Cause
Multiple PZ-43SMF-E transmission
cables are wired using multicore
cables.
The power supply cable is too close
to the PZ-43SMF-E transmission
cable.
Faulty connection of the PZ-43SMF-E
transmission cable
The wiring length of the PZ-43SMF-E
transmission cable is longer than
specified (219 yd. (200 m) or more).
The Lossnay is used in the same
group as LGH-RX -E type Lossnay.
5
PZ-43SMF-E is connected to the
terminals (TB5 [A] [B]).
Faulty connection of the PZ-61DR-E
transmission cable
The Lossnay is used in the same
group as LGH-RX -E type Lossnay.
5
PZ-61DR-E is connected to the ter-
minals (TB5 [A] [B]).
Faulty connection of the PZ-61DR-E
transmission cable
The Lossnay is used in the same

Corrective action
Using the applicable cable, wire the
transmission cable away from one
another.
Wire the power supply cable at
least 2 inch (5 cm) away from the
transmission cable.
Check the transmission cable con-
nections.
Check the wiring length of the trans-
mission cable.
The LGH-F**RVX-E type Lossnay
cannot be used in the same group
as LGH-RX -E type Lossnay.
5
Connect PZ-43SMF-E to the termi-
nals (TM4 [1] [2]).
(See the Lossnay technical manual.)
Check the items described in (1) [2].
If the error re-occurs, check for
noise on the transmission cable.
If the above does not correct the
problem, replace the Lossnay circuit
board or PZ-61DR-E remote con-
troller.
The LGH-F**RVX-E type Lossnay
cannot be used in the same group
as LGH-RX -E type Lossnay.
