While in Service Engineer access mode, any additional parameter can be added to the MMSP parameter regis-
ter. Action:
- with DOWN and UP buttons choose the parameter to be added;
- push buttons DOWN and UP simultaneously.
To exclude a parameter from the MMSP register:
- with DOWN and UP buttons choose the parameter to be excluded;
- push buttons DOWN and UP simultaneously.
When a parameter is excluded form the MMSP mode register, a decimal point glows in the higher digit position
- push buttons DOWN and UP simultaneously.
To exclude a parameter from the MMSP register:
- with DOWN and UP buttons choose the parameter to be excluded;
- push buttons DOWN and UP simultaneously.
When a parameter is excluded form the MMSP mode register, a decimal point glows in the higher digit position
of the mnemonic indicator.
2.2.6 Restoring factory settings.
There are two ways to restore the factory settings.
Way 1. Set up parameter
Way 1. Set up parameter
=1. Upon exit from the parameter setup mode all factory settings will be restored
(except the Service Engineer Password).
Way 2.
When powering ОМ-310 on, hold down SETUP and RES/MEM/SEL buttons for 2 seconds. All factory
settings including the Service Engineer will be restored (Service Engineer password – 123).
After completion of the factory settings setup, ОМ-310 will start operation in MMSP mode, which includes the
following parameters:
- CT type (external or integral);
;
- CT rated current (set in case of external CT);
;
- rated power of load,
.

2.3.1 When operating with load power ranging from 3 kW to 30 kW, use of built-in current transformers is al-
lowed. The mains leading to the load must be conducted
through openings in ОМ-310 casing (each phase wire
uses a separate opening).
When using other capacity loads, current transformers with 5A rated output current shall be connected in accor-
dance with Fig 2.1. For correct OM-310 operation, the current transformers’ polarity must be observed.
2.3.2 Run all three power phase cables through differential current transformer (zero sequence transformer)
and connect the DCT to ОМ-310.
2.3.3 Connect ОМ-310 to power mains in accordance with figure 2.1.
2.3.4 To opera
2.3.4 To opera
te ОМ-310 via PC as control or monitoring device with use of “ОМ-310 Control Panel” software:
-
install “ОМ-310 Control Panel” software to your PC by running setup_UBZ314.msi application;
-
connect “ЭВМ” (PC) connection plug on ОМ-310 front panel to RS-232 plug on PC with use of KC-01 cable
or to USB jack of PC via KC-USB-01 cable;
-set parameter “
=1”.
N o t e 1 - “setup_ UBZ-
ОМ.msi” software can be downloaded from Novatek-Electro website
N o t e 2 -
КС-01, KC-USB-01 cables are optional and can be ordered separately. Users can make KC-01 cable
themselves following the diagram shown in Fig. 2.2.
N o t e 3 - Custom-developed softwa
re can also be used to operate ОМ-310 .
2.3.6 When using MODBUS, connect communication lines to terminals 33, 34, 35 of. Set “
=2” parameter.
2.3.7 Energize
ОМ-310.
N o t e -
ОМ-310 is supplied with rated load power set equal to zero. In this case the ОМ-310 load relay
will not close before the rated load power is set up.
Load relay closing sequence is controlled by
и (par. 2.4.1.) parameter values.
2.3.8 Set up required parameter values in the menu.
2.3.9 De-energize
2.3.9 De-energize
ОМ-310.
2.3.10 Connect the load magnetic contactor (further referred to as MC) according to Fig 2.1.
N o t e - When the load relay is energized, contacts 5-6 and 8-9 are closed, when the relay is de-energized,
contacts 4-5 and 7-8 are closed.
