A switched shutter power supply is required. Connect pin 1 to the +ve side of the supply and pin 2 to
0 Volts. The shutter can be opened and closed using its buttons when the supply is present. When
the supply is removed, the shutter closes.
If using remote control with a switched supply, connect the switched to pins 1 and 3 and –
to pin 2. The shutter will open immediately the supply is turned on.
If using remote pushbuttons to control the shutter use a normally closed button in series with the
supply for the ‘Close’ function, and a normally open pushbutton between pins 1 and 3 for the ‘Open’
pushbutton. Both switches need only switch for approximately 0.25 s to close or open the shutter.
The existing pushbuttons will still work as normal. A remote switching unit with indication LEDs (part
number LS-RS) is available from Lasermet. While the switched supply is present, the shutter status is
indicated on LEDs on the unit and is available as an indication contact if the optional interlock option
is ordered. Contact Lasermet for other control methods.

Operation
When the power supply to pin 1 of the shutter comes on, the middle yellow LED will light. The green
LED will also light indicating that the shutter is closed. Pressing the green button momentarily will
open the shutter. The Orange LED will light indicating that the shutter is open, and the beam is
exposed. To manually close the shutter, press the red button. Loss of power to the shutter, such as
when a door interlock switch trips the interlocked power supply, will also cause it to close.
Status Outputs – pins 5 and 6
When the shutter is open, the power supply voltage is output on connector pin 5. When the shutter
is closed, the power supply voltage is output on connector pin 6. The maximum load that may be
placed on these outputs is 100mA non-inductive. If connecting them to an inductive load such as a
relay coil, a diode should be fitted across the load with the anode to 0V.
Optional Interlock – pins 7, 8 and 9
These connections are reserved for an optional internal electrical interlock board (part no: LS-10-IB)
which provides two volt-free contacts indicating the state of the shutter. This factory-fitted option
may be specified at time of ordering.
