Current Sensitivity Adjustment; Speed Adjustment - Nice Mindy A924 Manuel D'instruction Pour L'installateur

3.8.1) Current sensitivity adjustment

To limit the forces brought into play by the movement, a requirement
required by the regulations, the control unit features two trimmers TR2
(ref. C, Fig. 1) and TR1 (ref. D, Fig. 1) which allow the cut-in threshold
of the current sensitivity device to be varied during the opening
manoeuvre and closing manoeuvre respectively. If an obstacle is detect-
ed while the door is moving, it stops and, if the "Semiautomatic" or
"Automatic" operating mode is active, a manoeuvre in the opposite
direction is performed.
If the current sensitivity device cuts in during the closing manoeuvre, the
control unit reverses the direction of movement and the opening
manoeuvre, unless interrupted, terminates with the door against the
mechanical opening stop – position 1 (position reconfirmation)

3.8.2) Speed adjustment

In order to reduce the kinetic energy released following an impact with an obstacle, as well as adjusting the cut-in threshold of the current
sensitivity device the speed of the door during normal operation can also be reduced.
Speed can be adjusted:
• in the "Man present" mode only with the motor stopped,
• in the "Semiautomatic" or "Automatic" mode either with motor stopped or while the door is moving (except for the acceleration and deceleration
phases).
Table "H" Adjusting speed:
1. Press and hold down the "Memory" button (Ref. J, Fig. 1)
2. After a second...
press and hold down the "Close" button (ref. K, Fig. 1) to decrease speed, or
♦
press and hold down the "Open" button (ref. I, Fig 1) to increase speed
♦
3. As soon as the speed has reached the required value, release the buttons (the new speed is automatically memorised)
N.B. The adjustment system is effective until the min. or max. limit values corresponding to the speeds indicated in the motor instructions book
are reached; when these limits are reached the "OK" led lights up and remains on when the maximum value has been reached and off when the
minimum value has been reached.
In order to further increase the safety level, if the current sensitivity
device cuts in three times consecutively and prevents the door from
closing properly, movement is stopped preceded by a brief inversion.
TR2 = Opening manoeuvre current sensitivity adjustment.
TR1 = Closing manoeuvre current sensitivity adjustment.
