Reversing Motor Direction
Improperly connecting the exhaust fan and sieve motor starters will cause
them to rotate in the wrong direction. If the exhaust fan is rotating in the
wrong direction, powder will be blown out of the enclosure. If the sieve
rotates in the wrong direction, powder will back up in the accumulator. Use
the following procedures to check and correct, if necessary, fan and sieve
rotation.
Exhaust Fan Motor
1. Turn on system electrical power.
2. Start the exhaust fan motor.
3. Observe the direction of fan rotation. The fan should rotate in the
direction indicated by the yellow arrow on the front of the fan section.
The fan shaft should rotate clockwise when viewed from the sheave
(pulley) end (from above the fan). If the rotation is backward, go to the
next step.
WARNING:
Even with the disconnect switch in the off position, the
terminals at the top of the switch are still live. Do not touch them. Failure to
observe this warning could result in serious injury or death.
4. Shut off system electrical power. Open the electrical panel door and
reverse any two wires (L1, L2, or L3) connected to the fan motor starter
(M407). Close the electrical panel door.
5. Turn on electrical power. Start the fan and check the rotation direction.
Sieve Motor
1. Check your sieve manual for the proper motor rotation direction. If it is
rotating in the wrong direction, perform the next step.
WARNING:
Even with the disconnect switch in the off position, the
terminals at the top of the switch are still live. Do not touch them. Failure to
observe this warning could result in serious injury or death.
2. Shut off system electrical power. Open the electrical panel door.
Reverse any two wires (L1, L2, or L3) connected to the sieve motor
starter (M412). Close the electrical panel door.
3. Restore system electrical power. Start the sieve and check the rotation
direction.
