9.4.7 Temperature diagnosis
An additional temperature diagnosis can be activated in the parameter data. The RESISTRON
®
Temperature
Controller RES-5009 checks if the ACTUAL temperature within an settable tolerance band “OK window” is found
on either side of the SETPOINT temperature. The lower (
) and upper ( ) tolerance band limits are
the same as with the “Temperature OK” monitoring (TO bit,  section 9.3.6 "Temperature OK (TO)" on page 35).
The limits are set at the factory to -10 K and +10 K, respectively.
If the ACTUAL temperature is within the specified tolerance band after activation of the START signal, the tem-
perature diagnosis will be switched on. If the ACTUAL temperature leaves the tolerance band, the related error
nos. 307, 308 are output and the alarm output switches on (
 section 9.15 "Error messages" on page 49).
If the temperature diagnosis has not been activated before the START signal is deactivated (i. e. the ACTUAL tem-
perature has not exceeded the lower tolerance band limit or has not dropped below the upper tolerance band limit),
the related error nos. 309, 310 are output and the alarm relay switches on.
A delay time (0…9.9 s) can additionally be set in the parameter data. After the lower tolerance band limit is
exceeded, the temperature diagnosis takes place only after the parametrised delay time has expired. As a result,
the temperature diagnosis can be intentionally suppressed, e. g. during a temperature drop caused by closing the
tool.
The lower and upper tolerance band limits cannot be set through the ROPEX visualisation software. These are
the same limits as with the TO bit. These can only be set via the parameter data (
 section 9.4 "Parameter data"
on page 37).

9.4.8 Heat-up time monitoring
An additional heat-up time monitoring can be activated in the parameter data.
The heat-up time monitoring is activated with the start request. The RESISTRON
®
Temperature Controller
RES-5009 then monitors the time until the ACTUAL temperature has reached 95% of the setpoint temperature. If
