Beam Shutters
The ICS-6 may operate one or more beam shutters and one or more laser interlocks. For permanent
fixed installations these may be directly wired to the ICS-6. Where there is any possibility of the
equipment being changed or moved it is often most convenient to be able to unplug the equipment.
Lasermet provide a range of small distribution boxes which allow for convenient positioning of wall
or surface-mounted plugs for laser interlocks and sockets for shutters. The boxes are available with
different combinations of plugs and sockets.
Most lasers only have a single channel interlock input which can present problems if the safety
system has to comply with ISO 13849 performance level ‘e’ since two methods of control are usually
required. Some lasers have internal beam shutters which may be controlled by the ICS-6. If the laser
has two means of disabling e.g. interlock and internal shutter it is recommended that both are used.
Otherwise it may be necessary to consider having an external shutter in addition to the laser’s own
interlock if a high safety integrity is required.
Lasermet’s beam shutters are supplied with suitable leads to plug into the distribution boxes. Open-
ended leads are provided for laser interlocks allowing the customer to fit the correct plug for the
laser.
Laser Shutter Supply
(12 VDC 0.8 A maximum or 24 VDC, 3 A maximum)
The ICS-6 has a built-in DC supply for operating laser shutters and is able to provide both continuous
and switched supplies using one of the Interlock Operator outputs. Several shutters of the same
type may all be powered from one Interlock Operator contact, please contact Lasermet for details if
required.
Note. The selected Interlock Operator used for switching shutters must not be used for any other
purpose.
If your shutter power requirements exceed 0.8 A at 12V or 3A at 24VDC, or if there is additional
equipment such as low voltage warning signs or door locks powered by the ICS-6, the ICS-6 internal
power supply may be insufficient. The maximum total load that may be placed on the internal
power supply is 4A, which includes any other equipment being run from the 24V supply, such as
door locks, signs etc.
In such cases the shutter may be run from a separate power supply. The mains input of this power
supply is connected to the L OUT and N OUT terminals of the mains terminal block J9. The PSU
output is fed through the interlock operator terminals to operate the shutter. Please contact
Lasermet for suitable power supplies and assistance.
