Modifications (MODs)
RES-403

MOD 40
Additional terminal for "Temperature reached" signal.
This output signal is activated when the ACTUAL
temperature of the heatsealing band exceeds 95% of
the SET heatsealing temperature. It can be used to
monitor the process, for example, or to control the
closure of the heatsealing bars.
MOD 40 cannot be used in combination with
MOD 26 (booster connection) manufactured
prior to September 2005.
MOD 46 (as of October 2005)
Additional terminal for "Temperature OK" signal. If this
modification is installed, 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
visualization software (
ª
section 6.10 "Diagnostic
interface/visualization software (as of October 2005)"
on page 25).
If the actual temperature is inside the specified
tolerance band when the "START" signal is activated,
the output signal is activated as well (see graph below):
If the actual temperature leaves the tolerance band, the
output signal is deactivated again. The output signal
then remains deactivated, even if the actual tempera-
ture subsequently returns to the tolerance band.
It is thus possible to check - as part of the monitoring
concept, for instance - whether the output signal is still
active at the end of the heatsealing process, in other
words whether the actual temperature has remained
within the defined tolerance band throughout the entire
process.
The output signal is not deactivated again until the next
"START" signal is activated or until an alarm is
signaled.
MOD 46 ("Temperature OK" signal) cannot be
used in combination with MOD 40
("Temperature reached" signal).
