RES-5007

Version 1

If the temperature diagnosis has not switched on before the START signal is deactivated (i.e. The ACTUAL tem-
perature has not exceeded the lower tolerance band limit or dropped below the upper tolerance band limit), the
related error no. 309, 310 is output and the alarm relay switches on.
A delay time (0...9.9 s.) can also be set with the ROPEX visualisation software. After the lower tolerance band limit
is exceeded, the temperature diagnosis takes place only after the parameterised delay time has expired. As a
result, the temperature diagnosis can be intentionally suppressed, such as during a temperature drop caused by
closing the welding jaws.

 is active

Heat-up time monitoring

An additional heat-up time monitoring can be activated with the ROPEX visualisation software (

section 8.11

"USB interface for visualisation software ROPEXvisual

®

" on page 27).

This monitoring is activated when the START signal is switched on. The RES-5007 then monitors the time until
the ACTUAL temperature has reached 95% of the setpoint temperature. If this takes longer than the parameter-
ised time, error no. 304 is output and the alarm output switches on (

section 8.16 "Error messages" on page 29).
