8.3.4
Forcing RTDs*
* = Availability depends on ordered device.
NOTICE!
The parameters, their defaults, and setting ranges have to be taken from RTD/UTRD
section.
Principle – General Use
DANGER!
The User MUST ENSURE that the RTDs operate normally after 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 (Prot inhibit) / WARNING! Cont? / 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 again be shown.
