7. The following statuses can then result:
8. With a cold heating element, activate the AUTOCAL function (terminal 5+13). The yellow “AUTOCAL” LED
lights up for the duration of the calibration process (approx. 10…15 seconds). During this process, a voltage of
approx. 0 V is output at the actual value output (terminal 17+13). A connected ATR-x shows 0…3 °C.
After zeroing is completed, the “AUTOCAL” LED goes out, and a voltage of 0.66 V (in 300 °C range) or 0.4 V
(in 500 °C range) is set at the actual value output. A connected ATR x must be on the “Z” marking.
If zeroing was not performed correctly, the red “ALARM” LED flashes slowly (1 Hz). Then configuration of the
controller is not correct (
section 7.2 "Device configuration" on page 14, ROPEX application report). After
device configuration is correct, perform zeroing again.
9. After successful zeroing, specify a defined temperature at the setpoint value input (terminal 16) and apply the
START signal (HEAT). “HEAT” LED then lights up. The heat-up and control procedure can be observed at the
actual value output:
It is functioning correctly when the temperature (i.e. signal change at the analogue output) is steady, that is,
does not jump, oscillate or even go briefly in the wrong direction. Such behaviour indicates an incorrect place-
ment of the U
R
measurement line.
When an error message is issued, proceed according to section 8.16 "Error messages" on page 29.
10.Burning in the heating element (
section 7.3.1 "Burning in the heating element" on page 15) and repeat
AUTOCAL function.
7.4.2
Placing back into operation after changing the heating element
When changing the heating element, proceed according to section 7.3.1 "Burning in the heating element" on
page 15.
Pay attention to correct alloys, dimensions and copper coating of the new heating element to avoid
malfunctions and overheating.
