10.10 Temperature diagnosis
(as of February 2007)
An additional temperature diagnosis can be activated in
the ROPEX visualization software (
 section 10.12
"Diagnostic interface / visualization software (as of
February 2007)" on page 43). The RES-409 checks
whether the ACTUAL temperature is within a settable
tolerance band ("OK" window) 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
visualization software.
If the ACTUAL temperature is inside the specified
tolerance band when a START command is sent via the
CAN interface - or a 24VDC signal (START 0 or
START 1) is activated - the temperature diagnosis is
also activated. If the ACTUAL temperature leaves the
tolerance band, the corresponding error code
(307 or 308) is indicated and the fault output is
switched (
 section 10.16 "Error messages" on
page 45).
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 or 310) is indicated and the fault relay is switched.
An additional delay time (0..9.9s) can be set via the
CAN interface (CAN message address 10) or 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 because the sealing
jaws are closed.
The values that can be set in the ROPEX
visualization software for the upper and
lower tolerance band are identical to those for the
"Temperature OK" bit. These values are
transferred with CAN message address 7 (or
addresses D and E).
10.11 Heatup timeout
(as of February 2007)
An additional heatup timeout can be activated either in
the ROPEX visualization software (
 section 10.12
"Diagnostic interface / visualization software (as of
February 2007)" on page 43) or via the CAN interface
(CAN message address 11). This timeout starts as
soon as any START command is received via the CAN
interface (or the 24VDC START 0 signal is activated).
The RES-409 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
