Siemens 125-5033 owner manual Flow P Gain

Point Database

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.
