(2)
Unlock door locks and open panel door.
(3)
Disconnect pump cable leads at T1 and T2 and reverse their locations.
(4)
Close and lock the panel door and re-start pump (refer to step b. above) .
(5)
If pumping volume increases, pump is now performing at maximum. If volume is less, repeat steps (1)
through (4) to return leads to their original locations.
d. Turn H-O-A switch and main power switch to OFF. Wait one minute, then open panel door.
e. Turn the TRIP DELAY and RESTART DELAY switches to OFF, then install a temporary jumper to load monitor
terminal board across the normally open (N.O.) contacts. (See figure 2-55).
f. Temporarily close panel door and turn main power switch to ON. Turn H-O-A switch to AUTO and push START
button to start pump motor. Open panel door.
g. With the motor running, turn the TRIP LEVEL adjust until the UNDERLOAD (red) and MOTOR RUNNING
(green) LEDs alternately illuminate. This will set the base running amperage.
h. Connect a DC voltmeter to the load monitor by installing voltmeter plugs into positive and negative jacks. (The
red jack is positive, the black is negative. ) Note the voltage reading.
i.
For purposes of making the final adjustment, consider the voltage reading above as 10096, and adjust the "trip
adjust" to 809% of that reading.
EXAMPLE:
1009% of voltage reading is 8.5 volts
x .80
Final setting is 6.8 volts
j.
While observing the voltmeter, turn the TRIP LEVEL adjust until the voltmeter indicates the voltage calculated
(as in example: 6.8 volts). Remove voltmeter.
NOTE
The 80% setting may be further adjusted to suit unusual installations. If the unit trips when an underload
condition appears to be present, adjust to a lower percentage of the 100% reading. Likewise, if the unit
fails to trip on an underload, adjust for a higher percentage.
k. Temporarily close panel door and turn H-O-A switch to OFF, and main power switch to OFF. Wait 1 minute,
then open panel door and remove jumper from load monitor terminal board.
