Checklist
Before the initiation of the GuardShield Micro 400 the responsible
person should work through the following checklist.
Check prior to first initiation or after a changed machine setting (e.g.,
a rewiring):
1. The power supply is a 24V DC device, that must comply to all
applicable standards of the Machinery Directive 2006/42/EC,
and the product standard (IEC61496), for example 1606-XLP-
series. No connection to a conventional power supply.
2. Proper polarity of the power supply at the controller of the
GuardShield Micro 400.
3. The transmitter connection cable is properly connected to the
transmitter, the receiver connection cable is properly
connected to the receiver. All plugs are connected.
4. The OSSD outputs are not connected to +24V DC.
5. The connected switching elements (load) are not connected to
24V DC.
6. If two or more GuardShield Micro 400s are to be used, make
sure that each system is properly installed, in order to avoid
optical interference.
Switch the GuardShield Micro 400 on and check its function by
observing the following: two seconds after switching on, the
system starts to work properly if the protection field is free of
obstructions
Troubleshooting
With the help of two LEDs, system conditions and faults of the
GuardShield Micro 400 systems are indicated.
A red and a green LED are integrated in the end-cap connection
module of each profile (near the cable), which clearly signals the
status of the protective field. With the help of the LED display, system
conditions and faults of the GuardShield Micro 400 systems are
indicated.
Figure 16: Indicators
Table 7: LED meanings
The conditions signaled by the LEDs can also be obtained from
the status outputs of the connected MSR41 or MSR42 Series
safety control module (see user manual of the corresponding
control unit).
Red LED continuously shining:
Check the alignment if the LED of the GuardShield Micro 400 is
continuously red. With the help of the optical interface
(445L-AF6150) it is possible to display individual beam status at a
Laptop per USB interface.
Red LED blinking (lock-out condition):
If the red LED of the GuardShield Micro 400 is blinking, the
following conditions can cause the fault:
1. Inadequate supply voltage to the MSR41 or MSR42 safety
controller.
2. Transmitter and/or receiver cables not correctly plugged into
the MSR41 or MSR42 controller.
3. Transmitter and receiver light curtains are connected to the
incorrect locations in the controller (transmitter plugged into
receiver connection).
4. Incorrect assembly in case of cascaded systems (transmitter
and receiver mixed).
5. Cable connector makes poor contact.
6. Error in the EDM feedback channel at the safety control (only in
case of EDM).
7. Short circuit at the OSSD outputs.
8. Foreign light source affecting the receiving unit.
9. Blanking configured and wrong light curtain length or
resolution connected (only in case of blanking).
ATTENTION
Prior to first powering up or after a changed
machine setting, the responsible person shall
review the following checklist.
