13.15.2 Modification of parameters
In the case when the operator wants to carry out data readout or configuration operations, simply press the ESC key and the page relative to the
main menu will automatically be displayed:
1. Config./Program
2. Ammeter
3. Test
4. Other functions
Now, with the
↑
(up arrow) or
↓
(down arrow),
↵
and ESC keys it is possible to move around inside the main menu and reach all the pages relative
to the configurations and parameterizations to display or modify the parameters set.
On completion of a programming operation, press the
↵
key to accept the new configuration (Accept prg) or press the ESC key to refuse it and
therefore keep the old configuration (Undo prg).
The following will therefore appear:
Accept prg: <ENTER>
Accept prg: <ENTER>
Undo prg: <ESCAPE>

NOT stored
These pages indicate whether data storage has been successful or Not.
In the latter case, the PR112 unit will use the last valid configuration set.
13.15.2.1 Modification of basic configuration
If the PR112 unit is in an alarm situation no parameterization is allowed.
The basic configuration of the unit must be carried out in EDIT mode.
Following what is given under the chapter. 13.12 show the following on the display:
Language : xxxx.
PR020/K unit : xxx
Net Frequency: xxHz
Neutral sel. : xxx%
Set Password: [****]
OverTemper.Trip: xxx
Min.Unbal.Phase: xxx
K51/pL : xxxxxxxx
Select the language to be used to display the messages
Indicate whether the accessory PR020/K unit is present
Select the Nominal Frequency value for operation of the installation
Select the setting value relative to protection of the neutral conductor (percentage expressed according to the
phase current).
Programming a new password in EDIT mode. The successive messages are :
New Password:
→
[****] e Confirm PSW :
→
[****] for confirmation
Select enabling or disabling of power circuit breaker opening in the case of the second temperature (85°C)
threshold being exceeded. Select the minimum unbalance value of the currents between phases
Select which information to combine with signaling by means of the K51/pL relay.
The possible selections are given in the table of par. 13.11.1.
Select the type of protection against ground fault: select [Int ] if you want to protect the installation with the help
of the internal toroid, otherwise [Ext ] if you want to protect it with the help of the external toroid by carrying out
the “Source Ground Return” protection function. (This selection is only displayed in the LSIG version)
Select the value of the continuous current rating of the external toroidal transformer for the “Source Ground Return”
function.
Select the type of EMAX power circuit breaker (code and continuous current rating) which the PR112 unit is
mounted on The possible selections are available in the technical catalogue.
Select the value of the continuous current rating of the current sensors (CS) mounted on the power circuit breaker.
N.B.:
Incorrect configuration of “In” does not in any way jeopardize perfect functionality of the protections.
The only problem will be incorrect display of the absolute value of the Currents.
