Synchronization + wire (orange) or synchronization - wire
(orange / black) is short-circuited or disconnected.
Receiver error.
<Test input indicator (orange) lights up>
The device is in the test input condi-
tion. (Device error or interlock setting
error)
<All beam-axis adjustment indicators (red) light up>
The beam channel with its fixed blanking function set into
valid receives light.
The safety input 1 wire (gray) and the safety input 2 wire (gray
/ black) is not wired.
<Operation indicator remains lit in red (light is not received)>
The beam channels are not correctly aligned.
