2.2.2 Disabled keypad mode
When keypad is locked, viewing and resetting programmable parameters is not possible.
When keypad is locked, pushing SETUP button will result in LOC message display. To unlock the keyboard the
SETUP button shall be pressed again. The "SETUP" LED lights up, and figure "0" is blinking on the indicator. With
the UP and DOWN buttons user enters a password digit from 1 to 9 and presses the RECORD/RESET/SELECT
button. If the password is correct, the keypad will be unlocked. If after the keypad was unlocked no button is
pressed during 15 sec and the lockage setting is not released by user, the keypad will relock.
The unblocked keypad allows:
- to operate in MMSP mode;
-
to change and to view the user level parameters;
-
to view the service engineer level parameters.
2.2.3 MMSP – mode with minimum number of setting parameters
MMSP is devised to ease the service personnel’s operations with ОМ
-310.
To employ MMSP mode in OM-310, the user needs to set
=1 parameter, or perform resetting to factory set-
tings. (2.2.4). When ОМ
-310 unit is in this operation mode, green LED
“
MMSP
”
is on.
In MMSP for normal activity of OM-310 is enough fix parameter
(nominal active power table 1.5 if necessary
parameters
(time where through loading relay will be switched OFF after of energy input exceedence of main
thresholds table 1.5) and
(time interval of cut off loading relay on energy input exceedence of main threshold
table 1.5)
On duty of external TT is necessary to fix following parameters:
-type of TT (parameter
, table 1.5) external;
-nominal current of TT (parameter
, table1.5).
The difference between MMSP mode and the user mode is that the parameters not included in the MMSP regis-
ter are set to default factory values.
ATTENTION! If some programmable parameters have been modified by the user or service engineer, but
not included in the MMSP register, switching to MMSP mode will reset such parameters to factory settings.
The parameters included in this register cannot be viewed or modified. Operations with the MMSP register pa-
rameters are similar to the user level operations.
Adding parameters to the MMSP register and MMSP mode disabling is possible only in service engineer
access mode.
When switching off the MMSP mode (setting
parameter
=0) LED “MMSP
” goes off. In the user mode all
parameters list is displayed, but to change a parameter, parform the following:
- with DOWN and UP buttons choose the parameter to be added;
- push buttons DOWN and UP simultaneously.
2.2.4 User level
To view and to change the user level parameters one needs to press the SETUP button, then "SETUP" LED will
glow. Scroll parameters with DOWN and UP buttons, enter parameter change mode – repeat push SETUP button
(the parameter value starts to flicker), change parameters – with DOWN and UP buttons, record parameter -
RECORD/RESET/SELECT , to return to menu without change – press SETUP button again. If no button is pressed
during 15 sec the
ОМ
-310 will transfer to the initial state.
If a parameter change is forbidden (a dot in the middle digit field of the parameter mnemonic indicator glows),
then the parameter change is possible only in Service Engineer level after the prohibition has been released.
2.2.5 Service Engineer Level
Access to the Service Engineer level.
Push SETUP button and hold for 5 sec. If the level is protected by a password, the label PAS appears on the
indicator. The "SETUP" LED lights up, and indication "000" flickers on the parameter value indicator. With the UP
and DOWN buttons enter the three-digit service engineer password, digits from 1 to 9 and separate dialing with
pressing the RECORD/RESET/SELECT button. If the password is incorrect, the PAS label lights on blinking in the
higher position of the value indicator, and ОМ
-310 goes back to the initial state after 15 sec, otherwise the first pa-
rameter of the service engineer menu appears on the indicator.
Scroll parameters with DOWN and UP buttons, enter parameter change mode – repeat push SETUP button (the
parameter value starts to flicker), change parameters – with DOWN and UP buttons, record parameter -
RECORD/RESET/SELECT , to return to menu without change – press SETUP button again. If no button is pressed
during 1
5 sec the ОМ
-310 will transfer to the initial state.
While ОМ
-310 is in Service Engineer mode, the decimal point in the lower digit position of the mnemonic indica-
tor is on.
In the Service Engineer level the access to any user level parameter can be prohibited or permitted by simulta-
neous the SET and DOWN buttons pressing. Access denial is indicated by decimal point in the middle digit position
of the mnemonic indicator.
