This section describes the components of the 65-2301RKSS. The 65-2301RKSS includes the 65-2300RK toxic detector and a junction box. Figure 1 below shows the components of the 65-2301RKSS.

Figure 1: 65-2301RKSS Component Location

65-2300RK Toxic Detector

The 65-2300RK toxic detector consists of the detector housing body, detector housing cap, splashguard, cap gasket, and the plug- in sensor.

Page 7

Detector Housing Body

The detector housing body protects the electronic components within the housing. Use the mounting threads at the top of the housing to screw the toxic detector into a 3/4 NPT hub. Two wires extend from the top of the detector housing body. Use these wires to connect the toxic detector to a controller. One of the wires is black and one of the wires is color coded depending on the detector type. See Figure 4 on page 9 for the color code assignments.

The housing body includes a 12 position connector at the bottom of the housing body. The plug-in sensor mates to this connector. A pre-amplifier located between the connector and the two interconnect wires conditions th e s ensor’s signal before the signal reaches the controller.

Housing Cap, Cap Gasket, & Splashguard

The housing cap screws onto the detector housing. It retains the sensor and protects it from damage. A removable splashguard is screwed onto the detector cap to protect the sensor from impact dam ag e, direct water spray, and splashing. Unscrew the detector cap to access the sensor for maintenance or replacement. A cap gasket seals the interface between the housing and cap.

Plug-in Sensor

The plug-in sensor is secured in the detector assembly by the housing cap. There is a different sensor for each target gas. Through a series of chemical and electrical reactions, the sensor produces an electrical output that corresponds to the detection range of the sensor.

Junction Box

The stainless steel, corrosion resistant junction box allows you to install the detector at a mounting site that is remote from a controller, and it protects the detector wiring connections. Two conduit hubs allow you to mount the detector to the junction bo x and connect the wiring from the detector to a controller. An O-ring seals the interface between the junction box cover and the junction box base.

The terminal block within the junction box facilitates the wiring process. A cover on the front of the junction box allows access to the interior of the junction box. A locking set screw on the junction box cover allows you to secure the junction box cover and prevent it from being removed.

Installation

This section describes procedures to mount the toxic detector in the monitoring environment and wire the detector to a controller.

Mounting the Toxic Detector

1. Select a mounting site that is representative of the monitoring environment. Con sider the

3. Unscrew the detector housing cap with the splashguard from the detector housing body. Make sure not to lose the cap gasket.

4. Unplug and remove the toxic sensor.

5. Remove the black plug from the top of the replacement sensor.

6. Carefully plug the replacement sensor into the connector that is located in the detector housing body.

WARNING: You m ust replace the plug-in sensor with the same type of sensor that is installed. A

detector cannot be converted from one type of detector to another by using a different plug-in sensor. For example, if you are replacing a Cl

sensor, you must replace it with a

Cl2 sensor.

7. Make sure the cap gasket is in place and screw the detector housing cap with the splashguard back onto the detector housing body.

8. Turn on power to the controller.

9. Turn on the controller.

CAUTION: Allow the replacement sensor to wa rm up for 5 minutes before you continue with the nex t step.

10. Calibrate the detector as de scribed in “Calibration” on page 14.

Replacing the Toxic Detector

NOTE: In most cases, it is only necessary to replace the plug-in sensor.

1. Turn off the controller.

2. Turn off or unplug incoming power to the controller.

3. Remove the junction box cover.

4. Disconnect the detector leads from the terminal block in the junct ion box. Note the po s i ti on of the color-coded leads as you remove them.

12 • 65-2301RKSS Toxic Detector

Page 13

5. Unscrew the detector from the controller conduit hub or junction box conduit hub.

6. Guide the detector leads of the replacement detector through the junction box conduit hub, then screw the mounting threads of the detector into the hub. If necessary for environmental conditions, apply thread sealant or Teflon tape to the hub and/ or detector threads to seal them.

7. Connect the detector leads to the terminal block the same way the old detector was wired (see Figure 4 on page 9). See the controller operator’s manual and the controller’s detector head specification sheet for the 65-2301RKSS to verify the connections to the controller are correct.

