The RESTART command
The RESTART command must be sent to the control unit
connecting terminal 15 to the +24Vdc.
The contact used for the RESTART command must be able
to switch a voltage of 24Vdc and a current of 20mA
(guaranteeing a closing time > 100ms). This data is
particularly important in the case of automatic
management of sending of the RESTART command, for
example using a PLC.
The SYSTEM RESET TIME is obtained adding the reset time
of any external contactors K1K2 to the reset time of the
AUS XM control unit (100ms).
In the case of manual activation, a normally open external
button can be used, temporary closing of which generates
the RESTART command.
The Restart command must be installed outside the danger area in a position
where the danger area and the entire work area concerned are clearly visible.
It must not be possible to reach the control from inside the danger area.
The SYSTEM_TEST command
The SYSTEM_TEST command must be forwarded to the control unit
connecting the terminal 16 to the +24Vdc.
The contact used for the SYSTEM_TEST command must be able to
switch a current of 20mA and a voltage of 24Vdc (with a switching time
of > 40ms). The AUS X control unit, after receiving this signal, provides
to switch off the emitters of the connected safety photocells,
The operator must verify the effective stopping of the hazardous
machine (due to the de-activation of the control unit outputs) for all the
time the SYSTEM_TEST command stays active.
The effective stopping of the system must be verified by an operator and
cannot be an operation of the control unit.
