Modifications (MODs)
Version 1
RES-403
Page 45
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 (
"Diagnostic interface/visualization software (as of October 2005)" on page 32).
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 temperature 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).
