LEL Detector

Figure 1: 61-0140RK LEL Detector Component Location

The combustible gas detector is a catalytic type detector that produces an electrical output that corresponds to the detection range. It is packaged in a 1/2 inch NPT nipple with a sintered metal flame arrestor on one end allowing ambient air to diffuse into the detector. The flame arrest or al so co ntai n s any s park s whi ch may occur within the detect or. The 1/2 inch NPT mounting threads at the top of the detector allow you to install it in the bottom conduit hub of the junction box with the use of a 3/4 in. x 1/2 in. NPT reducer. A rainshield screws onto the bottom of the detector (flame arrestor end). The rainshield helps protect the detector from rain and debris in the monitoring environment. Four colorcoded leads extend from the top of the detector. The leads allow you to connect the detector to the terminal block.

Start Up

9. Connect the cable’s dr ain wire to an available chassis ground at the controller. RKI controllers typically have a ground stud that can be used to ground the cable’s drain wire.

This section describes procedures to start up the multi-point detector and place the detector into normal operation.

Introducing Incoming Power

1. Complete the installation procedures described earlier in this manual.

2. Verify that the power wiring to the controller is correct and secure. Refer to the controller operator’s manual.

3. Tu rn on power to the controller.

4. Turn on the controller.

5. Verify that the controller is on and operating properly. Refer to the con troller operator’s ma nual.

CAUTION: Allow th e multi-point detector to warm up for 5 minutes before you continue with

the next section, “Setting the Zero (Fresh Air) Reading”.

Setting the Zero (Fresh Air) Reading

CAUTION: If you suspect the presence of a target gas in t he monitoring environment, use the

calibration kit and a zero air calibration cylinder to introduce “fresh air” to the desired detector and verify an accurat e zero setting. See the Calibration section for instructions to introduce zero air to the desired detector.

1. Verify that the detector is in a fresh air environment (environment known to be free of toxic and combustible gases, and of normal oxygen content, 20.9%).

2. At the controller, verify a reading of:

• 0 %LEL for combustible gas

• 20.9% for oxygen

• 0 ppm for H If the display reading is the appropriate fresh air reading, start up is complete. The

detector is in normal operation. If the display reading is not the appropriate fresh air reading, continue with step 3.

3. Perform a zeroing (fresh air adjustment) operation at the controller. See the controller operator’s manual for directions.

Maintenance

This section describes maintenance procedures. It includes preventive maintenance, troubleshooting, and component replacement procedures.

Preventive Maintenance

This section describes a preventive maintenance schedule to ensure the optimum performance of the multi-point detector. It includes daily, monthly, and quarterly procedures.

Daily

At the controller, verify a display reading of:

• 0 %LEL for combustible gas

• 20.9% for oxygen

• 0 ppm for H

S, CO, or toxic ESM-01 channel

Investigate significant changes in the display reading.

Monthly

This procedure describes a test to verify that each detector in the multi-point detector responds properly to its target gas. It describes a test using a fixed flow regulator with an on/off knob. RKI Instruments, Inc. recommends using a 0.5 LPM (liters per minute) fixed flow regulator for the LEL, O

, H2S, or CO channels. See Table 3 on page 33 to determine

the correct calibration cup and regulator for the ESM-01 toxic channel.

WARNING: The ESM-01 detector calibration cup is different than that of the LEL/O2/

S/CO detectors. Ensure that you are using the correct calibration cup for

the detector you are testing. See “Calibration, ESM-01 Toxic Detector” on page 33.

NOTE: Performing a response test on the multi-point detector may cause alarms. Be sure

to put the controller into its calibration program or disable external alarms befor e performing this test.

Preparing for the response test

1. Place the controller into its calibration program or disable external alarms.

2. Verify tha t the controller display reading for the channel you are testing is:

• 0 %LEL for combustible gas

• 20.9% for oxygen

• 0 ppm for H

S, CO, or toxic ESM-01 channel

If the display reading is not the appropriate fresh air reading, set the zero reading of the detector as described in the Start Up section of this manual, then continue this procedure.

3. Screw the calibration cup onto the bottom of the detector you are testing if you are testing an LEL, O

, H2S, or CO detector. If you are testing the ESM-01 detector,

unscrew the splashguard before pushing on the calibration cup.

4. Screw the regulator into the calibration cylinder.

65-2484RK Multi Point Detector • 21

NOTE: Ensure that you are using an appropriate calibration cylinder for the channel you

are testing.

5. Use the calibration kit sample tubing to connect the regulator to the calibration cup. If you are testing the ESM-01 toxic detector, check the bottom of the calibration cup to see if it has a specified flow direction through the cup and if it does, ma kes sure you connect the tube from the regulator to the inlet port. The 81-1138RK calibration cup, which is used for all detectors except for Cl

and NH3 detectors, has a specified flow

direction on the bottom of the cup. The 81-1138RK-CL2 and 81-1138RK-NH3 calibration cups do not have a specified flow direction.

Performing the response test

1. Turn the regulator’s on/off knob counterclockwise to open the regulator. Gas will begin to flow.

2. Allow the gas to flow for one minute for the LEL detector or two minutes for the O H

S, CO, and ESM-01 detectors, then verify that the reading is within ± 20% of the

cylinder gas concentration.

NOTE: If the reading is not within ± 20% of the correct response reading, calibrate the

detector as described in the Calibration section of this manual.

3. Turn the regulator’s on/off knob clockwise to close the regulator.

4. Unscrew the regulator from the calibration cylind er.

5. For any additional detectors that you want to test, move the calibra tion cup to the detector, screw the regulator into the appropriate gas cylinder and repeat steps 1-4.

6. Unscrew the calibration cup from the detector if you are testing an LEL, O

, H2S, or

CO detector. If you are testing the ESM-01 detector, screw the splashguard back onto the detector.

