Corrective action
Check the items described in (1) [2].
If the error re-occurs, check for
noise on the transmission cable.
If the above does not correct the
problem, replace the Lossnay con-
trol circuit board or PZ-62DR-EA
remote controller.
Connect PZ-62DR-EA to the termi-
nals (TM4 [1] [2]). (See the Lossnay
Operating/Installation Instructions or
PZ-62DR-E Instruction Book.)
Check the items described in (1) [2].
If the error re-occurs, check for
noise on the transmission cable.
If the above does not correct the

trol circuit board or PZ-62DR-EA
remote controller.
Check the items described in (1) [2].
If the error re-occurs, check for

If the error re-occurs, check for
noise on the transmission cable.
If the above does not correct the
problem, replace the Lossnay con-
trol circuit board or PZ-62DR-EA
remote controller.
Set unique addresses to these
units.
Make the SW6 setting appropriate
for the model. (See Chapter 8. (8)
Setting status record (page 52).)
