Pioneer Operator’s Manual CO Transmitter • 7
Start Up
This section describes procedures to start up the CO transmitter and place the transmitter
into normal operation.
Introducing Incoming Power
1. Complete the installation procedures described earlier in this insert.
2. Verify that the power wiring is correct and secure (see Chapter 3, Installation and
Start Up.)
3. Turn on or plug in the incoming power at the power source end, then place the
Pioneer’s power switch in the ON position.
4. Verify that the main PILOT light is on and the pilot light for each analyzer card is
flashing.
Setting the Zero Signal
CAUTION: If you suspect the presence of the target gas in the monitoring environment, use the
calibration kit and the zero air calibration cylinder to introduce “fresh air” to the
sensor and verify an accurate zero setting.
1. Verify that the transmitter is in a fresh air environment (environment known to be free
of carbon monoxide).
2. Unscrew and remove the junction box cover from the junction box.
3. Set a voltmeter to measure in the millivolt (mV) range.
4. Plug the voltmeter leads into the test points on the amplifier. Plug the positive lead
into the test point labeled
TP+ ; plug the negative lead into the test point labeled TP- .
5. Verify a voltmeter reading of 100 mV (±2 mV).
6. If necessary, use a flat-blade screwdriver to adjust the zero potentiometer until the
voltmeter reading is 100 mV (±2 mV).
7. Secure the junction box cover to the junction box.
Channel Setup Program
This section describes the Pioneer’s Channel Setup program for the CO transmitter.
You can display and change the following channel settings with the Channel Setup
program.
• Channel Status
• Target Gas, Unit of Measure, and Fullscale Setting
• Relay 3 Assignment
• Alarm Setpoints and Alarm Type (rising or falling)
NOTE: Channels that are included with the original shipment of the Pioneer are setup at
the factory. If you are adding a channel to an existing Pioneer, you need to
establish the channel settings in this program.
