8.7 Safety control
Safety control of output voltages is provided by unit CSB (Contactor based Safety Breaker), which
consists of two functional units:
1. Circuit Safety Contact Breaker Unit
2. Pre/discharge board –A2 for monitoring and suppressing the load current of the main axes.
The unit provides functionality for:
●
Safety control of output voltages 300/160/42 and 24V
●
Pre-charge external capacitors (300 and 160V lines) within 1s to avoid unauthorized current
loads on connection when switching on output voltages
●
Discharge external capacitors (300 and 160V lines) within 1s to a value below 60V when
switching off output voltages
●
State signaling to Fuse Diagnostic unit located at FD.A1
●
Power enabled signal to MGCU, MHCU and conveyor units
Unit is made of a baseplate that carries contactors and wiring covered by a PCB carrying all
connectors and interfacing.
CAUTION
In event of faulty unit the complete unit needs to be exchanged.
DANGER
Do not open the unit. The unit is completely housed to protect the user from dangerous
voltages. The complete assembly is available as a spare part.
NOTICE
Shuttle safety loop
The safety loop is not a hardware connected to the machine.
The safety loop is controlled by the machine software via CAN bus.

8.8 Analysis - Common Error List
Error Possible Cause Action
No reaction after
START pressed
Duration of pressing and release of
START button
●
Press longer than 200 ms and
shorter than 1500 ms.
START should be accepted on
pushbutton release.
Safety loop closed?
●
Check if both channels of
safety loop show closed
condition
SW_CTRL_ON output of IO
missing?
●
Check: (X29.A6) should be
HIGH if START is pressed
●
Check IO wiring.
●
Check IO output.
●
Check START button wiring.
If output is missing:
●
Replace IO unit
●
Fix START button wiring.
Connection to PCB FD.A1
established?
●
Check connectors X24A and
X24B at FD.A1 and at PCB
CSB
●
Place connectors firm in
position.
Ground connection of PCB CSB
missing?
●
Connect terminal lug to
Ground terminal of CSB.
Supply voltage of CSB missing?
●
Check fuses F12 and F13.
●
Replace fuses F12 and F13, if
needed.
Signal PCC-POWER-OK (X24B.5
at PCB,LED at K5)
If voltage reading > 22V or Power
OK LED of K5 is on→ internal
defect of CSB:
●
Replace unit
24V Measure input voltage
(X24B.3)
If voltage reading > 22V → internal
defect of CSB:
●
Replace unit
Power connectors of CAP and CSB Connectors should be firm in
position.
 DANGER!
If you check connectors
mind the dangerous
voltage!

8.8 Analysis - Common Error List
Technical Training SIPLACE TX-Series 10/2016 211
Error Possible Cause Action
Short reaction of CSB
after START pressed
●
Check precharge current at
300 V DC link voltage
If there is no precharge current
(max 10A):
●
Check GND connection of
CSB
Ground connection of PCB CSB
missing?
●
Connect terminal lug to
Ground terminal of CSB.
If there is GND connection
established:
→ internal defect of CSB;
●
Replace unit
Overload or short circuit at 160 V
DC link output?
●
Remove X24B and try to start.
If Start is working now fix short
circuit conditions at 160V DC link
branch
Overload or short circuit at 300 V
DC link voltage?
●
Remove X21 and X22 and try
to start.
If Start is working now fix short
circuit conditions at 300V DC link
branch
Machine is passing
reference run but stops
at beginning the of
production run
MGCU Error Message: Under-
voltage error at DC link voltage?
●
Check capacitor value of CAP
unit (service screen of dia-
gnostic functions) has to be >
30 mF
If Capacitor value < 30 mF:
●
Replace capacitor unit
●
Check QT40.999 error
messages at service screen
If QT40 error is shown:
●
Replace QT40 unit.
Service screen QT40 unit
●
Check indicator lights at
QT40-999:
Green light (>220V) should be on
during reference run
red light should be on temporary
during gantry acceleration period
DC 42V-S is missing
(Conveyor supply)
Fuse does not work?
Connector X24A (both PCB’s!)
properly connected?
●
Check supply voltage at
FD.A1, F16
Fuse blown or broken?
●
Replace fuse
●
Place connector firm into
place
If error still occurs
→ internal defect of CS:
●
Replace unit
