RES-407
Page 9
MOD 46 (as of April 2005)
Additional terminal for "Temperature OK" signal. If this
modification is installed, the RES-407 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
interface/visualization software (as of April 2005)" on
page 31).
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).
