actuate them. Although the magnetic switches have the same functions as the push button
switches, it is not practical to use them for operations other than calibration because it is
not possible to actuate two magnetic switches at once with only one magnetic wand. Since
displaying the Information Screen only requires the use of one switch, the wand may be
used to show the Information Screen (see “Information Screen” on page 25).
Status LEDs
The M2 includes five status LEDs that are located above the display (see Figure 9).
• Fail LED
The fail LED turns on when the M2 is experiencing a fail condition. A fail condition
can be caused by a detector failure or low detector signal.
• Alarm 1 LED
The alarm 1 LED is on when the M2 is experiencing an alarm 1 condition.
• Alarm 2 LED
The alarm 2 LED is on when the M2 is experiencing an alarm 2 condition.
• RX & TX LED’s
These LED’s indicate data being received (RX) and transmitted (TX) when the M2’s
Modbus output is operating.
