REASON
During production a number of changes have been made to this model as detailed
below.
below.
ACTION
The R210AM began production with the main wiring harness FW-VZA027URE0 plus
the surge components ( relay RRLY-A035WRE0 and resistor RR-WZA023WRE0 ).
Due to interpretation of IEC standard requirements and in-house testing, it was found
that the surge components were not required and therefore deleted. The main wiring
harness was changed to FW-VZA034URE0 to accommodate this change.

harness was changed to FW-VZA034URE0 to accommodate this change.
The circuit was then modified to improve design/reliability. This was completed in two
stages.
stages.
1.
A micro switch ( QSW-MA110WRE0 ) was added to the top latch position, plus
one additional link wire ( QW-QZA006URE0 ) was fitted from the new latch
switch to the vari switch terminal as described below.
Take the orange wire from the vari switch and fit it to the common terminal on
the new latch switch (this may require pulling the orange wire until it fits). Now
fit the new lead wire from the normally open contact of the new latch switch to
the vari switch terminal. The terminal must now be insulated.

Later production units incorporated the link wire into a new harness, this
harness has been given the part number FW-VZA034URE1.

Résumé
•
May 1997 production ( serial numbers starting 705 ) surge components deleted.
•
September 1997 production ( serial numbers starting 709 ) switch and link fitted.
•
October 1997 production ( serial numbers starting 710 ) new wiring harness fitted.
•
Note that the change from the link wire to new harness occurred during October 1997.
