Setup Procedure
The current sensing component is part of a twisted pair cable, and includes a mono-type phone plug, which plugs into the Power
Sensor enclosure.
Figure 4. Current Sensor and cable (is also item 5 in Figure 5)
The Power Sensor gets its operating power from, and also sends a signal to the System 5. It requires a one-to-one cable, as shown on the previous page. If the cable has not already made, use the instructions on the previous page for making a cable.
__ The sensitivity adjustment range is such that the LED (d) will light without having the sensor connected, or near a current source.
1. Because there will be +12 volts on the tip of the connector, first plug the 3.5 mm cable to the Power Sensor (b), and then to the
System 5. The Power LED (a) will light. (If not, check the power cable and connections.)
___ DO NOT connect the current sensor cable (item 5) yet.
2. Turn the adjustment knob (e) clockwise until sensor LED (d) is brightly lit.
3. Slowly turn knob (e) counterclockwise as sensor
LED (d) dims. Stop when sensor LED (d) just goes
OUT.
4. Turn projector power ON.
5. Plug sensor cable into jack (c) and move sensor (f) against projector’s power cord (g).
Find a position where sensor LED (d) is brightly lit.
___ Be sure that there are no other power cords close by.
6. Use a tie-wrap to attach the sensor
(f) to power cord (g) at that position.
7. Turn the projector OFF, the sensor
LED (d) should go out.
8. Repeat steps if necessary.
9. Verify the operation by turning the projector on and off.

Installation and Operation

The Display Power Sensor is one of the options available for the
System 5 pictured near the bottom of Figure 1. When properly installed, the sensor will “tell” the System 5cr when the projector is turned ON. If the System 5 sends a Display Power On command, for example, and the sensor does not detect the power coming on, the System 5 can send the command again (up to three times).

The sensing device is designed to attach to the power cord of the projector being used with the
System 5. Because different projectors use different amounts of power, the Power Sensor must be adjusted for the projector in each installation.
Use these illustrated procedures for making the cable and connecting the sensor to the System 5, as well as for adjusting the sensitivity. The components on the control panel shown above have the following functions: a. Power LED lights when receiving power from the System 5.
b. A 3.5 mm stereo mini jack, (tip/ring/sleeve) to System 5.
c. A 2.5 mm jack with two contacts for the current sensor.
d. A sensor LED that lights when the unit senses current (power).
e. A knob for adjusting the sensitivity level. See back page.
Velcro on the top of the enclosure allows it to be mounted in an appropriate place. The power sensor must be installed close to the projector.

Installation and Operation
Extron provides the 3.5 mm connectors with the Power
Sensor, however a cable will have to be made to fit the installation requirements.
Use the information on this page when making the cable and connecting it. Figure 2 shows how to wire a 3.5 mm connector for the Power
Sensor voltage, signal and ground, as used between the
System 5 and the Power
Sensor unit. A finished cable is shown at the bottom of
Figure 2. Connect both ends of the cable the same, for a one-to-one configuration.

Figure 2. Solder wires to tip, ring, and sleeve.
___ When finished, either end of the cable can plug to either device.
However, because there will be +12 volts on the tip (from the System 5) it is best to plug the cable to the Power Sensor first, and then to the
System 5.
Figure 3 shows how the cable connects between the System 5 jack (rear panel) and the Power
Sensor. The contact assignments are:
Tip = +12 volts
Ring = Signal
Sleeve = Ground
See the next page for connecting and adjusting the current sensor device.
