The junction box also protects the M2 and all connections made to it. A variety of detectors may be used with the M2. Table 2 below lists the detectors that can be used with the M2.

Page 12 The charcoal filter disk scrubs out interfering gases to which the CO sensor responds such as H S and certain hydrocarbons. Page 14 You can then push the appropriate ESM calibration cup onto the sensor. Page Internal Description This section describes the internal components of the M2. The internal components of the M2 include the terminal PCB which provides for all the wiring connections to the M2 and the control PCB which displays the gas reading and has the control buttons.

Page 17 A two pin header with a termination jumper installed is located below the Modbus terminal strip. The jumper has no function unless the M2 is wired into a Modbus installation.

A fail condition can be caused by a detector failure or low detector signal. Consider the following when you select the mounting site. Make sure there is sufficient room to perform start-up, maintenance, and calibration procedures. Mounting 5. Remove the junction box cover. Grasp the control PCB by its edges. Gently pull until the control PCB is pulled away from the banana jacks. Page 26 The number of cables or wires needed will depend on whether the M2 is wired to a gas monitoring controller or just to power, whether any relays are used, and whether the Modbus output is used.

Verify that the M2 is in a fresh air environment environment known to be free of the target gas and combustible or toxic gas vapors and of normal oxygen content, ENTER will alternate with FreshAir on the top display line and the current gas reading will be on the bottom display line. This chapter also describes the M2 in alarm 1, alarm 2, and fail conditions and suggests responses to these conditions. For oxygen types, the output will be fixed at Responding to an Alarm 2 Condition Follow your established procedure for a high level combustible or toxic gas condition or an increasing oxygen concentration condition.

When the voltage increases to Responding to a Low Power Condition Determine and correct the cause of the low power condition. Table 6 lists the M2 parameters you can set. Table 6 also lists the factory set value for each parameter. Page 36 15 minute increments from 15 - 60 minutes. A1 OffDy alarm 1 off delay The amount of time the M2 delays turning off the alarm 1 circuit once an 0 sec.

The Re-do Config message will display and the M2 will return to the first adjustable parameter. Go back to step 3 and continue. The gas type determines the target gas and detection range. Your M2 will only have gas type choices available that it can support.

NOTE: When calibrating an M2 after changing the gas type, the M2 will not ask if you want to calibrate, or whether you want to perform a fresh air adjustment, span adjustment or zero adjustment. The RKI M2 is a state-of-the-art transmitter that can operate as an independent, stand-alone system or as part of an integrated system. Setup procedures are simplified with user friendly push buttons and LCD menus. It utilizes a magnetic wand technique for performing non-intrusive calibration. The M2 provides an automatic zero drift correction feature, which results in more stable readings and reduces the need for adjustments due to sensor aging.

The housing of the M2 does not need to be opened for zeroing or calibration, making it unnecessary to declassify the area for routine maintenance.

It is designed so that a complete field calibration can be performed by one person. Sensor construction is rated Class I, Div.
