Functions, Programming and Adjusting
Programming and
Adjusting
The SQUARE 940-2 control system permits to adjust the DICTATOR DICTAMAT door
operator exactly to each door. This is a vital condition for the safety at powered doors.
The increased demands concerning the safety of the "machine door" due to the EN12453
standard require a control and putting into operation by a trained and authorised techni-
cian. Therefore all safety relevant parameters are only accessible through a password. The
below mentioned functions and parameters only give a general idea as the SQUARE940-2
offers a much larger range of adjustments/functions.
All adjustments are done with the three adjustment keys on the control module.
•Dead Man or Impulse Function
for the keys
OPEN
and
CLOSE
(can be choosen separately
for both directions, e.g. impulse OPEN, dead man CLOSE)
•Automatic Closing: As soon as the position OPEN has been reached the door closes
automatically after a preset time (adjustable between 1 - 999 seconds)
•Alternating Impulse OPEN/CLOSE
, also in combination with automatic closing
•Partial Opening: The door opens only partially after pressing a separate push button
(additional Open position for persons) (separately adjustable hold-open-time for this
position)
•STOP (Normal Stop when opening, Fast Stop when closing).
•EMERGENCY STOP: This works the same way as the safety equipment on the closing
edge. Stopping distance according to EN 12453.
•Safety Equipment (SHE): Different safety equipment can be connected to meet the
EN12453. The function of the safety equipment is cancelled in the final positions.
After the safety equipment has been activated a new operating command is necessary
to get the door moving again.
Securing the closing edge (direction CLOSE): When this SHE is activated, the door
stops within the required distance and then reverses until it is again completely open.
This SHE is in function only during closing.
Securing the opening edge (separate connection): When activated, the door reverses
until it is again completely closed. SHE in function only during opening.
Additional safety type D, e.g. by a light barrier in closing direction (see table on page
04.007.00): Door stops with a Fast Stop (see below).
If the safety equipment should fail, an emergency service for the door can be adjusted
(dead man operation). The door moves at creep speed only. As long as the emergency
service has not been adjusted, the door can no longer be operated by motor.
In order to achieve an optimum adjustment of the door drive to the door different
motor parameters can be adjusted. Amongst them are e.g.:
- Motor Rating (adaption to the connected motor)
- OPENING Speed / CLOSING Speed (separately adjustable)
- Creep Speed before reaching the positions OPEN and CLOSED (speed is reduced
before reaching the final position, so that no separate final dampers are required,
separately adjustable)
- Acceleration and Deceleration Ramps: Depending on the door weight and its easy
movement
- Fast Stop: Adjustment of the Stop in closing and opening direction (separately adjustable)
- EMERGENCY STOP: Adjustment of the STOP characteristics upon activation of the safety
equipment or by the Emergency Stop push button
