Check the above checkpoints.
Power supply (Table 1-1-1)
Do the transmission cables meet regulations? (Type, diameter)
Checkpoint
1
No.
2
Is the transmission cable wired at least 5 cm away from the power supply
cable?
3
Are multiple transmission or signal cables wired to the same power cable
duct?
4
Are multiple transmission cables wired with multi core cables?
5
Are the transmission cables securely connected to the terminals?
6

7
Is the wiring length of the transmission cable within the regulations?
Basic system (PZ-60DR-E, PZ-41SLB-E): Total extension within 500 m
M-NET control: Maximum extension within 200 m, total extension within 500 m
Action
Use specified cables.
Wire the transmission cable at least
5 cm away from the power supply
cable.
Wire the transmission cables away
from the signal cables.
Using suitable cables, wire the
transmission cables so that they are
separated from one another.
Connect them securely.
Connect them to the specified termi-
nal blocks.
Wire within the regulations.
(Refer to page C-36)
Transmission cables (Table 1-1-2)
Check the following checkpoints when connecting with the remote controller, M-NET controller, or City Multi indoor units.
8
Is the Main/Sub selection switch (SW1) on the Lossnay circuit board set
correctly?
When using one Lossnay unit: Set the unit to “Main”.
When using multiple Lossnay units: Set the first unit to “Main” and the
second and following units to “Sub”.
Set the switches correctly.
9
When using M-NET
Is the address setting on the Lossnay circuit board (SA1, SA2) set to the
correct number?
Make the setting so that the
address does not duplicate that of
other devices within M-NET control.
10
When PZ-60DR-E is not used, are the function selection switches (SW2,
SW5) on the Lossnay circuit board set correctly?
Set the switches correctly to corre-
spond with the application.
(Refer to page C-72)
11
When PZ-60DR-E is used, is the function selection set correctly?
Set it correctly to correspond with
the application.
