8. Align the receiver to the transmitter image

following Steps 1 through 7.

9. Ensure the receiver's green LED is flashing,

indicating the preliminary alignment is complete.

10. If the receiver’s green LED is not flashing, repeat

Steps 1 through 9 for the receiver.

6.2 Sensitivity Adjustment

1. Select the appropriate sensitivity setting based on

the distance between the transmitter and receiver.

(refer to Table 3 which lists distances including

some settings that overlap). Select a lower setting

for a more sensitive detection or select a higher

setting for better immunity to false alarms.

* Do not use positions 8 and 9. They are not valid.

2. Set the receiver’s Sensitivity switch to your selected

setting. The Sensitivity switch is located to the right

of the optical module. The indicator, or pointer

marking, runs along the side of the switches' shaft

(refer to Figure 13).

6.3 Fine-Tune Alignment

1. Connect the D1005 Test Cable (supplied) to Pins 1,

2, and 3 of P6. These pins are located to the right of

the receiver’s terminal strip (refer to Figure 14).

If the Remote Indicator Plate connector is installed,

temporarily disconnect it.

2. Connect a 20,000 Ω/VDC VOM (or greater) to the

D1005’s black (–) and red (+) leads. Set the meter

scale so you see the readings ranging from 0 VDC

to 5 VDC.

3. Check the three receiver LEDs on the receiver.

If the receiver gets the beam, the green LED flashes

and the red and yellow LEDs are steadily on.

If the green LED is steadily on, the beam is not

reaching the receiver. Realign according to the

procedure described in Section 6.1 Preliminary

Alignment beginning on page 7.

4. Observe the meter readings. Adjust the receiver’s

optical module using the horizontal and vertical

fine-tuning adjustment screws for a maximum meter

reading.

This is the most critical alignment process.

For the most effective system operation,

ensure you have peak voltage during the

fine-tune alignment.

When performing fine-tune alignment, keep

your arms and hands away from the front of

the receiver and out of the beam path.

The maximum voltage peak reading varies,

depending on the distance between the transmitter

and receiver. The acceptable peak voltage range is

from 0.50 V to 5.00 V. The voltage at the receiver is

greater at shorter distances.

Make a note of the alignment voltage. It might be

helpful if you need to troubleshoot at another time.