8. Reinstall t he junction box cover.

9. Turn on or plug in power to the controller.

10. Turn on the controller.

CAUTION: Allow the replacement detector to warm up for 5 minutes before you cont in u e wi th the next step.

11. Calibrate the replacement detector as described in “Calibration” on page 14.

Calibration Frequency

Although there is no particular calibration frequency that is correct for all applications, a calibration frequency of every 3 months is adequate for most toxic detector applications. Unless experience in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration frequency of every 3 months for the toxic detector.

If an application is not very demanding, for example detection in a clean, temperature controlled environment where toxic gas is not normally present, and calibration adjustments are minimal at calibration, then a calibration freque nc y of every 6 months is adequate.

If an application is very demanding, for example if the environment is not well controlled or if toxic gas is often present, then more frequent calibration than every 3 months may be necessary.

) gas and that you do not use that dedicated regulator for any other gases,

particularly hydrogen sulfide (H2S).

WARNING: Not using the recommended calibration cup, sample flowrate, and specified flow

direction (for 81-1138RK calibration cup only) will result in an inaccurate calibra ti on. Make sure to use the calibration cup and sample flow rate listed in Table 2 for your target gas when performing a calibration. Also make sure to connect the sample tubing to the calibration cup port that results in the specified flow direction for the 81-1138RK calibration cup.

Preparing for Calibration

1. Unscrew the splashguard fro m the detector housing cap. Make sure the cap remains securely screwed onto the housing body.

2. Push the calibration cup onto the plug-in sensor that sticks through the housing cap. The calibration cup seals to the sensor with an O-ring.

3. Screw the regulator into the zero air calibration cylinder.

4. Use the sample tubing to connect the regulator to the calibration cup. Make sure to connect the tube to the inlet side of the calibration cup if using the 81-1138RK calibration cup which is marked on the outside bottom to show the required flow direction through the cup.

NOTE: If you can verify that the toxic detector is in a fresh air environment, you do not need to apply

zero air to the detector before adjusting the fresh air reading.

5. Put the controller into its calibration program. See the controller operator’s manual for instructions to enter the calibration program.

Setting the Zero (Fresh Air) Reading

1. Follow the instructions in the con troller operator’s manual for setting the zero reading.

2. When the instructions call for appl ying zero air to the detector, turn the regulator’s on/off knob counterclockwise to open it. Gas will begin to flow.

3. Allow the gas to flow for two minutes.

4. Set the fresh air reading according to the controller operator’s manual.

5. Turn the regulator’s on/off knob clo c kwise to close it.

6. Unscrew the regulator from the zero air calibration cylinder. Leave the sample tubing connected to the regulator and the calibration cup.

NOTE: Depending on the size of your zero air cylinder, it is possible that you will have a different

regulator for the zero air cylinder and toxic gas cylinder. If necessary to fit the calibration toxic gas cylinder, change the regulator.

Setting the Response Reading (Span)

1. Screw the regulator into the calibration gas cylinder.

2. Follow the directions in the contro ller operator’s manual for setting the response (span) reading.

3. When the directions call for exposing the detector to gas, turn the regulator’s on/off knob counterclockwise to open it. Gas will begin to flow.

4. Allow the gas to flow to the detector for 2 minutes.

5. Set the response reading according to the controller operator’s manual.

6. After setting the response reading, turn the regulator’s on/off knob clockwise to turn it off.

7. Unscrew the regulator from the cylinder and gently pull the calibration cup off of the plug-in sensor.

NOTE: For convenience, leave the regulator and calibration cup connected by the sample tubing.

8. Allow about 45 seconds for the gas reading to decrease below the alarm points and then return the controller to normal operation.

NOTE: If you do not allow the gas reading to decrease below the alarm points, then un wanted

alarms may occur.

9. Verify that the controller display reading d ecreases a nd stabilizes at 0 ppm.

10. Store the components of the calibra tion kit in a safe and convenient place.
