GE EPM 5350 Limits or Relays Programming Procedure, LM1 LED, LM2 LED, Switch, Level, Above/Below

CHAPTER 12: GROUPS 4, 5, AND 6 – SET LIMITS AND RELAYS

12.5: Group 6, Functions 0–5—LM1/LM2 Set Limits and Relay Triggers for Over/Under %THD Conditions

LM1 LED	LM2 LED	SWITCH 1	SWITCH 2	SWITCH 3	LEVEL
		ABOVE/BELOW	RELAY 1	RELAY 2
ON	OFF	Digit Up	Digit Up	Digit Down	012.0
OFF	ON	Digit Down	Digit Down	Digit Up	009.0

Table 12.9: Group 6—Example for Function 0

So, if THD exceeds 12%, LM1 is triggered and Relay 1 is enabled.

If THD falls below 9%, LM2 is triggered and Relay 2 is enabled.

12.6: Limits or Relays Programming Procedure

NOTE: The procedure for programming any limit or relay for each group is identical. The example below signifies the exact procedure for programming a Limit/Relay for GROUPS 4–6.

—Group 4 is used as an example.

NOTE: Press MAX/MIN/LIMITS at any time to cancel before storing the last digit or switch.

FUNCTION

RELAY SWITCHES

Step 1:

a. Enter Group Level of Programming Mode (see Chp. 8).

b. Press MAX/MIN/LIMITS until 4. appears in upper display.

c. Press AMPS to activate the Group.

Step 2:

a. Press MAX/MIN/LIMITS to select desired Function.

!Middle display provides the currently selected value for whether to trip above or below, activate Relay 1 and activate Relay 2.

Left Switch: UP position indicates above tripping value for lower display’s value. DOWN position indicates below tripping.

Middle Switch: UP position sets Relay 1 to trip.

DOWN position doesn’t activate Relay 1 when limit condition exists.

Right Switch: Same as Middle Switch , regarding Relay 2.

b. Press VOLTS to toggle between LM1 and LM2 settings.

!The LM1 or LM2 annunciator indicates the limit being displayed.
