3.5 Connection of Remote Interlock Connector
The MT9812B incorporates the remote interlock connector as one of the laser
equipment safety devices to be used when the light source is used. Unless the
terminal located in the back is in the state of short circuit, no light will be output
even if the optical output key on the front panel of the unit is switched ON.
It is advised to normally use the connector together with the short plug that comes
with the MT9812B.
To output the radiation from the light source into the experiment chamber as the
space light, use the connector by connecting it as shown below so that the light
will not escape when the chamber door (or window) is suddenly opened.

To the remote
interlock
connector
(1) Install a switch that is linked to the movements of the chamber door (or
window) so that when the door opens, the switch opens and when the door is
closed, the switch is short-circuited.
(2) Remove the short plug affixed to the remote interlock connector. (Make
sure not to lose the removed short plug.)
(3) Connect the remote interlock connection plug that comes with the
MT9812B and the switch as shown in the figure above, and affix the plug to
the remote interlock connector.
CAUTION
To connect the plug and switch to the remote interlock
connector, first turn the power source of the Device
OFF and pull out the power source cord from the power
receptacle. Connecting them while the MT9812B re-
mains ON may cause electric shock.
Moreover, do not connect items other than the short
plug or the remote interlock connection plug, and
short-circuit switch to the remote interlock connector
by all means. Failing to do so may cause a circuit fail-
ure or burnout.
When the remote interlock connector is in the state of open, and if the optical
output of the light source is turned on; the Opt. On key blinks to indicate that a
device of the safety measure is active.
