Measurement alarm codes
Measurement alarms occur when TOC or conductivity levels in the process water are more than the
set limits. Refer to Table 19.
The digital outputs that identify a TOC alarm or conductivity alarm change their state when a
measurement alarm is present.
Refer to Configure the digital output alarms on page 31. The three
analog outputs continue to represent the last measured value when a measurement alarm is present.
