Figure B shows important light curtain parameters. These parameters are shown as
C, M, K and R.
C - Light curtain column mounting centres. Use 6mm bolt for fixing
M -Length of the light curtain enclosures excluding end-caps
K - Detection height
R - Scanning range of the light curtain
Detection zone width (K) –Must be of a suitable height for each application to
prevent personnel access to the danger area, either over, under or around the light
curtains detection zone.
Range (R) –Ensure the particular light curtain specification is capable of satisfying
the range requirement for the application.
Fig. E also shows the connection points for the A cable between the transmitter (Tx)
and the receiver (Rx), B Cable connection and mute input connections.
To ensure correct operation of the system cable lengths as stated should not be
exceeded: A cable = 55 metres. B cable = 50 metres.

Figure C shows the use of a Perimeter light curtain and mirror arrangement.
A detailed explanation of the use of mirrors and safety light curtains in machine safety
applications can be found in Appendix 1.
If utilising mirrors to deflect the light curtain ensure the mirror length is 100mm longer
than the light curtain detection height and mounted centrally to the zone. To ensure
reliable operation the light curtain deflection angle from the mirror must not be less
than 40 degrees or greater than 100 degrees.
Figure D shows 8000 Series light curtain end-bracket dimensions. Use M6 bolts
for the mounting brackets.

CD246/080610 INSTALLATION SHEET EXPLAINED
When installing a Smartscan 8000 Series light curtain your attention is drawn to the
following: (Figure F)
3. Ensure the mounting position of the light curtain in respect to the nearest danger
point meets the requirements of European Standard EN ISO 13855.
4. Ensure the light curtain transmitter and receiver units are mounted accurately in
line with each other and are both perpendicular and parallel to each other within the
parameters shown for each axis.
1. Consider reflective surfaces that
may give rise to optically ‘short
circuiting’ the direct path of the light
curtains as shown. To ensure the
light curtain is mounted far enough
away from reflective surfaces use
the formulae provided to calculate
the minimum dimension between
the light curtain and reflective
surface.
X = minimum distance (mm) between
reflective surface and light curtain.
2. To prevent intermittent tripping of
the light curtain ensure extraneous
infra-red energy between 800 and
1000 nanometres is not directed
towards the Perspex window of the
receiver unit (RX). Extraneous
sources would include infra-red
sensors, infra-red remote controls
or scanning systems.

Figure I shows the range of 8000 Series light curtains and cables. It describes
model codes, number of beams, aluminium extrusion length (M), detection zone width
(K), light curtain mounting centres (C) weight in (Kg) of the transmitter (Tx) and
receiver (Rx) columns and the maximum scanning range (R).
For example, model number 083E903 will provide a 900mm high detection zone, 3
beam light curtain with standard software option. Model number 183E903 will provide
the following, 900mm high detection zone, 3 beam light curtain with a blue integrated
mute beacon and standard software option.

Figure L –Activate control
The ACTIVATE control has two functions.
1) Restart. At power-up or, following a tripped condition, the activate switch is
used to restart (reset) the output relays to an ON state. The switch must be
activated and released to enable a restart condition.
2) Override. If the safety system trips when a pallet load is interrupting the
beams in the light curtain the safety system cannot be restarted. To
overcome this condition the activate switch can be used to establish the
light curtain output relays to an ON state for a period of 3 minutes. This
period is normally enough time for an operator to restart the machine and
remove the pallet load from the detection field of the light curtain. For the
output relays to remain energised the activate switch, normally ‘spring
return’, must be held in the ‘closed’ position during the entire 3 minute
mute override period.
The activate input requires a 24V DC source voltage.

