Handling endless loop problems
As explained above, an endless loop problem will be declared when the number of consecutive
wash cycles triggered by the DP sensor exceeds the “Loop Limit” defined during setup. When an
endless loop problem is detected, it will be indicated on the screen (LOOPING) and the alarm
output will be activated. In addition, the indication of DP should no longer be taken into account
as a trigger for washing. Subsequent wash cycles will only be triggered by a countdown interval.
The problem will be considered solved when the constant indication of the DP sensor has been
eliminated.

Handling low pressure
When an indication of closed contact is received at the controller's low pressure input, the
symbol will begin to appear flashing on the display. All activities will stop including the
countdown to the next wash cycle. If there is low pressure while a flush sequence is in progress,
when the low pressure condition ends, the flush sequence will start from the beginning instead
of continuing from the stop point.
7.11
Connecting the DP sensor to the filter system
The DP sensor is connected to the filter system by 2 command
tubes, one that comes from the filter inlet (high pressure) will be
connected to the red point, and the one that comes from the outlet
(low pressure will go towards the black point. It is important to
install a small 120 mesh filter (not provided) between the red dot
and the high pressure connection point.
7.12
Low battery
The unit has two levels of low battery indication. The first level is when the battery voltage drops
to the first level, the sign will start to appear on the screen. When the battery voltage
continues to drop and reaches the second level, all outputs will close, the screen will clear
displaying only the low battery icon.
7.13
Manual activation
The wash sequence can be activated manually by using the “MANUAL” key. When activated
manually, the icon will appear on the screen. The same key will be used to manually end the
sequence in progress.
