Control relay to monitor permanent safety rails on roller shutter doors
On the application of the supply voltage and after detection of a diode or a 8k2 resistor connected to the input, the output relay energizes and the green LED (safety rail o.k.) is illuminated.
When the control relay detects an open circuit, the output relay drops out immediately and the yellow LED (open circuit) is illuminated.
When the control relay detects a short circuit, the relay drops out immediately and the red LED (failure) is illuminated.
When the output relay drops out a red LED flashes to indicate a circuit fault.
supply voltage variation nominal voltage -15%... +10%
frequency range - 48 - 63 Hz
duty cycle - 100%
