Action
Check the addresses of devices in
the system.
Check the power supply to Lossnay.
Check the Lossnay address.
Using suitable cables, wire the
transmission cables so that they
are separated from one another.
Check the transmission cable connection.
Check the length of the transmis-
sion cable wiring. ( See the techni-
cal manual for details about the
regulations. )
Check the trial operation switch.
( Refer to page 25 )
When external devices are con-
nected, check the external devices.
When external devices are not
connected, check the TM3
output setting switch ( SW5-6 ) .
( Refer to page 25 )
Remove the rod, and check whether
the dampers can be moved manually.
Check the connection of the lead wire
connectors and the circuit connectors.
Check that the switch (SW5-10) is
OFF. ( Refer to page 26 )
Check and replace the circuit
board.
Check and replace the fan motor.
Check the connection of the lead
wire connectors and the circuit
connectors.
Check the connection of the lead
wire connectors and the circuit
connectors.
Check the controller where the er-
ror occurred.
Replace the circuit board.
Adjust the wiring of the power sup-
ply unit.
