Cause
« Power is not supplied to the Lossnay, or power
outside specifications is connected.
« When using only 1 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 specifications (longer than 500 m).
« The remote controller is connected to TB5 (M-NET
transmission cable).
« PZ-52SF-E is connected to the Lossnay local
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 specifications (longer than 500 m).
« Multiple transmission cables are wired with multi
core cables.
« The type of external signal does not match the
connected terminal unit (charged, uncharged, Mr.
Slim signal).
« The type of external signal does not match the
pulse input switch (SW2-2) setting (level signal,
pulse signal).
« The external device signal is not being input.
« The external device and signal cable wiring is
longer than specifications.
12V DC, 24V DC:
Uncharged a-contact: Longer than 500 m
Mr. Slim signal:
« The Delayed Start mode is set at the remote con-
troller (PZ-41SLB-E).
« The ON Interlocked Operation mode or OFF Inter-
locked Operation mode is set at the remote con-
troller (PZ-41SLB-E).
« When using multiple Lossnay units, the external
control input signal is connected to a unit with the
"Sub" setting made.
Longer than limitations of
external device
Longer than 500 m
Corrective action
« Check the power supply to the
Lossnay.
« Set the Main/Sub (SW1) switch
to "Main." (refer to page 164)
« Check the length of the trans-
mission cable wiring.
« Connect the transmission cable
to TM2 5,6. (refer to page 163)
« Change to the PZ-41SLB-E
remote controller.
« Set the Main/Sub switch (SW1) of
the second and following Lossnay
units to "Sub." (refer to page 164)
« Check the length of the trans-
mission cable wiring.
« For the applied transmission
cable, wire the transmission
cables away from the other
transmission cable.
« Check the connection to the exter-
nal control input terminal (TM2) for
the type of external signal. (refer
to page 163, 164)
« Check the type of external signal
and the setting of the pulse input
switch (SW2-2). (refer to page 164)
« Check the external device.
« Check the length of the signal
cable wiring.
« Check the Delayed Start mode
setting at the remote controller
(PZ-41SLB-E). (refer to page 171)
« Check the Interlocked Operation
mode setting at the remote con-
troller (PZ-41SLB-E). (refer to
page 171)
« Connect the external control
input signal to the Lossnay unit
set to "Main."
