Fig. 4-24 Alarm: If the actual value of a temperature 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 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 setpoint
Switching on cold application groups
Connecting cold or heated temperature channels to hose receptacles
can occur during operation without triggering undertemperature or
overtemperature 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.
