DIAGNOSTIC LIGHT (Fig. 19)
The RM 6700-D is equipped with two diagnostic lights which
indicate whether or not the electronic controllers are function-
ing correctly. The diagnostic light for the main (#1 controller
is located on the steering tower panel. When the #1 electronic
controller is functioning correctly and the key switch is moved
to the ON position, the (#1) controller diagnostic light will be
illuminated for approximately 6 seconds. The light will not
illuminate if the controller detects a malfunction in the electri-
cal system.
The diagnostic light for the secondary (#2) electronic con-
troller is located in the right-hand console by the height-of-cut
selector knob. This green light should illuminate if the con-
troller is functioning correctly.
If the diagnostic lights are not illuminated when the key switch
is in the ON position, this indicates that the electronic con-
trollers are not operating. Possible causes are:
1.
Loopback connectors (under control panel cover) are not
connected.
2.
The electronic controller light is burned out.
3.
Fuses are blown.
4.
The light is not functioning correctly.
Check electrical connections, input fuses and the diagnostic
light bulb to determine malfunction. Make sure the loopback
connectors are secured to the wire harness connector.
DIAGNOSTIC ACE DISPLAY
The RM 6700-D is equipped with two electronic controllers
which control most machine functions. The controllers deter-
mine what function is required for various input switches (i.e.
seat switch, key switch, etc.) and turns on the outputs to actu-
ate solenoids or relays for the requested machine function.
For the electronic controllers to control the machine as desired,
each of the input switches, output solenoids and relays must be
connected and functioning properly. Electronic controller #1
controls the main five cutting units. Electronic controller #2
controls the two outer cutting units.
