GuardShield Safe 4 Operation Manual
5.2.3. Adjustment Procedure without ILAS
1. Mount the transmitter and the receiver with
the adjustable mounting brackets. Make
sure that the longitudinal axis of both are
oriented parallel. A spirit level might help to
find the correct position.
2. Take care that the receiver and transmitter
are oriented in the same direction. This
means, the controllers of the transmitter
and receiver have to be at the same end of
the protective field.
It is not allowed to mount GuardShield Safe
4 systems turned by 180° (Figure 10)
Figure 10: Layout of the transmitter / receiver
3. After aligning the longitudinal axis of transmitter
and receiver, rotate the receiver around the
longitudinal axis to find the receiving angle.
During rotation, the receiving angle is shown
when the green LED of the receiver controller is
on.
4. Adjust the receiver to the centre point of the
operating angle, and tighten.
5. After aligning the receiver rotate the transmitter
to find the emitting angle. During rotation, the
emitting angle is shown when the green LED of
the transmitter controller is on.
6. Adjust the transmitter to the centre point of the
operating angle, and tighten.
7. Control the operation of the GuardShield Safe
4 light curtain by using the test rod (Figure
12). Introducing the test rod into the protective
field at any position must lead to a protective
field interruption (shining of the red LED on the
receiver).
When mounting Perimeter Systems adjust the heights
according to the recommendations in the relevant
standard, i.e, EN 999, ANSI/RIA 15.06 etc.

5.2.4. Adjustment Procedure with ILAS
1. Mount the transmitter and the receiver with the
adjustable mounting brackets. Look for that the
longitudinal axis of both are oriented parallel.
Take care that receiver and transmitter are
oriented in the same direction. This means, the
controllers of transmitter and receiver have to be
at the same end of the protective field. It is not
allowed to mount GuardShield Safe 4 systems
turned by 180° (Figure 10).
2. The ILAS is activated by touching the hand
symbol at the transmitter and at the
receiver.
3. Adjust the transmitter and receiver in a way
that both laser points hit the laser target on the
opposite unit. Small deviations are harmless as
long as they are within the aperture angle.
4. Tighten all screws firmly.
5. Switch the ILAS off when aligned.
6. Control the operation of the light curtain by using
the test rod (Figure 12). Introducing the test rod
into the protective field at any position must lead
to a protective field interruption (shining of the
red LED on the receiver).
5.2.5. Remarks to ILAS
Due to dimensional tolerances the red ILAS light spot
deflects from the target center when the light curtain
is aligned optimally in the center of the operating
range. The optimal operating point can be found after
alignment with ILAS (chapter 5.2.4) when moving the
axis in X- (left, right) and Z- (up, down) direction. The
optimal operating point is in the middle of the two end
points, where the receiver output switches from active
to inactive condition.
