9.8 Temperature diagnosis
(as of October 2005)
An additional temperature diagnosis can be activated in
the ROPEX visualization software (
ª section 9.10
"Diagnostic interface/visualization software (as of
October 2005)" on page 30). The RES-403 checks
whether the ACTUAL temperature is within a settable
tolerance band ("OK" window) on either side of the SET
temperature. The lower (
) and upper
( ) tolerance band limits are configured in the
factory to -10K and +10K. These values can be set
independently of one another in the ROPEX visualiza-
tion software.
If the actual temperature is inside the specified tole-
rance band when the "START" signal is activated, the
temperature diagnosis is activated as well. If the
ACTUAL temperature leaves the tolerance band, the
corresponding error code (307 or 308) is indicated and
the alarm relay is switched (
ª section 9.12 "Error mes-
sages" on page 31).
If the temperature diagnosis is not activated by the time
the "START" signal is deactivated (i.e. if the ACTUAL
temperature does not exceed the upper or lower
tolerance band limit), the corresponding error code
(309, 310) is indicated 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 dia-
gnosis is not activated until the parameterized delay
time has elapsed. The temperature diagnosis function
can thus be explicitly deactivated, e.g. if the tempera-
ture drops temporarily 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 and the delay time are iden-
tical to those for the "Temperature OK" signal
(MOD 46).
9.9 Heatup timeout
(as of October 2005)
An additional heatup timeout can be activated in the
ROPEX visualization software (
ª section 9.10 "Dia-
gnostic interface/visualization software (as of October
2005)" on page 30).
This timeout starts when the START signal is activated.
The RES-403 then monitors the time required for the
ACTUAL temperature to reach 95% of the SET tempe-
rature. If this time is longer than the parameterized
time, the corresponding error code (304) is indicated
and the alarm relay is switched (
ª section 9.12 "Error
messages" on page 31).
