About the M2 Rig Monitor
The M2 Rig Monitor is a fixed mount, continuous-monitoring detector head. All user
adjustable parameters may be accessed using push button switches. In addition,
calibration may be performed non-intrusively by use of a magnetic wand accessory which
activates magnetic switches through a window at the front face of the detector head.
The Rig Monitor displays the current gas reading on an LCD display which is visible
through the window in the cover (front face) and provides a 4 - 20 mA signal which
indicates the target gas reading for use by a gas monitoring controller, recording device, or
programmable controller. The Rig Monitor also provides an RS-485 Modbus output. Three
sets of relay contacts, two controlled by the gas alarms and one by the fail alarm, rated at
115 VAC 5 amps are available for controlling devices such as lights or horns or for
controlling higher rated relays. The alarm 1 relay is factory wired to the strobe/horn.
Three operating modes allow you to display and change setup and calibration settings.
They are Calibration Mode, Configuration Mode, and Modbus Mode.
