USE
The connector X113 test device has been developed to allow quick fault-finding on the safety chains; in fact
it makes it possible to display the motor switching on chain and the internal and external safety chain through
a simplified wiring diagram which represents these circuits and a set of leds which allow quick identification
of a fault if it occurs.
In addition it is possible to perform tests through a set of microswitches to further simplify fault-finding.
CONNECTION
Connect the device on connector X113/SDB3 inside the controller (see previous figure)
