RES-5011
Version 2
The "OUTPUT" LED blinks several times when the AUTOCOMP function is executed and the actual value
output (terminals 17+18) changes to 0…3 °C (corresponds to approx. 0 VDC).
The AUTOCOMP function must be activated in the parameter data (
section 8.7 "Parameter object (class:
0x0F)" on page 28) (default setting: AUTOCOMP off).
8.7.9
Temperature diagnosis
An additional temperature diagnosis can be activated in the parameter data (EDS file). The RES-5011 checks
whether the actual temperature is within a settable tolerance band ("OK" window) either side of the set tempera-
ture. The high (
) and low (
) tolerance limits are the same as for the "Temperature OK" function
(TO bit
section 8.6.6 "Temperature OK (TO)" on page 26). The limits are set to -10 K and +10 K by default.
If the ACTUAL temperature is inside the specified tolerance band when the START signal is activated, the tem-
perature diagnosis is activated as well. If the ACTUAL temperature leaves the tolerance band, the corresponding
error code (307, 308) appears and the alarm relay is switched (
section 8.19 "Error messages" on page 63).
