1.
Blinks quickly (4 Hz):
The AUTOCAL function must be carried out
(Error Nos. 8 + 9, or 104…106, 211, 302, 303)
2.
Blinks slowly (1 Hz):
System configuration is not correct and therefore the zeroing (AUTOCAL function) carried out was not suc-
cessful (
section 8.2 "Device configuration" on page 20).
(Error nos. 10…12, or 111…114)
3.
Lights up continuously:
Faults prevent commissioning
(Error nos. 101…103, 107, 108, 201…203, 307…310, 9xx)
In cases 1 and 2, when START signal is also activated.
These are usually external wiring errors.
C.)
Alarm relay (relay contacts of terminals 12+13+14):
In the factory setting, the alarm relay is:
•
NOT ACTIVE
in the operating states “Blinks quickly” (B.1) or “Blinks slowly” (B.2). The alarm relay is activated,
however, if a START signal is given in one of these states.
•
ACTIVE
in the operating state “lights up continuously” (B.3).
CAUTION
If the alarm relay is configured differently than in the factory setting (
tion of the alarm relay" on page 22) these statuses are inverted.
D.)
Output of the error number via the actual value output 0…10 VDC (terminals 17+7):
As a temperature display is not required in case of malfunction, the actual value output is used to output the error,
in case of alarm.
• 13 voltage levels are available within the 0…10 VDC range.
An error number is assigned to every voltage level (
section 9.25 "Error messages" on page 48).
• In case of error nos. 104…106, 211, 302, 303 (AUTOCAL must be carried out) and in case of error
nos. 111…114, (system configuration is not correct) the actual value output alternates between the voltage
value that corresponds to the error and the final value (10 VDC, i.e. 300 °C or 500 °C) with 1 Hz. If the START
signal is given, the voltage value does not change any more.
• An error message can be reset by applying the “RESET” signal or switching the controller off and on. The error
message is reset only when the button is released.
Invalid error messages can occur when the controller is switched off due to the undefined operating status.
This must be taken into account while evaluating the higher-level controller (e.g. SPS), to avoid false alarms.
