Check electrical connections, input fuses and the
diagnostic light bulb to find the malfunction. Make
sure the connector is secured to the wire harness

DIAGNOSTIC ACE DISPLAY
The RM 5200-D is equipped with an electronic
controller that controls most machine functions. For
the electronic controller function correctly, each of
the input switches, output solenoids and relays must
be connected and functioning properly. The
Diagnostic ACE display is a tool to help the user
verify correct electrical functions of the machine.
CHECKING INTERLOCK
SWITCHES
The purpose of the interlock switches is to prevent
the engine from cranking or starting unless the
traction pedal is in NEUTRAL, the Enable/Disable
switch is in DISABLE and the Lower Mow/Raise
control is in the neutral position. Also, the engine
will stop when the traction pedal is depressed when
the operator is off the seat.
CAUTION
THE INTERLOCK SWITCHES ARE FOR THE
PROTECTION OF THE OPERATOR AND
BYSTANDERS, AND TO ENSURE CORRECT
OPERATION OF THE MACHINE, SO DO NOT
BYPASS OR DISCONNECT THEM. CHECK
OPERATION OF THE SWITCHES DAILY TO
ASSURE THE INTERLOCK SYSTEM IS
OPERATING. IF A SWITCH IS DEFECTIVE,
REPLACE IT BEFORE OPERATING THE 5200-
D. THE CONTROLLER HAS THE ABILITY TO
DETECT BYPASSED SWITCHES AND MAY
PREVENT THE OPERATION OF THE
MACHINE IF SWITCHES ARE BYPASSED.
DO NOT RELY ENTIRELY ON SAFETY
SWITCHES—USE COMMON SENSE!
To verify interlock switch function:
1. Park the machine on a level surface, lower the
cutting units, stop the engine and engage the
parking brake.
2. Open the control panel cover. Locate the wire
harness and connectors near the controller.
Carefully unplug the connector from harness.
