SAFETY CONSIDERATIONS

This device is marked with the international Caution symbol. It is important to read this
manual before installing or commissioning this device as it contains important information
relating to Safety and EMC (Electromagnetic Compatibility).

Unpacking & Inspection

Unpack the instrument and inspect for obvious shipping damage. Do not attempt to operate

Note

☞

the unit if damage is found.

This instrument is a panel mount device protected in accordance with Class I of EN 61010
(115/230 AC power connections). Installation of this instrument should be done by Qualified
personnel. In order to ensure safe operation, the following instructions should be followed.

This instrument has no power-on switch. An external switch or circuit-breaker shall be included
in the building installation as a disconnecting device. It shall be marked to indicate this function,
and it shall be in close proximity to the equipment within easy reach of the operator. The switch
or circuit-breaker shall not interrupt the Protective Conductor (Earth wire), and it shall meet the
relevant requirements of IEC 947–1 and IEC 947-3 (International Electrotechnical Commission).
The switch shall not be incorporated in the mains supply cord.

Furthermore, to provide protection against excessive energy being drawn from the mains supply in
case of a fault in the equipment, an overcurrent protection device shall be installed.

• The Protective Conductor must be connected for safety reasons. Check that the power
cable has the proper Earth wire, and it is properly connected. It is not safe to operate
this unit without the Protective Conductor Terminal connected.

• Do not exceed voltage rating on the label located on the top of the instrument

Note

☞

housing.

• Always disconnect power before changing signal and power connections.

• Do not use this instrument on a work bench without its case for safety reasons.

• Do not operate this instrument in flammable or explosive atmospheres.

• Do not expose this instrument to rain or moisture.

• Unit mounting should allow for adequate ventilation to ensure instrument does not
exceed operating temperature rating.

• Use electrical wires with adequate size to handle mechanical strain and power
requirements. Install without exposing bare wire outside the connector to minimize
electrical shock hazards.

EMC Considerations

• Whenever EMC is an issue, always use shielded cables.

• Never run signal and power wires in the same conduit.

• Use signal wire connections with twisted-pair cables.

• Install Ferrite Bead(s) on signal wires close to the
instrument if EMC problems persist.

The Digital Panel Meter/Controller consists of a main assembly, signal conditioner and interface
options (if ordered) all housed in a 1/8 DIN case.
The main assembly consists of a main board and a display board which is permanently attached to it
at a 90 degree angle.
The main board provides mounting for the power supply, circuit components, and connectors for
plugging in the signal conditioner, optional analog card, and optional controller/communications
interface card (requires removal of a bypass push-on jumper).
The display board includes the analog-to-digital converter, the LED or LCD display and the push-on
jumper for programming the decimal points. Decimal point programming may also be done from the
main board connector (J1).

17.0 17.0 SPECIFICATIONS: BSCF TRUE-RMS VOLTAGE - BSCF/G TRUE RMS CURRENT
(_2000F, _2000G) AC RMS VOLTAGE, AC RMS CURRENT

17.1 GENERAL

The basic signal conditioner board is identified as a BSCF (_2000F or _9000F) for true-RMS voltage
input. The _2000 and _9000 prefix is determined by the main assembly board used with the BSCF
option board. When the BSCF board is configured differently, it is identified as a BSCF/G (_2000G or
_9000G), used for ac RMS current input.

17.2 BSCF: TRUE-RMS VOLTAGE SIGNAL CONDITIONER

Five full-scale ranges are provided in the _2000F and _9000F series.

See TRUE-RMS VOLTAGE INPUT tables Section 20. The true-RMS -to-DC converter is a monolithic
integrated circuit which computes the true-RMS value of complex input signals containing both AC
and DC components. It converts the true-RMS values to DC outputs or inputs with a crest factor of
2:1 or less.

17.3 BSCF/G: TRUE-RMS CURRENT SIGNAL CONDITIONER

Ten current ranges are provided in this series. Special full-scale (FS) ranges for other current
transformers can be provided on special order. See TRUE-RMS CURRENT INPUT tables in Section

21.

The true-RMS -to-DC converter is a monolithic integrated circuit which computes the true-RMS
value of complex input signals containing both AC and DC components. It converts the RMS values
to DC outputs or inputs with a minimum crest factor of 2:1 at full scale input.

19.0 TESTS & DIAGNOSTICS

The signal conditioner board BSCF is designed to function with a main assembly as a minimum
configuration. There is no provision for testing a signal conditioner board alone.

Signal input requirements for your configuration are identified in the specifications for the BSCF
signal conditioner.

Operating power and connections for your configuration are identified in the Main Assembly Section
of this manual.

Note: If using Main Assembly _2000, refer to Section BQ20/BQ29.
If using Main Assembly _9000 refert to Section BQ90/BQ98

Inspect the panel meter for physical damage. If damage is apparent, resolve the damage with the
shipper or your supplier. Save all packing materials.

19.1 FUNCTIONAL ELECTRICAL TESTING

NOTE: Perform this test after your meter has been configured.

1. Short terminals 4, 5, and 6 on barrier strip (TB1).

2. Apply proper power for your configuration to terminals 1, 2 and 3 on barrier strip (TB1). Display
will read approximately zero (0000).

minimum reading on the display. The point where the digits reverse order (lower to higher) will
be the null.

3. After adjusting the null, slowly adjust the internal zero-width (R25) pot to display the proper
reading (1% of full scale).

4. Apply an input signal equal to 95% of the high end of the range selected and adjust the span pot
(S), R4, for the proper reading (95% of full scale).
