WARNING

When wiring the instrument, you must follow industry standard practices for control and protection against electrostatic discharge (ESD). Failure to exercise good ESD practices may cause damage to the controller.

1. Mount the controller in the vertical plane using four #8-32 screws. Open the front cover by unscrewing the two captive thumb screws to gain access to the four mounting locations pictured at right.

Note: Mount the Sure-Aire controller within 75 feet of the termination plate on the fan.

2. Use 1/4-inch nylon tubing to connect the corresponding high and low, 1/4-inch quick connect, pressure ports of the Sure-Aire controller to the high and low pressure ports of the termination plate on the fan.

3. Remove terminal block TB1 and perform wiring for the pins listed below. For liquid tight applications, use only 1/2-inch liquid tight conduit.

Terminal Block TB1: Input Power

Pin 1 = Line Pin 2 = Neutral Pin 3 = Earth Ground

4. Provide power to the controller to turn it on.

5. Select the desired Output Signal of the controller for the Building Automation System. Use the touch screen to select the 4-20 mA or 2-10 Vdc output signal via the controller’s setup menu. (Refer to

Display Setting Options and Setup section, Output Signal, pages 3 and 4).

6. Wire TB2 appropriately for the selected Output Signal in Step 5.

Terminal Block TB2: Transmitter/Temperature

Sensor

Pin 1 = 4-20 mA or 2-10 Vdc (+) (output)

Note: 4 to 20 mA requires a load resistor

Note: Signal isolator may be required when two or

more output signals share a common connection at the PLC/controller.

7. If temperature compensation is desired, mount the

provided temperature sensor in contact with the airstream. Wire the temperature sensor into TB2 and change Temperature Comp to “Yes” via the controller’s setup menu.

8. When the above steps are completed, make sure the

front cover is properly aligned to the housing and the two captive thumb screws are securely tightened.

NOTE

Apply a vacuum to the High Port and the 4-20 mA transmitter will track the span of the pressure range. i.e. The Sure-Aire controller with a pressure sensor of 0 - 41.51 in. W.C. installed, 4.00 mA = 0 in. W.C.,

20.00 mA = 41.52 in. W.C.

2.1 Validate the controller is setup for 4-20 mA output signal.

2.2 Validate the power is off on the DC power supply and the Sure-Aire controller.

2.3 Validate the multimeter is set to read mA DC.

2.4 Select a series Load Resistor between 200 and 900 ohms and install one end to TB2-1.

2.5 Interconnect the multimeter (+) probe to the other end of the load resistor.

2.6 Interconnect the multimeter (-) probe to TB2-2 to complete the current loop.

Temperature Sensor

Speciﬁcations

Interconnect the remote temperature sensor by connecting the temperature sensor to pins 4 and 5 of TB2. The Remote Temperature Sensor will adjust the air density value in the controller based on the sensor measurement when Temperature Compensation is set to ‘Yes’. This density compensation will affect the ﬂow rate accordingly. If Temperature Compensation is set to ‘No’, the air density value will be a function of standard air (70°F/21°C).
