4 INITIAL STARTUP
When power is applied to the GASMAX CX, the screen will show ‘GASMAX CX” followed by one or two
Smart Sensor information screens if the sensor(s) are locally connected. Certain sensors may initially
indicate off ‐ scale high or low values, but should quickly return to zero within a few minutes if no target
gas is present. During this warm ‐ up delay period, the 4 ‐ 20mA output is held at 4.0 mA to eliminate false
alarms in any receiving devices.
GASMAX USER INTERFACE
The GASMAX CX display is shown in Figure 5 ‐ 1. There are four magnetic switches on the face of the
GASMAX CX, arranged in a quadrant around the LCD display; these are labeled NEXT, EDIT, DOWN/CAL
and UP. To activate, or “press” a magnetic switch, swipe the magnetic wand near the switch. For the
balance of this manual, the term “press” will be used to describe activation of any key via the magnetic
wand.

Pressing the NEXT key causes the GASMAX display to switch display screens . In single channel mode, the
display will switch between DATA and TREND. In dual channel systems, the sequence will be: DATA 1,
DATA 2, TREND 1, TREND 2, DUAL CHANNEL, followed by DATA 1.
