Sample-Draw Combustible Gas Detection Overview This manual describes the Model 1017-01 sample draw combustible gas detector. This manual also describes how to install, start up, maintain, and calibrate the Model 1017-01. A parts list at the end of this manual lists replacement parts and accessories. Specifications Table 1 lists specifications for the Model 1017-01.
Description This section describes the components of the Model 1017-01. The Model 1017-01 consists of the housing and subpanel assembly. Terminal Plate Housing, (Shown w/out Lid) Sensor Terminal Strip Subpanel Assembly 6 Pump 4 5 Combustible Sens or Mounting Plate Inverter (Under Terminal Plate) + 24V DC IN 3 LEL Sensor 3/4 NPT Conduit Opening (on side of housing) Input Power Terminal Strip Ground Screw Flame Arrestor Fitting, 2X Mounting Foot, 2X Exhaust Fitting, For 1/4 O.D.
In Inlet LEL Out Pump Exhaust Figure 2: Model 1017-01 Flow Diagram Subpanel Assembly All the internal components of the Model 1017-01 are part of the subpanel assembly. It is mounted to the inside of the housing. The subpanel assembly consists of an aluminum subpanel with the following components mounted on it: the terminal plate, the inverter, the pump, the sensor block, and the combustible sensor (see Figure 1). Terminal Plate The terminal plate is mounted on the right side of the subpanel.
Installation This section describes procedures to mount the Model 1017-01 in the monitoring environment and wire it to a controller. 1. Select the mounting site. Consider the following when you select the mounting site. • Is there enough room to remove the cover and make wiring connections at the right side of the housing and tubing connections at the bottom of the housing? • Is there is sufficient room to perform start-up, maintenance, and calibration procedures? 3/8 Mounting Bolts (2X) 8.38 7.00 .
Connecting the Sample Lines to the Model 1017-01 1. Attach 1/4 inch O.D. rigid sample tubing to the INLET fitting. CAUTION: If you use flexible sample tubing (vinyl or polyurethane for example), use an appropriate metal insert to seal the connection between the tubing and the INLET fitting. See the Parts List for an example of an appropriate metal insert. 2. Place the opposite end of the tubing at the sampling area. CAUTION: Avoid loops or slumps in the incoming sample line.

Start Up This section describes procedures to start up the Model 1017-01 and place it into normal operation. Introducing Incoming Power 1. Complete the installation procedures described earlier in this manual. 2. Verify that the sensor and power wiring are correct and secure. 3. Turn on or plug in the incoming power at the power source end. 4. Verify that the flow rate is 1.0 LPM with a flowmeter. If necessary, adjust the flow with the valve that was installed. 5.
Maintenance This section describes maintenance procedures. It includes preventive maintenance procedures. This section also includes procedures to troubleshoot the Model 1017-01 and replace components. Preventive Maintenance This section describes a preventive maintenance schedule to ensure the optimum performance of the sample-draw detector. It includes daily and quarterly procedures. Daily 1. Verify that the recommended flow indicator is indicating flow. 2.
Probable causes • The calibration cylinder is low, out-dated, or defective. • The Model 1017-01’s flow rate is too low because of an obstructed sample line, failed pump, etc. • The Model 1017-01’s inverter is malfunctioning causing a low flow rate. Recommended action 1. Verify that the calibration cylinder contains an adequate supply of a fresh test sample. 2. If necessary, set the correct flow rate. 3. If you cannot set the correct flow rate, check the sample line for obstructions or kinks.
NOTE: Make sure the bottom ferrule is laying flat in the nut. 4. Insert the cone-shaped front ferrule on top of the bottom ferrule. Insert the ferrule so the smaller end of the cone is facing up. 5. Screw the nut onto the fitting, then connect the sample tubing to the fitting. Make sure you firmly tighten the tubing to the fitting. Calibration This section describes how to calibrate the Model 1017-01.
3. Allow the Model 1017-01 to draw sample for one minute. 4. Follow the directions in the controller’s operator’s manual for setting the span. 5. Disconnect the sample tubing from the inlet fitting. 6. Unscrew the regulator from the combustible gas calibration cylinder. Returning to Normal Operation 1. Reconnect the incoming sample line. 2. Wait approximately one minute to allow the combustible gas reading to stabilize. 3.
