Trouble Shooting Tips
Troubleshooting tips are provided here as a beginning point in correcting start-up
issues and clearing out alarm and trip events.
High Temperature Reading/Alarm
The following summarizes some of the possible causes and solutions for heat trac-
ing high temperature alarms.
Cause Possible Solutions
Temperature of product in process line
is above alarm set point or the expected
reading due to events other than heat
tracing - high processing temperatures,
steam-outs, etc. Let process return to normal condition
or adjust alarm set point (if approved by
project engineer) to allow for this process-
ing condition.
High alarm setting programmed or ex-
pected reading did not consider natu-
ral temperature overshoot associated with
the control scheme. Move control set point down to allow for
overshoot or raise the high temperature
alarm set point (if approved by project en-
gineer). It may also be possible to de-
crease the control band on the control cir-
cuit or adjust the type of control from on-
off to proportional.
