Description
Problems with the transfer of device parameters from
one protection device to another of the same type (e. g.
EDR‑5000).
All parameter changes are refused with the message
"Please wait
System locked".

Information
You have configured the parameters of an E-
Series device. Now you want to transfer these
parameters to another device. This is possible
if both devices are of the same type, e. g.
EDR‑5000.
All parameter changes, including the transfer of
parameters to a protection device, are refused
with the message "Please wait
System locked" on the device´s display (or a
comparable message by PowerPort-E) – The
protection device is locked against parameter
changes.

4 Problems with the Device
Corrective Action
Read out the device parameters with PowerPort-E from
the first device. Save them into a file.
Now reopen this file with PowerPort-E. Adapt the settings
to the order code of the second device by selecting
[Edit / Modify Device Configuration (Typecode)...].
Select »Apply«. By this the existing parameter file is
being converted to the format of the second device.
Now there may be implausible parameters. These are
marked with a question mark and are not valid for this
device type. Please adapt the values of the implausible
parameters. Afterwards you can transfer the parameter
settings to the second device.
There are two potential reasons why parameter changes
might be locked:
•
• An intentional setting lock has been activated
by assigning a signal to [System Para / General
Settings] »Program Mode«.
The setting lock is released as soon as the assigned
signal becomes "Inactive". If it is not possible
to set that signal inactive you can temporarily
bypass the setting lock at [System Para / General
Settings] »Program Mode Bypass«.
•
• A switching operation is ongoing (or at least
the protection device believes this). In general,
parameter changes are refused during a switching
operation.
Switching operations should last only for a short
time. So, if setting changes are refused for a long
time you should check the Event Recorder whether it
lists a continuous series of switching operations.
If this is the case then you should check the auxiliary
contacts that are used for position indications. There
might be a bad contact, or the corresponding Digital
Input might be configured to a wrong voltage level.
In either case there can be a chattering of the input
signal, which causes the protection device to be
flooded with signals of switching operations.
