TBOS
™
Field Transmitter
If you are using 3M DBM wire con-
nectors, make sure the wires have
not been stripped. Unlike other wire
connectors on the market, DBMs
are designed to cut through the
insulation to make a water-resistant
coupling without removing the
insulation. Push the wires all the
way into the wire connector. Be sure
to crimp the black cap all the way
down (gel should ooze out of the
top) to ensure a water resistant con-
nection. Gently pull on the wires to
make sure they are secure. If the
insulation has been stripped, re-cut
the wires and repeat the steps
above.
Possible cause: The TBOS Rain Shut-off Device is
wet.
Solution:
Flip the TBOS Rain Shut-off Device
switch to off. If you have an old style
UNIK Control Module, cut the TBOS
Rain Shut-off Device wires. Connect
the black wires from the Control
Module to the black field wires.
Carry out a manual stop and then
repeat the manual start.
Problem:
Faulty transmission
Possible cause: The optical connector on the
Control Module and/or the Field
Transmitter is dirty.
Solution:
Clean the connector(s).
Possible cause: The battery is weak.
Solution:
Replace the battery.

Problem:
Locked display or keypad
Possible cause: The microprocessor did not reset
properly.
Solution:
Remove the battery. Short the TBOS
Field Transmitter battery clip (not
the battery) contacts together with a
paper clip or other piece of metal
for 30 seconds. Reinstall a fresh bat-
tery.
Problem:
Station does not start
Possible cause: No run time has been programmed
for that station.
Solution:
Transmit a run time to the Control
Module.
Possible cause: The On-off Mode is activated (X on
Sprinkler icon ).
Solution:
Permit irrigation by deactivating the
On-off Mode.
Possible cause: Another station is in operation.
Solution:
Use the manual station option to
turn off that station.
Possible cause: The battery is weak.
Solution:
Replace the battery.
Possible cause: A wire connection is faulty.
Solution:
If you are using King wire connec-
tors, gently pull on the wires to
make sure they are secure. If the
wires are loose, cut the wires. Strip
0.5 in. (1.25 cm.) of the insulation
off the wires. Twist the wires, then
push the wires into a new King con-
nector and twist the connector
around the wires. Gently pull on the
wires to make sure they are secure.
