Operating Instructions
LEAK DETECTOR OPERATION
The TurfDefender is an electronic hydraulic fluid
leak detection device that fits inside the hydraulic
tank of your machine. It is a pressure-based system
that requires a sealed hydraulic tank to function
properly. Very small changes to the oil level in the
sealed tank result in a large movement of the leak
detector's internal float. The TurfDefender's internal
microprocessor analyzes the float movement and
determines if there is a leak in the system.
• Turn the ignition key to the "ON" position to
start the system. (The system will reset itself
whenever the ignition key is moved to the
"OFF" position. Wait 5 seconds, then move the
key to "ON" position to restart the system.)
• When the machine is started, the alarm will give
one short beep to indicate that everything is
operating properly. If the alarm makes no noise
at all, it should be checked by a mechanic.
• If the alarm gives four short beeps it means a
system problem has been detected and it should
be checked by a mechanic. The 4-beep pattern
will continue for approximately 1-
then stop, unless the ignition key is moved to
the "OFF" position.
Note: The low or high oil level 4-beep signal
may occur if machine is started on a
slope. Move the machine to a level sur-
face, move the ignition key to the "OFF"
position, wait 5 seconds, then move the
key to the "ON" position to restart the
system.
• If the alarm gives a loud continuous beep while
mowing and shuts off the cutting units, it means
that a leak has been detected. On the traction
unit, the red light on the steering console will
also blink, indicating the ECU has shut off the
cutting units.
CHECKING LEAK DETECTOR
OPERATION
The operation of the TurfDefender should be
checked if any of the following conditions occur:
24
1.
2.
3.
4.
5.
1
⁄ minutes,
2
If the TurfDefender is functioning normally:
1.
2.
If No beeps are heard:
a. No beeps are heard when the ignition
switch is turned "ON".
b. Any time the machine gives a series of four
short beeps.
c. False alarms occur.
Park the machine on a level surface, stop the
engine and engage the parking brake.
Open the control panel cover. Locate the leak
detector harness loopback connector with the
hydraulic symbol tag. Carefully unplug the
loopback connector from the harness connector.
Connect the Diagnostic ACE display connector
to the correct harness loopback connector.
Install the TurfDefender overlay decal (supplied
with the leak detector kit) onto the Diagnostic
ACE (Fig. 24).
Turn the key switch to the ON position, but do
not start the machine.
Note: The red text on the overlay decal refers to
inputs and the green text refers to outputs.
The red "Inputs displayed" LED (Light Emitting
Diode), on lower right column of the Diagnostic
ACE, should be illuminated. If the green
"Outputs displayed" LED is illuminated, press
and release the toggle button on the Diagnostic
ACE, to change LED to "Inputs displayed". Do
not hold the button down (Fig. 24).
When the "Inputs displayed" LED is lit, the
actual Float position (1 or 2 LED's on left row)
and "Oil level OK" LED should be displayed
(Fig. 25).
Press the toggle button until the green "Outputs
displayed" LED is lit. "Valve ON", "data line"
and "self diagnostic"LED's should be lit steadi-
ly. "Alarm ON" LED may be displayed tem-
porarily (about 5 seconds) (Fig. 26).
Note: If "data line" or "self diagnostic" LED's
are blinking, there is a problem in the
system.
