ADJUSTING THE MECHANICAL CLUTCH
The 844R Rev operator is equipped with a mechanical clutch.
Procedure for adjusting the action threshold of the mechanical
clutch (we advise you to set it in compliance with current
standards):
1)
Cut 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
Fig. 26.
To increase torque, turn the screw clockwise.
Â
The operator is supplied with clutch set to maximum value.
Therefore, you should initially turn the screw counter-
clockwise to reach optimum setting.
To reduce torque, turn the screw counter-clockwise.
3)
Power up the automated system and check if the torque
you have just carried out is correctly set.
6.7.
CHECK OF STOP POINTS
Take care over the setting of the post-travel-limit deceleration
and braking: if deceleration is too long or braking is insufficient,
the marker fitted on the gate’s rack (magnet) can overtake
the sensor until the latter is disengaged. When the gate stops,
make sure that only the limit sensor in question is engaged. If the
sensor is engaged and then disengaged, or both the limit sensors
are engaged, check the decelerations again as indicated in
the instruction of the unit.
6.8.
CHECK OF SAFETY DEVICES AND ACCESSORIES
Check correct operation of the following: all safety and anti-
crushing devices and the accessories used in the system.

FINAL OPERATIONS
After completing installation, remove the breather screw (see
fig. 27) and apply the danger signal tape on the top of the
cover (Fig. 28).
Fit the side panels by pressure, and secure the cover with the
supplied screws.
Hand the “User’s Guide” to the Client, explain correct operation
and use of the gear motor, and indicate the potentially
dangerous areas of the automated system.
