Troubleshooting
If you experience a controller problem, check the programming for a possible programming error and the
list of problems and solutions listed below. If the problem continues, contact your local Toro distributor
for assistance.
Lithium Battery installation (optional)
An optional 3.9V lithium battery (P/N 363-2200) can be installed to sustain the controllers clock time and the
currently active program information for approximately 90 days with no additional power applied.
Procedure
1. Turn off power to controller at power supply switch.
2. Remove phillips screws from corners of control panel and
carefully lift panel up.
3. Turn control panel over, resting it face down on pedestal.
Connector cables can remain attached to PCB for this
procedure.
4. Remove five phillips screws from back of control panel
PCB and separate PCB from faceplate assembly.
5. Locate battery pin sockets located on front side of PCB
as shown at right. Insert battery carefully to avoid bending
contact pins. The pins are unevenly spaced allowing the
battery to be installed easily in one direction only.
Do not
force battery pins into sockets. See Warning above.
6. Reassemble control panel assembly and reinstall into
pedestal.
7. Restore power to controller at power supply switch.
