Soft fill time-out
The Soft fill function in the PID control-
ler has timed out. The wanted process
value was not achieved within time.
Reason might be a pipe burst.

Process supervi-
sion fault (PID1)
PID controller: Feedback value outside
of supervision limits (and the delay if
set).
Check settings.

Process supervi-
sion fault (PID2)
PID controller: Feedback value outside
of supervision limits (and the delay if
set).
Check settings.

Input pressure
supervision
Input pressure supervision signal has
gone below the alarm limit.
Check the process.
Check the parameters
Check the input pressure sen-
sor and connections.
1409
Input pressure supervision signal has
gone below the fault limit.

Temperature
fault 1
At least one of the selected tempera-
ture input signals has reached the
alarm limit.
Find the cause of temperature
raise.
Check the temperature sensor
and connections.
Check that the temperature
input is hardwired if no sensor
is connected.
See option board manual for
further information.
1316
At least one of the selected tempera-
ture input signals has reached the fault
limit.
112
1317
Temperature
fault 2
At least one of the selected tempera-
ture input signals has reached the fault
limit.
1318
At least one of the selected tempera-
ture input signals has reached the fault
limit.
