Symptom
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 (200 m or more).
PZ-43SMF-E is connected to the ter-
minals (TB5 [A] [B]).
Faulty connection of the PZ-62DR-E
transmission cable
PZ-62DR-E is connected to the ter-
minals (TB5 [A] [B]).
Faulty connection of the PZ-62DR-E
transmission cable
Faulty connection of the PZ-62DR-E
transmission cable
Faulty connection of the PZ-62DR-E
transmission cable
The group contains two or more Loss-
nay units with the same address.
The model selection switch (SW6) is
not set correctly.
Cause
─ 33 ─
Corrective action
Using the applicable cable, wire
the transmission cable away from
one another.
Wire the power supply cable at
least 5 cm away from the transmis-
sion cable.
Check the transmission cable
connections.
Check the wiring length of the
transmission cable.
Connect PZ-43SMF-E to the termi-
nals (TM4 [1] [2]). (See the Lossnay
Operating/Installation Instructions or
PZ-62DR-E Instruction Book.)
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
control circuit board or PZ-62DR-E
remote controller.
