the front panel). For full Calibrator and Controller operational
details, refer to instruction manual (P/N 813379).
Internal Push-buttons
A pair of internal push-buttons on the Toxgard II main pc board,
lower-right corner (FIGURE 1-1) can be used in place of the
Ultima Controller and Calibrator for most functions.
The right-hand button marked "CAL" is used to initiate all
instrument calibration functions, eliminating the need to use the
Controller or Calibrator to perform calibration.
The left-hand button marked "MODE" allows the user to scroll
and view the Toxgard II configuration parameters. This operation
is comparable with the Controller "send display item" feature.
Viewing Configuration Parameters
At initial installation, use the Toxgard II MODE push-button
(FIGURE 1-1) to review the Toxgard II configuration parameters.
To scroll, press and release the MODE push-button. The Toxgard
II Monitor:
• temporarily stops displaying gas measurement readings
• displays a value and other relevant information for a parameter
(TABLE 1-7).
NOTE: Pressing and releasing the MODE push-button
within 10 seconds enables the user to scroll to the
next parameter. If the user does not press the
push-button within 10 seconds, the Toxgard II
Monitor ends the parameter viewing mode and
returns to a display of the actual gas measurement.
The Toxgard II Monitor is able to detect and notify
the user of a hazardous condition even while
scrolling the parameters. Although the LED
continues scrolling, the hazardous condition is noted
by the horn, relays and strobes (if equipped). When
the scroll list ends, the LED display will show the
alarm condition and gas measurement value.
