CONFIGURATION PROCEDURE
Page: 33
4. CONFIGURATION PROCEDURE
4.1 INTRODUCTION
Sentry is operated via the seven keys on the front panel.
Operation includes initial set-up, periodic calibration,
recall of history, and changes to configuration.
Certain procedure and message conventions are used to
provide consistency. A knowledge of these conventions
will aid in understanding of the set-up and operation steps.
The UP and DOWN arrow keys change information
displayed on the alpha-numeric (lower) display. Changes
made by using the arrows are not "implemented" until the
ENTER key is pressed.
The ENTER key is used to access the selected activity or to
enter selected data or status information into the controller
memory.
When any of the four activity keys TEST, RESET, TIME,
MODE are depressed the SENSOR/LEVEL display is
cleared and the activity information is displayed on the
alpha-numeric display.
The messages PRESS ENTER TO or ENTER TO indicate that
the selected activity can be accessed via the ENTER key.
The message USE ARROWS/ENTER indicates that module
numbers or other variables can be changed with the
arrows prior to entering the activity with the ENTER key.
The message PRESENT CONFIG is used in system
responses during CHECK activities. Variables displayed
as PRESENT CONFIG can be changed via the CHANGE
mode.
Positive response messages such as SYSTEM RESET
COMPLETE are displayed for 1.5 seconds to confirm that
the activity has been completed.
Activity names are displayed bracketed by "<" and ">"
signs.
Normal operation is the condition where the change and
calibrate light is off and the display cycles continuously
between all active module numbers.
If the ENTER key is pressed once during normal operation
the display locks onto the current module number and can
be advanced using the UP and DOWN arrow keys. When
the display is locked onto one module number the gas type
and units display is shown in round parenthesis “( )”.
If any module is force calibrated, the gas type and units
display for that module number is shown in square
parenthesis “[ ]”.
The message USE ARROWS/ENTER indicates that the
arrows can be used to change the module number or other
data on the second line and the ENTER can be used to
access the selected activity or module number.
Successive presses of any one of the four activity keys
will cycle through each option available and will return
the system to the normal operating mode..
When any activity key cycle has been started and not
completed the remaining activity keys are disabled except
that the RESET key can be used to return the system to
normal OPERATE mode.
When the system is in the CHANGE mode the CALIBRATE
OR CHANGE light is ON.
