The fail-safe shutter can be closed manually by pressing the push button
“Hand“ (see
the graphic) on the front panel of the control electronics or by parameterising the de
vice settings:
Setting path:
> Specific parameters > D-R 290 configuration > Fail-safe shutter 1 present
or
> Specific parameters > D-R 290 configuration > Fail-safe shutter 2 present
to "0" via D−ESI 100 or D−ISC 100. To activate the shutter function this parameter
must be reset to "1".
The checking for correct operation is performed …
… automatically when the D-SK AE is connected to the measuring head D−R 290. A
brief test is performed every 24 hours.
… manually when the D-SK AE is connected to the measuring head D−R 290 and the
manual test function for the fail-safe shutter is tested.
