FINAL OPERATIONS

6.7. 

CHECK OF STOP POINTS

Be careful when setting the post-limit-switch deceleration 

and braking. If the deceleration is too long and braking is 

insufficient, the magnet or steel plate fitted on the gate's rack 

can overshoot the sensor until it is disengaged. When the gate 

stops, check that only the light limit-switch is engaged. The 

relevant LED must be OFF. If it went OFF and then ON again, 

or if both limit-switch LEDS are OFF, you must reduce the 

post-limit-switch deceleration value and/or increase the braking 

value (see Section 5.5.2).

6.8. 

SAFETY DEVICES AND ACCESSORIES 

CHECK

Check for the correct operation of all safety equipment, anti-

crushing devices (ENCODER sensor), and accessories used in 

the system. 

• 

Snap-fit the side panels, put the equipment's cover on 

and secure it with the supplied screws (Fig. 46).

• 

Remove the vent stop screw (Fig. 47).

• 

Explain to the customer the correct operation and use of 

the operator, and indicate the potentially dangerous areas 

of the automated system.

Notes on Plate Positioning

• 

To ensure correct operation, allow at least 3/4 inch from the me-

chanical stop limit in the gate stop position. Carry out this check 

after determining the values of the pre- and post-limit switch 

decelerations (see Section 5.5.2.) and after running at least one 

complete cycle of the automated system.

• 

The distance between the limit-switch and the plates must be < 

3/16 inch.

the status of the inputs.
Note the following:

   = open contact

Check the status of the LEDs as per the following table.

6.6. 

MECHANICAL CLUTCH ADJUSTMENT

In addition to its electronic safety devices (encoder and force 

adjustment), the 844 operator is also equipped with a mechanical 

clutch.
For gate force and the encoder, please consult Sections 5.5.1 and 

5.5.2.

Adjusting the Operating Threshold of the Mechanical Clutch:

1.  Cut electrical power to the automated system.

2.  Keep the motor shaft locked with a wrench and turn the clutch 

adjustment screw with an Allen wrench or screwdriver as shown in 

Fig. 44 Ref. A.

  - To increase torque, turn the screw clockwise.
  - To reduce torque, turn the screw counter-clockwise.

  The operator is supplied with the clutch set to maximum level. 

Therefore, you must initially turn the screw counter-clockwise 

to reach the best setting.

3.  Power up the automated system and check that the torque you 

have just set is correct.

  The operator is supplied as standard with a clutch adjustment 

spring for gates up to 2200 lbs. For heavier gates, use the sup

-

plied alternative spring. For spring replacement instructions, 

see Fig. 44 Ref. B.
