Variable Description Range
# Number of pumps that were 1-6
Pumps entered by the factory (Total
number, number of jockey pumps,
number of standby pumps), see
section 4.2.1.
CT Size of the current transformer in 40, 150, 400
amps, this must be correct for
proper amp and power
measurement.
G Gain for CT calibration (printed Hex values
on the label on the CT), this must 0-F
be correct for proper amp and
power measurement.
O Offset for CT calibration (printed Hex values
on the label on the CT), this must 0-F
be correct for proper amp and
power measurement.
HP1-6 Horsepower for each pump that 0-999.9
was entered by the factory, see
section 4.2.2.
Table 43: Info Screens Variables
Note: There are redundant setup screens for horse-
power and number of pumps. The values entered
here are used to set default values only. The actual
parameters used for operation are shown in section
4.2 and may be different than the values shown here.
5.6 Troubleshooting
Problem Solution
Service Mode LED Set the node switches on the controller to 0 and 0 and cycle power. Set the node switches
(blank screen) back to 1 and 1 and cycle power again.
Pump won’t start Check that the Start/Stop LED is on. Check that the pump status LEDs are blinking to
indicate that they are ready. Press the HELP key from the status screens to check the alarm
screen for any conditions that may prevent the pumps from running. If the RESET/
SILENCE LED is flashing, a manual reset of the system is required.
Pumps won’t stage on/off Check the Staging screen to see what the staging method is and what the next staging values
are. See section 3.4.4. Check the timers screen to be sure that the pump minimum run timer
is expired prior to destaging. See section 3.4.5.
No Flow Shutdown will Check the Timers screen to be sure that the NFSD minimum run time has expired. Only
not occur one pump must be running and the system pressure must be greater than the NFSD restart
pressure in order for NFSD to occur. See section 4.5.6.
Inaccurate amps, voltage Check that the calibration values printed on the label on the current transformer correspond
or power readings to the values shown in the Info screens. See section 5.5.
