Product Overview
The Danfoss Transit Mixer Controller (TMC) is designed to control the drum functions of concrete
transit mixers. The TMC is shipped from the factory with ready-to-use transit mixer control software
installed. TMC software allows OEMS to optimize the performance of their machines by adjusting
tuning parameters using the PLUS+1 Service Tool. CAN bus communication technology allows
multiple TMCs to be installed on a transit mixer providing OEMs with a convenient and cost effective
way to provide cabin and remote control.
Features y TMC controllers are designed to survive the demanding transit mixer environment by providing
Ingress Protection IP 69K for front of panel and IP 67 for back of panel.
y TMC mechanical design provides a compact hardware footprint minimizing machine space
requirements.
y A Deutsch® sealed connector is molded into the TMC housing.
y A non-contacting rotary dial and switch on the front of the TMC allows reliable control of drum
speed and direction for mixer charge and discharge functions.
y Hardware configuration pins allow the TMC to interface with Danfoss and competitor hydraulic
systems.
y TMC software parameters and control features are easily accessed and changed using the PLUS+1
Service Tool.
y CAN bus communication allows up to five TMC controllers to be installed on a vehicle allowing
both cabin and remote control. J1939 CAN message protocol allows the TMC to read engine
variables and control the engine throttle.
y 9 to 36 Vdc power supply.
y CE compliant.

Wiring Recommendations y All wires must be protected from mechanical abuse. Wires should be run in flexible metal or plastic
conduits.
y Use 85˚ C [185˚ F] wire with abrasion resistant insulation. 105˚ C [221˚ F] wire should be considered
near hot surfaces.
y Use a wire size that is appropriate for the module connector.
y Separate high current wires such as solenoids, lights, alternators or fuel pumps from sensor and
other noise-sensitive input wires.
y Run wires along the inside of, or close to, metal machine surfaces where possible. This simulates a
shield which will minimize the effects of EMI/RFI radiation.
y Do not run wires near sharp metal corners. Consider running wires through a grommet when
rounding a corner.
y Do not run wires near hot machine members.
y Provide strain relief for all wires.
y Avoid running wires near moving or vibrating components.
y Avoid long, unsupported wire spans.
y All analog sensors should be powered by the sensor power source from the PLUS+1 Controller.
Sensor rounds should be returned to the machine control system
common ground.
y Sensor lines should be twisted about one turn every 10 cm (4 in).
y It is better to use wire harness anchors that will allow wires to float with respect to the machine
rather than rigid anchors.
y All machine electronic modules should be grounded to a dedicated control system ground that
consists of a conductor of sufficient size that is connected to the
battery (-).
y If a CAN shield is used, the shield must be grounded to the machine control system ground and the
CAN shield pin on the TMC controller.

TMC Software
Overview
Operation
Definitions
Cabin Station
One TMC controller on the machine is designated as the cabin station. Machine inputs and outputs
(motor speed PPU, configuration, charge and discharge outputs, and
CAN bus) are connected to the cabin station controller’s connector pins.
Remote Station
Up to four remote stations can be installed on a vehicle. Remote stations are only connected to the
vehicle’s CAN bus and power—other connector input and output pins are not used.
LED Indicator
The TMC station status is provided to the operator by a dual color (amber/red) LED located to the
right of the yellow control button, see Unit Dimensions, page 6.
TMC software controls the operation of a transit mixer drum by reading inputs from the TMC
controller’s input pins, CAN bus, operator control dial and operator switch, and by providing control
outputs to the TMC controller’s output pins and CAN bus.
The TMC software uses drum motor and engine speed to provide control inputs to the proportional
integral derivative controller (PID controller) algorithm controlling drum motor speed. Engine speed
is also controlled by the software when the vehicle is in work mode.
The TMC controller has two digital input configuration pins, allowing up to 4 sets of parameters to be
stored in the memory of the controller. This feature allows OEMs the flexibility to use the TMC
controller with hydraulic systems from different suppliers.
TMC Station Status
Indication Status
LED not illuminated Another TMC station is active
Blinking amber LED No TMC station is active
Solid amber LED The TMC station is active
Blinking red LED Error condition. See Error Codes, page 12, for error blink code information.
Active Station
The active TMC is the controller receiving operator inputs and sending outputs to the vehicle.
Activate Function
Each time a vehicle’s engine is started, one TMC station must be activated. To activate a specific TMC,
that TMC’s rotary dial must be in the neutral (center) position and the yellow TMC control button must
be pressed for two seconds.
Overtaking Control Function
This function transfers operator control from one TMC on the machine to another if more than one
TMC is installed on a vehicle. To make a specific TMC active, that TMC’s rotary dial must be in the
neutral (center) position and the yellow TMC control button must be pressed for two seconds.
Technical Information Transit Mixer Controller (TMC)
11061324 • Rev CA • Sep 201312
Charge Function
Transit mixer charge functionality is enabled from an activated TMC by pushing the yellow TMC
control button and turning the rotary dial to the right (clockwise). Drum speed and engine RPM are
functions of the rotary dial position.
Discharge Function
Transit mixer discharge functionality is enabled from an activated TMC by pushing the yellow TMC
control button and turning the rotary dial to the left (counterclockwise). Drum speed and engine RPM
are functions of the rotary dial position.
The vehicle parking brake must be engaged to enable the discharge function.
Limp Home Function
If the cabin station TMC looses motor speed (PPU) input, the drum speed PID algorithm will be reset
and drum speed will be directly controlled from the rotary dial without any feedback compensation
for changes in engine speed and other disturbances.
Error Codes
If the TMC application software detects an error condition, the output signal to the drum motor will
be set to zero and an error blink code will be indicated by a red color LED (to the right of the TMC’s
rotary dial).

System Installation
System Set-up 1. Connect the Cabin Station TMC input and output pins to the vehicle’s wiring harness.
Be sure to have one of the two configuration pins connected, reference TMC Configuration Options,
page 7. The Cabin Station TMC’s CAN bus address will automatically be assigned by the software
when power is applied to the controller.
2. Sequentially connect Remote Station TMCs to the vehicle CAN bus.
Reboot the system so that the new Remote Station TMC can claim a valid node ID. The vehicle TMC
system must be rebooted any time a new Remote Station is connected. Failure to reboot may
cause TMC CAN bus address conflicts.
3. Adjust TMC application tuning parameters.
The PLUS+1 Service Tool is used to access and change TMC application software tuning
parameters, reference PLUS+1 GUIDE Service Tool User Manual, 520L0899.
PLUS+1 GUIDE TMC P1D file is required in order to access tuning parameters.
The P1D file allows access to the following:
• Limit drum speed
• TMC system overview
• Rotary switch calibration
• Rotary switch time ramp
• Manufacture code
• System 0 to 3 (Shows up to TMC tuning parameters sets—one for up to four configuration input
pin settings)
• PID feed-forward parameters
• PID P parameters
• PID algorithm parameters
• Engine RPM request profile
• Output soft ramp
• All parameter summary
