b Sensor short-circuit.
b Actuator short-circuit.
Use of contact 2 diagnostics function (M12 connector)
Advantys FTM splitter boxes allow the use of sensors and actuators incorporating an
integrated diagnostics function (DESINA type). Configuring contact 2 of each M12
connector as a diagnostic input enables detection of external faults associated with
the sensors or actuators.
This information enables the following faults to be detected:
b damage to the detection surface,
b faulty electronics,
b no load.
Selection of either the sensor input or diagnostic input function on contact 2 is made
channel by channel, by entering parameters, when configuring the splitter box.
Fault indication by a red LED is possible for each channel configured as a diagnostic
input.
Example of connection of a sensor with integrated diagnostics function:
Using the M12 diagnostics adaptor accessory FTX DG12, it is possible to monitor
breaks in wiring to sensors or actuators which do not have an integrated diagnostics
function (only applicable to splitter boxes fitted with M12 connectors).
