LED’s (INDICATORS) FOR DOSING
OFF
Dosing not active
AUTO
Dosing with automatic control
DOS
Dosing active
If not
'OFF
' and not
'AUTO'
then manual dosing is selected and if no dosing takes place, the dosing is deselected in
the set-up. It may also be off because of too long dosing time if this function is selected but in that case there will
also be an alarm.
If the pH value is outside its limits, there is an ’alarm’ on the chlorine regulation channels if chlorine dosing is active.
The chlorine dosing is stopped until the pH value is within its limits again. This is indicated by flashing AUTO
LED’s on the chlorine channels and alarm text ’PHF’.
LED’s (INDICATORS) FOR ALARM

Insufficient water flow through the flow cell
ALARM
High or low alarm, dosing alarm or flow alarm on the displaying channel

Note. If the

row until the
'ACTIVE'
LED is cleared. Leaving set up mode automatically returns the unit to normal operation.
