1. Introduction
The Pro-360 is an advanced digital PWM motor controller for currents up to 360A.
It uses a specialist microprocessor to control a full H-bridge design that does not
require relays for reversing. The display provides key information to the operator,
and can be mounted separately to the controller if required. It has a full range of
features and is very easy to configure if required.
2. Do's and Don’ts
Warning –the Pro-360 does not have reverse polarity protection.
Connecting the battery wires incorrectly WILL destroy the controller.
Do
•Do read the instructions fully
before installing.
•Do take care to connect the
battery wires with the correct
polarity.
•Do fit a motor suppression
capacitor, and ferrite rings.
•Do twist the motor wires
together if possible.
•Do call 4QD if you are
uncertain about something.
Do not
•Do not allow water to get onto
the circuit boards.

3. Getting Started
•Remove the four screws that hold the cover to the end plates and lift off the
cover.
•The Pro-360 is supplied with the keypad and / or display cables not
connected to their sockets. These should be plugged in once the Pro-360
has been fixed in position, the control and power connections made, and you
are ready to start operation.

4. Control Connections
The control input sockets are shown below.
The main control input and brake should be wired as shown below [they are
compatible with Pro-120/150 and DNO/VTX installations].

5. Simple wiring diagram
This diagram shows the basic connections needed to get the Pro-360 running.

6. Auxiliary Input 1
Has the following functions.
A -Deadman’s handle. There are 2 modes of deadman operation. In “std” if this
pin is connected to Gnd then the Pro-360 will follow the active profile ramp
down to zero, it will ramp up again when Gnd is removed. In “safe” this pin
must be connected to Gnd for operation to start.
B -Alternate profile. If this pin is connected to Gnd the Pro-360 will start up in
the alternate profile defined in the profile that was operating without the Gnd
present. This allows easy switching between any two profiles.
C -Limit 1. If this pin is connected to Gnd then the Pro-360 will invoke the
behavior defined for this limit. This will be available in version 2.4.
D -Emergency stop. If this pin is connected to Gnd then the Pro-360 will stop
immediately. It will not start up again until the Gnd is removed, and the ignition
has been turned off / on.
7. Auxiliary Input 2
Has the following functions.
C - Speed. This pin can be used with our speed sensor kit [part number SEN-SPD]
for top speed limiting. The sensor is powered by the BEC supply and delivers a 5V
pulse proportional to the speed of the shaft that the magnet is attached to.

8. Thermistor input
Can be used to connect 1 or 2 sensors to monitor external temperatures.
Sensor X is connected to C and D, Sensor Y to A and B.
Once the sensors have been installed they must be enabled in the profile menu.
9. Radio Control Input and BEC
The Pro-360 will accept a standard hobbyist radio control servo signal directly
from a receiver. The receiver should be connected to pins B, C, and D. Pin D is
linked to pin A by Lk1, this can be removed if a 4 wire radio connection is
required.
The Pro-360 is pre-programmed to work with the majority of radio receivers.
Profiles 7 and 8 are configured for RC single ended and RC joystick use.
Depending on your radio system you may need to use the RC learn function to
properly match the Pro-360 to your receiver output.
The RDO port can act as a BEC for currents up to 1A. Pin B of the adjacent BEC
port can be used in parallel to increase this to 2A if required.
Sensors X and Y should be 4QD
part number SEN-TMP.

10. Power Connections
The power connections are M8 diameter threaded posts. The wire used should
be of a diameter appropriate for the load envisaged.
Battery Wiring
Keep the battery wiring as short as possible to reduce the load on the main
capacitors.
Motor Wiring
To reduce electrical noise the motor wires should be kept close to each other and
twisted together if possible. A 10nF 100V disc ceramic motor suppression
capacitor should be fitted across the brushes of the motor. Ferrite rings should be
fitted on the motor wires. See the knowledgebase on our website for more
information on noise suppression.
If the motor rotates in the wrong direction, swap over the M+ and M- wires.
Battery Circuit Breaker
A circuit breaker or fuse should be fitted in the battery wiring. The rating should
be above that of the motors normal operating current.
A battery isolator switch should also be fitted to provide an emergency
disconnection capability. In some applications such an isolator is a legal
requirement.
Contactor
The Pro-360 has provision to drive a failsafe contactor which can provide an
emergency disconnection in the event of a controller failure. Details of how to
implement this feature are in the knowledgebase on our website.

11. Display
The Pro-360 has a 2 line display to display useful information during operation
and programming.
During operation the display will show information in this format:
Volts = battery voltage.
Duty cycle = % of battery voltage being applied to the motor [- = reverse].
Motor current = instantaneous motor current in amps.
Profile = profile currently selected [suffix R indicates reverse].
Temp = temperature in ‘C. Prefix C denotes controller temp, prefix X / Y denotes
sensor X / Y temp. X and Y only displayed if switched on in software.
Battery current = average current being drawn from the battery in amps. Note the
difference between this and motor current.
The display also shows any alert or fault information.
A display adaptor board is available that allows the display and / or keypad to be
mounted remotely from the Pro-360.
12. Programming
The Pro-360 has 15 profiles, 14 of which can be edited to suit the user. Each
profile has a number of settings which control various aspects of the controller’s
behavior. We have configured the first 9 profiles with values that are a good
starting point for the most popular applications, full details are in the table at the
end of the manual.
It is not possible to make changes to profile 01, to save changes you must first
select another profile.
To edit the settings the SEL button should be held down while turning on the
ignition, you can then navigate through the options and settings as shown in the
menu structure below. Remember to use the menu option to save changes.
