Part Two
The IN# NIGHT SETB item reads the current state of a setback contact
input. This item will only be displayed when the corresponding INPUT
SEL # item has been set to NIGHT SETB under the CONFIGURE menu.
When this item is entered, the display will indicate either OPEN or
CLOSED. If the display indicates CLOSED, the controller has been put
into setback mode through the contact input. If the display indicates
OPEN, the controller has not been put into setback mode through the
contact input. However, the controller may be in setback mode if it has
been initiated through the keypad or via network communications.
NOTE: IN# NIGHT SETB is a read-only item.
The IN1 SASH POS VER item is used to read the input from the sash
position potentiometer. This item will only be displayed when the INPUT
SEL 1 item has been set to SASH POS VERT under the CONFIGURE
menu. When this item is entered, a voltage is indicated on the display.
The exact number displayed is relatively unimportant. More important is
that as the fume hood sash is moved, the voltage on the display should
also change, which indicates the sash position potentiometer is working
correctly.
NOTE: IN1 SASH POS VER is a read-only item.
The SHOW SASH%OPEN item is used to display the current measured
or calculated sash open percentage.
The SHOW SASH AREA item is used to display the current measured
or calculated sash open area in ft
2
(or m
2
).
Enter the SELF TEST menu item to verify DIM electronics are
functioning correctly. During the self test, the display will show the model
number and software revision of the controller. At the end of the self test,
the display will show NO ERRORS if all DIM electronics are good. If unit
displays an FRAM error at the end of the test, settings may be
corrupted. Check all menu items to determine cause of DATA ERROR.
If unit displays a CALIB error at the end of the test, calibration may have
been lost. Verify face velocity, sash sensor and/or flow calibration.
The RESET SETTINGS item is used to change all settings to factory
default. RESET SETTINGS will not affect calibration.
WARNING: Unconfiguring the unit with the RESET SETTINGS item
may change critical settings including control set point.
Always reconfigure unit after using RESET SETTINGS
item.
The RESET ALL CALIBS item is used to clear field calibration data.
WARNING: Clearing field calibration data with the
RESET ALL CALIBS item may result in incorrect
calibration and/or loss of containment. Always recalibrate
unit after using RESET ALL CALIBS item.
