INTRODUCTION
The DDM101 is an dual actuator accessory module used to support
fuel and exhaust temperature balancing adjustments to both banks of
the engine, enabling each bank to receive the same amount of fuel to
produce the same amount of power, safely.
This module is primarily installed with two actuators to support a
single engine with two independent diesel fuel injection pumps or two
gaseous throttle body actuators (ATB). It is controlled with a single
GAC electronic speed controller (ESD). Thermocouple sensors
are required to gather the exhaust information used to balance the
engine.
Recommended electronic speed controllers are listed in Table 1.
Recommended actuators are listed in Table 2.

- Page 2 (ESD) and references the ESD5111 terminal callouts. When mounting the DDM101 attach it to a vertical surface to prevent any moisture from collecting on the circuit board. The normal precautions outlined in the related ESD manual should be followed for the DDM101 as well.
- Page 3 DDM101 INSTAllATION (CONTINUED) The DDM101 works with the specified ESD models. Placement should allow for wiring between both controllers as shown here. The com- plete wiring diagram in the Wiring section of this guide shows all the wiring options. The following diagram shows the most common setup.
- Page 4 Dry fit the sensor. Ensure the tip of the probe is well within the outlet exhaust flow. Apply thread sealant to the sensor. Mount the sensor using a NPT fitting. Thread the sensor finger tight plus two full turns. DDM101 Dual Driver Module 6-2020-A4 PIB4134 Governors America Corp. © 2020 Copyright All Rights Reserved...
- Page 5 WIRING (CONTINUED) The DDM101 works in tandem with a speed control unit. The following wiring diagram and specific wiring sections detail the DDM101 capabilities. Wiring details use the ESD5111 as the basis for terminal callouts. Check your speed controller wiring for confirmation of terminal.
- Page 6 TO AN Esd When connecting an ESD to the DDM101 ensure the actuator voltage driver type uses a PWM output and not a current driver output. In normal actuator usage with a GAC ESD one side of the actuator is typically at near ground level voltage.
- Page 7 WIRING (CONTINUED) POsITION sENsOR WIRING GENERAl INFORMATION Each position sensor cable should be three-wire shielded type with the shields connected only to the case on the DDM101.

Page 8: Engine Adjustments
The SPEED and GAIN adjustment on the ESD and the GAIN [ACT 1 and ACT 2] adjustments on the DDM101 can have some interaction. It is possible to turn one up and the other down and get similar results. The GAIN adjustments on the DDM101 must not be turned to low or speed control performance may suffer. - Page 9 ENGINE ADjUSTMENTS (CONTINUED) GAIN AdJUsTMENT With the engine running at rated speed, adjust gain and stability (PID) at the ESD or the DDM101 for optimum performance. Adjusting the ESD, see your speed control unit’s manual for details on the following: •...
- Page 10 Exhaust temperature is, however, a good indication of balance and the exhaust temperature control loop will actively trim the system. With two industrial rated Type K type thermocouples installed in the exhaust pipe of each bank the DDM101 can measure and track two exhaust temperatures.
