5.1 PREVENTIVE MAINTENANCE
The following paragraphs describe the periodic preventive maintenance checks and actions that should
be performed on the BA-200. The Lithium Grease used in the following checks and procedures is "White
Lithium Grease, 30-140, NLGI Grade 2".
5.1.1 MONTHLY CHECKS
At monthly intervals the mechanical portions and the water tight integrity of the BA-200 should be
checked as follows:
- Remove power from the unit at the circuit breaker.
- Remove the knurled nut from the back of the unit and slide off the cover.
- Switch the power on.
- Check the sensor frame beneath the probe for droplets of water or water discoloration.
- Observe that the sensor plunger is reciprocating at 7 RPM or every 8.5 seconds.
- If any of the above conditions are not satisfactory, refer to the corrective maintenance portion of this
manual.
- Turn off AC power.
- Replace cover.
- Return power to the unit as required.
5.1.2 QUARTERLY CHECKS
At 3 month intervals, the unit must be lubricated using a high quality lithium grease as outlined below:
- Remove AC power from the unit at the circuit breaker.
- Remove the knurled nut and cover.
- Use a wooden or non-metallic device to coat the drive wheel with grease. Do not get excess grease
on other components of the unit.
- Replace the cover and knurled nut.
- Restore power to the unit as required.
5.1.3 BIANNUAL CALIBRATION
At six month intervals the BA-200 should be removed from the line and recalibrated. This service is
available from the manufacturer at a nominal charge. The unit may be calibrated on site with a calibration
