9. HAND CRANK OPERATION
WARNING
Do NOT connect power to unit until instructed to do so. The hand crank is
for emergency use only and should NOT be used when there is power
connected to the door. Serious injury or death could result if the door
motor activates while the crank is installed.
NOTE: A factory installed Brake Release Cable Assembly is attached to the
motor brake assembly. No installation or adjustment is necessary.
WARNING
Do NOT pull Cable unless crank handle is engaged with motor eyelet and
secured as instructed on the Hand Crank Safety Instruction sticker attached to
the door jamb or curtain guide. Safe use requires two (2) people.
Do NOT use Motor Brake Release Pull Cord to allow curtain to free fall.
Uncontrolled curtain drop using the Motor Brake Release Pull Cord will
activate DROP STOP DEVICE.
NOTE: The brake release must remain in the release position at ALL TIMES
DURING MANUAL OPERATION. If the brake is allowed to re-engage it will
become impossible to turn the crank handle.
NOTE: A power interlock switch is located on the hand crank interlock
support bracket to prevent accidental motor operation, should the power
be restored while the Hand Crank is engaged. Do NOT disconnect power
interlock switch.
TO OPERATE: This task requires two (2) people to perform. Installation of the
Hand Crank and Interlock Switch occurs in Step 13A on page 16.
A. Disconnect ALL electrical power supply.
B. Remove hand crank from the Crank Handle Support Bracket.
– This releases the power interlock switch (a backup protection to
ensure there is no power to the gearmotor).
C. Insert the hook on the crank handle through the eyelet mounted on the
bottom (fan end) of the motor, Fig. 4–I.
D. Once the hook is securely engaged.
– Firmly secure the crank handle with BOTH hands.
– Have an assistant pull down and HOLD the brake release cable. You
will feel an immediate increase in the tension on the handle.
