Interlock connector
Shorting wire 2
Shorting wire 1
Connector no.
• When the length of the wiring is less than 5 m (approximate)
Remove shorting wire 1 or shorting wire 2 and connect the external contacts (switch) to the projector interlock terminal (
or
and
) by cable.
- The projector operates normally when the contacts are closed and the system shuts off when the contacts are open.
- A power supply external from the projector is not necessary.
- A maximum of 2 sets of external contacts can be connected. If you are only using a single set of external contacts,
connecting the shorting wire to the interlock terminal you are not using.
- The minimum rating required of the external contacts is 5mA.
• When the length of the wiring is at least 5 m (approximate)
Remove shorting wire 1 and shorting wire 2 and connect the external device to the projector interlock terminals (
not use
and
).
- Connect terminal
- The projector operates normally when a voltage in the range of DC5 to 16V is applied between terminals
the system shuts off when the voltage is 0V.
- The minimum rated current required of the external device varies depending on the voltage applied between the terminals
by the external device.
- When feeding the cable out from the projector, feed it so that it passes through the hole on the front face of the projector.
