warning
A poor electrical connection can overheat and cause
terminal and/or terminal board failures. Examine the
wiring harness quick- connect terminals carefully for
any signs of physical deterioration or loose fit to the
terminals on the motor terminal board.
Care must be taken to assure connections are made
to the proper terminals and adequate electrical clear-
ances are maintained.
warning
The control unit on the motor contains potentially
hazardous voltage.
caution
Wear safety glasses to inspect the equipment while
it is running, especially if cover plates are removed.
notice
• Voltage symbols vary among different multimeters and
may be displayed as
V AC
, AC, V, or a V beneath a wavy
line. Select the correct symbol and set the multimeter to the
voltage closest to the voltage you are measuring.
• Read all instructions thoroughly and be familiar with the
equipment before installing or working on it.
• The PerfectSpeed® motor is properly packaged for ship-
ment and storage and should be kept in a clean and dry
indoor area.
Overview
The interface board communicates with the motor control to
operate the motor in speed mode. The operating parameters
are programmed in the
eeprom
of the motor control, not the
PerfectSpeed® User Interface. On power up the interface board
extracts the operating parameters from the motor control.
Parameter categories include:
• Motor direction
• Motor mode of operation
• Motor output display
• Motor profile
PerfectSpeed® user interface box
The PerfectSpeed® operates in speed mode when connected to
the pump. You can adjust the demand of the motor manually
using the PerfectSpeed® User Interface. The motor information
displayed in the User Interface is outlined in
Table
1
. If the
motor encounters a problem, the User Interface displays a
corresponding error code. These are outlined in
Table
1
as well.
