ALARM
The integrated pH controller has two ALARM LEDs, which are illuminated whenever a pH
value outside the range 6.5 – 8.5 is detected. When the controller detects an active alarm,
control output to the dosing pump is turned-off.
The integrated ORP controller has two alarm LEDs that are activated automatically when the
readings are outside the prefixed range (650 - 850 mV). For security reasons, the controller
turns-off the control output when the upper limit (850 mV) is exceeded.
