Using the ACE
Diagnostic Display
t
The primary electronic controller controls most machine
functions. The controller determines what function is re-
quired for various input switches (i.e. seat sensor, key
switch, etc.) and energizes the outputs to actuate sole-
noids or relays for the requested machine function.
For the electronic controller to control the machine as
desired, each of the inputs, outputs must be connected
and functioning properly. The primary electronic control-
ler controls the functions of cutting units #1 through 5.
On the RM 6700-D, the secondary electronic controller
controls the functions of cutting units #6 and #7.
The Diagnostic ACE display is a tool to help the user
verify correct electrical functions of the inputs and out-
puts used and controlled by the electronic controllers.
Checking Interlock Switches
The purpose of the interlock switches is to prevent the
engine from cranking or starting unless the traction ped-
al is in NEUTRAL, the Enable/Disable switch is in DIS-
ABLE and the Lower Mow/Raise control is in the neutral
position. The engine will stop when the traction pedal is
depressed with operator off the seat. In addition, the en-
gine will stop if the traction pedal is depressed and the
parking brake is engaged.
The interlock switches are for the protection of
the operator and bystanders and to ensure cor-
rect operation of the machine. Do not bypass or
disconnect switches. Check operation of the
switches daily to make sure the interlock system
is operating properly. If a switch is defective, re-
place it before operating. Do not rely on safety
switches entirely - use common sense!
Check Input & Output Functions
1. Park machine on a level surface, lower the cutting
units, stop the engine, and engage the parking brake.
2. Open control panel cover.
A. For RM 6500-D: Locate wire harness with
Loop-back connector labeled #1 for electronic
controller.
Note: For checking optional TurfDefender leak de-
tector, see Leak Detector Operation and Checking
Leak Detector Operation in this section of this manu-
al.

CAUTION
1. Diagnostic ACE
Carefully unplug loop back connector from harness
connector.
Connect the Diagnostic ACE display connector to
the harness connector. RM 6500-D overlay decal
specific to the model and serial number of the unit
being tested must be placed on the diagnostic tool.
B. For RM-6700-D: Locate wire harness and con-
nectors labeled #1 (primary electronic controller) or
#2 (secondary electronic controller).
Note: For checking optional TurfDefender leak de-
tector, see Leak Detector Operation and Checking
Leak Detector Operation in this section of this manu-
al.
Carefully unplug loop-back connector from harness
connectors.
Connect the Diagnostic ACE display connector to
the correct harness connector. RM 6700-D overlay
decals specific to the model and serial number of the
unit being tested must be placed on the diagnostic
tool. Overlay decal #1 must be used when checking
primary controller (connector #1) and overlay decal
#2 must be used when checking secondary control-
ler (connector #2).
2. Turn the key switch to the ON position, but do not
start machine.
Note: The red text on the overlay decal refers to input
switches and the green text refers to outputs.
