OVERSPEED AND GOVERNOR TEST – MAGNETEK DRIVE
There are three tests to perform for the Overspeed and Governor test; Smartrise
Overspeed test, Governor Switch test and Governor Mechanical test. The
following procedures will test all three items.
Smartrise Controller Overspeed test:
1. Move the car to the top landing.
2. Go to the Magnetek Drive Menu Parameter. Adjust Drive A1:
a. Increase the “Contract Mtr Spd” by 50%:
Original Value: _________ x (1.5) = New Value: __________
3. Enter a Car Call in the Down Direction via MAIN MENU | DEBUG | ENTER CAR
CALLS.
4. The drive will run the motor at an increased speed causing it to run faster
than commanded resulting in an overspeed fault. If more speed is required
to achieve an overspeed condition, simply increase this parameter further.
Governor Electrical Switch test:
1. On the Smartrise controller, increase Contract speed by 150% (MAIN MENU
| SETUP | SPEEDS & SLOWDOWNS | CONTRACT SPEED).
Original Value: _________ x (1.5) = New Value: __________
NOTE: (Smartrise controllers cannot exceed 900FPM)
2. Set the S# speed by 50%. S# is your highest speed profile on SRU controller.
Original Value: _________ x (1.5) = New Value: __________
NOTE: (Smartrise controllers cannot exceed 900FPM)
3. Enter a Car Call in the Down Direction via MAIN MENU | DEBUG | ENTER CAR
CALLS.
4. At 125% of rated contract speed the Governor should trip causing the car to
E-Stop.
a. The Governor contact should open and the Machine Room Board Input
should NOT be on.
b. A mechanical reset might be needed if the Governor doesn’t reset
automatically.
