• Determine if Absolute Process Alarm
is required for channel 2. If not,
access the [AL``2] parameter and
set the value to disable the process
alarm, choosing [`nonE] or
[``dEU]. Refer to programming
guide.
• If Process Alarm for channel 2 is
required, confirm that the [AL`P2]
parameter is set to the proper value
for the application.

ture limiting device.
• The Offset parameter can affect the
alarm point. Confirm that the
[OFSt2] parameter is set properly.
• System may require service.
