Analog Inputs and Outputs The analog inputs (voltage or current) are scaled by the Level 2, Output Limits, Min and Max Output Frequency parameter values.

Two analog inputs are available: analog input #1 (J4-1 and J4-2) and analog input #2

(J4-4 and J4-5) as shown in Figure 3-24. Either analog input #1 or #2 may be grounded provided the common mode range is not exceeded. Either analog input may be selected in the Level 1 INPUT block, Command Select parameter value. Analog input #1 is selected if parameter value “Potentiometer” is selected. Analog input #2 is selected if parameter value “0-10Volts, 0-5 Volts or 4-20mA” is selected.

Analog Input #1

The single ended analog input #1 is used when the controller is set to Standard 3 Wire,

(Single Ended)

Fan Pump 2 Wire, Fan Pump 3 Wire, Serial, Process Control, 3 SPD ANA 2Wire, 3 SPD

 

ANA 3Wire, EPOT-2 Wire or EPOT-3 Wire (not Keypad or 15 Speed).

 

The single ended analog input #1 can be used in one of three ways. Speed command

 

(Level 1 Input block, Command Select=Potentiometer). Process Feedback (Level 2

 

Process Control block, Process Feedback=Potentiometer). Setpoint Source (Level 2

 

Process Control block, Setpoint Source=Potentiometer).

 

When using Analog Input #1, the respective parameter must be set to

 

“POTENTIOMETER”.

 

Note: A potentiometer value of 5kW to 10kW, 0.5 watt may be used.

 

1.

Connect the wires from the 5KW pot at the J4 terminal strip. One end of the pot

 

 

is connected to J4-1 (analog ground) and the other end is connected to J4-3

 

 

(reference voltage).

 

2.

Connect the wiper of the pot to J4-2. The voltage across terminals J4-1 and

 

 

J4-2 is the speed command input.

Analog Input #2

Analog input #2 accepts a 0-5VDC, 0-10VDC or 4-20 mA command. The operating

(Differential)

mode is defined in the Level 1 Input block OPERATING MODE parameter.

Note: Analog Input #2 is used with Standard Run 3-Wire, Fan Pump 2 Wire, Fan

Pump 3 Wire, Process Control, 3 SPD ANA 2Wire, 3 SPD ANA 3Wire,

EPOT-2 Wire or EPOT-3 Wire (not Keypad, 15 Speed or Serial modes).

Note: Analog Input #2 can be connected for single ended operation by grounding

either of the inputs, provided the common mode voltage range is not exceeded. The common mode voltage can be measured with a voltmeter. Apply the maximum command voltage to analog input 2 (J4-4, 5). Measure the AC and DC voltage across J4-1 to J4-4. Add the AC and DC readings together. Measure the AC and DC voltage from J4-1 to J4-5. Add the AC and DC readings together.

If either of these measurement totals exceeds a total of ± 15 volts, then the common mode voltage range has been exceeded. If the common mode voltage range has been exceeded, the solution is either to change the command voltage source or isolate the command voltage with a commercially available signal isolator.
