15.3.3 CT and SA connection check
If installation of the PR113 was carried out by the user, at the time the trip unit is turned on for the first time, it is advisable
to check the first line of the display. No messages of CTs and/or SA disconnected must appear, otherwise immediately open
the power circuit breaker and make the correct connections.
15.3.4 Test
Before putting into service, it is possible carry out a test by means of the specific “Self-test” function which
can be activated on the PR113. A positive result is visible and shown on the display.
Following this, it is possible carry out, still using the specific function (Trip test), testing of the whole
SA chain. A positive result is given by the power circuit breaker opening.Check, on the same
“PR113 Tests” screen the open or closed status of the power circuit breaker, checking “CB Status”.
15.3.5 Initial settings
If the PR113 is supplied directly installed in the power circuit breaker it is up to ABB SACE to set all the
variables referring to the power circuit breaker or to the specific application correctly (e.g. Type of power circuit breaker, CT size, network frequency
…). Vice versa, if the PR113 is supplied as a loose piece, it will be up to the user to set all the necessary parameters correctly.
It should be noted that ABB SACE defines each possible setting in a sensible way (see default parameters ).
Apart from this, it is absolutely indispensable for the user to modify the password and carefully define each modifiable
parameter, before putting the PR113 into service.
15.3.6 Password management
Password? [0***]
To enter “edit” mode it is necessary to enter a four-figure numerical password.
Select the value of the first figure ( between ‘0’…’9’ ) by means of the
↑
and
↓
keys and press
↵
to confirm the figure and pass on to entering the
next one.
After entering the fourth figure, check the password entered. If the password is correct, you pass from the “READ” mode to the “EDIT” mode (at
this point the first field which can be edited on the page is displayed in reverse).
In the case of an wrong password, the message following message appears
Wrong password
which remains until the ESC key is pressed (or after 2 minutes).
It is also possible to interrupt the operation during entry of the password by pressing the ESC key.
The password is valid for a maximum of two minutes from the last time a key was pressed. It is immediately reset in the case of a high priority
alarm or when the unit is reset.
On entering a page without modifiable parameters, the state of the protection is put on “READ”. If the password is still valid, to enter “edit” mode
(on a page with modifiable parameters) simply press the key
↵
.
Disabling the Password.
By setting the value of the password to [0000] (in the “Unit configuration” menu) the request for password is disabled. Passing from “READ” to
“EDIT” is therefore always possible.
To enter a new password, select “Set Password” from the “Unit Configuration” menu.
