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 rat-
ing.
Indicator Lights
If defective, replace all indicator pilot lights with same type.
Magnetic Contactor
Contacts
- Check the contacts for severely burnt or welded con-
tacts. The contactor arm should move freely.
Coil
- Measure 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 infinity, indicating a short or
opened coil respectively. Replace defective contactor with same
type.
NOTE:
Readings may vary depending on accuracy of the mea-
suring device.
Motor Protective Switch
Test by inserting a paper clip or other small device into the test
hole and push to the left. The relay should trip.
Alarm Horn
Moving the alarm test/normal/silence switch to the test position or
activating the alarm float should turn on the alarm horn. If the horn
does not sound replace with horn of same type.
Alarm Light
Moving the alarm 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 with bulb of same type.
Float Controls
Check the floats during their entire range of operation. Clean, ad-
just, or replace floats.
Checking the float resistance
- The float resistance can be mea-
sured to determine if the float is operating correctly or is defective.
Use the following procedure to measure the float resistance:
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.
