4.2 Operating mode interface
The operating mode interface consists of the monitored outputs SOM1 … SOM5 (see Block
diagram [ 14] ). "SOM" stands for "Safe Operating Mode". The outputs are assigned to
buttons, which can be used to select an operating mode if they have the relevant authorisa­
tion (transponder key):
Button Output Operating mode
1 SOM1 OM1 The operating mode OM1/OM5 is selected
based on the operating time of button 1 (see
Monitoring of operating time [ 50] )
SOM5 OM5
2 SOM2 OM2
3 SOM3 OM3
4 SOM4 OM4
4.2.1 Switch behaviour after a transponder key is removed
If the transponder key is removed after changing to a different operating mode, it is possible
to configure the subsequent switch behaviour of SOM1 … SOM5. A DIP switch is available
for this purpose (see Control elements [ 10] ).
NOTICE
Please note the following:
– The configuration may only be performed by a competent person.
– The configuration must be performed when the supply voltage is
switched off.
– The configuration is adopted as the device is started up, provided the
switch setting is valid. If not, the device switches to a "Device error"
fault condition.
– During operation, the DIP switch setting is monitored for any change.
If the switch setting is changed during operation, the device switches
to a "Device error" fault condition.
