3. INSTALLATION AND START-UP

The manual you hold in your hands contains information and warnings that the user should respect in order to guarantee a proper operation of all the instrument functions and keep its safety conditions. The instrument must not be powered and used until its definitive assembly on the cabinet’s door.

Whether the instrument is not used as manufacturer’s specifications, the protection of the instrument can be damaged.
When any protection failure is suspected to exist (for example, it presents external visible damages), the instrument must be immediately powered off. In this case contact a qualified service representative.

3.1. Installation

Mounting

Instrument is to be mounted on panel. All connections keep inside the cabinet.

Note that with the instrument powered on, the terminals could be dangerous to touching and cover opening actions or elements removal may allow accessing dangerous parts. Therefore, the instrument must not be used until this is completely installed.

Notes:
Input signal: BJ195-X Series using a separate acquisition calculate for each measurement channel, to ensure consistent in use, for different load forms, it’s a variety of connection mode. Access wire shall be met 2.5 square mm.

A. Voltage input
Input voltage should not exceed the rated input voltage products 450V, Otherwise, you should use external VT. Suggest 1A fuse be installed in the voltage input side.

B. Current Input
Standard input current is 5A or 1A, if greater than 5A/1A should use external CT.
When the CT is connected with other meters, make sure wiring methods be used in series.

Warming: Forbid to install a CT on the live feeder wire with open secondary leads. This can be extremely dangerous!

Before remove the current input connection, must be sure to disconnect the primary circuit or shorted secondary circuit of CT.

C. Sequence of wire
Warming: Please make sure that the input voltage and current corresponding to the same phase, sequence, and the same direction; Otherwise, the Values and symbols will be wrong! (Power and Energy)
Always observe the physical orientation of CT (P1 – P2) when installing on the feeder wire. Always pay attention to wiring polarity and phasing when terminating the CT leads to the BJ195-X Series. S1 connect to Ix*, S2 connect to Ix.

The input network configuration of instrument depends on the CT number of the system: in the condition of 2 CT, select the three-phase, three-lines two components;
in the condition of 3 CT, select the three-phase, four-lines three component mode.
Instrument connection mode, set of the instrument (programming input network NET) should be the same load wiring as measured wiring. Otherwise, the measurement instrument will lead to incorrect voltage or power.

In three-phase 3 wire mode, measurement and shows the line voltage;
In three-phase 4 wire mode, measurement and shows phase voltage and line voltage both.

D. Auxiliary power
BJ195-X Series with universal (AC / DC) power input, if not for a special statement, we provide the 90-240AC/DC power interface for standard products, please ensure that the auxiliary power can match with meter to prevent unexpected damage.

A. Suggest install 1A fuse in the fire line side.
B. For the areas with poor power quality, suggest install lightning surge suppressor and rapid burst suppressor to prevent lightning strikes.

4.- OPERATION MODE

The instrument has three line displays. Every led will be on according to the parameter presently shown in screen.
When the 195-X is powered up, all the LED indicator will on, and meter start self- test, after some seconds, the meter is ready for operation and shows one of the available screens.

Parameters on display can be switched by pressing key on screen at any moment
When the key  is pressed, the screen CURRENT values of each phase are now showing.
In setting menu, pressing key can move the setting cursor to left; Pressing can enter the number O – 9.

Pressing it can open the setting menu and return to previous menu. In setting menu for change number 0-9 (only for 48*48 size meter)

Pressing this key, you can exit it with saving any modification that you might have done, in menu operation press “Enter” key, and user can go to the next menu.

Note:
Press in normal standby status, and the meter will show different data in main screen:
In the menu set mode, when changes the parameter and exit setting, the meter will ask to “SAVE”, press exit without saving press save and exit.

5. SETUP PROCEDURE

The SETUP procedure of the BJ 195-X is performed by means of several SETUP options. Once into the SETUP, use the keyboard to select different options and enter required variables:

If meter have Ethernet port, that configuration under “Bus” menu will change to following:

Note:

The procedure above is for reference, not all series have the step 3 (communication preference), AO menu for D series have this function, bUS menu for K series, please contact the Technical Service.

6. COMMUNICATION INTERFACE

6.1. Connection for the RS485 BUS

The composition of the RS-485 cabling must be carried out with a meshed screen cable (minimum 3 wire), diameter of not less than 0.5mm2, with a maximum distance of 1,200 m between the BJ-19 … and the master unit. This Bus may connect a maximum of 32pcs BJ-19 ….

Notes:

• For communication with the master unit, user can choose RS-485 to RS-232 converter or RS485 to USB adapter to use.
• For expand the number of devices in the communication network, a signal repeater can be used.
• Full range of BJ-19 … meter RS485 PIN number is 58,59,60
• Due to product modifications or special requirements, the interface pin place may be change. For details, please refer to product label on the rear side

6.2.- MODBUS © Protocol

Modbus RTU Frame Format:

MODBUS FUNCTIONS:

Note: Float data follow IEEE754, float low bit first, high bit next. (CD AB) Only read parameter, can be read with “03” command

7.- SAFETY CONSIDERATIONS

All installation specification described at the previous chapters named:

INSTALLATION AND STARTUP, OPERATION MODE and SPECIFICATIONS.

Note that with the instrument powered on, the terminals could be dangerous to touching and cover opening actions or elements removal may allow accessing dangerous parts. This instrument is factory-shipped at proper operation condition.

8. MAINTENANCE

The 195-X does not require any special maintenance. No adjustment, maintenance or repairing action should be done when the instrument open and powered on, should those actions are essential, high-qualified operators must perform them.
Before any adjustment, replacement, maintenance or repairing operation is carried out, the instrument must be disconnected from any power supply source.
When any protection failure is suspected to exist, the instrument must be immediately put out of service. The instrument’s design allows a quick replacement in case of any failure.
