error  code  (307 or 308)  is  indicated  and  the  alarm  relay  is  switched  (

section 11.21  "Error  messages"  on

page 52).

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 relay is switched.
An additional delay time (0..9.9s) can be set in the ROPEX visualization software. The first time the lower tolerance
band limit is exceeded, the temperature diagnosis is not activated until the parameterized delay time has elapsed.
The temperature diagnosis function can thus be selectively deactivated, e.g. if the temperature drops temporarily
owing to the closure of the sealing jaws.

11.16 Heatup timeout (as of June 2006)

An additional heatup timeout can be activated in the ROPEX visualization software (

section 11.19 "Diagnostic

interface / visualization software (as of June 2006)" on page 51).
This timeout starts when the START signal is activated. The RES-408 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 relay is switched (

section 11.21 "Error messages" on

page 52).
