Reading back the calculated TCR value must be done during active control operation, i.e. during an active heating
impulse, as the internal measured value of the current heatsealing band temperature is used for the calculation.
Errors in the calculation of the temperature coefficient are reported with the value 0 (calculated temperature coef-
ficient too low or no active control operation) or 65535 (calculated temperature coefficient too high).
To use the TCR calculator, proceed as follows:
1. The ROPEXvisual
®
visualization software must be unlocked with the password 'ropex3' under 'Settings' -
'Authorize'.
2. In the 'Controller' surface, the TCR calculator is opened with the 'TCR Calculator' icon button:
3. In this surface the externally measured temperature can be entered. During an active heating process, the cal-
culated temperature coefficient is output:
4. The variable temperature coefficient is set in the 'Configuration' surface. For this purpose, the rotary coding
switch for temperature range and alloy on the RESISTRON
®
Temperature Controller RES-5008 must be set to
position 9 PC-CONFIGURATION (
section 8.2.2 "Configuration of the rotary coding switch for temperature
range and alloy" on page 21). After the temperature coefficient has been configured as 'variable', another input
field for the temperature coefficient appears. The previously calculated temperature coefficient is entered here:
5. The elements marked in blue are stored retentively in the RESISTRON
®
Temperature Controller RES-5008.
The settings are thus retained even after a device restart.
