Turfdefender Tm Leak Detector (Optional) - Toro Reelmaster 5210 Service Manual

TurfDefender Leak Detector (Optional)
TM
The optional TurfDefender
fluid leak detection device that fits inside the hydraulic
reservoir of your machine (Fig. 12). It is a pressure
based system which requires a sealed hydraulic reser-
voir to function properly. Very small changes to the oil
level in the sealed reservoir result in movement of the
leak detector's internal float. The internal microproces-
sor of the TurfDefender analyzes the float movement
TM
and determines if there is a leak in the hydraulic system.
D Turn ignition switch to "ON" position to start the sys-
tem. The system will reset itself whenever the igni-
tion switch is moved to "OFF". Wait 5 seconds, then
move switch to "ON" position to restart the system.
D When the machine is started, the alarm should give
one short beep to indicate that everything is operat-
ing properly. If the alarm makes no noise at all, see
Checking TurfDefender
D If the alarm gives 4 short beeps, a system problem
has been detected and it should be checked by a
technician.
NOTE: The 4 short beep signal may occur if the ma-
chine is started on a slope. Move machine to a level
surface, move ignition switch to "OFF" position, wait
5 seconds, then move switch to "ON" position to re-
start the system. Repeat this cycle twice.
D If the alarm gives a loud continuous beep while mow-
ing and the cutting units are shut off, a hydraulic leak
has been detected. On the traction unit, the diagnos-
tic light on the control panel will also blink indicating
the ECM has shut off the cutting units.
Checking TurfDefender
TM
When any of the following conditions occur, the opera-
tion of the TurfDefender
TM
A. No beeps are heard when ignition switch is
turned "ON".
B. Any time the machine gives a series of 4 short
beeps.
C. False alarms are observed.
1. Park machine on a level surface, lower cutting units,
stop engine and engage parking brake.
2. Raise hydraulic reservoir cover. Locate leak detector
wire harness loopback connector identified with a green
hydraulic symbol tag (Fig. 12). Carefully unplug loop-
back connector from harness connector.
3. Connect the Diagnostic Display connector to the cor-
rect harness loopback connector. Install TurfDefender-
overlay decal (supplied with TurfDefender

Diode), on lower right column of the Diagnostic Display,
should be illuminated (Fig. 14). If green "Outputs Dis-
played" LED is illuminated, press and release the toggle
