Pilz PSS SB TESTER D - Manual (Page 23)

Operating Manual: PSS SB TESTER 5-5
Separate tests: Short circuits between the bus cable wires
Abbreviations for these separate tests in the “Results” window:
• KS CAN_H/Vcc
• KS CAN_L/Vcc
• KS CAN_H/CAN_GND
• KS CAN_L/CAN_GND
• KS CAN_H/CAN_SHLD
• KS CAN_L/CAN_SHLD
Test for short circuit between the bus cable wires.
The PSS SB TESTER measures the resistance between the wires.
In the detailed display of results from these separate tests, three pieces of
information are displayed: the limit value, the measured value and the
result.
The limit value of 170
Ω
is pre-assigned. If the value measured at the
resistor is less than or equal to the limit value, a short circuit is detected.
Example: limit value 170
Ω
measured value 0
Ω
result: short circuit
INFORMATION
You can use the length measurement to establish the location of a short
circuit between CAN_H and CAN_L, see the section entitled “Length
measurement”.
