Original instructions
Cascading segment’s DIP switch settings
There are a few operating modes that can not be configured in the
middle and end segments of a cascading GuardShield system. The
following Operating modes if configured will cause the light curtain to
fault;
• EDM (External Device Monitoring)
• Start and Restart Interlock
Power must be cycled and the segment pair must be re-taught to
deactivate the mode.
Teach Function
Procedure:
Note: The doors on the transmitter and receiver must be closed
for the GuardShield to operate.
Troubleshooting Guide
The light curtain carries out an internal self-test after startup. If an
error occurs, an appropriate signal combination is sent through the
LEDs to the transmitter and receiver.
Step 1
Open cover of the end cap (LED blinks: Receiver is red
LED, Transmitter is amber LED).
Step 2
Select the desired switch setting.
Step 3
Press and hold the Teach button. The yellow LED
flashes at 10 Hz (10x per second).
Step 4
The yellow LED will stop blinking while the button is
depressed. After the yellow stops flashing, release the
teach button within 2 seconds.
• After 3 flashes of the yellow LED the function is
activated.
Step 5
Close and secure the cover.
Configuring EDM in a middle or end segment
will cause an EDM fault in that configured
segment even if EDM is also configured and
functioning in the Host segment. Interruption of
the middle or end segment which has EDM also
configured will cause the middle or end
segment to go to a lock out condition that can
not be reset without cycling power and
reconfiguring the middle or end segment
without the non allowed configuration.
Configuring Start or Restart Interlock in the
middle or end segment will cause a fault in the
middle or end segment which has that
Operating mode configured. The LED indication
will show a “Waiting for reset” fault which can
not be reset even if the Host segment is also
configured for Start or Restart Interlock. Due to
the lack of an internal reset line in the middle or
end segment it will not be possible to reset the
middle or end segment before resetting the
Host segment.
IMPORTANT
If the GuardShield teach procedure is not
properly completed, the unit will remain in the
previous operating mode.
IMPORTANT
Condition
No. Error Description Action
8
Internal fault, receiver • Check configuration of
transmitter and receiver
• Replace receiver
9
Internal fault, transmitter • Check configuration of
transmitter and receiver
• Check protective field
transmitter/receiver
• Check connections
transmitter/receiver
• Exchange transmitter
10
External fault • Check connections of
OSSD outputs for short
circuit against +24V DC and
GND (cable, connected
devices)
• Exchange receiver
11
External fault (MPCE error)
The function Relay monitoring is activated
and after clearing the OSSD the input Relay
monitoring does not recognize a change of
state. • Check connection Relay
monitoring
• Check connected relay for
closed contact (if OSSD
ON—input Relay monitoring
must have GND level, if
OSSD OFF—input Relay
monitoring must have +24V)
• Switch on only after
POWER OFF/ON
12
Configuration mode (Receiver) • Cover for DIP switch setting
at the receiver is open
13
Configuration mode (Transmitter) • Cover for DIP switch setting
at transmitter is open
Once the teach function is completed and the
door secured, verify that the operating mode
has changed to the intended mode.
