RCRS is an encapsulated microprocessor-based, intelligent, self-monitoring control unit for automatic function testing of the regulating combustion gas damper BRSS. Can be connected to 1 damper and max. 2 detectors. RCRS acts as an independent control unit and performs automatic function tests every 48 hours after power up/resetting. Function tests can also be initiated by an external switch. The detector input features an electronic short-circuit fuse. The damper enters alarm mode in the event of a short circuit or a break in the detector loop. Includes an input for controlling the damper with a 0-10 V signal from an external sensor. RCRS can be used to limit the min. and max. damper positions during normal operation.
It also includes an input for forced control of the damper to the open or closed position. Forced control always has higher priority than min./max. limits and incoming control signals. Forced opening has higher priority than forced closing if both signals are present. Output signal 0-10 V for damper position indication.
Normally supplied fitted on combustion gas damper RABCR/RABRR; see separate product sheet.
