Solving endless loops:
As explained above, endless looping problem will be declared when the number of consecutive flushing
cycles triggered by the DP sensor exceeds the "Looping limit" defined during configuration. The fact that
endless looping problem was detected will be indicated on the display and will cause the activation of the
Alarm output, additionally, the DP indication will no longer be considered as a trigger for flushing. The
following flushing cycles will be triggered by the interval count down only.
Low pressure:
When a closed contact indication is received at the low pressure input of the controller, the symbol
will start to appear blinking at the display. All activities will stop including the countdown to the next flushing
cycle. If the low pressure happened while a flushing sequence was in progress, when the low pressure
condition terminates the flushing sequence will start from the beginning rather than continue from the stop
point.
Manual activation:
A flushing sequence can be manually activated by the "MANUAL" key. When manually activated the icon
will appear on the display. The same key will be used for manually terminating a sequence in progress.
Adding and removing of plug-in units:
The number of connections on the Filtron may be altered with plug-in units. Before the configuration is
altered, the power must be removed from the unit.
The addition and removal of the plug-in units happens by sliding the bottom dark grey cover downwards.
Ensure that the plug-in units are all in the left-hand connectors, so when adding units, work from left to
right.
Slide the plug-in unit carefully part way into the connector until the plastic bracket at the bottom fits into
the hole and then slide the unit fully home.
Removal happens in the reverse order.
