Cause
« Power is not supplied to the Lossnay, or power
that does not follow specifications 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 cable
is longer than specified (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 (termi-
nal block for M-NET transmission cable).
« PZ-52SF-E (Lossnay remote controller for M-NET)
is connected to the Lossnay remote controller.
« When using multiple Lossnay units, the Main/Sub
switch (SW1) on the Lossnay circuit board of the
second or following unit is set to "Main."
« The overall wiring length of the transmission cable
is longer than specified (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?
« Is the specified 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, seri-
al 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 specified.
12 V DC, 24 V DC:
Uncharged a-contact: Longer than 500 m
Mr. Slim signal:
« "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.)
Longer than limitations of
external device
Longer than 500 m
Action
« 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 1, 2.
« Change to the PZ-60DR-E or
PZ-41SLB-E remote controller.
« 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 remote
controller.
« 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 con-
trol input terminal (TM2).
« <When using PZ-60DR-E>
Check the type of external signal
and verify the pulse input setting
from the function selection.
(Refer to page C-66)
<When not using PZ-60DR-E>
Check the type of external signal
and the setting of the pulse input
switch (SW2-2) on the Lossnay
circuit board. (Refer to page C-73).
« 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).
