Important Notes; Preliminary Checks - GILGEN AS-844 R Assembly And Operating Instructions Manual

1.1 Maximum duty cycle curve
The curve makes it possible to determine the maximum operating
time (T) with respect to the duty cycle (F).
Example:
The AS-844 R drive unit can work continuously at a duty cycle of
50 %.
To ensure smooth running, operation should be kept within the
duty area under the curve.
Note:
The curve was plotted on the basis of operation at
a temperature of 24 °C. Allow for up to 20 %
reduction of the duty cycle in case of exposure to
direct sunlight.
Calculating the duty cycle
The duty cycle is the percentage of the actual operating time
(opening plus closing) compared with the total time of the cycle
(opening plus closing plus pause time).
The formula for calculating: % F =
Ta = opening time
Tc = closing time
Tp = pause time
Ti = interval between a complete cycle and the next

Important notes

· The installer must provide the user with all information related
to the release system in case of emergency and hand over to the
end-user this instruction booklet which is attached to the product.
Warning:
Switch off power supply before performing any
work on the electronic control unit!
Check that up-line to the electrical system there is
a differential switch with a trip threshold of 0,03 A.
In case of breakdown and/or malfunction the user
must avoid any attempt to repair or adjust the
automation personally and only contact a qualified
specialist.
· Read these instructions carefully before installing the gate
automation system. Keep these instructions for future reference.
· Installation and electrical wiring must conform to current
standards.
· Install a multi-pole switch with a contact spacing equal or over
3 mm on the mains supply line. In alternative the use of a 6 A
thermo-magnetic breaker with multi-pole switching is
recommended.
· The manufacturer accepts no responsibility for damage or injury
resulting from the incorrect use of this drive unit.
3 Installation of the drive unit
3.1

Preliminary checks

To ensure trouble-free operation, make sure that the gate (whether
existing or yet to be installed) has the following specifications:
· Max. gate weight 1'800 kg.
· Strong and rigid leaf frame.
· Flat leaf face, with no protruding parts and no vertical members.
· Smooth and even movement of the leaf over its entire travel.
· No sideways oscillation of the leaf.
· Upper and lower sliding system in perfect condition (the use of
floor tracking with a rounded channel is to be preferred, because
it reduces friction in the sliding movement). Self-supporting gate
types are also an ideal application.
· Only two slide wheels.
· Mechanical safety stops to avoid risk of derailment; they must
be firmly fixed to the ground or to the floor track, about 20 mm
beyond the travel limit.
· No mechanical lock.
If any welding or brazing is required on the gate, it should be done
before installing the drive unit.
The condition of the structure directly affects the reliability and
safety of the drive unit.
