Check the power supply to the
Lossnay. (Refer to Table 1-1-1)
Set the Main/Sub (SW1) switch
to “Main”.
Check the length of the trans-
mission cable wiring.
Check the number of units con-
nected.
Connect the transmission cable
to TM4 , .
Change to the PZ-60DR-E or
PZ-41SLB-E remote controller.

No.
• Remote controller
display does not
appear.
• The power display
“ ” does not
appear on the
remote controller.
• The remote con-
troller continues to
display “HO”.
Power is not supplied to the Lossnay, or power
that does not follow speci fi cations is used.
When using only one Lossnay, the Main/Sub switch
(SW1) on the Lossnay circuit board is set to “Sub”.
The overall wiring length of the transmission ca-
ble is longer than speci fi ed (longer than 500 m).
Is there a connection of 3 or more remote con-
trollers, or 16 or more Lossnay units?
The remote controller is connected to TB5 (ter-
minal block for M-NET transmission cable).
PZ-52SF-E (Lossnay remote controller for M-NET)
is connected to the Lossnay remote controller.
2 Remote controller
does not operate.
( Communication er-
ror display)
When using multiple Lossnay units, the Main/
Sub switch (SW1) on the Lossnay circuit board
of the second or following units is set to “Main.”
The overall wiring length of the transmission ca-
ble is longer than speci fi ed (longer than 500 m).
Multiple transmission cables are wired with
multi core cables.
When two remote controllers are used, are PZ-
60DR-E and PZ-41SLB-E being used together?
Set the Main/Sub switch (SW1)
of the second and following
Lossnay units to “Sub”.
Check the length of the trans-
mission cable wiring.
Using suitable cables, wire the
transmission cables so that they
are separated from one another.
Use the same type of the re-
mote controller.
Interlock operation
with external devices
does not occur.
Is the speci fi ed power being supplied to the
Lossnay unit?
Are the signal cables from the external devices
wired according to regulations?
The type of external signal does not match the
connected terminal unit (charged, uncharged,
serial signal).
The type of external signal does not match the
pulse input setting (level signal, pulse signal).
The external device signal is not being input.
The external device and signal cable wiring is
longer than speci fi ed.
12 V DC, 24 V DC: Longer than limitations
of the external device
Uncharged a-contact: Longer than 500 m
Mr. Slim signal: Longer than 500 m
“DELAY OPERATION ‘ON’” (PZ-60DR-E) or
“Delay time” (PZ-41SLB-E) is set. (When using
PZ-60DR-E, during the delay operation, LED1
(green) on the Lossnay circuit board will be lit.)
Refer to Table 1-1-1.
Refer to Table 1-1-3.
Check the type of external signal
and the connections between
the external signal and external
control input terminal (TM2).
<When using PZ-60DR-E>
Check the type of external
signal and verify the pulse input
setting from the function selec-
tion. (Refer to page 29)
<When not using PZ-60DR-E>
Check the type of external sig-
nal and the setting of the pulse
input switch (SW2-2) on the
Lossnay circuit board. (Refer to
page 25).
Check the external device.
Check the length of the signal
cable wiring.
Check the Delay operation set-
ting with the remote controller
(PZ-60DR-E or PZ-41SLB-E).
