Models SU2000 – SU2010
Pull the knob downwards to position 1.
Move the door by hand. (Figs. 16 - 16a)
The release device must only work when the door is stopped.
To programme and adjust anti-squash torque, please see the
instructions of the A924 control unit.
4) Manual manoeuvre or release
The whole system must be tested by qualified and expert staff who
must perform the tests required, according to the level of risk.
To test SUMO, proceed as follows:
• close the door;
• disconnect the power supply from the control unit;
• release the gear motor;
• check that the slide way is clean and free from debris;
• completely open the door manually making sure to exercise a force
always less than 300N (30kg);
• check that the door does not stick when moving;
• check that when the sectional door is stopped at any point it
remains motionless;
• check that the safety system and mechanical stops are in good
condition;
• check that the screw connections are perfectly tight;
• check, where present, that the chain is taut and that it slides well,
lubricate if necessary.
• after the above checks, block the gear motor and power the
control unit.
• adjust (from the electronic control unit) the force of the actuator so
that it can move just the door;
• measure the force of impact as required by EN12445 and
EN1245353 standards.
5) Testing
The A924 control unit features a maintenance LED (see the
instructions handbook for the A924 electrical power unit for further
information). This signals when routine maintenance operations are
required. Not only does regular maintenance offer longer life, but also
correct and safe system operation.
Maintenance may only be performed by qualified staff.
Maintenance involves repeating the test procedure.
6) Maintenance
6.1) Disposal
SUMO comprises various types of materials which must be disposed
of in compliance with the laws of the country of installation.
There are no particular dangers or risks deriving from demolition of
the system.
If waste sorting is required, the components should be grouped by
type of material (electrical, aluminium, plastic, etc.).
