Service and Commissioning Support
Forcing Analog Outputs*
* = Availability depends on ordered device.
The parameters, their defaults, and setting ranges have to be taken from
Analog Output section.
Principle – General Use
The User MUST ENSURE that the Analog Outputs operate normally after
maintenance is completed.
Do not use this mode if forced Analog Outputs
cause issues in external processes.
For commissioning purposes or for maintenance, Analog Outputs can be set by force.
Within this mode [Service/Test Mode/Analog Output(x)], Analog Outputs can be set by force:
Permanent; or
Via timeout.
If they are set with a timeout, they will only keep their “Forced Value” as long as this timer runs. If the timer expires,
the Analog Output will operate normally. If they are set as »
Permanent«, they will keep the “Forced Value”
continuously. This menu will show the current value that is assigned onto the Analog Output until the User activates
the force mode by calling up the »
Function«. As soon as the force mode is activated, the shown values will be
frozen as long as this mode is active. Now the User can force Analog Output values. As soon as the force mode is
deactivated, measured values will be shown again.
