Introduction
The Gasgard 8 Gas Monitor is designed for remote monitoring of
up to eight input sensors (two or three-wire 4-20 mA). Calibration
of the sensor is performed at the sensor location and does not
require calibration adjustments at the monitor, reducing the
personnel required for calibration.
The Gasgard 8 Monitor offers many features and options,
available through easy-to-program software. These features and
options are accessed through the front panel control buttons.
Features
The Gasgard 8 Monitor is designed with easy-to-program
software, allowing the user to set:
•
Full-scale range for the connected 4-20 mA sensor
•
Alarm level setpoints for each of the four alarm levels
•
Alarm on an upscale or downscale gas reading
•
Relays as energized or de-energized
•
Alarms as latching or non-latching
•
Buzzer output as enabled or disabled
•
External alarm reset switch or flow failure fault status
•
Time and Date.
These software settings are stored in memory and, due to an
internal battery, remain preserved even with a loss of power.
In addition, the alarm and fault relays are jumper configurable as
normally-opened or normally-closed. The Gasgard 8 Gas Monitor
control and indicator features are shown in FIGURE 1-1.
