6.4 Alarms
The
Chemflo
has an alarm function for the ORP and pH readings. The alarm trips if the ORP
reading is above or below the Set Point by at least 30 mV. It also trips if the pH reading is above or
below the Set Point by at least 0.3 pH. This alarm is useful, as it can provide forewarning of a
potential system problem.
The
Chemflo
continues to operate as normal while the Alarm is displayed, as it will continue to try
to rectify the condition.
6.4.1 Procedure in event of Alarm function being tripped
When the alarm function has been tripped, the message “
Alarm
” flashes next to the ORP and/or
pH reading (whichever has tripped the alarm).
Automatic control will continue even while the alarm is activated, as the
Chemflo
will
attempt to correct the alarm condition.
The condition that caused the alarm function to trip must be rectified to avoid it being tripped again.
This may involve one or more of the following…
x
Check that the pH / ORP reading is correct. Use a test kit or have the water tested.
x
Consider selecting a different pool size to allow long dosing times.
x
The pH and/or ORP levels in the pool may have changed too rapidly for the dosing pumps to
keep up. If this was due to a singular event (eg. top up pool with fresh water), then the alarm
may be ignored. If this was due to normal operation and none of the above suggestions have
worked, contact your dealer.
