Installation and Mounting
CSP2008
4.3.1.1 Power Supply
Connect the inputs
24 V
and
0 V
to a 24 V power supply.
MICRO-EPSILON recommends the use of the optionally available power supply PS2020
for the controller. Features: DIN rail mounting, input 230 VAC, output 24 VDC/2.5 A.

4.3.1.2 Laser Switch On
The digital input has overload and reverse polarity protection.
Connect the inputs
Laser
and
GND
in order to switch on the laser beam of the con-
nected sensors, see Fig. 7 , see Fig. 10 .
A connection of the input to
GND
using a button or a transistor (NPN - Open Collector) is
sufficient for starting.
The laser beam of the connected sensors is switched off for open inputs.

4.3.1.3 Inputs for Reset, Synchronization and Triggering
The digital inputs have overload and reverse polarity protection.
Connect the inputs
Zero
or
Sync/Trig
to
GND
in order to initiate the function, see
Fig. 7 , see Fig. 10 .
A connection of the input to
GND
using a button or a transistor (NPN - Open Collector) is
sufficient for starting.
The direction (LOW or HIGH) of the activated input
Sync/Trig
or reset (
Zero)
is speci-
fied in the basic settings of the terminal block, see Chap. 5.3.6.1 .
