Controller functions
Page 30 RES-407 Version 1
The "AUTOCOMP" function must be activated in the ROPEX visualization software (  section 7.11 "Diagnostic
interface/visualization software (as of April 2005)" on page 33) (default setting: AUTOCOMP off).
The following settings are possible:
1.
„OFF" (Factory settings)
The „AUTOCOMP“ function is deactivated.
2. „ON“
The „AUTOCOMP“ function is executed whenever the "AUTOCAL" function (  section 7.4 "Automatic zero
calibration (AUTOCAL)" on page 26) is run twice in quick succession. The interval between the end of the first
"AUTOCAL" function and the start of the second "AUTOCAL" must be shorter than 2.0s. The second
"AUTOCAL" function only takes around 2.0s and incorporates the "AUTOCOMP" function.
If the interval between the two "AUTOCAL" functions is longer than 2.0s, "AUTOCAL" is executed normally
again the second time.
The "OUTPUT" LED blinks repeatedly when the "AUTOCOMP" function is executed and the actual value
output (terminals 17+14) is set to 0…3°C (i.e. app. 0 VDC).
3. „AUTO“
(as of software revision 108)
With this setting the „AUTOCOMP“ function is activated automatically after the "AUTOCAL" function has been
successfully executed.
