D) Now carry out a test with the door disconnected from the motor, making it open and close, and press the STEP-BY-STEP button
to verify that the mechanical parts are all in good working order. (Door OPEN is the first manoeuvre after power is turned back on.)
When the cycle has finished hook the door back on the chain.
E) It is now time to position the elements sliding to the limit switch.
Press and hold down the STEP-BY-STEP button and verify that the door
moves in the opening direction. If the door is stuck, turn the "OPENING
FORCE" trimmer clockwise with a screwdriver (see Fig. 4) to increase
maximum opening force. Keep the button pressed until the door is 1 cm from
the opening point; now fit the sliding element next to the casing's edge. Now
press and hold down the STEP-BY-STEP button once again and verify that
the door moves in the closing direction. If the door is stuck, turn the
"CLOSING FORCE" trimmer clockwise with a screwdriver (see Fig. 4), to
increase maximum closing force. Keep the button pressed until the door is 1
cm from the closing point and then fit the sliding element next to the casing's
edge.
F) It is now possible to try a complete movement of the actuator. Press and hold
down the STEP-BY-STEP button until the door stops automatically at the end of its travel. Press the STEP-BY-STEP button once
more until the door stops automatically at the end of its travel in the other direction. We suggest making the door open and close
several times to see if there are any assembly or adjustment defects of the gearmotor's limit switches or if there are any points of
friction.
G) It is now time to test triggering of the safety devices connected to the PHOTOCELL input: they have no effect in the opening
manoeuvres while they cause the door to stop when it is closing and they also cause reversal of movement when in the semi-
automatic and automatic functioning modes. The devices connected to the STOP input work in both the opening and closing
manoeuvres, stopping movement.
H) Now select the functioning mode (see Fig. 2) with the dip switches, going from hold to run control to semi-automatic or automatic
as required by the customer.
3.1) ADJUSTMENTS:
After the system has been checked it should be adjusted to guarantee the proper working order of the automation and to ensure a
correct and safe operation.
The recent European standards, prEN 12453: safety in the use of motorised doors - requirements and classifications; and prEN
12445: safety in the use of motorised doors - testing methods; (not completely approved), require the use of measures to limit the
forces in the movement of automatic doors equal to a maximum of 1400N as the impact force; a maximum static residual force of
150N that must cancel itself out within 5 seconds from impact.
✓ There is a system on the unit that constantly controls the
force developed by the motor. If it exceeds a certain level,
adjustable with the trimmers, a safety device stops and
reverses movement immediately. There are two different
adjustments to be made as the force needed for opening may
be different to that needed for closing, especially if the door is
not well balanced.
Now adjust with the trimmers (Fig. 4) to reach the values
specified by the above mentioned standards.
Broadly speaking, the adjustment has to ensure a manoeuvre
without the safety devices triggering due to normal mechanical
friction but, at the same time, the manoeuvre should stop at
the slightest pressure exerted in the opposite direction.
