6.2.3 Procedure in event of ShutOFF timer being tripped
When the ShutOFF timer has been tripped, the word ‘
sOFF
’ is displayed as the status for the
relevant reading and the
easyCHEM 770
beeps.
To re-set the ShutOFF timer, press the
key.
No further automatic control will occur for that parameter until the
key is pressed.
The condition that caused the ShutOFF timer to trip must be rectified to avoid it being tripped
again. This may involve one or more of the following…
•
Re-fill the Chlorine or Acid drum if they were empty.
•
Check and re-calibrate the ORP and/or pH sensors to ensure the reading is actually correct.
•
Extend the ON time if the pump rate is not high enough to keep up with chemical demand for
the current ON time.
6.2.4 Disabling the Emergency ShutOFF Timer
Extreme caution should be exercised when disabling the ShutOFF timer, as this could allow an
entire drum of Chlorine and/or Acid to be dosed into the pool in the event of a malfunction.
Overdosing Acid can cause serious pool, equipment and health hazards.
To disable the ShutOFF timer, set the ShutOFF time to 0 minutes for ORP and/or pH.
