GE EPM 5200, EPM 5300, EPM 5350 There are 3 Switches to SET with Limits, Digit Up Digit Down 0120

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

THERE ARE 3 SWITCHES TO SET WITH LIMITS:

1)Switch 1: Sets the limit to trip either above or below the Limit Value.

2)Switch 2: Sets whether Relay 1 will trip when the condition occurs.

3)Switch 3: Sets whether Relay 2 will trip when the condition occurs.

After the switches are set, the limit value should be programmed (see table in section 12.4).

LM1	LM2	SWITCH 1	SWITCH 2	SWITCH 3	VALUE
LED	LED	ABOVE/BELOW	RELAY 1	RELAY 2
ON	OFF	Digit Up-trigger above value	Digit Up-enabled	Digit Up-enabled	0-9999
		Digit Down-trigger below	Digit Down-	Digit Down-	0-9999
		value	disabled	disabled
OFF	ON	Digit Up-trigger above value	Digit Up-enabled	Digit Up-enabled	0-9999
		Digit Down-trigger below	Digit Down-	Digit Down-	0-9999
		value	disabled	disabled

Table 12.5: Group 5: Functions 0–7

LM1 LM2 SWITCH 1 SWITCH 2 SWITCH 3 VALUE

ON	OFF	Digit Up	Digit Up	Digit Down	0120
OFF	ON	Digit Down	Digit Down	Digit Up	0090

Table 12.6: Group 5: Example for Function 0

Thus, if Kilowatts exceed 120 W, LM1 is triggered and Relay 1 is tripped.

If the Kilowatts fall below 90 W, LM2 is triggered and Relay 2 is tripped.

SPECIAL CASES

FREQUENCY: FUNCTION 4 contains a permanent decimal after the second digit. The highest and lowest level limits that can be programmed are 99.99 and 00.00, respectively.

POWER FACTOR: FUNCTIONS 3 and 6 contain a permanent decimal after the first digit. The highest and lowest limits that can be programmed are 1.000 and 0.000, respectively.
