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-

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.
