ОМ-310
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
of the mnemonic indicator.
2.2.6 Restoring factory settings.
There are two ways to restore the factory settings.
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 OM-310 PRE-OPERATION PROCEDURE
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
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
(http://www.novatek-electro.com/production_ubz.htm).
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
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.
