CONTROLS CONTROLS UR SERIES VOLTAGE CONTROL RELAY UL listed CSA recognized AC or DC Voltage Control Manual or Automatic Operation Adjustable Threshold 5 to 50% Hysteresis Range LED Relay Status Indicator 1. AC/DC voltage control without latching: 2 The output relay is energized when the voltage (AC peak voltage) S1 hysteresis exceeds the selected threshold. It de-energizes when the voltage Automatic Threshold falls below the hysteresis setting (5 to 50%) or when supply breaks. Unlatching The hysteresis is controlled by a potentiometer and its selection does R not change the chosen threshold. 2. AC/DC voltage control with latching: The output relay is energized when the voltage reaches the selected S1 threshold and stays latched in this position. The contact between ter- minal B1 and M (or 8 or 9) should be opened or the input power of S2 the device interrupted to reset.

The output relay is energized when the supply Threshold (effective for AC) exceeds the selected threshold. It de-energizes hysteresis when the controlled supply falls below (5 to 20% Hysteresis) of the supply voltage or when the input power breaks. Hysteresis R is controlled by a potentiometer and its selection does not change the chosen threshold. Pulses or drops of 100ms or 0 t less are ignored.
