7.20 Disposal and returns
The lifting column must either be disposed of according to the applicable policies and regulations,
or returned to the manufacturer.
The lifting column contains electronic components, leads, metals, plastics, etc., and must be dis-
posed of in accordance with the applicable environmental regulations for the country in question.
In Germany, disposal is governed by the
Elektro-G
(RoHS) [Electrical Code] and in the European
[Economic] Area by EU Directive 2002/95/EC or the relevant national legislation.
Indication
Fault
Fault rectification
E900
Communication between inter-
connected control units is faulty.
Pull out the mains plug, check the connections and per-
form an initialisation run (see section 7.12).
If the error is still indicated, check the Slave control units
for fault
E920
(see below).
E910
(Master
only)
The number of slave controls
detected does not correspond with
the parameter 123.
Check the connecting cable and the value set in parameter
123. Then start the initialisation run on the master control.
E920
(Slave only)
A Slave control unit has detected a
position difference in comparison
to the Master control unit.
If the fault
E900
occurs even after checking the lead and
connections, plug the hand switch into the Slave control
units sequentially. If the fault
E920
is indicated, there is a
position difference between the corresponding Slave con-
trol unit lifting columns and the Master control unit lifting
columns.
Perform an initialisation run.
E90x
(Master only
The x slave control has reported an
error. For example, E901 stands for
the 1st slave control.
Check the error message on the slave control and continue
according to the error message.
CANS
(Slave only)
An attempt is being made to start
an initialisation run on a slave con-
trol.
If the control is located in a bus system, restart the initiali-
sation run on the master control. Otherwise you will initi-
ally have to set the parameter 113 to "0".
