6.2 Emergency ShutOFF timer
The emergency ShutOFF timer shuts the pH and/or ORP pumps down if they have operated
continuously for a preset time without the pH and/or ORP values coming back to within the limits.
For example, this condition could occur if the chemical drum is empty, the probe is faulty and
giving an incorrect reading, or if added chemicals were not within detection of the probe. The
ShutOFF feature provides a safeguard against dosing entire Chlorine and/or Acid drums to the
pool.
The Pool Size set-up adjusts the Emergency ShutOFF Timer to the ideal values for that pool size.
For more details or to change the ShutOFF Times, see section 9.6.
6.2.1 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
Chemflo
beeps.
To re-set the ShutOFF timer, press the
key.
No further automatic control will occur for that reading 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…
x
Re-fill the Chlorine or Acid drum if they were empty.
x
Check that the pH / ORP reading is correct. Use a test kit or have the water tested.
x
Consider selecting a larger pool size to allow longer ON time for the Dosing pumps.
