31 CONTROL MECHANISM. FEATURES.
Start-up Reset:
Reset before the first normal operation of the table.
Manual Reset (Initialisation):
Simultaneous pressing of key combination (UP and DOWN keys) on manual
switch triggers a reset.
Power failure Reset :
In case of a power failure during operation, reset before re-using table normally.
Reset operation:
Reset operation is conducted with reduced power (speed).
Maximum ON time:
The electronic system monitors on-time duration. In case of exceeding maxi-
mum time limit, the electronic system blocks further drive operation. This is
a way to protect the power supply unit, the control mechanism and the drives
from overloading.
Safety disconnection:
Both the power supply unit and the control mechanism switch off automatically
in case of overheating.
Safety limit:
The system defines a certain range (approx. 90 mm from lower end position)
as a safety limit. Upon reaching that limit, the drives stop and can be activated
again at reduced speed by again pressing the key. Before effecting a downward
movement within the safety range - and if the previous movement was upward
- the UP key must be pressed twice.
Overload recognition:
The control mechanism shuts off as it recognises table overload by excess
weight.