Figure M -Test and Maintenance
The Transmitter (Tx) and Receiver (Rx) windows should be cleaned regularly as
indicated on the Installation Sheet.
Dirt build up on the windows may lead to intermittent tripping or a totally blocked
condition of the light curtain. Clear adhesive tape may be applied to the windows of
curtains in dirty or abrasive conditions. Renew the clear adhesive tape periodically.
Clean the windows with a clean damp cloth using a mild detergent. Never use
abrasive, corrosive cleaners or spray detergents.
Power-up the light curtain and
activate the output switching
circuits to an ON condition.
Insert a test piece of appropriate
size into the top light beam,
150mm from the transmitter unit.
At this point the output switches
will turn OFF as the test piece
totally obscures the beam.
Repeat this process through each
of the beams in the light curtain.
Ensure that while the test piece
is obscuring each beam the
output switches are OFF.

Figure O outlines the procedure for returning a Smartscan product.
If a fault occurs that cannot be resolved or the equipment is damaged return the
system to the nearest Smartscan distributor or Smartscan Ltd. Indicate the nature of
the fault and the symptoms displayed on the form provided.
Returned guards must be matching serial number pairs. This is to ensure that
the Service department can carry out a full and proper inspection of the
returned light curtain system.

Figure R –shows the standard timer software (E) used in the 8000 Series for pallet
entry/exit applications. The software version is shown against the corresponding part
number. E.g. 083E903. The timers used in both cross-beam and parallel beam
modes are shown below. Please refer to the separate document on the 8000 Series
muting modules for further information.
Cross Beam
T1 (Mute 1 and Mute 2 Disparity Time) = Maximum time allowed between
activation of signals mute 1 (M1) and mute 2 (M2) prior to the pallet entering the light
curtain.
T2 (Mute Time Out Period) = A maximum pre-determined time the light curtain will
remain in a muted condition. Following this timed period, if the pallet is still
interrupting the mute beams or light curtain the OSSD’s will de-energise thus
initiating a stop condition. Providing the pallet clears the light curtain before the
maximum time T2 is exceeded then automatic transfer of the pallet will continue.
T3 (Mute Off Delay Time) = A predetermined time that the light curtain will remain in
a muted condition following de-activation of one or both of the mute signals.
Note: It is assumed that the Mute enable signal is energised during the entire pallet
transfer process.
Software version example
The standard 8000 Series is supplied with ‘E’ version software, for example 083E903
This provides the following functions for cross-beam,
T1 = 2.5 Sec T2 = 15 min T3 = 2.5 Sec.

SMARTSCAN 8000 SERIES LIGHT CURTAIN 18
CD246/080610 INSTALLATION SHEET EXPLAINED
Parallel Beam control timers
T1 (Pallet Transfer Time) = Minimum to maximum time during the pallet transfer
between, activation of mute beam 1 (M1) and the light curtain. Then T1 is repeated
again for pallet transfer between the light curtain and mute beam 2 (M2).
T2 (Mute Time Out Period) = A maximum pre-determined time the light curtain will
remain in a muted condition. Following this timed period, if the pallet is still
interrupting the mute beams (M1 and M2) and the light curtain then the OSSD’s will
de-energise thus initiating a stop condition. Providing the pallet clears the mute
beams and the light curtain before the maximum time T2 is exceeded then automatic
transfer of the pallet will continue.
T3 (Mute Off Delay Time) = A predetermined time that the light curtain will remain in
a muted condition following de-activation of one or both of the mute signals.
Note: It is assumed that the Mute enable signal is energised during the entire pallet
transfer process.
Software version example
The standard 8000 Series is supplied with ‘E’ version software, for example 083E903
This provides the following functions for parallel beam,
T1 = 0.15 -7.0 Sec T2 = 15 min T3 = 2.5 Sec.

Mirrors
Reflector mirrors can be provided enabling two or three sides of a machine to be
safeguarded with, what is effectively a single light curtain.
When mirrors are employed it is essential that the mounting of the transmitter unit,
receiver unit and mirrors themselves are sufficiently rigid. Alignment becomes
increasingly critical as the range and number of mirrors increase. Mirrors cause a
reduction in optical efficiency, reducing the effective range. A guide to the
practicality of using mirrors is given below.

Note: The angle of the light curtain striking the reflective surface must be within
defined limits.
