the OA dampers will modulate

NOTE: CHECKOUT
functions bypass the normal
5-minute delay for compressor protection. Be sure to
allow for enough time to pass between tests so the
compressor is not damaged from extreme short-cycling.
MINIMUM POSITION NOTE:
Minimum position
setting has been preset to 10V which when connected
to MC4002 Lead/Lag Controller System will allow
economizer to drive wide open per emergency ventilation
strategy as detailed in MC4002 Instructions. This may
require resetting to a lower value per job specifications.

CHECKOUT:
from the main screen, press the
SCROLL (UP/DOWN) BUTTONS
to navigate through the
six (6) basic menu items to the
CHECKOUT
menu.
– Push the
SELECT (ENTER) BUTTON
to choose the

CHECKOUT
menu,
press the
SELECT (ENTER) BUTTON
to choose a
particular exercise,
“RUN?
”
will appear. Press the
SELECT (ENTER) BUTTON
again to activate this
exercise. After a short pause,
“IN PROGRESS”
will
appear as the test activates.
“DONE”
will display
after the test is complete. Press the
MENU UP
(EXIT) BUTTON
to end the test and/or turn off the
activated relay.
– For specific
CHECKOUT
level information, refer to
Table 5
.
NOTE:
Economizer assembly should be ready to
put into service. At any point during operation, in
economizer mode or idle, real-time information from
sensors and integral components can be accessed from
the
STATUS
menu.

STATUS:
from the main screen, press the
SCROLL
(UP/DOWN) BUTTONS
to navigate through the six (6)
basic menu items to the

information in real-time, there is no way to
change or otherwise alter the displayed criteria.
It is simply a window into the operation of the
economizer controller.
– For specific
STATUS
level information, refer to
Table 6
on page 18.
NOTE:
Upon power-up (or after power failure or low
voltage condition), the controller will begin a 5-minute
time delay before enabling mechanical cooling.
