Culligan Mark 100 - Board Diagnostics; Diagnostic Test Mode

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.
