Introduction
ACETM is an acronym for Automated Control Electronics. The “ACE System” is a machine control system
which is currently used on the Groundsmaster‚ 580-D, Reelmaster‚ 5000/6000 series fairway mowers
and Greensmaster‚ 3200 (gasoline only). All of these machines operate under the same concepts and
TM
utilize common diagnostic procedures. The ACE System is also used to control the TurfDefender
hydraulic leak detection system and Sonic Boom accessory for spray systems.

The ACE System was developed for several reasons:
∑

∑
Ease of operation and safety.
Reduces mechanical linkage requirements (and adjustments).
Reduces electrical wiring and components.
Reliability.
Allows ClipAceTM function on some fairway mowers (matches reel speed to traction speed).
Common manufacturing and servicing capabilities.
The heart of the ACE system is an electronic control unit (ECU). This provides us with
several advantages:
∑

∑
Simplified diagnostic procedures.
Software upgrades.
Operational characteristics can be customized easily.
Expandable system.
The “ACE System” includes two sub-systems:
∑
∑
Electrical system.
Hydraulic system.
The simplest explanation of the ACE system is that it utilizes an electrical system to control and activate
the hydraulic system of a machine. This is extremely important to understand the interaction of these two
systems because an ELECTRICAL PROBLEM CAN CAUSE A HYDRAULIC CONTROL VALVE TO
MALFUNCTION, but a HYDRAULIC PROBLEM CAN NOT CAUSE AN ELECTRICAL MALFUNCTION.
If something goes wrong on the machine, the first step in diagnosis is to determine if the problem is
electrical or hydraulic. Because the controller provides us with enhanced diagnostic capabilities, electrical
system tests can be performed easily and quickly.
Note: If a machine equipped with ACE malfunctions, always check the electrical system first, before
looking for possible hydraulic problems.
Follow proper troubleshooting procedures. Talk to the operator. By asking the correct questions, the
operator may actually tell you what is wrong. It could be as simple as not understanding how the system
operates (example: Reel Control lamp illuminates while mowing). Some questions to ask the operator:
∑
∑
Exactly what is happening?
Was (or is) the Diagnostic Lamp flashing?
NO = First use the Diagnostic ACE Display tool to check INPUTS, then perform hydraulic tests.
YES =Use Diagnostic ACE Display tool to check OUTPUTS.
Is the problem repeatable? or is it intermittent?
∑
Note: The controller can store output fault information which can be retrieved with the Diagnostic ACE
Display tool. This can be very helpful when diagnosing intermittent problems. This feature requires a
controller software upgrade on machines built prior to the 1997 model year (S/N before 70001).