7. When the controller display reading falls below th e alarm setpoints, return the controller to normal operation.

8. Store the components of the calibration kit in a safe place.

Quarterly

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 multi-point detector applications. Unless experience in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration frequen cy of every 3 months for the catalytic LEL, oxygen, H

detector. If an application is not very demanding, for example detection in a clean, temperature

controlled environment, and calibration adjustments a re minima l at calibration, then a calibration frequency of every 6 months is adequate for the catalytic LEL, oxygen, H

CO, and ESM-01 detectors and every 9 to 12 months is adequate for the infrared LEL detector.

If an application is very demanding, for example if the environment is not well controlled, then more frequent calibration than every 3 months for the catalytic LEL, oxygen, H

CO, and ESM-01 detectors and every 6 months for the infrared LEL detector may be necessary.

Prepari ng for Ca libration

WARNING: Do not remove the junction box cover or detector housing cap while the

circuits are energized unless the area is determined to be non-hazardous. Keep the junction box cover and detector housing cap tightly closed during operation.

1. Screw the calibration cup onto the bottom of the detector you wish to calibrate.

NOTE: If you can verify that the multi-point detector is in a fresh air environment, you

do not need to apply zero air to the detector before adjusting the zero reading.

2. Screw the regulator into the zero air calibration cylinder. Make sure the regulator is off. It is off when the on/off knob is turned all the way clockwise.

3. Use the calibration kit sample tubing to connect the fixed flow regulator to the calibration cup.

4. Put the controller into its calibration program. See the controller operator’s manual

30 • 65-2484RK Multi Point Detector

for instructions to enter the calibration program.

NOTE: RKI controllers have a minimum hold feature for zero adjustment and a peak

hold feature for span adjustment. Because of this, the instructions call for turning off the gas to a detector before making adjustments.

Setting the Zero Reading

1. Follow the directions in the controller operator’s manual for setting the zero reading.

2. When the instructions call for applying z e ro 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. Turn the regulator’s on/off knob clockwise to close it.

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

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

Setting the Response Reading

1. Screw the regulator into the calibration gas cylinder. Make sure the regulator is off. It is off when the on/off knob is turned all the way clockwise.

NOTE: Ensure that you are using an appropriate calibration cylinder for the channel you

are calibrating.

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

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 gas to flow for 1 minute for the LEL detector or 2 minutes for the H detectors before continuing with the directions.

5. Turn the regulator’s on/off knob clockwise to close it.

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

7. Unscrew the regulator from the cylinder.

Calibration, O2 Detector

This section describes how to calibrate the oxygen detector on the multi-point detector. It includes procedures to prepare for calibration, set the fresh air reading, set the zero reading, and return to normal operation. It describes calibration using a calibration kit that includes an 81-111 7RK calibration cup, calibration gas, sample tubing, and a fixed flow regulator with an on/off knob. RKI Instruments, Inc. recommends using a 0.5 LPM (liters per minute) fixed flow regulator. To properly calibrate the multi-point detector, you must calibrate each connected detector. Perform the following procedure for the oxygen detector.

W ARNING: The controller is not an active gas monitoring device during the calibration

procedure.

Prepari ng for Ca libration

WARNING: Do not remove the junction box cover or detector housing cap while the

circuits are energized unless the area is determined to be non-hazardous. Keep the junction box cover and detector housing cap tightly closed during operation.

1. Screw the calibration cup onto the bottom of the oxygen detector.

2. Screw the regulator into the zero air calibration cylinder. Make sure the regulator is off. It is off when the on/off knob is turned all the way clockwise.

NOTE: If you can verify that the multi-point detector is in a fresh air environment, you

do not need to apply zero air to the detector before adjusting the fresh air reading.

3. Use the calibration kit sample tubing to connect the fixed flow regulator to the calibration cup.

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

NOTE: RKI controllers have a peak hold feature for fresh air adjustment and a minimum

hold feature for zero adjustment. Because of this, the instructions call for turning off the gas to a detector before making adjustments.

Setting the Fresh Air Reading

1. Follow the directions in the controller operator’s manual for setting the fresh air reading.

2. When the instructions call for applying z e ro 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. Turn the regulator’s on/off knob clockwise to close it.

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

32 • 65-2484RK Multi Point Detector

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

Setting the Zero Reading

1. Screw the regulator into the 100% nitrogen calibration gas cylinder. Make sure the regulator is off. It is off when the on/off knob is turned all the way clockwise.

2. Follow the directions in the controller operator’s manual for setting the zero 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 gas to flow for 2 minutes before continuing with the directions.

5. Turn the regulator’s on/off knob clockwise to close it.

6. Set the zero reading according to the controller operator’s manual.

7. Unscrew the regulator from the cylinder.

Returning to Normal Operation

1. Unscrew the calibration cup from the oxygen detector.

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

sample tubing.

2. When the controller display reading rises above the alarm points, return the controller to normal o peration.

NOTE: If you do not allow the gas reading to rise above the alarm points, then unwanted

alarms may occur.

3. Verify that the controller display reading increases and stabilizes at 20. 9% oxygen.

4. Store the components of the calibration kit in a safe and convenient place.

Calibration, ESM-01 Toxic Detector

This section describes how to calibrate the ESM-01 type toxic detector. It includes procedures to prepare for calibration, set the fresh air reading, set the response reading, and return to normal operation. It describes calibration using a calibration kit that includes an 81-1138RK-XX calibration cup, calibration gas, sample tubing, and a fixed flow regulator with an on/off knob. The required sample flow rate and calibration cup depend on the detector being calibrated. Table 3 below lists the required calibration cups and regulators for the various toxic detectors.
