Functions
Selection of signal type per channel
b Each M12, 5-pin connector on Advantys FTM splitter boxes allows the connection
of 2 signals. Depending on the type of splitter box, these can be:
v 1 sensor input signal,
v 1 diagnostic input signal,
v 1 actuator output signal.
Signal type, depending on digital splitter box selected:
FTM 1DD FTM 1DE
M12 and M8 Contact 4 Input
Output Input
M12 Contact 2 Input
Output
Diagnostic Input
Diagnostic
Note: either a normally open (N/O) or a normally closed (N/C) contact can be chosen for each
input signal.
Diagnostics
Each Advantys FTM splitter box has one LED per channel to indicate the status of
the channel and to enable fast and precise location of a fault. Fault monitoring
diagnostics are indicated on the splitter box by LEDs and are fed back to the control
system (PLC) via the bus.
There are 2 levels of diagnostics:
b diagnostics per channel,
b diagnostics per splitter box.
Diagnostics per channel
b Sensor short-circuit
A short-circuit or overload on contact 1 of the M12 or M8 female connector blows
the self-resetting fuse. Each M12 or M8 connector is individually protected. A red
LED indicates the fault on the corresponding M12 or M8 connector. This fault is
signalled to the Master. Supply to the sensors is automatically restored after
elimination of the fault.
b Actuator short-circuit
A short-circuit or overload of an output causes a reset of this output. The fault is
signalled to the Master. A red LED indicates the fault on the corresponding M12 or
M8 connector. The output does not restart automatically. After having eliminated the
cause of the fault, the channel must be reset by the PLC. This operation erases the
short-circuit memory.
b Actuator warning
When the output is at state 0, the contact corresponding to the M12 or M8 female
connector is checked for presence of 24 V voltage. If + 24 V is present, it means
there is a “short-circuit”. A red LED indicates the fault on the corresponding M12 or
M8 connector. The fault is signalled to the Master.
