4.- INSTALLATION AND START-UP

The manual you hold in your hand 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 on and used until its definitive assembly on the cabinet’s door.

If the instrument is not used as manufacturer’s specifications, the protection of the instrument will 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.

4.1.- Installation

Mounting

Instrument is to be mounted on panel (cut-out 91+0.8 x 91+0.8 mm). 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: BJ194E 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.

A. Voltage input:
Input voltage should not exceed the rated input voltage products (1 00V or 400V), Otherwise, should use external CT, the input voltage to be installed in the 1A fuse.

B. Current Input:
Standard input current is 5A, if greater than 5A should use external CT.
Even if you are using on the CT are connecting with other instruments, wiring methods should be used in series. Before remove the current input connection, must be sure to disconnect the primary circuit or shorted secondary circuit of CT. Suggest using the terminal block, please not directly connect to CT, in order to facilitate disassembly.

C. 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 wrong!! (Power and Energy)

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 three-wire mode, the measurement and shows the line voltage;
In three-phase four-wire mode, the measurement and shows the phase voltage.

Auxiliary power:
BJ194E Series Power Meter with universal (AC/ DC) power input, if not for a special statement, we provide the 220VAC/DC or 11 0VAC/DC power interface for standard products. Instruments limit work power supply: AC / DC (80-270V), please ensure that the auxiliary power can match for BJ 194E series meter to prevent damage to the product.

A. Suggest install 1 A 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.

7 .4.1. – Meter communication address setting

One or some BJ194 … meter can be connected to a P.C. With this system we can get all the parameters in one central point of reading. The BJ194 … , has a serial RS-485 or RS-232 type output (according to the model). If we connect more than one device to the same communication line (RS-485), we have to assign to each of them a different code or direction (from 1 to 247), since the P.C. needs the identification of every measuring point.

7.4.2.- Communication Baud rate setting

8. – SAFETY CONSIDERATIONS

All installation specification described at the previous chapters named:
INSTALLATION AND STARTUP, INSTALLATION MODES 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.

9. – MAINTENANCE

The 194E 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.

10. – TECHNICAL SERVICE

FAQ’s

1. The BJ-194E Power Meter, once cabled and connected is seen to give a correct voltage and current reading, but shows negative values for active power (generation).
   This is an error with the cabling for the current transformer secondary; the direction of the transformer current has to be respected as shown in the connection diagram. The current transformers have a two face primary; the current must pass from P1 to P2 giving the result in secondary (S1 and S2) of 5 amps.
   The error stems from:
   a). The current transformers have been incorrectly installed. As a result it gives the direction of the current as passing from P2 to P1; to resolve this problem, the current transformer does not have to be dismantled and installed again, but the transformer secondary (S1 and S2) just has to be inverted.
   b). The connection of the current secondary in the current transformers have been incorrectly connected; to resolve this problem just connect the S1 transformer secondary to the S1 on the meter and the S2 on the current transformer to the S2 on the meter

2. The BJ-194E, once cabled and connected, is seen to give an incoherent Power factor and Cos reading (-0.01 or similar).
   This is again a current transformer and voltage phase connection error phase A, must correspond to the current transformer installed in phase A; phase B, must correspond to the current transformer installed in phase B; and phase C, must correspond to the current transformer installed in phase C.
   This connection is clearly shown on the back of the analyzer.

3. The BJ-194E is measuring in average voltage and is displaying the secondary voltage (for example 110 volts).
   Ensure that the voltage Transformer ratio has been correctly set (see section on 7.3.4).

4. The BJ-194E does not correctly display the current reading. It shows values varying between 0 to 5 amps of current.
   Ensure that the Transformer ratio has been correctly set; once correctly set the current measurement shall be shown correctly (see section on 7.3.5).
