*1 LC: Lossnay set to Main SLC: Lossnay set to Sub RC, SRC: remote controller (PZ-41SLB-E)
*2 Because the LGH-200RX type is loaded with 2 control circuit units, "SLC" may display even with only 1 Lossnay.
When "SLC" displays, check and perform maintenance on the upper side circuit.

Cause
Corrective action
« Turn off the main power supply and set the
Main/Sub switch (SW1) (first unit to main, second
and following units to sub). (refer to page 164)
« Wire the transmission cable away
from the other transmission cable.
« Wire the transmission cable at least 5
cm away from the power supply cable.
« Check the transmission cable con-
nection. (refer to page 163)
« Check the length of the transmis-
sion cable wiring.
« Wire the transmission cable away
from the other transmission cable.
« Wire the transmission cable at least 5
cm away from the power supply cable.
« Check the transmission cable con-
nection. (refer to page 174)
« Check the length of the transmis-
sion cable wiring.
« Check the test operation switch.
(refer to page 169)
« Replace the table.
« Remove the load and check or
move the damper board by hand.
« Check the connection of the lead wire's
connectors and the circuit connector.
« Check the connection of the lead
wires connectors and the circuit
connector.
« Check the connection of the lead
wires connectors and the circuit

« Wire the transmission cable away
from the other transmission cable.
« Wire the transmission cable at least 5
cm away from the power supply cable.
« Check the transmission cable con-
nection. (refer to page 163, 164)
« Check the length of the transmis-
sion cable wiring.
