Temperature diagnosis
An additional temperature diagnosis can be activated with the ROPEX visualisation software (
"USB interface for visualisation software ROPEXvisual
" on page 27). Here, the RES-5007 checks whether the
ACTUAL temperature lies within a settable “good window” tolerance band around the SETPOINT temperature.
The lower (
) and upper (
) tolerance band limit are set at the factory to -10 K and +10 K, respectively.
These values can be set separately from each other with the ROPEX visualisation software.
After activation of the START signal, if the ACTUAL temperature lies within the specified tolerance band, the tem-
perature diagnosis is switched on. If the ACTUAL temperature leaves the tolerance band, the related error no.
307, 308 is output and the alarm output switches on (
section 8.16 "Error messages" on page 29).
