IRIS MODEL P522 APPLICATION MANUAL

A source impedance resistor is required when using the P522 module with a S550 viewing head. This resistor should be 330 ohm (factory installed) for viewing head cable runs up to 500 feet, and it should be 150 ohm for cable runs 500 feet to 1000 feet. The resistor should be installed across the SC and SIG GND terminals. A 1/4 watt resistor is suitable.

Originally, specifications of the IRIS Model 500 in- structed that a five-conductor cable be used, with one wire shielded. However, the standard is now a four-conductor cable, with one wire shielded. In this case, the shield is used as the signal ground wire that goes to terminal SIG GND on the P522 and to pin 3 on the viewing head plug. The shield should be a braided type for this application –do not use a foil type shield– so that a solid signal ground is main- tained. This signal ground shield is also the self- checking circuit return path. Refer to Figures 2 and 3 for wiring details.

Connections of the IRIS cable to the viewing head plug should be performed as follows:

After removing the plug from its packaging, take the cable entry nut out of its housing. Remove rubber grommet and flat sealing washer. With a pair of long- nosed pliers, remove the center ring only of the rub- ber grommet.

1.Strip two inches of the cable’s outer cover from the cable, removing any cellophane wrap or filler material, and strip the in- sulation from the shielded wire (if insu- lated over shield) a full two inches, to expose shield.

2.Slide the shield back until a bulge devel- ops close to where the wire exits the cable’s outer covering.

3.Carefully spread a few strands of the shield at the bulge –making sure not to break any strands– to create an opening, and slip wire out of shield through opening.

4.Carefully return shield to original shape and length by pulling gently, then cover with plastic shrink tubing to prevent shorts.

5.Slide nut (with threads toward the cable end), the washer and the grommet onto the cable approximately six inches.

6.Slip the cable through the bottom open- ing of the connector, making sure that the cable’s outer jacket is secure under the cable clamp, and tighten the two screws on the cable clamp.

7.Reassemble the grommet, flat washer and cable entry nut, and tighten.

8.Before wiring to connector, strip each wire 3/8 inch, as shown in assembly dia- gram, Figure 3.

9.Proceed to wire the connector. Refer to Figure 2 for terminal locations.

–Connect the viewing head signal wire WHT (the shielded wire) to terminal No. 1 by inserting it into the opening, then tightening the retaining screw.

–Connect the shutter drive signal wire BLK to terminal No. 2.

–Connect the signal ground shield from the WHT wire to terminal No. 3 with shrink tubing.

–Connect the 24 VDC power wire RED to terminal No. 4.

–Connect the power ground wire GRN to terminal No. 5.

–Assemble the back of the plug and insert jackscrew through the plug assembly.

The cable wiring at the other end going to the signal processor is easier. The cable should be prepared in a similar way to the plug end – particularly the shield from the WHT wire. Make sure the shield doesn’t touch the other terminals.

Careful consideration should be given to the power supply used for the P522. 26 VDC is used to back bias the “steering” rectifier, as shown in Figure 1, to
