    Operation The information on the backlight is stored in a memory that is supplied by the battery. If the battery is removed, the contents of the memory will be retained for 10 minutes. If it takes longer for the battery to be replaced, the contents of the memory will be lost.

  • Page 15: Setting The Signal Runtime

    The ex-works setting for the signal runtime is 4.5 ns/m. This value is valid for the Pilz standard cable for SafetyBUS p (order no. 311 070). If you use a cable with a different signal runtime, you will need to amend the set value.

  • Page 19: Tests/Measurements

    Tests/Measurements The PSS SB TESTER can be used to perform various tests and measurements on SafetyBUS p: • Connection test • Screening test • Length measurement • Signal test • Real-time measurements These tests and measurements are described in this chapter. To be able to carry out the measurements, the PSS SB TESTER will need to be added to SafetyBUS p.

  • Page 20: Connection Test

    Tests/Measurements Connection test The connection test comprises the following separate tests: • Measuring the resistance between CAN_H and CAN_L • Test for short circuit between CAN_H and Vcc • Test for short circuit between CAN_L and Vcc • Test for short circuit between CAN_H and CAN_GND •...
  • Page 21 The PSS SB TESTER then checks whether “Vcc” is without voltage. If this is the case, the test is performed and the following message appears on the display: “Connection test in progress”. If voltage is present at “Vcc”, the test will not be carried out because the test results could be corrupted or the Tester could be damaged.

  • Page 22: Separate Test: Resistance Between Can_H And Can_L

    Tests/Measurements Separate test: Resistance between CAN_H and CAN_L Abbreviation for this separate test in the “Results” window: R CAN_H/CAN_L Measurement of the resistance between CAN_H and CAN_L. You can use this measurement to detect whether the terminating resistors are present and whether they are the correct size (120 Ω...

  • Page 23: Separate Tests: Short Circuits Between The Bus Cable Wires

    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.

  • Page 24: Screening Test

    Tests/Measurements Screening test The screening test can be used to check for breaks in the cable screening. You can therefore determine whether the cable screening is attached correctly to each bus connector. The screening test corresponds to a resistance measurement between CAN_H and CAN_SHLD.
