2.0 SCOPE

The information contained within this manual covers the AZL (Azmith and Elevation Read-Out Meter).

3.0 DESCRIPTION

The AZL is used to provide a visual read-out (in degrees) of the mechanical position of DC based pan/tilts such as Pelco's P/T1250DC/PP equipped with position feedback pots.

The AZL consists of two easily read Simpson meters mounted on the front panel of the unit along with the power switch and power on indicator.

The fourteen pin CPC connector on the back panel of the unit provides the necessary wiring interface for the unit. This wiring interface is usually integrated with controller wiring at the point where the cabling connection is made to the P/T (reference Figure 1's simplified diagram). The rest of the back panel consists of installation set-up pots for initial meter calibration. A power input cord, input line fuse and a convenient power outlet plug round out the back-panel connections.

4.0 INSTALLATION

Installation consists of installing the interconnecting cable between the AZL and the P/T in use and initial adjustment of the meters for operation.

4.1 CONNECTOR INSTALLATION

Reference Figure 2 and Figure 3. Before connecting the wiring, set the meter module “full scale” adjustment pots (these are the 5K pots) on the back of the

AZL unit at the full CW (clockwise) position and set the “center scale” adjustment potentiometers (these are the 1K pots) on the back of the AZL unit at approximately center.

Now, reference the AZL wiring diagram in Figure 2.

The wiring for connector pins 2 and 9 go to the “pan feedback” and “tilt feedback lines”, respectively, on the

P/T, which, in the case of a PT1250DC/PP, share corresponding numbered pinouts. For the rest of the AZL wiring, we have pin 10 - which is AZL common - that is wired to feedback common (pin 10) on the P/T and pin 11 (AZL B

+

, +5VDC) that is wired to “feedback

B

+

” on the P/T. We assume, of course, that any other additional wiring needed for the system in question has already been done or is also being done at this time

(controller wiring, for example). Once the wiring interface is in place, the next thing to consider is AZL meter adjustment.

4.2 AZL METER ADJUSTMENT

4.2.1 Preliminary Remarks

Figure 3 is a diagram of the internal wiring (minus power supplies, etc.) of that part of the AZL unit related to meter adjustment. Shown there are the full and center scale pots for pan and tilt on the AZL as they would be wired to the respective position feedback pots on a Pelco

P/T1250DC/PP. Interconnections between the two units are shown as circled numbers. As shipped, the pan/tilt unit is mechanically configured to be resting at horizontal in the tilt position and at approximately 180 the pan position.

°

in

The meter adjustment procedure for both the pan and tilt meters follows the same method. Assuming you have already performed the connector and pot adjustments indicated in Section 4.1, the step-by-step procedure for meter adjustment is as follows:

4 Pelco Manual C521M (6/95)

4.2.2 Pan Meter Adjustment

1.

Turn on the power switch. There should be a slight noticeable change in the meter reading.

2.

Activate the PAN LEFT switch and observe the pan meter reading. The AZL pan meter readout should approach “0” as the unit rotates. The unit will stop at the extreme left position. Note the meter reading. For our example, let's assume the reading is 60

°

(see Fig. 5a).

3.

Note the meter reading and activate the PAN

RIGHT switch until the unit reaches the extreme right position. Note the meter reading. For our example, lets assume the reading is 330

°

(see Fig.

5b).

4.

These two meter readings define the “deflection range” of the meter (in our case 330

°

- 60

°

= 270

°

, see Fig. 5c) and mirrors mechanical pan movement of the P/T between its extremes. This “range” must now be shifted (in our case, to the left) by adjusting the “center scale potentiometer” (PAN 1K pot, see Fig. 3) on the AZL back-panel to obtain a balanced meter deflection at both ends. The simplest method of calculating what the balanced meter deflection should be at both ends is to subtract the

“deflection range” from the total meter range and divide by 2.

In our example:

360

°

- 270

°

/ 2 = 90

°

/ 2 = 45

°

In other words, the entire range should be shifted to the left enough so that the difference between the deflection range reading made at the PAN LEFT operation and 0

°

and the difference between the

PAN RIGHT operation and 360

°

are equal and have a value of 45

°

. In our example, then, we require the PAN RIGHT meter reading to be (360

°

- 45

°

), or 315

°

. The current meter reading is at 330

°

, so you must now adjust the “center scale pot” (PAN

1K pot, see Fig. 3) until you obtain a meter reading of 315

°

. This shifts or “rotates” the entire deflection range for a balanced meter deflection at both ends as indicated in Figure 5d.

5.

Now adjust the “full scale potentiometer” (PAN

5K Pot, see Fig. 3) on the back of the AZL unit to obtain a reading of 360

°

.

6.

Finally, activate the PAN LEFT switch until the unit reaches the extreme left position. Verify the meter reading to be “0” degrees. Make minor adjustments as necessary.

4.2.3 Tilt Meter Adjustment

Use the same methods for the tilt adjustment as those just employed for the pan meter adjustment.

Once the procedure is complete, the extreme electrical rotation limits can be reset down from the factory maximum settings.

5.0 OPERATION

When power is applied to the unit the power LED on the front panel lights.

The pan and tilt meters on the front of the AZL unit will give a direct, visual, real-time readout, in degrees, of the physical orientation of the pan/tilt to which it has been electrically connected.
