1.1 Safety instructions
WARNING:
Comply with the higher ranking "Safety Instructions" in Chapter "Operational Safety" in the User
Manual and Service Manual.
The placement machines SIPLACE are powered by mains voltage.
Portions of the system are therefore conducting dangerous electricity, inside the machine even
while the master switch is turned off.
Death, serious injury or considerable damage may result if these automatic placement systems
are handled incorrectly.
After you have properly carried out the shut-down of the operating system:
Before all work the machine must be turned off at the main switch and isolated from the mains. In
addition, the compressed air supply must be turned off at the main valve of the compressed air
unit in the machine base.
Danger:
For anyone wearing a heart pacemaker it is not permitted to work near linear motors, as described
in detail in the User Manual and the Service Manual, Chapter "Special Safety Instructions when
working in vivinty of powerful magnetic fields" .
Obey the applicable accident prevention regulations, DIN standards and special safety codes of
your country at all times. DIN EN 60204 must be adhered to during all work inside the machine
base.
Follow the instructions regarding residual voltages in Chapter "Operational Safety".
Comply with regulations on ESDs (see Chapter "Operational Safety").
During the work of service secure the machine conscientiously against other personnel and pre-
vent it from being turned back on without authorization, as described in the User Manual in the
chapter "Locking the Machine...".
There is additional, higher risk of accident when working with the SITEST program.
The SITEST program is only to be started by personnel who are authorized to do so.

1.2 General
The CAN Test Box is a tool for service technicians to test basic CAN bus functions at SIPLACE
machines. This CAN Test Box can be used on machines implementing a CAN bus with a baud
rate of 500 kBit or 1 MBit. Although the CAN Test Box can also be used for the slower CAN bus
(125kBit) on HS50/60 machines, the Error Frame Counter will not function in this case.
The following functions can be checked:
– Terminating resistors
– Recessive voltage levels
– Dominant voltage levels
– Power fail voltage level, CAN reset
– Error frames

1.3 CAN Bus Signal Assignment
Fig. 1.3 - 1 Signal assignment at the different connectors
– CAN_INT – not in use (+5V)
– Power Fail – triggers recording of operating data at the placement head (+5V)
– CAN RESET – not in use (+5V) (HS50/60 use the signal for the Tape cutter and component
table)
– CAN HIGH - 2,5 +/– 0,3 V recessive level (machine in idle mode)
– CAN LOW - 2,5 +/– 0,3 V recessive level (machine in idle mode)
– CAN GND - Can bus ground
– Vcc 24V - for nozzle changers - no longer available after the above mentioned conversions
– One wire - only applies to HF series, in the machine CAN bus cable
