Disposal
The module must be disposed of properly when it reaches the end of its
service life.

Operating Manual: PSS SB TESTER 4-1
Operation
Supply
The PSS SB TESTER is supplied via a battery, which is located in the
back of the housing.
A charged PSS SB TESTER can be operated for 1 to 2 hours, depending
on the application conditions. If the battery charge drops to a particular
value during testing, the message “Charge battery” will be displayed and a
beep will sound. If the battery charge becomes so weak that the supply
can no longer be guaranteed, the PSS SB TESTER will switch off
automatically. The battery will need to be recharged. This takes approx. 1.5
hours.
INFORMATION
When the PSS SB TESTER is used for the first time or after storage
periods of more than 6 months, the battery will need to be charged for at
least 4 hours.
Charging the battery
• Plug the charger’s mains connector into a socket (110/230 VAC, 50 Hz).
• Take the PSS SB TESTER battery and plug it into the charger. The
charger is designed in such a way that the battery can only be inserted at
the correct polarity.
The start of the charging process is displayed via a red LED on the
charger’s connector (100 % on).
When the main charge is complete, the charger automatically switches to
“Conservation charging” mode and the LED flashes (25 % on, 75 % off).
If the main charge cannot be completed within 2 ½ hours, the charger
automatically switches to “Conservation charging” mode.
If the battery is extremely depleted, the LED will flash (50 % on, 50 % off)
when the battery is plugged into the charger.The battery is then charged
with a reduced charging current until the battery is regenerated and can be
switched to “normal” main charge mode.

Operation
4-2 Operating Manual: PSS SB TESTER
INFORMATION
The battery should not be left in the charger over a long period of time
(several weeks).
• Charge the battery until the LED on the charger flashes (25 % on, 75 %
off)
• Remove the battery and place in the PSS SB TESTER.

Operation
4-6 Operating Manual: PSS SB TESTER
Performing the tests
All the tests are described in detail in the chapter entitled “Tests/
Measurements”. This section is only intended to explain how to save,
upload and delete the test results.
Saving the test results
With the exception of the results for real-time mode, all the test results can
be saved.
The connection test, screening test, signal test and length measurement
each have a specific memory area available within the PSS SB TESTER.
This division within the memory enables tests to be performed at different
times; the respective results can be saved and then all the results can be
uploaded to the PC together. When you save the results of a test, the old
data in the test's memory area is overwritten.
Example: The user performs the connection test, saves the results and
switches off the tester. Two hours later the user then performs the signal
test, stores the results and again switches off the tester.
The current results from the connection test and signal test are saved
within the tester, along with the results from an earlier length
measurement.
• After carrying out a test, switch to the “Start” window and press F3.
• The “Memory” window opens. Use the arrow keys to move the cursor to
the symbol for “Save” and press VAL.
• The “Save” window opens. Press VAL.
The test results are saved. A message confirms that the results have been
saved. The “Start” window is then displayed again.
The test results are 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.

Operating Manual: PSS SB TESTER 4-7
Uploading the test results to a PC
The saved results can be uploaded to a PC, where they can be saved as a
text file.
• Connect the PSS SB TESTER to a USB port on the PC.
• Start the “PSS SB TESTER” software (see Chapter 6).
• Click the “Upload” button.
• The “Save as” window is opened. Enter the directory and the name of the
file in which the test results are to be saved.
• The data is uploaded and saved. When the upload is complete, close the
“Upload of the results” window.
The file containing the results is displayed in a standard text editor.
Deleting the test results
Before each series of tests, the memory containing the test results should
be cleared to avoid mixing up new results with the results from previous
tests. Then it will no longer be possible to upload results to the PC.
• Press F3 in the “Start” window.
• The “Memory” window opens. Use the arrow keys to move the cursor to
the symbol for “Delete” and press VAL.
• The “Delete” window opens. Press VAL.
The test results are deleted. A message confirms that the results have
been deleted. The “Start” window is then displayed again.

Operating Manual: PSS SB TESTER 5-1
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. The PSS SB TESTER therefore has a
SafetyBUS p interface. The 9-pin connector on the supplied cable is
attached to this interface. The adapter on the other end of the cable is
attached between a SafetyBUS p device and the SafetyBUS p cable. The
point at which the PSS SB TESTER must be added depends on the test or
measurement that is to be performed.

Tests/Measurements
5-2 Operating Manual: PSS SB TESTER
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
• Test for short circuit between CAN_L and CAN_GND
• Test for short circuit between CAN_H and CAN_SHLD
• Test for short circuit between CAN_L and CAN_SHLD
The connection test corresponds to a resistance measurement.
The tester also detects components between the cables that are not
resistors (diodes, capacitors, ...).
Where resistance values are low (0 ... 1000 Ohm), the measuring accuracy
of the tester reaches the order of ± 5 %, if no capacitors or diodes are
found.
Performing the connection test
• Add the PSS SB TESTER at any point within SafetyBUS p.
• Switch on the PSS SB TESTER.
• Highlight the symbol in the “Start” window and press VAL.
• The “SafetyBUS p” window opens, in which you can select the test/
measurement. Use the arrow keys to move the cursor to the symbol for
“Connection test” and press VAL.
• The following question is displayed: “SafetyBUS p is switched off?”.
Make sure that SafetyBUS p is switched off, i.e. all devices on
SafetyBUS p must be switched off and there must be no voltage present
on the “Vcc” line.
Then press VAL.
