8.2.1.4 Cable break monitoring db
Cable break monitoring only functions in range 4...20 mA or 2...10 V.
In range 4-20 mA or 2-10 V the cable break monitoring detects a failure of the set value signal below a determined threshold. This
threshold amounts to 50% of the calibrated minimum value, therefore 2 mA or 1V. At a set value range of 0-20 mA or 0-10 V the
cable break monitoring remains functionless.
The performance of the tensor can be set within the menu.
db
Function Conduct in case of cable break detection
Off (OF) no detection Set value input minimal
Stop (st) STOP Actuator stops immediately
Open (oP) Position OPEN / 100% Actuator drives to 100%
Close (cL) Position CLOSE / 0% Actuator drives to 0%
Position (Po) programmed failure position* Actuator drives into programmed position
* When selecting the menu item Po (position) the current position is saved as failure position. In menu itself the actuator can NOT
be driven into an other position. For changing the failure position, approach the desired position in hand operation, conrm the
selection 'Po' in menu item 'd.b' again. The new position will be saved.
When a cable break is detected the action set in the menu will be performed, the error 'd.b' will be indicated on the display and the
fault message output will be set.
8.2.1.5 Fault message output A.o
(Alarm out)
The contact to the terminals 56 and 57 is closed when the controller is in operation.
The following events will trigger the opening of the signal contact:
• I-ACT is in hand mode
• >> bE: Motor Error
• >> SE: Sensor Error
• >> RE: Range Error
• >> CE: Calibration Error
• >> PE: Parameter Error
• >> db: Drahtbruch (Wire breakage)
• >> Ad: Message deviation
• >> st: Stall Error
Detailed description of errors see chapter 13.1
A.o
Activation:
• Select menu item „Ao“ and conrm with button [M].
• Make a choice on basis of the table below (buttons R / L).
• Finally save new settings with button [M]
