STRING WORKS EE Series User Manual page 15

If the table cannot be raised or lowered, check the cable connection between:
• the power supply and the outlet
• the power supply and the control unit / ECS+
• the handset and the control unit / ECS+
• the columns/motors and the control unit /ECS+
If the table still doesn't operational, the control system may have triggered the overhea-
ting or duty cycle protection. Unplug the power cable and wait for at least 9 minutes and
try again fore proceeding.
If a control unit is replaced, a manual reset is required. Follow these steps as section 3.2.
If the table is still not operational, please contact your vendor for further assistance.
The control system is equipped with safety features; the intermittency function and the
overheating protection and memory function
Overheat protection – The table will become inoperable if the overheating protection
is triggered and will return to operation automatically once the heat has dissipated suf-
ficiently. If heavy loaded and driven continuously for a long period of time the motor
might get very hot. The software observes this and if overheated system will shut down
and you will have to wait about 9 minutes before being able to run again.
Memory function – The control system / ECS+ (each column) will retain information re-
garding the elevation of the table at all times. This information will remain stored even in
case of power failure or if the power cable is disconnected from the power outlet.
Overload protection – If the total load on the equipment is to high you will only be able
to drive for a short moment. The system will then stop and you need to release the table
from load. Press button again.
Anti collision (optional) – The ECS+ can be equipped with an intelligent software pinch
protection. During low ration the currents to each connected motor is continuously mea-
sured and any variation of current is evaluated about 50 times each second. If a collision
is detected the system will stop and back off about 1 inch (25 mm).
IMPORTANT! Make sure to remove the blocking item causing the pinch before trying to
operate the table again. Failure to do so may cause injury to user or equipment.
Soft start – Progressive acceleration allows for soft starts and stops.
Speed – the speed of the table varies with load.
