6.3 Solenoid interlock with serial diagnostic function
Solenoid interlocks with serial diagnostic cable have a serial input and
output cable instead of the conventional diagnostic output. If solenoid
interlocks are wired in series, the diagnostic data is transmitted through
the series-wiring of the inputs and outputs.
Max. 31 solenoid interlocks can be wired in series. For the evaluation of
the serial diagnostics line either the PROFIBUS-Gateway SD-I-DP-V0-2
or the Universal-Gateway SD-I-U-... are used. This serial diagnostic
interface is integrated as a slave in an existing field bus system. In this
way, the diagnostic signals can be evaluated by means of a PLC.
The response data and the diagnostic data are automatically and
permanently written in an input byte of the PLC for each solenoid
interlock in the series-wired chain. The request data for each solenoid
interlock is transmitted to the component through an output byte of the
PLC. In case of a communication error between the field bus gateway
and the solenoid interlock, the switching condition of the solenoid
interlock is maintained.
Error
A fault has occurred, which causes the safety outputs to be disabled.
The fault is reset, when the cause is eliminated and bit 7 of the request
byte changes from 1 to 0 or the safety guard is opened. Faults at the
safety outputs are only deleted upon the next release, as the fault
rectification cannot be detected sooner.
Automatic, electronic locking takes place if more than one
fault is detected at the safety outputs or a cross circuit is
detected between Y1 and Y2. This means that normal fault
acknowledgement is no longer possible. To reset this type of
interlocking, the solenoid interlock must be isolated from the
power supply after elimination of the error causes.
Error warning
A fault has occurred, which causes the safety outputs to be disabled
after 30 minutes. The safety outputs initially remain enabled. This
enables the shutdown of the process in a controlled manner. An error
warning is deleted when the cause of error is eliminated.
Diagnostic error (warning)
If an error (warning) is signalled in the response byte, detailed fault
information can be read out.
Accessories for the series-wiring
To provide for a comfortable wiring and series-wiring of SD
components, the connectors and the SD-2V-F-SK SD junction boxes
(variant for the field in closed enclosure) and SD-2V-S-SK (variant for
DIN rail mounting in the control cabinet) are available.
When wiring SD devices, please observe the voltage drop on
the cables and the current carrying capacity of the individual
components.
