Troubleshooting: Drive Motor Control Box Description
Series 2000 Treadmill
409110-004
Electrical Requirements
The two black wires that exit the side of the enclosure supply power to
the drive. The power source should be single phase, 208/240 VAC. If the
line voltage dips below 170 VAC or exceeds 264 VAC, the drive faults.
Maximum input current is 16A.
Fuses should be KTKR 20 only. Substituting a different fuse type may
cause a fire or safety hazard.
The orange wire from the side of the enclosure is connected to the sheet
metal enclosure and should be connected to the designated terminal on
the power terminal block. Do not connect this wire to the treadmill
frame which would cause a safety hazard.
The motor wires exit through the flexible conduit on the left side of the
enclosure. These wires carry the pulsed 320 V to the motor. Be sure to
observe proper phasing when connecting these wires. The drive will not
operate with incorrect phasing.
NOTE
If the motor is disconnected, do not let the
motor wires short to each other or any other
point. If it rotates, the motor will function as a
generator, and it may be damaged or cause
a shock hazard. The ground strap from the
flexible conduit should be connected to the
motor frame. Make sure this connection is
secure.
