Service and Commissioning Support
Forcing RTDs*
* = Availability depends on ordered device.
The parameters, their defaults, and setting ranges have to be taken from
RTD/UTRD section.
Principle – General Use
The User MUST ENSURE that the RTDs operate normally after the
maintenance is completed.
If the RTDs do not operate normally, the protective
device WILL NOT provide protection.
For commissioning purposes or for maintenance, RTD temperatures can be set by force.
Within this mode [Service/Test Mode/URTD], RTD temperatures can be set by force:
Permanent; or
Via timeout.
If they are set with a timeout, they will keep their “Forced Temperature” only as long as this timer runs. If the timer
expires, the RTD will operate normally. If they are set as »
Permanent«, they will keep the “Forced Temperature”
continuously. This menu will show the measured values of the RTDs 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 RTD values. As soon as the force mode is deactivated, measured values
will be shown again.
