Test input The test input must be active when e.g. software is to be downloaded in the controller
(pin 24 to VBB
S
, 10...32 V DC).
Safety-related outputs (MODE byte OUT_Safety) cannot be used with the test input
active. Deactivate the test input and carry out a reset to make them available again.
(Reset = switching on / off of the controller)
During operation of the machine the test input must be connected to GND.
