Address Descriptor Description
56 ODP STPT SW Indicates if the lower left button on the ODP has been pressed. This is a toggle
action digital input; when pressed, the controller changes between HI and LOW
flow setpoints.
57 RIGHT SW Indicates if the right auxiliary button on the ODP has been pressed. This is a
toggle action digital input; when pressed, the point is ON. If pressed again, the
point is OFF.
63 FLOW P GAIN The proportional gain value for the fume hood flow control loop.
64 FLOW I GAIN The integral gain value for the fume hood flow control loop.
66 FLOW D GAIN The derivative gain value for the fume hood flow control loop.
67 FLOW BIAS The bias, in percent, of the fume hood flow control loop.
68 CTRL LOOPOUT Control output of the flow loop. Range: -100% to 100%.
87 FLOW HI STPT The hi flow setpoint used in FLOW STPT.
89 HORN When this point is set to DISABLE, the audible alarm will not sound. All other
alarm functionality is still operational.
91 BLANK DSPLY When set to YES, the exhaust flow is not displayed at the ODP.
92 DO2 INVERTER Setting to NCLOSE allows the controller to operate industry standard floating
control actuators. Setting this point may stop the failsafe operation from
functioning.
93 ENG UNITS Toggles the display of the ODP from CFM to LPS. Toggling this point does not
change the displayed value at the portable operators terminal.
94 LAMP TEST Turns on all lights, prompts, and the audible alarm at the ODP.
96 ALARM TIME Time delay for the red and yellow alarm LEDs used to eliminate sudden changes
and false alarms. The exhaust flow must rise above any of the set limits (for
example, HI ALM LMT) for the amount of time specified at this point before the
ODP indicates an alarm condition.
97 DUCT AREA Area of the duct, in square feet (SQM), where the air velocity sensor is located.
98 LOOP TIME The time, in tenths of a second, between control loop calculations.
99 ERROR STATUS The status code that indicates any errors detected during controller power-up.
