UBZ Indicator in view mode of measured and calculated parameters (load relay is on)
In the second and third variant, information of the fourth line of the indicator is consistently changing
–
in addition
to reports about the possibility of starting the motor; it displays the total number of faults and type of fault on the
display (Fig.5.4). For example, if the information on the indicator corresponds to Fig.5.4, then in 2s the fourth line
displays the fourth type of fault.
The display shows:
–
In line 1
–
line voltage U1
–
345 V;
–
In line 2
–
line voltage U1
–
312 V;
–
In line 3
–
line voltage U1
–
210 V;
–
In line 4
–
"Imax"
–
type of fault (over-current protection); "Er 3:8"
–
the indicator displays the third fault; total
number of existing types of faults is 8.

5.2.3 Mode of
‘
Keyboard blocking
’
When the keyboard is blocked you cannot view and reinstall the programmable parameters.
When the keyboard is blocked, pressing the
SETUP
button leads to the appearance on the indicator the
message “

Indicator when the keyboard is blocked
To unblock the keyboard, it is necessary to press again the
SETUP
button. The led turns on
SETUP
, and the
indicator displays the inscription
“USERS PASSWORD”
and
“<0>”.
With the help of
UP
and
DOWN
buttons you can
dial the digit of user password from 1 to 9 and can press the button
RES/MEM/SEL
. If the password is correct, the
keyboard is unblocked. If after unblocking the keyboard no button is pressed within 15 s and setting of blocking has
not been disabled by the user, the keyboard is blocked again.
5.2.4 Mode of
‘
Minimum number of settings
’
(MNS)
Mode of
MNS
is designed to facilitate the work of the service personnel with UBZ.
In case of initial factory settings UBZ is in the mode of
MNS
.
When UBZ is operated in the mode of
MNS
the green led
MMSP
is on
.
UBZ operation in
MNS
mode differs from UBZ operation in the mode of user level that the parameters not
included in the list of
MNS
are set to factory defaults, and when you log in the user menu they are not visible.
Operation with parameters those are included in the list of
MNS
is the same as with the settings in the mode of
user level (it.5.2.5).
When the mode of
MNS
is disabled (setting of parameter "Minimal set" is in "Off" position), the led
MMSP
goes
out and UBZ switches to the user level. At the user level you can change all the settings (included and not included
in the list of
MNS
), if the change is not disabled by the advanced user.
ATTENTION: If any programmable parameters have been changed by the user or the advanced
user (at user level or advanced user level modes), but they are not included in the list of MNS, then
when transfer to the mode of MNS instead these changes the factory settings will be restored.
Adding of any parameter in the list of MNS and disabling of MNS mode is possible only in
advanced user
level.
UBZ will transfer to the
MNS
mode after reset to factory settings (it.5.2.7).
5.2.5 Mode of
‘
User level
’
When UBZ unit is in the user-level mode, led
MMSP
is off.
To view and change the parameters of user level you should press the
SETUP
button, the led
SETUP
is on and
the indicator displays the user menu (Fig.5.6).
