SR115 115/230 Volt Speed Reduction Unit
Rev: 9/19/09
Application:
The SR115 is a Speed Reduction Control designed to reduce the motor speed by 50%. The SR115 is specifically
designed for 115 Volt and 230 Universal ('Rectified DC motors); up to 10 Amps. The SR115 is a PWM control to
assure slow speed motor torque.

Motor
Motor wires #1, #2, #3, #4 are not used when
using the SR115 Speed Control. The
AC to DC rectifier function is integrated in the
speed reducer and these four wires are not
required. There is no voltage or current in these
4 wires when the motor, or speed control, is
operating. You may insulate these with
electrical tape and secure these wires so they
do not hinder the reel drive mechansim.
You must use a Double Pole / Single Thow
momentary pushbutton switch. When the
pushbutton is pressed, the Orange wire makes
connection with the motor wire providing 115
Volt DC to the motor and the Yellow (5V signal)
wire tells the controller to soft start the motor.
When the pushbutton is released, the Orange
wire is disconnected from the motor wire
allowing the reel to turn freely and the Yellow
disconnect on the Yellow wire tells the controller
to turn off the motor. If you do not want to wire
up a DPST switch, you must puruchase the
MD115S, with the on/off motor switching
function.
Circuit Protection - The installer must
provide the 12 AWG feed lines (hot leg
and neutral), protected by a 15 Amp
circuit breaker in the electrical service
panel. Do not use a ground fault breaker
for the motor controller circuit protection.
Warranty:
The control must be sent in for analysis to determine if the 1 year is valid. Reason for falures have been not wiring per the directions
and not adequate circuit breaker protection. We will repair the equipment without charge for materials and labor if it is determined to be a
workmanship problem or faulty material. If it is determined that the cause of fail was due to mis-wiring, or not wiring per these instructions,
we will provide a repair quote prior to repairing.
