Symptom Solution
Water (condensate) appears within the
enclosure.
If the control has a Type 3R/IP43 enclosure, inspect the grommet in the
field-installed cable gland or conduit fitting, and replace the grommet if it is
defective.
If the control has a Type 4/IP67 enclosure, inspect the case-to-cover
O-ring provided on the flow switch. Ensure that the O-ring is in place and
undamaged. Ensure the control uses a correct cable gland or conduit
fitting for Type 4/IP67 applications.
Fluid from the tank leaks into the enclosure
due to a rod seal failure.
Replace the flow switch.
Switch does not activate due to debris in
switch mechanism.
Clear any debris from within the switch mechanism. Test the operation of
the switch several times for proper operation.
Control switch action is reversed. Ensure connections follow wiring diagrams.
Control does not switch. Check the electrical connections.
Switch fails to return to the no-flow position. The switch may be set lower than the factory setting. Increase the setting.
On vertical pipes, ensure that the direction of flow is up. The arrow on the
switch enclosure must point in the direction of the flow.
Control does not switch on flow increase. Check for a cracked or broken paddle. Replace the paddle, if necessary.
