RES-5012
Version 2
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 high or low tolerance band limit), the corresponding error code (309, 310) appears
and the alarm relay is switched.
An additional delay time (0..9.9 s) can be set in the parameter data (ESI file). The first time the low tolerance limit
is exceeded, the temperature diagnosis is not activated until the configured delay time has elapsed. The tempera-
ture diagnosis function can thus be selectively deactivated, e.g. if the temperature drops temporarily owing to the
closure of the sealing jaws.
The high and low tolerance limits cannot be set in the ROPEX visualization software. The same limits apply as
with the TO bit. They can only be set in the parameter data (
section 8.7 "Object dictionary" on page 30).
8.7.10 Heatup timeout
An additional heatup timeout can be activated in the parameter data (ESI file).
This timeout starts when the ST bit is set. The RES-5012 then monitors the time required for the ACTUAL tem-
perature to reach 95% of the SET temperature. If this time is longer than the configured time, the corresponding
error code (304) appears and the alarm relay is switched (
section 8.19 "Error messages" on page 50).
The "Heatup timeout" function must be enabled for use in the parameter data (
section 8.7 "Object dictionary"
on page 30) (default setting: heatup timeout off).
