Chapter 4: Operation

Overview

This chapter describes the Pioneer Gas Monitor in normal operation. This chapter also
describes the Pioneer in alarm 1, alarm 2, alarm 3, and fail conditions and suggests
response to these conditions. The Instrument Setup program and Display Setpoints and
Readings program are described at the end of this chapter.

Normal Operation

Normal operation is defined as follows:

the start-up procedure is complete.

the Pioneer is not indicating an alarm 1, alarm 2, alarm 3, or fail condition.

the Pioneer is not running the Instrument Setup, Channel Setup, Calibrate, or
Display Setpoints and Readings program.

During normal operation, the Pioneer simultaneously displays the target gas, unit of
measure, and current gas reading for all active channels. The Pioneer displays the
readings horizontally for each channel. If all four channels are installed, channel 1 is the
top reading, and channel 4 is the bottom reading.

The PILOT light near the display screen, the POWER light on the main circuit board, and
the pilot light on each analyzer card are on during normal condition indicating that the
monitor and analyzer cards are receiving incoming power. The output at terminals 8 and 9
of the analyzer card’s output terminal strip is 4 to 20 mA

or

0 to 1 V and is proportional to

the detection range of the detector that is wired to the analyzer card. (The standard output
at terminals 8 and 9 is 4 to 20 mA.)

Alarm Indications

This section describes the Pioneer in alarm 1, alarm 2, alarm 3, and fail conditions and
suggests response to these conditions. Table 4-1 lists the alarm indications for each
condition.

NOTE:

The Pioneer includes alarm on and alarm off delay settings. The alarm
indications described in this section operate according to the default delay
settings. See the Channel Setup program section in the applicable detection insert
(Appendix B, Gas Detectors) to display or change the alarm on and alarm off

delay settings.
