Possible cause/Suggested solution
Overcurrent
The current has exceeded the level set in parameter 5E
Overcurrent
for longer than the time set in parameter 5F
Overcurrent Delay
. Causes can include a momentary overload
condition.
Related parameters: 5E, 5F, 6E
Overpower
The motor has experienced a sharp rise in power. Causes can
include a momentary overload condition which has exceeded the
adjustable delay time.
Related parameters: 5M, 5N, 6I
Overvoltage
There has been a voltage surge on the mains. Causes can
include problems with a transformer tap regulator or off-loading
of a large transformer load.
Related parameters: 5I, 5J, 6G
Parameter out of
range
This trip is not adjustable.
•
A parameter value is outside the valid range. The keypad will

•
An error occurred loading data from the EEPROM to RAM
when the keypad powered up.
