2. MECHANICAL ADJUSTMENTS
Elevator Height (Address) Adjustment
Note: This adjustments is necessary when the system controller
(IC301), variable resistor (RV301), slider (R), slider (L), or
chassis (ELV) was replaced for any repair.
Connection:
power supply
master unit
+
GND
BUS cable
CDX-705/EXCD-3
Adjustment Method:
1. Connect this set to the master unit (e.g. MDX-C670/C670RDS),
load a disc magazine, and place the set vertically as shown below.
2. Connect the regulated power supply to the master unit, and turn
the power on.
3. Press the DISC button on the master unit and select DISC 5.
4. At this time, if the elevator shaft does not position between comb
teeth A and B at addresses 5 and 6 as shown below, adjust the
following.
5. Press repeatedly the DISC + and – buttons on the master unit so
that the elevator shafts moves from address 6 to address 5, or from
5 to 6. At this time, adjust RV301 on the main board so that the
elevator shaft positions smoothly between comb teethA and B.
6. Further, place the set horizontally and make same adjustment as
mentioned above.
7. After adjustment at addresses 5 to 6 is finished, check all opera-
tions from addresses 1 to 10 with the set placed vertically and
horizontally respectively to confirm that the elevator shaft posi-
tions in a range between comb teeth A to B.
