3.O4 Alarms (Probe Mode Only)
Low Detergent Alarm (Flashes the lower line of each digit in the display and beeps in three sets of three beeps.)
• The visual and audible low detergent alarm occurs if the conductivity is below the set point, and the detergent feed
activates, but after a user-defined number of racks (the Low Detergent Alarm Delay), the conductivity has not increased.
• The low detergent alarm will automatically reset if the controller senses an increase in conductivity in the wash tank before
the Detergent Overfeed Stop Alarm occurs.
Detergent Overfeed Stop Alarm (Flashes the lower lines and right 0in display and beeps sets of three beeps continuously.)
• If a low detergent alarm condition continues for twice the user-defined number of racks in the Low Detergent Alarm Delay,
with no increase in conductivity, the visual and audible Detergent Overfeed Stop Alarm will occur and the detergent feed
will be stopped until the alarm is manually cleared.
• When the issue causing the Detergent Overfeed Stop Alarm is resolved (such as installing a new container of detergent or
cleaning the conductivity probe), the alarm can be manually cleared by pressing any of control keys (Next, Scroll or Enter).
