Figure 4. AZL Wiring Interface to P/T
4.2AZL 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 hori- zontal in the tilt position and at approximately 180° in the pan position.
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
