RES-409
Page 49
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 (
"Diagnostic interface / visualization software (as of February 2007)" on page 50) 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 (304) is indicated and the fault relay
is switched (
section 10.16 "Error messages" on page 52).
