Notice !
For connecting BUS IN and BUS OUT we recommend our ready-made Interbus cables (see
chapter 10.8 "Accessory ready-made cables for interface connection" on page 10 3 ).
Attention !
The laser measurement system can be used to branch out the Interbus network. The con-
tinuing network is connected via BUS OUT .
The integrated SUPI (Serial Universal Peripheral Interface) automatically detects whether
additional participants are connected to BUS OUT. Termination of BUS OUT is not neces-
sary.
8 . 3 .4.2 Shielding and grounding concept
The cable shielding must be concentric and have the largest possible surface area on the
M 12 connector (thread).
The M 12 thread for BUS IN is connected to the functional earth (FE) inside the AMS 200 via
an RC element (1M
Ω
|| 15nF).
The M 12 thread for BUS OUT is conductively connected to the housing and is thus directly
connected to the functional earth (FE).

Input/output 1, by default:
Input : low (0 V) = laser on,
high (VIN) = laser off
3 GND Supply voltage 0 V DC
4 I/O 2
Input/output 2, by default:
Output : low (0 V) = velocity limit value exceeded
high (VIN) = below velocity limit value
