Check the ﬂ oats during their entire range of operation. Clean,

adjust, or replace damaged ﬂ oats.

Checking the ﬂ oat resistance - The ﬂ oat resistance can be

measured to determine if the ﬂ oat is operating correctly or is

defective. Use the following procedure to measure the float

resistance. Warning: Disconnect all incoming power to panel.

Failure to do so could result in serious or fatal electrical shock.

1. Isolate the ﬂ oat by disconnecting one or both of the ﬂ oat leads

from the ﬂ oat terminals.

2. Place one ohmmeter lead on one of the ﬂ oat wires, and the

other ohmmeter lead on the other ﬂ oat wire.

3. Place the ohmmeter dial to read ohms and place on the R X

1 scale. With the ﬂ oat in the “off” position, the scale should

read inﬁ nity (high resistance). Replace the ﬂ oat if you do not

get this reading. With the ﬂ oat in the ON position, the scale

should read nearly zero (very low resistance). Replace the

ﬂ oat if you do not get this reading.

NOTE: Readings may vary depending on the length of wire

and accuracy of the measuring device.

Fuses

Check the continuity of each fuse. With power OFF, pull the fuses

out of the fuse blocks. With the ohmmeter on the R X 1 scale,

measure resistance. A reading of inﬁ nity indicates a blown fuse

and must be replaced. Replace fuse with same type, voltage and

amp rating.

Magnetic Contactor Coil

Warning: Disconnect all incoming power to panel. Failure to do

so could result in serious or fatal electrical shock. Check the coil

by disconnecting one of the coil leads. Measure the coil resistance

by setting the ohmmeter on the R X 1 scale. A defective coil will

read zero or inﬁ nity, indicating a short or opened coil respectively.

Replace defective contactor with same type.

Control/Alarm Circuit

Board Power

If the green power

status indicators are not

illuminated:

1. Check to see if the

fuses on the circuit board are blown.

2. Check to see if the incoming control/alarm power is present

at TB1-1 and TB1-2.

If voltage is present and fuse is not blown, please call factory for

assistance.

Circuit Breaker (optional)

Check each pole of the circuit breaker for proper resistance reading

using the following procedure:

Warning: Disconnect all incoming power to control panel.

Failure to do so could result in serious or fatal electrical shock.

1. Isolate the circuit breaker by disconnecting either the line side

or load side wires.

2. Place the ohmmeter leads across the corresponding line and

load terminals of each pole.

3. With the ohmmeter on the R X 1 scale and the breaker in

the OFF position, the reading should be inﬁ nity (very high

resistance). With the breaker in the ON position, the reading

should be nearly zero ohms (very low resistance). If the

readings are not as stated, replace the circuit breaker with

one of the same ratings.

Alarm Horn

Moving the test/normal/silence switch to the test position or

activating the alarm ﬂ oat should turn on the alarm horn. If the horn

does not sound, replace horn with same type.

Alarm Light

Moving the test/normal/silence switch to the test position or

activating the alarm ﬂ oat should turn on the alarm light. If the light

does not activate, replace with bulb of same type.
