The IPM status display is one of the most useful features of the relay‟s display system and should be
viewed as the first step in fault finding. The „Relay Status Page‟ is the default screen on power up and
shows the current status of the IPM Protection Relay.
[ Need IPM Start ]
Load [Pump # 1 ]
I= 0 Amps V= 0 V
Line 1: A one-line status message is displayed and if more than one message is active the
display cycles through all active messages at 1 second intervals.
Line 2: IPM Software version appears here while the UP arrow key held.
Line 3: Shows the Load Type and Number (from the connected RTM unit).
Line 4: Shows the Load Current (3ϕ average) and Load Voltage (average ϕ - ϕ.)
Through the use of the Modbus communications port, PLC‟s and SCADA systems can be configured to
display the same messages that appear on the display. This helps to provide consistent information to
operators.
