The system shall include a multi-function microprocessor control providing adjustable hold open time (1 30 sec.), LED indications for actual position unknow
29、n, system status, open obstruction shutdown, activation signal, safety mat/sensor signal, Stop-and-Hold signal, and mode selector switches providing a means for easy field selection of the following functions: push-to-operate, latch assist and stack pressure. Control shall be capable of receiving ac
30、tivation signals from any device with normally open dry contact output. 1. With push-to-operate function enabled, the control shall provide a means of initiating a self-start activation circuit by slightly pushing the door open at any point in the door swing. 2. Latch Assist shall provide a two seco
31、nd impulse in the close direction to overcome restrictions with locking devices of pressure differentials, allowing the unit to operate in standard time delay mode, and permitting the door to close from the full open position after the hold time is satisfied.
