3s/63s/17m37s/4h45m, +/-2%) and information about recovery of AC supply.
Recovery of AC voltage (transient) during counting of T delay time triggers counting reset (i.e. stop and return to the
normal state). The module has an AC1 input that shall be connected to a secondary wiring terminal of a transformer
supplying the device (the module shall be supplied by 12V/DC, i.e. the device to which the controlled transformer
terminal is connected). PC2 has two OC outputs (OC1, OC2) and a LED (L1) indicating the state of the device. Two Z1
and Z2 jumpers are used for configuration of the signalling delay time of AC supply decay.
