Password Flag:
The password flag
can be set to either 0 or 1. If a 1 is
entered, the monitor will require the
user to enter a password to perform
any functions of the monitor. This
feature is useful if the monitor is
installed in a public area, and
controlled access to the monitor is
needed. This flag is set to 0 by
default.
Horn Relay Flag:
Press the “ENT”
to move the cursor to the horn relay
flag. The horn relay flag can be set
to 0, 1, 2 or 3. This flag changes the
function of the horn relay to control
an audible alarm. With the flag set
to the 0, the horn relay will be
disabled. The monitor can be
programmed to allow the horn relay
to be de-energized while the monitor
is still in alarm. This feature is useful
when the user is troubleshooting an
alarm, and wants to work in silence.
Set the horn relay flag to 1 to
activate the horn relay when the
monitor is in LOW alarm. Set the
horn relay flag to 2 to activate the
horn relay when the monitor is in
MAIN alarm. Set the horn relay flag
to 3 to activate the horn relay when
the monitor is in HIGH alarm. This
flag is set to 2 by default.
Unit Number Flag:
The unit
number flag is used to identify the
monitor on a RS-485 network, if that
option has been purchased. This
flag is set to 1 by default.
Press the “ENT” key to move the
cursor to the next entry. When all
entries have been viewed, press the
“ENT” key again to display the
second system flag screen
Slope Flag:
The slope flag is used
for
circumstances
where
an
individual zone might be exposed to
large levels of refrigerant. This flag
will hold the monitor in its current
mode, whether it be autosample or
autozero, if the raw measurement
has not leveled off to a constant
measurement.
For instance, after an
extremely large level of refrigerant
has been measured, the monitor
might run in autozero longer than
expected if the measured level is still
falling.
Set this flag to the factory
default of 50 if no large levels are
expected. Set this flag lower if large
levels are expected.
TWA Alarm Flag:
Press the “ENT”
key to move the cursor to the TWA
ALARM flag. This flag is reserved
for future implementation of TWA
measurement. This flag should be
left at the factory default of 0.
Full Scale Flag:
Press the “ENT”
key to move the cursor to the FULL
SCALE flag. This flag is used to
adjust the full scale measurement for
the analog output. The factory
default is 1000, meaning that the 0-
10 volt analog output corresponds to
0-1000 ppm. This flag should be left
at the factory default unless a
custom measurement range has
AUTOZERO FLAG 0 -
PASSWORD FLAG 0
HORN RELAY FLAG 0
UNIT NUMBER FLAG 1
SLOPE FLAG 50 -
TWA ALARM 0
FULL SCALE 1000
TWA REFRESH 5
