Alarm System

3.3.1

General Description of Alarm Processing

The Series 9510 Carbon Dioxide Analyzer is equipped with four single pole double throw  (SPDT) relays
with Form C contacts rated at 10 amperes @ 30 VDC and 115/230  VAC.  All alarm relays are user
configurable with the front panel controls of the instrument and the configuration switch  SW6. When an
alarm event takes place, several indications are provided by the  analyzer:

1. The LED associated with the CO

2

 alarm in question will light.

2. An audible alarm will sound.
3. The relay associated with the CO

2

 alarm in question will change state.

If the alarm event was associated with the instrument status, only the relay associated with the instrument
status alarm will change state.  Alarm processing and behavior is controlled via  SW6  (Figure 3.0) and/or
the user settings saved in the battery backed-up RAM associated with the microprocessor.

3.3.2

Default / User Settings

With switch #8 of SW6 in the "OFF" position, the Series 9510 Carbon Dioxide Analyzer uses the settings
of switches #1 - #7 for instrument alarm configuration.  This includes the default alarm level for Alarm #3,
determined by the position of switch #7 (Alarms #1 & #2 are factory defaulted to LOW alarm levels).   With
switch #8 in the "ON" position, all user settings will be retained , whether determined through the switch
settings or the optional communications interface .  Note:  to read the switches while operating, initiate a
"warm boot". (See Section 3.2.1 )

IF ANY ALARM IS NOT GOING TO BE USED, IT SHOULD
BE DISABLED.  TO DO SO, FIRST CONFIGURE EACH
ALARM AS A LOW ALARM, AND THEN SET THE ALARM
TO 0.00.
