(4) Troubleshooting 4: The Lossnay operation is disabled or irregular.
Lossnay checklist (Table 4)
1
The fan does not oper-
ate.
The fan does not operate
normally.
Connectors for the fan or connectors for the
Lossnay circuit board section are not cor-
rectly connected.
Power is not supplied to the Lossnay, or power
that does not follow speci
fi
cations is used.
When M-NET is used, Lossnay group set-
ting is not performed. (LED2 lights)
Check the lead wire connectors
and the Lossnay circuit board
section connectors.
Check the power supply.
Check the Lossnay address
and the group setting. (LED2
lights when not using M-NET.
This is not an error.)
3
The fan will not stop.
Trial operation switch (SW2-1) on the
Lossnay circuit board is set to ON.
The TM4 , output setting switch (SW2-
8) or the TM3 , output setting switch
(SW5-6) on the Lossnay circuit board is set
to ON.
Check the trial operation switch
(SW2-1). (Refer to page 23)
When SW2-8 or SW5-6 is ON,
the fan will stop 3 minutes after
OFF operation of the remote
controller. (Refer to page 14)
Interlocked operation
with external devices
(air conditioners) does
not occur.
The type of external signal does not match
the connected terminal block (charged,
uncharged, Mr. Slim 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
The Delay operation is set with the function
selection of PZ-60DR-E or PZ-41SLB-E, or
the function selection switch (SW5-1) on the
Lossnay circuit board.
The ON Interlocked or OFF Interlocked is
set with the function selection of PZ-60DR-
E or PZ-41SLB-E, or the function selection
switches (SW5-7, SW5-8) on the Lossnay
circuit board.
When multiple Lossnay units are used, the
external control input signal is connected to
a “Sub” Lossnay.
In a group of multiple Lossnay units with
M-NET, the external control input signal is
connected to a Lossnay unit other than the
one with the smallest address.
There is a communication error with the
remote controller or MELANS.
Check the external signal type
and the external control input
terminal (TM2) connection.
<When using PZ-60DR-E>
Check the external signal type
and the pulse input setting from
the function selection.
<When not using PZ-60DR-E>
Check the external signal type
and the pulse input setting
switch (SW2-2) on the Lossnay
circuit board. (Refer to page 18).
Check the external device.
Check the wiring length of the
signal cable.
Check the delay operation set-
ting of PZ-60DR-E or PZ41SLB-
E, and the function selection
switch (SW5-1) on the Lossnay
circuit board. (Refer to page 19)
Check the interlock mode set-
ting of PZ-60DR-E, PZ41SLB-
E, or the function selection
switches (SW5-7, SW5-8) on
the Lossnay circuit board. (Refer
to page 19)
Connect the external con-
trol input signal to the “Main”
Lossnay.
Connect the external control
input signal to the Lossnay unit
with the smallest address in the
group.
Check the remote controller or
MELANS.
