Start Up
This section describes procedures to start up the Model 1017-05 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 2.0 SCFH with a flowmeter. If necessary, adjust the flow
with the valve that was installed.
5. Verify that the recommended flow indicator is indicating flow.
6. Allow the sensor in the Model 1017-05 to warm-up for 5 minutes before continuing.
Setting the Zero Reading
CAUTION: If you suspect the presence of combustible gas in the monitoring environment, use a
zero air calibration cylinder to introduce “fresh air” to the sensor and verify an
accurate zero setting.
1. Verify that the Model 1017-05 is sampling a fresh air environment (environment
known to be free of combustible gas).
2. Verify a reading of 0% LEL at the controller.
If the display reading is 0% LEL, start up is complete. The Model 1017-05 is in normal
operation. If the display reading is not 0, continue with step 3.
CAUTION: Normally the Model 1017-05 is tested and calibrated with a controller and delivered
with a controller. If your Model 1017-05 was not calibrated with the controller at the
factory because you are replacing or adding a detector head, perform a complete
calibration. See the Calibration section for calibration instructions.
3. See the controller instruction manual for instructions on setting the zero reading at the
controller.
