CT Rating
The maximum current the CTs will read when
outputting 333 mVAC.
If the CTs being used do not output
333mVAC at full scale, they can either
not be used or a calculation must be done
to determine what the current would be at
333mVAC. The maximum voltage the TCU
CT Inputs can read is 353 mVAC.

Full Load Current 1
The average current drawn from pump 1 (or
the station if in Direct Input mode) while
running at full capacity. This setting is used to
determine the thresholds for the undercurrent
and overcurrent alarms. Alarming can be
disabled by setting this to 0.
0 - 100

Full Load Current 2
The average current drawn from pump 2
while running at full capacity. This setting
is used to determine the thresholds for
the undercurrent and overcurrent alarms.
Alarming can be disabled by setting this to 0.

Full Load Current 3
The average current drawn from pump 2
while running at full capacity. This setting
is used to determine the thresholds for
the undercurrent and overcurrent alarms.
Alarming can be disabled by setting this to 0.

Undercurrent Alarm
The percentage of Full Load Current where
an undercurrent alarm is generated. Can be
disabled with 0.
0 - 99%
3%
Overcurrent Alarm
The percentage of Full Load Current where an
overcurrent alarm is generated.

to phase current imbalance before an alarm is
generated. Can be disabled with 0.
