3. 2 CARD CONTROLS
Card OPER02 contains also two push-buttons for the operation in Test mode.
When power supply is connected to the card, if both the push-buttons are kept under pressure
for at least 1 second, the card moves into test mode, thus ignoring the control panel controls.
If the push-buttons are pressed again for 1 second, the card shall resume the standard operating
mode.
Anytime voltage issupplied to the card, itwill set into the standard operation mode, i.e.controlled
from the control panel.
4. OPERATION
The device does not carry out any control autonomously; it will carry out only the controls which
come from the control panel.
The sole exception is the stopping of the doors in case of intervention of either the moving edge
or the photocell.
4.1 DOOR OPENING
Door opening is carried out with the max torque available with no constraint.
The max. speed which can be reached depends upon:
· Trimmer adjustment <I>
· Resisting torque of doors and kinematics
The values ofAcceleration, Deceleration, Opening Slow Speed, Maintaining Current at the End
of Opening are fixed and unchangeable.
The doors open at the established speed until the monostable RAis reached.
Such monostable is to be located in such a way that the slow speed movement is reduced to
the minimum at the end of the deceleration.
If monostable RAis read before the end of the acceleration, as in the case of re-opening of the
doors, the beginning of the deceleration is delayed in compliance with the actual speed of the
doors.
If – in case of door closing - reopening is requested before the RAmonostable is exceeded - la
the reopening shall be carried out at slow speed.
The opening sensor contact (FA1-FA2) opens when the doors are completely open, when the
opening maintaining current is applied.
4.2 DOOR CLOSING
Door closing is carried out with torque control until monostable EC closes.
The doors operate at the established speed until they reach monostable RC. This monostable
is to be adjusted so that – at the end of the deceleration – the movement of the floor doors at
slow speed is reduced to the minimum.
If monostable RC is read before the end of the acceleration, the beginning of the deceleration
is delayed based upon the actual speed of the doors.
