Integration with relay monitoring as EMERGENCY SHUT-DOWN device
The motor contactors for dangerous movement are connected to both safety relay outputs.
For this purpose, forced contactors have to be used. In the connection diagram, no fuses
are included. However, for correct function fuses are absolutely required. The maximum
contact load of the safety relay outputs is 4A with 24VDC.
The suply of the relay monitoring (EDM) is made from the supply terminals 5, 10 or 11.
Control of the motor contactors happens via K1 and K2. If a contact of K1 and K2 should
fuse together, a message is issued to the TNT 35/7-24V through the feedback circuit
(EDM). A new start of the unit is possible only after removal of the failure in the output
circuit.
5.2.7
Wiring of the message outputs
Two message outputs are integrated in the TNT 35/7-24V. Both are high-active, positive
switching semiconductor outputs and can be connected to potential free inputs of an SPS.
This requires connection to the GND potential of terminal 2, 3 or 6 as reference.
Warning!
The reference potential on terminals 2, 3 and 6 may not be connected with the GND
potential of the machine or the controller.
A faulty connection can damage the device!
