1.
Isolate the float by disconnecting one or both of the
float leads from the float terminals.
2.
Place one ohmmeter lead on one of the float wires, and
the other ohmmeter lead on the other float wire.
3.
Place the ohmmeter dial to read ohms and place on
the R X 1 scale. With the float in the “off” position, the
scale should read infinity (high resistance). Replace
the float if you do not get this reading. With the float
in the ON position, the scale should read nearly zero
(very low resistance). Replace the float 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 the fuse. With power OFF, pull the
fuse out of the fuse block. With the ohmmeter on the R X 1
scale, measure resistance. A reading of infinity indicates a
blown fuse and must be replaced. Replace fuse with same
type, voltage and amp rating.
Indicator Light
If defective, replace all indicator lights with same type.
Alarm Horn
Moving the test/nor-
mal/silence switch to
the test position or
activating the alarm
float 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 float should turn on the alarm light.
If the light does not activate, replace light with same type.
Circuit Breaker (optional)
Check each pole of the circuit breaker for proper resistance
reading using the following procedure.
WARNING: Disconnect incoming power to panel.
1.
Isolate the circuit breaker by disconnecting either 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 infinity (very
high resistance). With the breaker in the ON position,
the reading should be nearly zero ohms (very low resis-
tance). If the readings are not as stated, replace the
circuit breaker with one of the same ratings.
NOTE: Readings may vary slightly depending on the
accuracy of the measuring device.
Float Controls
Check the floats during their entire range of operation.
Clean, adjust, or replace damaged floats.
Checking the float resistance
- The float resistance can
be measured to determine if the float is operating correctly
or is defective. Use the following procedure to measure
the float resistance.
WARNING: Disconnect incoming power to panel.
