«
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?
«
Set the Main/Sub switch (SW1)
of the second and following

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.
3 Interlock operation
with external device
does not occur.
«
Is the specified power being supplied to the
Lossnay unit?
«
Are the signal cables from the external devices
wired according to regulations?
«

«
“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 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).
