Lead breakage monitoring
In the case of an error a fault signal is activated across the Power Rail (UPR-05). The power feed module evaluates and passes on the fault
signal by means of a potentially free contact (see system description).
Mode of operation with 2:1 transfer method
The transformer isolated barrier transfers binary signals from the hazardous area by means of the patented new 2:1-transfer method which
allows for the transmission of two independent binary signals by means of a single pair of conductors. This allows wiring to be reduced by 50
%. The 2:1 transfer method is well suited for the transmission of 2 signals that are within close proximity such as Min-Max-manometers, valve
positioners and magnetic immersion probes with two switch points.
Conditions
When using sensors they have to be provided with a reverse polarity protected diode.
Pepperl+Fuchs offers suitable sensors for alternating polarity (see table).
When using mechanical contacts in the 2:1 mode, the blocking diode must be connected near the switch.
Connection of:
Sensors
Comments:
When installing a serial diode, it must be assured that the reverse polarity current is < 0.15 mA, in order to enable the lead monitoring.
For all types NJ, RC/RJ and SJ an adjustment by means of a serial diode is necessary.
Mode of operation without 2:1 transfer method
Set switch S2 to position II.
Refer to the connection
diagrams for lead breakage
and short circuit monitoring.
