18 • 35-3000RK-10 PPM Hexane Sample Draw Detector

2. Turn off power to the controller.

3. Open the sample draw detector’s housing door.

4. Unscrew and remove the two screws that secure the sensor retraining plate, then lift

the plate, connector, and detector out of the housing.

5. Unplug the connector from the detector.

6. Verify that you are using the correct replacement sensor (SG-8521 is printed on the

sensor), then plug the sensor into the connector.

7. Place the detector in the detector chamber, then position the retaining plate on the two

standoffs.

8. Secure the retaining plate to the standoffs with the two screws you removed in Step 4.

9. Close and latch the housing door.

10. Turn on power to the controller.

11. Turn on the controller and place it into normal operation.

12. Allow the sample draw detector to run for 3 hours.

13. Make a preliminary setting of the detector load voltage. See “Setting the Detector

Load Voltage” on page 21. This will be a temporary load voltage setting since the load

voltage will need to be set again after the burn-in period as described below.

14. Perform a preliminary calibration. See “Calibration” on page 23. This will be a

temporary calibration since the new detector must burn-in before it can be properly

calibrated.

15. Allow the replacement detector to burn-in for at least 5 days before you continue with

the next step. A burn-in period of 7 days is recommended.

16. After the burn-in period, set the load voltage as described in “Setting the Detector

Load Voltage” on page 21.

17. After setting the load voltage, calibrate the as described in “Calibration” on page 23.

Replacing the Amplifier

If you are replacing the amplifier, it is likely that the sample draw detector has been off

power for an extended period. Make sure to follow the preliminary load voltage and

preliminary calibration recommendations and the burn-in period recommendation before

making the final load voltage setting and calibration. The replacement amplifier is

supplied already installed to a small mounting plate like the amplifier that is being

replaced. All references to the amplifier below refer to an amplifier already installed on

the amplifier mounting plate.

1. Turn off the controller.

2. Turn off power to the controller.

3. Open the housing door

4. Unplug the detector terminal strip and controller terminal strip from their sockets on

the amplifier. You may leave the wires connected to the terminal strips.

5. Unscrew and remove the two screws, flat washers, and split lock washers that secure

the old amplifier on its mounting plate to the mounting standoffs.

6. Remove the old amplifier with its mounting plate.

7. Install the detector and controller terminals strips into their sockets on the new

amplifier. See Figure 1 on page 5 or Figure 5 on page 22 for the location of these

terminal strips If controller leads or detector leads were removed during this

procedure, refer to Figure 4 on page 12 for wiring connections.
