Function description
The device enables you to switch between 5 different operating modes (operating modes
OM1 … OM4 and special operating mode OM5 (Service)) and enables access restriction
via the authentication system PITreader.
4 inputs are available for OM1 … OM4, for connecting external pushbuttons. For the spe-
cial operating mode OM5 (Service), the pushbutton for OM1 must be operated for a certain
Monitoring of operating time [
). Each input (pushbutton) is assigned a
monitored semiconductor output (see
). Operating the
pushbutton switches the semiconductor output from a "0" signal to a "1" signal. The device
guarantees that only one of the semiconductor outputs has a "1" signal at any one time.
INFORMATION
OM storage of operating mode
When configured with OM storage (see
), after a restart the unit will start with the last selected
operating mode.
If OM storage is
not
configured, the unit always starts with OM1. For this
reason you should make sure that OM1 represents the safest operating
mode.
