Product Safety Warnings

WARNING: EMP cannot anticipate every possible circumstance that might involve a potential hazard.

The safety messages in this document, in related manuals, and on the product are therefore not all inclusive.

If a tool, procedure, work method, or operating technique that is not specifically recommended by EMP is

used, you must satisfy yourself that it is safe for you and for others. You should ensure that the product will

not be damaged or be made unsafe by the operation, maintenance, or repair procedures that you choose.

WARNING: Ensure that all safety messages and information messages are read and understood before

installation, maintenance, or repairs are performed. It is important to use caution when service work is

performed. Knowledge of impacted systems and their operation are important before the removal or

disassembly of any component.

WARNING: Make sure the equipment cannot move before doing any work or diagnostic procedures on

the EMP component, system, or vehicle.

WARNING: When working near electric components, ensure they cannot activate unexpectedly.

Remove power or utilize lock out switches.

WARNING: Use extreme caution when working on systems under pressure (i.e. coolant, hydraulic

fluids, air, fire suppression, etc.).

WARNING: Make sure the work area is ventilated and well lit.

WARNING: Make sure charged fire extinguishers are in the work area.

WARNING: Reinstall all safety guards, shields and covers.

WARNING: Make sure all tools, parts and service equipment are removed from the work area.

WARNING: Ensure that all system power and ground connection points are torqued to EMP and/or

OEM specifications to prevent system damage. Failure to follow specified torque requirements can result in

loose connections which can damage electronic components and will void EMP warranty.

FIL11 Fans and μTMC System Controller

The fans and system controller are powered by the 12V or 24V electrical system. The system will consume a

maximum of 100 amps at full cooling potential. The fans and system controller receive power through the red

positive and black negative stud located on the system. The ignition enable is a 9–32V switched power source

sent from the chassis or a PLC to initiate operation of fans and system controller. Current consumption is related

to fan speed and in some applications the maximum fan speed may be restricted due to lower heat rejection

requirements. In these applications maximum current consumption will be much less. Each of the fans and the

system controller is protected by a 30A fuse. The TK3/TK4 also contains a 3-pin connector for interfacing with a

PC based service tool via EMP-Link.

Each of the FIL11 fans on the TK3/TK4 system is powered by an internal controller. The primary function of

these controllers is to control fan speed and direction as commanded via EMP-Link by the μTMC system

controller. If one or more FIL11 controllers lose communications on the EMP-Link bus when the ignition enable

is at rated voltage it will go to a default speed until the communication problem is corrected. Each of the FIL11

fans are identical and are interchangeable however they each have a unique EMP-Link address that is set by

resistors within the wiring harness. These EMP-Link addresses allow the FIL11 fans to report status information

back to the μTMC system controller for enhanced diagnostics.

The μTMC commands fan speed by referencing the inputs from the coolant and air temperature thermistors.

When either or both of the thermistors report a temperature above the programmed thresholds, the μTMC

controller will command the appropriate fans to a speed based on the set points for the coolant and the air.

Diagnostic Lamp

The diagnostic lamp will blink out active diagnostic codes. Active diagnostic codes indicate an abnormal condition

that persists over time. See Troubleshooting for information about reading diagnostic codes from the cooling

system.

Explanation of Function

Service Tool Interface

1. Remove the sealed cap from the 3-pin service tool connector.

2. Insert the 3-pin mating connector from the EMP-Link DLA harness.

3. Apply the enable signal to the system.

4. Follow the instructions for service tool installation and operation. This tool can be used for monitoring data,

viewing diagnostic information, downloading new calibrations, and downloading history data.

5. When finished, unplug the DLA harness and re-install the sealed cap.

NOTE: EMP Service Tool Harness and data link adapter system is part number 7500038005

CAUTION: The sealed cap must be installed after using the service tool interface to prevent moisture

intrusion into the harness.

Installation

Mounting Hole Locations

Power and Ground Stud Assembly

CAUTION: Ensure that all system power and ground connection points are torqued to EMP

specifications to prevent system damage. Failure to follow specified torque requirements at any point of the

vehicle system power and ground can result in loose connections which can damage electronic components

on the cooling system and will void EMP warranty.

NOTE: Older systems may have an additional nut on the stud assemblies. Reference the decal label on your

system for details.

Minimum Coolant Quality Requirements

To protect your heat exchangers from damage or blockages, all coolant should be maintained to meet the

requirements of Cummins Service Bulletin #3666132-07 Cummins Coolant Requirements and Maintenance (or

more recent revisions). If your system is cooling an engine other than a Cummins engine, follow your engine

manufacturer’s guidelines, but ensure that you are using an antifreeze with system protection for aluminum

components. The Cummins bulletin is freely available on the internet.
