Page header

Alarm A1 Action
Set the required alarm action from the following table:

The set point band is defined as the actual value of the set point plus or minus
the hysteresis value. The hysteresis value is fixed at 0.1% of set point. Alarm
action occurs if the input value is above or below the set point band. If the input
moves within the set point band the last alarm action is maintained.

Alarm 1 Set Point
The alarm set point can be set to any value within the oxygen range.
[0.00% to 25.00%]

Alarm A2 Action
Set the required alarm action from the above table.
If the alarm action is set to 

General Alarm

, the relay is de-energized and

the associated front panel l.e.d. is illuminated when one or more of the following
conditions is true: thermocouple open circuit; cell warming up; calibration fail,
cell stability check, power failure.

Alarm A2 Set Point
The alarm set point can be set to any value within the oxygen range of 0.3%
to 25.0%.

Note. This frame is not displayed if the 

Alarm 2 Action

 parameter has

been set to 

General Alarm

.

Retransmission Type
The retransmission output is assigned to the oxygen range.
Select the retransmission output current range required (4 to 20mA, 0 to 20mA
or 0 to 10mA).

Logarithmic or Linear Output
The retransmission can be assigned to give a logarithmic or linear output.
Select the output required:

YES

Logarithmic

NO

Linear
