Features
Speed control
-
These motors can be
controlled by either the
dial on the motor or
a 0-10 VDC signal for
remote control.
Soft start
– All motors feature soft-start technology
which eliminates inrush current at start-up. The motors
will reliably start at any speed setting. There will be a
four second delay between the application of power and
the motor starting.
Overload protection
– If the motor becomes
overloaded, it will automatically reduce its speed until it
is no longer overloaded. This prevents the motor from
operating in the "service factor" should the motor be
misapplied.
Locked rotor protection
– If the motor ever encounters
a locked-rotor scenario, the motor will automatically
shut itself down. It will try to restart up to 3 times, and if
after the 3rd time the motor will still not rotate, the motor
will not attempt to start again until power is cycled.
Thermal protection
– The motors have electronic
thermal protection. If the motor temperature exceeds its
limits, it will slow itself down until the temperatures have
dropped.
Operation and Wiring
These motors can be controlled by either the dial on
the motor or a 0-10 VDC signal for remote control. The
motor will be supplied from the factory with the correct
accessory depending on what control option was
ordered.
Dial on Motor -
Turn the dial with your fingers to adjust.
To increase the speed, rotate the dial clockwise. To
decrease the speed, rotate the dial counter-clockwise.
Turning the dial full CCW will turn the motor off. A 16-pin
connector with two jumper wires must be installed for
the dial to function.
0-10 VDC Signal -
From 0-1.9V, the motor will be off,
and will operate within the 2-10V range. This motor
does not require 24V power for operation. For 0-10V
operation, a 16-pin connector with two wires connected
to pins 8 and 16 is required.
