2 Safety Warnings
This device is intended to be used as part of a safety system which may be used to protect personnel
and equipment from possible injury, damage, or loss.
As such it must be installed and wired according to these instructions and tested by suitably qualified
persons. No attempt may be made to tamper with the parts, open them, or use them outside of the
parameters contained herein.
The units are only designed to be fixed to surfaces using their inbuilt fixing holes. They must not
come into contact with each other or any other moving part when in use. The parts should never be
subject to impact or mechanical strain.
Safety switches should never be defeated or bypassed. It is imperative that all steps are taken to
ensure that any spare actuators are made unavailable, such that they cannot be used to defeat the
switch or reduce the protection offered by the system in any way.

3 Concept
Lasermet Ultra LED Signs are intended to be wall mounted for which purpose several mounting
options exist. The sign is for indoor use only and should not be used in damp areas or places of high
humidity.
The sign is designed to give a long service life and has no user-replaceable parts inside.
The sign must be powered by a smoothed and regulated 24VDC supply capable of providing at least
0.7A. In order to minimise the effects of voltage loss in the wires the power supply should not be too
far from the sign and adequate wire thickness must be used in order that the voltage at the sign is
within the specified limits at the input to the sign when it is illuminated.
The 24V operating voltage provides enhanced safety within the sign and supply wiring compared to
a mains supply.
The sign has a dimming option which can be configured to reduce the brightness and power
consumption of the sign. This may be achieved either automatically according to the light falling on
an internal sensor, or by applying a separate brightness control voltage to the sign.
The message is almost invisible when the sign is switched off.
The sign may be used on its own or in conjunction with Lasermet’s interlock systems.
When the sign is used on its own, Lasermet offer a power supply and switch kit which enables easy
installation and operation.
Lasermet provides a full range of laser interlock equipment including control systems, interlock
switches, illuminated warning signs, laser shutters, door locks, external power supplies etc. which
can be connected to provide a complete laser interlock system. Full support, design and installation
is available from Lasermet, please contact us for any queries. Contact details are given at the end of
this manual.

4 Installation
The LED Sign is designed to be permanently attached to a wall or other fixed vertical surface. The
sign should be mounted in a convenient position for use and wiring, preferably sufficiently high up
the wall to render it relatively inaccessible without access equipment.
During installation, wired connections will need to be made to the sign and allowance should be
made for the installation of electrical conduit or trunking if required to make entry to the unit.
The sign may be directly screwed to the wall and four Ø5mm mounting holes are provided in the
back of the sign for the purpose. To access the fixing holes and electrical connections unscrew and
remove the plastic end caps and slide the front panel and graphics film sideways as required.
When sliding the front panel back into place, slide the flexible graphics film into position first
keeping it clear of the light sensor and indicator LED on the driver board. It is then easier to slide the
front panel across the top. It is most important that the components on the driver board are not
dislodged or bent as otherwise they will not align with the apertures in the graphics film. This will
impair the operation of the sign.
The preferred cable entry to the sign is via the Ø20mm hole provided in the rear top centre of the
sign. When directly wall-mounted, the use of buried cables provides the most aesthetically pleasing
appearance. Alternatively, 20mm surface-run plastic conduit may be brought to either end of the
sign, and a knockout is provided in the centre of each end cap for this purpose.
If there are two or more adjacent signs stacked vertically, Lasermet supply a joining strip which fills
the gaps between the signs and gives a more professional appearance. When mounting two or more
signs vertically, allow a 4mm gap between the signs for insertion of the joining strip.
Refer to Figure 1 for details of the fixing holes and cable entry. It is recommended that at least
150mm clearance is allowed at each side of the sign to permit removal of the end caps for
installation and wiring purposes.

Lasermet also supply a range of shallow surface trays which can accommodate multiple signs
arranged vertically. Each tray has a Ø20mm cable/conduit entry which must be located at the top.
Additional holes may be cut if required. The trays allow convenient hook-on mounting and electrical
connection to the signs.
To attach the signs to the wall tray, start with the bottommost sign, hang it on the hooks provided
on the wall tray and secure using two M4 X 12 screws in the bottom two fixing holes in the sign.
Make the wiring connections next, then lay a joining strip along the top of the first sign before
proceeding to fit the next one.

5 Wiring
The sign is powered by smooth regulated 24VDC. Normal one-way signs have one LED Driver circuit
board. Two-way signs and one-way signs with enhanced reliability have two LED Driver circuit
boards, each one operating half of the LEDs in the sign.
With the one-way enhanced reliability type it is possible to operate each driver from a separate
supply/circuit. In the event of loss of a supply, the sign can still illuminate at a lower brightness on
the other supply. For single-supply operation, it is necessary to wire the driver board supply
terminals in parallel. See Figure 6.
With two-way signs, either one driver or the other is powered to select the illumination colour and
message. Figure 8 shows a simple scheme to do this with a switch. Suitable controls are available
from Lasermet.
A three-way terminal block is provided on the driver board. Two terminals are used for the supply
connections. The third terminal may be used if desired for a remote dimming control voltage. The
connections are shown in Figure 4. Note that one-way signs have just one driver board.
It is preferable for the negative (0V) of the power supply to be connected to earth at the source. To
eliminate the potential for static electrical damage to the sign circuitry, the 0V terminal of each
driver board is connected to the casing of the sign through a 100Ω resistor. The sign contains no
hazardous voltages and it is not normally necessary to provide a dedicated earth connection for the
sign casing.
Where there are two driver boards and separate power sources are used for each driver board, the
negative wires of the two power sources should be connected together as shown in Figure 5.
A selector link is provided on the driver circuit board to choose the dimming method. If no dimming
function is required set the link to the ‘EXT/NONE’ position and make no connection to the DIM
terminal.
If using the internal sensor, set the link to ‘SENSOR’.
If using external control, set the link to ‘EXT/NONE’ and connect the external control voltage to the
DIM terminal.
The optional dimming control voltage is connected as shown in figure 7. The voltage should be in the
range 0 – 24V where increasing the voltage will increase the brightness. When using an external
dimming control voltage, the 0V of the control voltage must be connected to the 0V of the power
supply.
An external dimming control potentiometer may be used.

5.1 ‘Sign Good’ Indicators
Each driver board has an indicator which shows as a white spot at each end of the sign. One-way
signs having one driver board will show a spot at one end only. For two-way signs with two driver
boards, the presence of an indication at both ends confirms that both drivers are operating.
