Figure 5: Main PCB
The main PCB is located on the right side of the bottom case. It slides into
guiding grooves at the bottom, front, and rear of the bottom case. It is held in
place by the top case. Connectors for the sensors, differential pressure switch,
pump, display PCB, optional float probe, and I.S. barrier PCB are located on
the main PCB. In addition, an IR transmitter/receiver is located at the front of
the PCB behind the IR port on the front of the bottom case.
Alarm LEDs
Two sets of red alarm LEDs (light emitting diodes) are visible through two
raised, frosted plastic lenses in the top case. Each set has two LEDs. They are
above the LCD, one above the left corner and one above the right corner. The
alarm LEDs alert you to gas, low battery, and failure alarms.
Infrared Communications Port
An infrared (IR) communications port is located on the left front of the
bottom case when the instrument is viewed from the front. The data
transmitted through the port is in standard IrDA protocol. A computer’s
