PA1001A – 7/02

Wiring For RF Pickup Coil:

1. Connect a two conductor shielded cable from the pickup to Terminals 5 and 6. Connect the

shield to Terminal 4 (see Figure 1). NOTE: It is also preferable that the pickup coil be grounded

to the shield.

2. Connect a power source, which must be within 8-30 VDC, to Terminals 7 and 8. The Plus

voltage is connected to Terminal 8 and the Return to Terminal 7 (see Figure 1).

3. Connect the Pulse output wire to Terminal 3, and connect the Pulse common to Terminal 4 (see

Figure 1).

4. Set Jumper HD2 (see Figure 3) to the RF position.

5. Configure Jumper HD1 (see Figure 3) to the desired pulse output as follows:

Pulse Output Type

HD1 Jumper Configuration

Open Collector

JP2

Square Wave to Vin

JP1 and JP2

TTL/CMOS

JP1, JP2 and JP3

0-10 VDC Square Wave

JP1, JP2 and JP4

6. Install pickup (e.g. in meter) and provide power to PA1001A. Use a digital voltmeter set to DC

voltage and attach the positive lead to Terminal 6 and the common lead to Terminal 2. Adjust the

Carrier Adjustment (R2) (see Figure 3) to a reading of 3.00 VDC to fine-tune the pickup for air

gap, wall thickness, etc.

7. With power still supplied to PA1001A determine if pulse output is being generated in the absence

of motion. Adjust the RF Trigger (R24) (see Figure 3) clock wise until the false pulsation has

stopped. If pulsation continues when adjusted fully clock wise, check that all shields have been

properly terminated and grounded.
