Connecting devices
4.2.3 Transponder (e.g. SICK T4000 Compact and T4000 Direct)
Electrical connection: Example from Setting and Monitoring Tool with WS0-XTIO
T4000 Compact
(connected to 24 V) 24 V at +LA, I1 at LA
24 V at +LB, I2 at LB
T4000 Compact
(connected to test output) X1 at +LA, I3 at LA
X2 at +LB, I4 at LB
T4000 Direct (with OSSD) 24 V at UB (T4000), I5 at OA
24 V at UB (T4000), I6 at OB
Function Notes
Testing Possible for T4000 Compact
Not necessary for T4000 Direct, since self monitored
Series connection/
cascading T4000 Compact is not cascadable;
Take the max. line resistance of 100
Ω into account at the T4000
(see Chapter 12)
For further information refer to the manuals of the Transponder SICK T4000 Compact
or T4000 Direct or in the manuals of devices used.
4.3 Testable single-beam photoelectric safety
switches
4.3.1 Testable Type 2 single-beam photoelectric safety switches
Electrical connection: Example from Setting and Monitoring Tool with WS0-XTIO
SICK Wx12/18/24/27,
Vx18 Test input TE (transmitter) at X1
Output Q (receiver) at I1
SICK L21, L27/L28 Test input TE (transmitter) at X2
Output Q (receiver) at I2
Use protected or separate cabling for the test output of the module (X1...X8) to the test
input of the transmitter and for the output of the receiver to the safe input of the
module (I1...I8). Otherwise a cross circuit between these signals can inhibit the error
detection by this test.
