Step 9:
to increase door closing power. Door control is shipped
set at midpoint of power setting. Maximum closing
power can be achieved with 8 (360°) clockwise turns of
the power adjustment screw.
Adjust closing power of unit (See Fig. 3) - Using a 1/8”
allen wrench, turn the power adjustment shaft clockwise
Adjust Hydraulic valves using a 1/8” hex wrench to
obtain proper door closing speeds. See following

Turn power to unit on at the Unit Power Switch and turn the
Breaker Switch to “RESET”.
Using a short jumper cable, jump terminals 1 and 2, see Fig.
6 below, to activate unit. When door reaches 20 , switch
Breaker Switch to “
” position cutting power to the unit.
Allow door to fully close (door may be manually pulled
closed).
Once door has fully closed, manually open door slightly and
insert a 1/8” allen wrench (provided with screw pack) into the
clutch assembly as shown below to create a small gap
between the two clutch components.
Manually close door and remove allen wrench from clutch
assembly.
Adjust Closing Ring Position (See Fig. 8) - Loosen 8-32 set
screw located on Close Position Ring with 5/64” hex wrench
provided. Rotate Assembly until Closed Position Magnet
aligns with Reed Switch.
Adjust Open Ring Position - Loosen 8-32 set screw located
on Open Position Ring with 5/64” hex wrench provided.
Rotate Ring Assembly until Open Position Magnet is
approximately 180° from Closed Position Magnet.
Flip Breaker Switch to “RESET” to turn power on. Jump
terminals 1 and 2 (as shown in Step 13) to activate door.
Note open position of the door. Allow door to close.
Loosen and readjust Open Position Ring as necessary to
obtain desired door open position. Tighten set screw.
Make all connections necessary for any accessories to the
4-position terminal on “T1” bracket (see Pages 6 - 8).
Make necessary adjustments to inverter (see Page 6).
Replace cover and cover screws.
