Application Description
DO 7 47 6700 Spare digital output controls a 24 Vdc load with an ON or
OFF status.
AUTOZERO DO8 48 6740, 6741, 6742 Drives the Offboard Air Module(s) in order to calibrate the
flow sensor(s). Do not use or manually set this point.
DO 8 48 6700 Spare digital output controls a 24 Vdc load with an ON or
OFF status.
AI 3 49 6741, 6742 Optional input for External Face Area or Airflow sensor.
AI 3 49 6700, 6740 Optional input for Airflow sensor or spare analog input (0 –
10V or 4-20 mA).
AI 4 50 6741, 6742 Sash sensor 2 input or spare analog input (0 - 10V or 4-20
mA).
AI 4 50 6700,, 6740 Startup DI 4 (Point 56) or spare analog input (0 – 10V or 4-20
mA).
AI 5 51 6741, 6742 Sash sensor 1 input.
AI 5 51 6700, 6740 Spare analog input, 10K Ω.
VERT SASH1 52 6741, 6742 Current position, in inches (cm), of the vertical sash wired as
sash 1 at the controller board. If not physically wired to the
controller, this point may display as 'failed'.
VERT SASH2 53 6741, 6742 Current position, in inches (cm), of the vertical sash wired as
sash 2 at the controller board. If not physically wired to the
controller, this point may appear as 'failed'.
FACE AREA 54 6741, 6742 The open area, in square feet (SQM), of the fume hood face,
which includes the fixed area and accounts for the bypass
area.
CAL SASH POS 55 6741, 6742 User defined value used during calibration of the sash sensor
to describe the current position of the sash, in inches (cm).
CAL SASH LOC 56 6741, 6742 User defined value (MIN or MAX) used during the calibration
sequence to indicate if the minimum or maximum sash
position is being calibrated.
DI 4 56 6740 DI determines if DI 4 is used to change the STARTUP
MODE.
CAL SASH NUM 57 6741, 6742 The number of the sash being calibrated. Valid values: 1 to
5.
DMPR COMD 58 6740, 6741, 6742 The commanded position of the damper.
INVERT DO2 59 6740, 6741 Setting to NCLOSE allows the controller to operate industry
standard floating control actuators. Setting this point may
stop the failsafe operation from functioning.
AVS FAILMODE 60 6740, 6741, 6742 Indicates the desired position of the damper if the airflow
sensor(s) fail.
Valid values: CLOSED or OPEN.
EXH P GAIN 61 6740, 6741, 6742 The proportional gain value for the fume hood flow control
loop.
EXH I GAIN 62 6740, 6741, 6742 The integral gain value for the fume hood flow control loop.
EXH D GAIN 63 6740, 6741, 6742 The derivative gain value for the fume hood flow control loop.
FIXED AREA 64 6741, 6742 Open area of the fume hood, in square feet (SQM), that
remains the same regardless of sash position.
VERT WIDTH1 65 6741, 6742 Defines the overall width of the vertical sash wired to sash 1
