MAIN SCREEN
After the sign-on screens show the company name, firmware version, check-sum, and the time and date, the
stabilize delay timer is displayed (see left display above). Alarms associated with the gas sensors are inhibited,
which are loss of signal and set point alarms (danger and critical). One can exit this screen by pressing ESC. The
stabilization delay timer will continue counting down, which is indicated on the main screen display. "DLY" is briefly
displayed on the left side of the screen. During the stabilize delay timer count down, any gas concentration values
displayed are not considered valid. The 4-20mA analog outputs are held to 4mA.
After the stabilization delay timer has expired, the main screen is displayed. The gas type, channel number, gas
concentration, and units are displayed. If only one gas sensor is active, the bottom line displays a bar graph scaled
to the 4-20mA PO1 output level. Press any one of the four push-buttons to display the MAIN MENU. The alarm
status for each channel is indicated by flashing DGR (danger) or CRT (critical) on the left side of the display (see
right display image above).
Note: The alarm will sound only when the main screen is displayed is so it will not activate during calibration, alarm
set point adjustments, etc. This is the reason many screens will time out and return to a previous screen until the
main screen is again displayed. The danger and critical set point outputs will remain active regardless of the screen
that is displayed with one exception: All sensor alarms are deactivated during calibration (i.e., when one is
accessing one of the calibration screens or menus). The 4-20mA outputs are forced to 4mA during the sensor
calibration.
MAIN MENU SCREEN
TST: Press and hold this selection to access the relay/horn test screen.
LOG: Access the clock, hour meter and log screens.
STAT: View the status of the switch inputs (if active) and the current alarm status.
MNU: Access the calibration, configuration and alarm selection menu.
(TST) RELAY (HORN) TEST SCREEN
When this screen is activated by pressing TST in the main menu screen, all relays
are de-energized for ¼ second and then powered one-by-one until all six are
energized. If the internal horn is enabled, it will sound for ½ second. This screen is
displayed until TST (PB4) is released.
LOG (Event log)
See the EVENT LOG SECTION later in this manual. The LOG sub menu is where one can view the event log, view
and set the time and date, and view the hour counter.
(STAT) RELAY STATUS SCREEN
This screen displays the monitor input and output status for troubleshooting in the field.
The information displayed includes the danger (DGR) and critical (CRT) set point
status for each channel, loss of signal, active switch inputs (IN0 and IN1), auto-dialer
output is active, and failure output is active.
Screen time-out is two-minutes (returns to main screen).
