- The Motor Speed Controller is used with blower motors with Hall effect tachometer sensors included to help facilitate blower speed control.
Вижагиҳо
There are two Motor Speed Controller options, the 240 V and the 480 V. Both controllers function the same, but are equipped with a different voltage power supply. See Figure 1, this page for details. The Motor Speed Controller controls speed based on the dip switch settings. The controller provides two speed modes, low and high speed. The two modes are controlled by 24 VAC control power inputs.
Огоҳӣ: The controller uses a phase control method to adjust the voltage supplied to the motor. Confirm with the motor manufacturer that the motor being controlled is acceptable for this type of operation. Motor type must be permanent split capacitor (PSC) or shaded pole and be equipped with a one pulse per revolution Hall effect tachometer sensor.
Танзимоти Гузариш
In Two Speed applications, the low speed is set by the sum of the rpm values for all switches that are in the open/off position. See Table 1, this page for dip switch settings.
| Дип Гузариш | RPM |
| 1 | 20 |
| 2 | 40 |
| 3 | 80 |
| 4 | 160 |
| 5 | 320 |
| 6 | 640 |
| 7 | 1280 |
| 8 | 2560 |
Ҷадвал 1: Dip Switch Settings
ШАРҲ: If the dip switch setting is outside of the 1000- 3400 rpm range, it is invalid and the fan will run at 100%.

Dip Switch Calculation
To determine the motor speed, calculate the sum of the values for all switches in the open/off position. For example, if switches 1 ,3 ,5, and 7 are open/off, the motor speed is 1700. See Figure 1, this page for details.

Ҷадвал 3: Motor Speed Controller 480 V Specifications
Ҳокимиятро назорат кунед
There are three 1/4 inch quick-connect tabs for 24 VAC control power signal connections. The W1 terminal is 24 VAC common and ground. The W2 terminal is the high speed input, and terminal W3 is the low speed input. If W2 is supplied with 24 VAC power and W3 is unpowered, the motor is will run at full speed. If W2 and W3 receive power, or if W3 receives power while W2 is unpowered, the motor speed will be controlled to the analog input voltage or the dip switch setting.
Line and Motor Connections
The L1 and L2 quick-connect terminals should be connected to a 240 V or 480 V power supply. The M1 and M2 terminals should be connected to the motor.
Монтаж
The Motor Speed Controller has a factory mounted aluminum base plate. The metal base plate helps the controller regulate temperature and facilitate proper heat dissipation.

Two Speed Wiring
In Two Speed Mode, when 24 VAC power is applied only to terminal W2, the motor will operate at high speed. If 24 VAC power is applied to terminal W3 (instead of, or in addition to, terminal W2), the motor will operate at a speed determined by the dip switch setting. See Figure 4, this page for wiring details.

Усулҳои амалиёт
Амалиёт
The Motor Speed Controller is used to control the speed of PSC or shaded-pole fan motors. The binary inputs are used to switch between High and Low Speed Modes. In High Speed Mode, the fan operates at 100%. In Low Speed Mode, the fan is controlled by the rpm setpoint determined by the dip switch setting. Fan speed is provided to the controller by a Hall effect tachometer in the motor. If the fan speed is above or below setpoint, the voltage supplied to the fan will be decreased or increased to maintain the fan speed setpoint.
Хомӯш
In Off Mode, there is no W2 or W3 input and the fan output is de-energized.
Реҷаи суръати баланд
In High Speed Mode, the W2 input is energized with 24 VAC power and the W3 input is de-energized. The fan runs at full speed. If the W2 and W3 inputs are both de-energized, the fan output will de-energize. If the W3 input is energized with 24 VAC power, the fan will switch to low speed.
Реҷаи суръати паст
- In Low Speed Mode, the fan will operate when the W3 input is energized or when the W2 and W3 inputs are energized with 24 VAC power.
- When the fan is powered on, it will run at high speed for 15 seconds before switching to low speed.
- The fan speed will be maintained at a speed determined by the dip switch settings.
- In Two Speed Mode, the fan rpms are labeled on the circuit board. The switch position should be set to OFF to add that position’s rpm value. For example, for 2560 rpm, positions 1-7 should be
set to ON and position 8 should be set to OFF. - If the W3 input is de-energized, the fan will switch to high speed operation.
- The fan output will de-energize if both W2 and W3 inputs are de-energized.
