4) Manual manoeuvre or release
EN
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.
The whole system must be tested by qualifi ed 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.
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 qualifi ed staff.
Maintenance involves repeating the test procedure.
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.).
