3. Auxiliary CT size
Set the CT size for each channel. Enter the value for each
channel separately, or enter one value and click set all
channels. Auxiliary #1 (register 115) to auxiliary #4 (register
118) define the auxiliary or "mains" CT size (typically 200 A).
Type the appropriate numeric value for each auxiliary CT
installed in the panel. CT size must be 1–32,767. Set this
value for each panel on the E3x.
4. Auxiliary breaker size
Set the breaker size for each channel. This value is used
for alarm calculations. Enter the value for each channel
separately, or enter one value and click set all channels.
Auxiliary #1 (register 161) to auxiliary #4 (register 164)
define the auxiliary or "mains" breaker size (typically 225
A). Type the appropriate numeric value for each auxiliary
breaker in the panel. For unused breakers, set the value
to zero to disable alarms for those channels. Set this value
for each panel on the E3x [i.e., 225 (decimal) = 225 A; range
0–32,767].
5. Branch breaker size
Set the size of each branch circuit breaker. The default for
each circuit is 20 amps. The breaker size box and the set all
channels button can be used to set all circuits to the same
value, or each circuit can be set separately to the necessary
value. Channel #1 (register 119) to channel #42 (register 160)
define the channel or "branch" breaker size (typically 20 A).
Type the appropriate numeric value for each channel breaker
in the panel. For unused breakers, set the value to zero to
disable alarms for those channels.
6. Current alarms
The instantaneous current alarm setup parameters define
the maximum (high alarm) and minimum (low alarm) limits
for all branch and main circuits monitored by the ASPMETER.
Instantaneous current alarms are ON only if the alarm
conditions are met. These alarms are reset automatically
(alarm is turned OFF or cleared when circuit current is within
the normal range).
