Voltage Current Monitor-EN Specifications

OUTPUT ¹:
Continuous Monitoring:
Local: 3 ½ digit liquid crystal display indicating Peak Current, Average Current, Peak Shaft Voltage * or Power/Alarm Check, selectable with rotary switch
Remote: 4 to 20 mA signal representative of Peak Ground (Earth) Current
4 to 20 mA signal representative of Average Ground (Earth) Current
4 to 20 mA signal representative of Peak Shaft Voltage *
Alarms ²:
Local: LED for minimum and maximum brush current and maximum shaft voltage *
Remote: Open contact on minimum and maximum current, maximum shaft voltage and loss of power supply to the unit * (User selectable latching is optionally available in Non-Explosion-Proof Enclosures Only)
INPUT: Ground (Earth) Current Lead (from shunt in ground (earth) circuit)
Voltage Lead (from shaft-monitoring, voltage sensing brush)

¹ Accuracy: ±1% of maximum rating.
² Minimum Current is 3% (adjustable) of maximum rating, indicating possible loss of brush contact with shaft. Maximum Current is 100% of shunt rating.
Maximum voltage is 0.1, 1 or 10 V (preset at factory, based on information provided by user).
* Voltage-sensing brush required [ie: One brush for voltage readings and one brush for grounding (earthing)].
