ROGRAMMING
GROUP 4 contains LM1 and LM2 set limit values for the voltage and amperage scale allowing the user to program
the limits for the following Groups: VOLTS phase-to-neutral, VOLTS phase-to-phase, AMPS A, B, C, and AMPS
neutral.

The EPM3000P has two Relays. These relays are linked through the program to Set Limits LM1 and LM2. The user
can program above or below set limits for every reading. When a measurement exceeds a particular value, the set
limit triggers and alerts the user. Each relay is programmed to a separate delay time (see Chapter 8).

ALL FUNCTIONS HAVE A TWO PART ENTRY
Part 1: The first switch sets the limit to trip either above or below the limit value.
The second switch sets whether Relay 1 will trip when the condition occurs.
The third switch sets whether Relay 2 will trip when the condition occurs.
Part 2: The second part is the Limit Value.
