15.
Use a 5/32" hex key to install the screw in the clamp. Do not overtighten.
16.
Hold the clamp only to lift the sensor.
If the clamp does not slip, it is tight enough.
4.5.2 Troubleshoot BLIS
If the water level in the intake area does not fall while the BLIS is in operation, do the
steps below.
1.
Make sure that the sensor has power supplied and is in communication with the
software.
2.
Make sure the pump has time to operate. The flow rate is approximately 1–1.5 ml per
100 pump cycles (1 ml/min.
3.
Check again for blockage at the intake.
4.
Flush the intake with clean water.
5.
Listen for the pump to click.
a.
If it clicks but water does not flow, contact the manufacturer to send the sensor
for service.
b.
If it does not click, but communicates, contact the manufacturer to send the
sensor for service.
4.6 Maintain bulkhead connector
C A U T I O N
Do not use WD-40
®
or petroleum-based lubricants on bulkhead connectors. It will cause damage
to the rubber.
Damaged connectors can cause a loss of data and additional costs for service.
Damaged connectors can cause damage to the sensor and make it unserviceable.
Examine, clean, and lubricate bulkhead connectors at regular intervals. Connectors that
are not lubricated increase the damage to the rubber that seals the connector contacts.
The incorrect lubricant will cause the bulkhead connector to fail.
1.
Apply isopropyl alcohol (IPA) as a spray or with a nylon brush or lint-free swab or
wipes to clean the contacts.
2.
Flush with additional IPA.
3.
Shake the socket ends and wipe the pins of the connectors to remove the IPA.
4.
Blow air into the sockets and on the pins to make sure they are dry.
5.
Use a flashlight and a magnifying glass to look for:
Cracks, scratches, or other damage on the
rubber pins or in the sockets.
Any corrosion.
