Chapter 3: Operation
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. Four
channels are displayed on each of the four displays visible through the front panel. On each display the
channel sequence starts at the top and goes down. For example, on the upper left display, channel 1 is
the top reading and channel 4 is the bottom reading.
The PILOT light on the front panel, the POWER light on the main circuit board, and the pilot light on each
analyzer card are on during normal operation 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 3-1 lists the alarm indications for each condition.
