6.1
Maintenance
Within the usual maintenance works, the following checks are to be carried out:
a)
General visual check concerning possible dust deposits.
b)
The correct fastening of the connections of the control device has to be checked.
c)
Possibly check /STATISTIC/STAT0 in the error storage if troubles have occurred since the last
maintenance has been carried out.
6.2
Troubleshooting
Because of the digital construciton of the control device, numerous possible causes of trouble are already
displayed as clear text. In general, it is possible to find the cause by means of these messages and by
using the explanation given in appendix
A4
as well as in the error search plan
A5
.
The following procedure is recommended:
a) If a trouble occurs (display blinks, error text
and number are displayed), you have to look
up the general error explanation in A4.
b) If no trouble is directly displayed by the
control device, you have to check in the error
storage /STATISTIC/STAT0 whether an error
has occurred since the last maintenance has
been carried out. The entry first displayed is
the error that occurred last.
In order to save costs and money for queries, the questions in appendix A9 have to be answered before
phoning the
ZIEHL-ABEGG HOTLINE
6.3
Repair
When removing the front plate of the control
device, the warranty period granted by the
manufacturer lapses. The removal of the front
plate is only possible after having asked the
manufacturer.
If an error in the control device can be proved, it
is not recommendable to repair the device
locally because of economic reasons.
We recommend elevator services to have a
replacement device with the biggest controller
size ready. In case of trouble, you have to carry
this device with you. But if you are not sure
whether the control device is really the cause for
the trouble, this can be found out when quickly
replacing the control device (4 fastening screws,
9 locking screws and 6 edgeboard connections).
Manufacturing companies or high-lift stocks
(with several production streets) are
recommended to have a control device of the
biggest construction on stock.
After commissioning, all possible parameter lists
of the devices to be possibly replaced are to be
added to the control device.In case of production
spots of particular importance ("Bottleneck"), it is
recommendable to preset the parameters of the
replacement device to this function.
In the documents TIA94-21, the error search as
well as the repair of individual components is
explained as a help. These documents also
include a list of the replacement parts that are
possibly needed.
