System checklist ( Table 1-2 )
When using PZ-60DR-E or interlocking with external devices ( Table 1-2-1 )
No. Error
1 • Remote controller
display does not
appear.
• The power display
" " does not
appear on the
remote controller.
• The remote con-
troller continues to
display " H0 " .
2 Remote controller
does not operate.
( Communication er-
ror display )
3 Interlock operation
with external device
does not occur.
Cause
 Power is not supplied to the Lossnay, or power
that does not follow specifications is used.
 When only one Lossnay is used, 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 547 yd. (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 ) .
 When multiple Lossnay units are used, 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 547 yd. (500 m) ) .
 Multiple transmission cables are wired with
multi core cables.
 When two remote controllers are used, are PZ-
60DR-E and other remote controller 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,
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 specified.
12 V DC, 24 V DC: Longer than limitations of
external device
Uncharged a-contact: Longer than 547 yd. (500 m)
Mr. Slim signal: Longer than 547 yd. (500 m)
 " DELAY OPERATION 'ON' " ( PZ-60DR-E ) is set.
( When PZ-60DR-E is used, during the delay
operation, LED1 ( green ) on the Lossnay circuit
board will be lit. )

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 transmis-
sion cable wiring.
 Check the number of units con-
nected.
 Connect the transmission cable
to TM4 1, 2.
 Set the Main/Sub switch ( SW1 )
of the second and following
Lossnay units to " Sub " .
 Check the length of the transmis-
sion cable wiring.
 Use suitable cables to 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
control input terminal ( TM2 ) .
 <When using PZ-60DR-E>
Check the type of external signal
and verify the pulse input set-
ting from the function selection.
( Refer to page 34 )
<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 30 ) .
 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 ) .
