VARIABLE SPEED CONTROL – SINGLE PHASE

Some single phase direct drive motor's running RPM can be adjustable with a variable speed control (please contact factory for more information). The speed control knob starts at off position, then high to low adjust range. At high speed, the speed control would allow the motor running at its maximum RPM. Dial the knob to the low side would let the speed control regulate the voltage on the motor to reduce the RPM.

A minimum speed adjustment is needed to limit the motor RPM range. Follow this procedure to set the minimum speed.

1. Motor must be in servicing status to allow the minimum speed setting. Motor would not slow down unless proper load is applied. Motor RPM would be changed under different system (static pressure).
2. Turn the main control knob to the lowest speed position.
3. Locate and adjust the minimum speed setting, it can be found on the control box itself.
4. Motor RPM range would be from full RPM to the RPM just set.

The lowest minimum voltage that may be applied to the motors is 65VAC. Running at lower voltage can cause premature failure to the motor.

VARIABLE FREQUENCY DRIVE – THREE PHASE

For 3 phase motors, a variable frequency drive (VFD) is required to adjust motor speed.

EC (Electronically Controlled) MOTOR SPEED CONTROL

EC motors are equipped with a control module that allows for accurate manual adjustment of motor speed. Motor speed range is from 300 to 1800rpm or maximum rpm for that model.

The control module features a 4 digit LED display that indicates % demand of full speed and motor speed in rpm. The display also indicates an error code message for minor diagnostics if required.

MESSAGE DISPLAYED...

Spd- followed by the instantaneous speed in rpm

dE- followed by S + demand in %
E1- No communications
E2- Under Voltage

Motor speed can be changed by adjusting the speed control pot located on the control module. A small screwdriver can be used to make the speed adjustment.

AC Supply - 115/208-230VAC

Power is connected to the motor and control module through the junction box and wiring harness provided.

Note: For 115VAC operation the blue jumper provided (taped to wire harness) must be inserted into motor power connector. See diagram.

Caution: Operating the motor at 208-230VAC with the jumper will cause significant damage to the motor.

Note: EC motors have a soft start feature. When the power is turned on the control module gathers information from the motor then begins the start up process. After a few seconds the motor will start to turn and reach full set speed in 10-15 seconds.

Remote Speed Control Option (please contact factory for further information)

UL762 RESTAURANT EXHAUST APPLICATION

All up-blast models are UL/cUL listed, they are capable to meet UL762 for Commercial Kitchen application:

• The National Fire Protection Association (NFPA) publication NFPA 96 is the primary source for this application. Also consult local authorities for all other applicable codes and guidelines before installation.
  • Exhaust fans used in kitchen ventilation applications must have external wiring. (Wiring must not be installed in the airstream).
• Installation must include a means for inspecting, cleaning and servicing the exhaust fan. (Curb hinge, grease collector and outdoor disconnect switches are available for purchase as accessories)
• No dampers can be used in the system.

PRE-START INSPECTION

1. Lock out all power sources.
2. Inspect all fasteners and set screws and tighten as required.
3. Inspect belt alignment and tension where applicable.
4. Confirm power source voltage and motor voltage are the same and that the motor is wired correctly.
5. Rotate the wheel to ensure that neither the fan blade nor the belts come into contact with the housing.
6. Inspect the fan and the ductwork to ensure they are free of debris.
7. Check to ensure that all guards and accessories are securely mounted.

START UP

Turn the fan on and inspect for the following:

1. Direction of rotation.
2. Improper motor amperage.
3. Excessive vibration.
4. Unusual noise.
5. Improper belt tension or alignment (only applicable on belt-drive unit).

If a problem is discovered shut off the fan and refer to the section on troubleshooting to discover the cause of the problem. The fan should be inspected after 30 minutes, 8 hours & 24 hours of operation to ensure all fasteners are tight and belts are properly tensioned and aligned.

MAINTENANCE

Disconnect and secure to the OFF position all electrical power to the fan prior to inspection or servicing. Failure to comply with this safety precaution could result in serious injury or death.

1. Ventilator should be checked at least once a year. For critical or severe applications a routine check every two to three months is suggested.
2. When moving or installing a belt, don't force the belt over the sheave. Loosen the motor mount so that the belt can be easily slipped over the sheave.
3. The belt, on belt driven units, should be removed and carefully checked for cracks, ply separation or irregular wear. A small irregularity in the contact surface of the belt will result in noisy operation. If any of these defects are apparent the belt should be replaced. At the same time check the sheaves for chips, dents or rough surfaces that could damage the belt.
4. The correct belt tension is important. Too tight a belt will result in excess bearing pressure, which can cause premature bearing failure and may cause the motor to overload. Too loose a belt will result in slippage, which will burn out belts. Proper belt deflection should be 1/64" (half way between sheave centers) for each inch of belt span when a force of approximately 5 lbs. is applied.
5. The belt alignment should be checked to be sure that the belt is running perpendicular to the rotating shafts. Motor and drive shafts must be parallel.
6. A periodic inspection of all fasteners should be carried out to ensure they have not loosened due to vibration. Particular attention should be paid to fasteners attaching the wheel to the shaft and those attaching the shaft to the bearing.
