Configure Alarm 1
Alarms 2 and 3 configuration (and Alarms 4 and 5 if option board fitted

Alarm 3 can also be configured as a Wash alarm if A3: Type is set to
Wash – see following frame.
Alarm 1 Type
Select the type of alarm required:
Off
– The alarm is disabled, the alarm LED is off and the relay is de-energized
at all times.
Alarm
– The analyzer is configured using the Assign frame (following) to generate
an alarm in response to a specified high or low pH, Redox (ORP) or
process temperature sensor reading.
Status
– An alarm is generated if either a power failure or a condition that causes
any of the error messages in Table 8.1 (page 62) to be displayed occurs.
Wash
– Alarm 3 is configured to control the wash sequence.
Note.
The Wash alarm type can be assigned only to Alarm 3 and is displayed only when

Select the alarm assignment required:
Sen.A
– The analyzer activates an alarm if the pH or Redox (ORP) value of the
Sen.B
Process fluid measured by the selected sensor exceeds or drops below
the value set in the Alarm 1 Set Point parameter, depending on the type
of Alarm 1 Action selected – see next page.
Temp.A
– The analyzer activates an alarm if the temperature of the process fluid
Temp.B
measured by the selected sensor exceeds or drops below the value set in
the Alarm 1 Set Point parameter, depending on the type of Alarm 1 Action
selected – see next page.
A–B
– The analyzer activates an alarm if the difference between the Sensor A
and Sensor B readings exceeds or drops below the value set in the
Alarm 1 Set Point parameter, depending on the type of Alarm 1 Action
selected – see next page.
Note.
The Sen.B, Temp.B and A–B alarm assignment types are applicable only to dual
