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.
