FUNCTIONAL UPGRADE
To lock the Gear Ratio (Transmission), take the unit as factory set and do
as follows:
• Using a conventional fl at headed screwdriver (approx. 4mm wide) turn the
yellow wheel of the Gear Interlock to the left or right according to your
chosen setting (either 33
o
or 90
o
) until it noticeably locks in place. Refer to
Figures 15 & 16.
• In order to set the Gear Ratio (Key 4, Figure 8A) any locks in place must
fi rst be released. Hence the yellow wheel of the gear interlock must fi rst be
put into the neutral position in order to reset the Gear Ratio if necessary,
e.g. after replacing the actuator. (Refer to the SIPART PS2 Operation
