Using the switches, move to the mA output to be changed
and use
to select it.
Figure 103. Set mA Levels for Warning
Use the switches to decrement or increment the value until
the desired value appears. Use
to select the value and move
to the next setting. Repeat for each setting to be changed.
The default values and available output ranges for Inhibit,
Warning, Overrange, Beam Blocked, and Low Signal are shown
in the following table. See Section
5Warnings/Faults for more
information.

After all changes have been made, use the switches to
move to the ‘ü’ and use
on the front panel to accept and save
the settings. If ü’ is not selected, none of the changes will be
saved.

Calibration Interval
Calibration Interval allows a desired interval for sensor
calibration to be set for sensors attached to the transmitter. The
transmitter will generate a warning when the interval is reached.
Figure 106. Calibration Interval Menu
Calibration Interval will not appear when an IR personality board
is attached and the mA sensor type is set as ‘Other mA Sensor’.
The default calibration values for the “Calibration Required”
diagnostic vary based on sensor type. This value can be repro-
grammed in accordance with site requirements to ensure the
highest level of safety. Correct operation of each sensor should

centration before commissioning.
Although the calibration Interval can be set to any value be-
tween 0 and 360 days, Honeywell Analytics recommends that the
interval for electrochemical and catalytic sensors be set to 180
