Technical manual: SQUARE 940-2
7. Setup: Placing into operation with limit switches
7.1 GENERAL INFORMATION
Please note that the Quick Setup is aborted if the position counter is exceeded during setup.
Use the «Pulse Count» setting to reduce the number (see System Setup -> Pulse Count -> e.g. 2).
To check whether the positions within the number range of the controller (-32000 - +32000),
use System diagnostic -> Position and move the door to fully open and fully closed position in
«Dead-man» with the membrane keys.
Then check if the value is within the range.
Note: At the start of the teach-in travel, the door/gate should be in the half-open position. If the
operator moves against a mechanical stop in the open or closed position during the check of
the direction of movement, error messages with abort of the learning travel are possible.
IMPORTANT
After the end positions have been learned during initial startup, the
motor load and the power reserve of the operator must be checked.
To do this, change the value in Express menu item 5.6 to „Motor Cur-
rent“. The motor current is now displayed in amperes on the home
screen.
The maximum ampere value for continuous operation can be read on
the motor nameplate at 230V.
Depending on local requirements and the ED of the system, the motor
current shown in the controller display should not exceed the rated
value of the motor.
Short-term exceeding of the nominal value during acceleration travel of
the door and / or during positioning travel of the door in the area of the
end positions by up to 50% is possible. It is essential to also check the
current consumption of the motor during the reference run!
The following applies: The higher the ED / actuation frequency, the
lower the value of an exceedance of the rated current indicated on the
motor should be.
In case of discrepancies of the indicated current value (e.g. with 0.18
KW MultiMove nominal value 1.3 A, actual motor current permanently
1.7 A) consult Dictator Technik.
