Temperature Parameters (contd.)
Alarm
Refer to Fig. 4‐29: If the actual value of a temperature channel is less by the
undertemperature Warning
than the theoretical value that it should
have at least reached after time X, an undertemperature warning is issued.
If the actual value of a temperature channel is less by the undertemperature
Fault
than the theoretical value that it should have at least reached after
time Y, an undertemperature fault is issued.
The same applies accordingly to the cooling phase.
This has the advantage that
Changing the setpoint
Switching on cold application groups
Connecting cold or heated temperature channels to hose receptacles
can occur during operation without triggering undertemperature or
overtemperature fault/shutdown, which would cause interruptions in
production.
NOTE: This feature requires the temperature controller P/N 729450, which is
included in all IPC software versions higher than 1.00.000.
