Set Limits and

Relays

The EPM 5300P -NL offers a comprehensive limit and set point functionality. The user can program above or below limits for every reading, including %THD. When a voltage or current measurement exceeds a particular value, the set limit is triggered and alerts the user. Each limit can trigger two internal Form C dry contact relays for alarm or secondary protection.

The EPM 5300P offers two set limit points available for each measured function: LM1 and

LM2. Each limit can be set at any desired level. Note: The EPM 5200P does not have limit setting capability.
