If the temperature diagnosis is not activated by the time the "START" signal is deactivated (i.e. if the ACTUAL tem-
perature does not exceed the upper or lower tolerance band limit), the corresponding error code (309, 310) is indi-
cated and the alarm output is switched.
An additional delay time (0…9.9s) can be set in the ROPEX visualization software. The first time the lower toler-
ance band limit is exceeded, the temperature diagnosis is not activated until the parameterized delay time has
elapsed. The temperature diagnosis function can thus be explicitly deactivated, e.g. if the temperature drops tem-
porarily owing to the closure of the sealing jaws.
The values that can be set in the ROPEX visualization software for the upper and lower tolerance band are iden-
tical to those for the "Temperature OK" signal (MOD 46).
7.10 Heatup timeout (as of April 2005)
An additional heatup timeout can be activated in the ROPEX visualization software (  section 7.11 "Diagnostic
interface/visualization software (as of April 2005)" on page 33).
This timeout starts when the START signal is activated. The RES-407 then monitors the time required for the
ACTUAL temperature to reach 95% of the SET temperature. If this time is longer than the parameterized time, the
corresponding error code (304) is indicated and the alarm output is switched (
 section 7.13 "Error messages" on
page 34).
