Heat-up time monitoring
An additional heat-up time monitoring can be activated with the ROPEX visualisation software (
"USB-interface for visualisation software ROPEXvisual
The heating-up time monitoring is activated when the START signal is switched on. The RESISTRON
®
Temperature Controller RES-5008 then monitors the time till the ACTUAL temperature reaches 95 % of the
SETPOINT temperature. If the heating-up time takes longer than the parametrised time, error no. 304 is output
and the alarm output switches on (
section 9.25 "Error messages" on page 48).
Possible causes for the response of the heating-up time monitoring:
• Impulse transformer incorrectly dimensioned
• Heating-up time monitoring parametrisation too small
• Lines too long or defective
• Incorrect contact

Restart delay after Reset
After acknowledging an alarm with the RESET signal, the RESISTRON
®
Temperature Controller RES-5008 waits
until any contactor Kb connected has closed the heating circuit again. Only after this waiting time has elapsed
measuring pulses are generated in order to determine the current ACTUAL temperature and to carry out error
diagnostics.
This restart delay is 0.2 s by default and can be adjusted with the parameter „Restart delay after Reset“. This
allows slower switching contactors to be used.
NOTE
The user can only set the restart delay after Reset with the ROPEX visualisation software
(
Chapter 9.20 “USB interface for the visualisation software ROPEXvisual
®
” on page 45).
