Operating principle of the 3SU1400-1AA10-.HA0 contact module with installation monitoring
The 3SU1400-1AA10-.HA0 contact module monitors proper installation. If it is incorrectly
installed or is disconnected from the holder (3SU15.0-0AA10-0AA0), the contact module
initiates an automatic shutdown of the machine or system. As long as operation continues, it
is assured that all necessary contacts are functioning properly.
In the case of all actuators except the EMERGENCY STOP actuator, the contact module
with installation monitoring must be mounted at holder position 1 or 2, and in the case of the
EMERGENCY STOP actuator, the module can also be mounted at holder position 3.
Proper mounting (flush with holder) at holder position 1 and 2 causes the first contact to
close, and if the module with installation monitoring is mounted at holder position 3, this
contact does not close until the EMERGENCY STOP actuator is mounted with the holder.
Machinery Directive
In addition to increased safety, the 3SU1400-1AA10-.HA0 contact module also supports
compliance with the Machinery Directive.
During first commissioning:
The circuits are closed and the contact module is ready for use
only after completion of the function test prescribed by the directive, i.e. when activated for
the first time.
During operation:
The installation status of the contact module is continuously monitored. If
an error occurs, the machine is shut down automatically.
