CHAPTER 9: PROGRAMMING GROUP 0 - GLOBAL METER SETUPGROUP 0, FUNCTIONS 4–5—TIME DELAY FOR RELAYS 1 & 2 (OPTION – NL)
EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL 9–65
9.7 Group 0, Functions 4–5—Time Delay for Relays 1 & 2 (Option – NL)
GROUP 0, FUNCTIONS 4–5 sets the time delay for Relays 1 and 2 between 0
and 255 seconds. This allows conditions (example below) to exist for a user-
specified time period before the relay or alarm activates. If a time greater than 255
seconds is entered, the meter defaults to the maximum value of 255 seconds.
Example: If Relay 1 is set for 300 amps and the amps increase to 301, the Relay trips only
after a programmed delay period. If the meter then measures 299 Amps, the Relay returns
to its original position, after the programmed delay.
Relay 1: Located in 04.0 & 04.1.
Relay 2: Located in 05.0 & 05.1.
(Procedures for both relays are the same).
To change Time Delays:
Note
Press MAX/MIN/LIMITS at any time, to cancel before storing the last digit or Switch.
