Introduction
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 it’s own or in conjunction with Lasermet’s access/interlock
systems.
When the sign is used on it’s own, Lasermet offer a power supply and switch kit
which enables easy installation and operation.
Lasermet provides a full range of laser/laboratory interlock equipment including
control systems, interlock switches, laser shutters, door locks, access signs, external
power supplies etc. which can be connected to provide a complete 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.

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.
IMPORTANT: 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.
Figures 2 and 3 show the arrangements when using the wall trays.

Figure 3: Mounting Arrangements for 4-way Wall Tray.
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.

Wiring
The sign is powered by smooth regulated 24VDC. Normal one-way signs have one
Driver circuit board. Two-way signs and one-way signs with enhanced reliability have
two Driver circuit boards, each one operating half of the LED’s in the sign.
With the one-way enhanced reliability type it is possible to operate each driver from a
separate supply/circuit so that 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 standard
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
100 ohm 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.

‘Sign Good’ Indicators
Each Driver board has an indicator which shows as a white spot at each end of the
sign. Standard signs having one driver board will show a spot at one end only. For
dual-driver types the presence of an indication at both ends confirms that both
drivers are operating.
