8 Operation
The switch must be installed and operated only by authorized persons. Do not use any hard objects for
making entries. After being switched on the Switch 2000 / TempSwitch 2000 runs through a self-test.
Operation via three plastic film keys is menu-driven. These keys must not be touched with hard objects! If
an error is recognized during the self-test or during operation, this is signalled by the (yellow) flashing
alarm LED (AL).
The error can be read out in the menu . The green LEDs S1 and S2 signal the activity of the two
switching points.
