When the correct password has been
entered the monitor will display the setup
screen.
Press the “3” key to enter System Setup.
System setup consists of two screens that
allow the user to change passwords,
change system flags, test the alarm circuits
and set the time and date. The user can
toggle from one screen to the other by
using the left and right arrow keys.
Key selections 1, 3 and 5 are used to:
change passwords, test the alarm relays
and program data trending. Refer to
Appendix A of manual for instructions to
change passwords. The alarm test function
is described in the Final Test section of this
manual. Refer to Appendix A of the manual
for instructions to program trending.
Press the “2” to enter the System Flags
screens. The system flag screen will
display
information
for
five
settings,
displayed on two screens. Press the ENT
key to move the cursor from one line to the
next, and press the left arrow key to move
from one line to the previous.
The autozero flag can be used to limit the
frequency of autozero cycles. It can be set
between 0 and 100. If a 0 is entered, the
monitor will enter an autozero cycle after
every area is sampled (this is the normal
default configuration). Increasing this
number will allow the monitor to skip the
autozero cycle if the raw measurement from
the IR-Bench has not changed significantly.
That is, if the raw signal varies by less than
plus or minus 10 millivolts, and the autozero
flag is set to 10, the monitor will not perform
an autozero cycle.
NOTE: This is
effectively reducing the extreme low-level
sensitivity of the monitor.
If this feature is
desired, set this flag by increasing it in
small steps, 1 or 2 digits at a time, until the
monitor stops autozeroing after every zone.
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.
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.
