Important Safety Information

HIGH VOLTAGE WARNING!

– Turn off power at the

main service panel before installing.

Programmable,

Three-Phase

Voltage Monitor

Phase Unbalance Protection

• Voltage Unbalance: 2-20%, adjustable

Over/Under Voltage

• Under Voltage: 2-25%, adjustable

• Over Voltage: 2-25%, adjustable

Phase Loss Protection

• Phase Loss Condition: Equals 25% of nominal for any given phase; system will

shut down and a fault will be recorded if this should occur.

Delay on Break Timer

• Control Voltage: 18-240 VAC

• Time Delay: 15 seconds to 10 minutes

Fault Interrogation Delay

• Time Delay: 0 – 15 seconds, adjustable

• Provides a delay between fault detection and system shutdown—helps to eliminate

nuisance trips and unnecessary shutdowns.

Voltage Read Calibration:

Hold both down to calibrate line voltage. Fault and setup LEDs will ﬂash.

Usethe and buttonstoadjust.Press SETUP to exit calibration.

Press to enter Setup Mode and select user parameters. Setup LED

illuminates when in Setup Mode.

Press to read faults. Hold for 5 seconds to clear faults and reset memory.

Fault light will blink when fault has been added to memory.

Press and hold to reset system due to system error – this will not reset

the parameters.

To turn backlight on, press any button.
