Board Diagnostic
To enter the board test mode, flip all of the dip switches to the ON position. All the segments of the board will light until
either a key is depressed, an option is changed or a CAM micro switch changes position. Pressing one of the keys,
closing a micro switch or turning OFF a dip switch will cause a different segment to light as outlined in Table 5.
A balanced signal should be applied to the Aqua-Sensor
®
pin connector. This can be done with a clean Aqua-Sensor
probe and a fully regenerated bed or with the Aqua-Sensor Tester, PN 01-0079-99.
An unbalanced signal will cause the drive motor to run continuously. A balanced signal will cause the motor to stop.
This test can be used to check the integrity of the Aqua-Sensor probe. If the probe is connected to the board and
the drive motor runs continuously, the probe should be cleaned and checked.
