Scaling for the Analog Output (AO2) point. To get the correct
output, the slope and intercept of this point must match the
point database of the room controller.
When EXH FLOW and FLOW STPT are different by more
than the AO2 DEADBAND, the AO2 FLOW SIG changes
from setpoint to actual flow.
Minimum voltage value for fume hood output range (typically
0.0V or 1.0V).
YES commands the controller to go through calibration
sequence for the air velocity transducers. YES is also
displayed when the calibration sequence is started
automatically. CAL AIR automatically returns to NO after the
calibration sequence is completed. Valid input: YES or NO.
The configuration setup code for the calibration sequence
options.
Time interval, in hours, between the calibration sequence
initiations if a timed calibration option is selected in CAL
SETUP.
The pressure that is applied to AVS1.
The time, in tenths of a second, between control loop
calculations.
The status code that indicates any errors detected during
controller power-up.
Factor used to filter out large changes in the value of FACE
VEL that is displayed at the ODP. This value is a percent that
is used to average a portion of the current average face
velocity with a portion of the previous average face velocity.
The value of this point is a percentage of the current average
face velocity. (Application 6740 uses EXH VOL.)
A change of value (COV) limit for the face velocity displayed
at the ODP. The display does not update unless the change
in face velocity exceeds this value.
When set to YES, the face velocity does not display at the
ODP.
Turns on all lights, prompts, and the audible alarm at the
ODP.
Toggles the display of the ODP from feet per minute to
meters per second. Toggling this point does not change the
displayed value at the portable operator's terminal.
The database point used to view and edit the internal Venturi
calibration data.
The database point used to view and edit the internal Venturi
calibration data.
The database point used to view and edit the internal Venturi
calibration data.
Determines when the flow PID will "coast" if near setpoint.
Determines when the flow PID will "coast" if near setpoint.
Remote initiation of the Emergency Purge functionality.
The controller does not use feedback to reposition the air
