NOTE: Switch SW2 is located on the printed circuit board inside the control unit.
The state of all 4 single switches of SW2 will be read, stored and activated by the control units
microprocessor if the CODE-button on the front is pressed and hold for more than 3 sec. when
switching on the control unit.
After this 3 sec. the green "ON" led on the front turns on (lights up), indicating that the process
is finished successful.
When the control unit is connected to the power supply, this SW2-reading-process can also
easily be initiated by pulling out the fuse F1/5A and push it back into its socked.

If a handswitch with an ordinary ON/OFF switch is used, (not failsafe) the control unit CU212-1S has to be set
for NOT FAILSAFE operation:
To set the control unit for using a failsave CB212-1S handswitch, set SW2-4 to ON
