“ENT” key again to display the third
system flag screen.
The DELAY FLAGS are used to
implement an additional time delay,
in minutes before energizing the
respective alarm relays. This time
delay is similar to the LEAK WAIT,
except that the user is able to create
a time definite delay, rather than the
ppm level defined LEAK WAIT delay.
The factory default setting is 0 for
each delay.
Press the “ENT” key to move the
cursor to the next entry. Once the
DELAY entries have been viewed,
press the “ENT” key to move the
cursor to the LATCH FLAG. The
LATCH FLAG is used to determine if
the LOW and MAIN alarms are self-
resetting or are latched. If the
LATCH FLAG is set to 0, the alarms
will function as a conventional
latching alarm. If the LATCH Flag is
set to 1, the LOW and MAIN alarms
will function as self-resetting alarms.
The HIGH alarm will always be a
latching alarm.
NOTE: The ASHRAE-15 standard
specifies that an alarm relay must be
latched, but that if more than one
alarm level is provided, the additional
alarms may be self-resetting. Care
must be used when implementing
this feature, as the alarm level that
corresponds to the ASHRAE-15
required alarm MUST be a latching
alarm. If there are any questions
regarding the correct implementation
of
this
feature,
call
SenTech
technical support.
Press the “ENT” key to move the
cursor to the next entry. When all
entries have been viewed, press the
“ENT” key again to return to the
previous menu. The monitor should
again display the system setup
menu.
Press the right arrow ”->” key to
access the second system setup
screen.
Press the “4” key to set the date and
time. The program time/date
screens allows the user to set the
day of the week, hour, minute,
month, day, and year for the real
time clock (RTC) in the controller.
Entering information, or pressing the
“ENT” key will move the cursor down
to the next entry.
Note that the RTC operates on a 24-
hour clock. For example to enter 2
