CHAPTER 9: PROGRAMMING GROUP 0 - GLOBAL METER SETUPGROUP 0, FUNCTIONS 4–5—TIME DELAY FOR RELAYS 1 & 2 (OPTION – NL)

9.7Group 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).
