Short-Circuit
Characteristics
of the Output
Channels
If a short-circuit occurs in an output channel, the safety remote device switches off
the affected channel. If multiple short-circuits occur, the channels are switched off
individually in accordance with their power consumption.
If the maximally permitted current for all outputs is exceeded, all outputs are shut
down and cyclically reconnected.
Diagnostics Using the XPSMFWIN programming environment, all the safety remote output
device’s diagnostics can be viewed. Each safety remote device provides diagnostic
signals with reference to their status, error codes, and channel status.
In XPSMFWIN all diagnostic information can be viewed in two ways:
l Using the On-line test function - it can monitor the values of the signals and
variables within the logic plan, while the systems are executing the program.
l Using the Diagnostics window that displays all states of the CPU, COM, and
I/O modules.
SHORT-CIRCUIT CONDITION
The output circuit terminals must not be connected with the connected load. In case
of a short-circuit, the resulting high current may damage the terminals.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
