1 Safety Summary

The following safety precautions apply to both operating and maintenance personnel and must be followed during all phases of operation, service, and repair of this instrument.

Before applying power to this instrument:

 Read and understand the safety and operational information in this manual.

 Apply all the listed safety precautions.

 Verify that the voltage selector at the line power cord input is set to the correct line

voltage. Operating the instrument at an incorrect line voltage will void the warranty.

 Make all connections to the instrument before applying power.

 Do not operate the instrument in ways not specified by this manual or by B&K Precision.

Failure to comply with these precautions or with warnings elsewhere in this manual violates the safety standards of design, manufacture, and intended use of the instrument. B&K Precision assumes no liability for a customer’s failure to comply with these requirements.

Category rating

The IEC 61010 standard defines safety category ratings that specify the amount of electrical energy available and the voltage impulses that may occur on electrical conductors associated with these category ratings. The category rating is a Roman numeral of I, II, III, or IV. This rating is also accompanied by a maximum voltage of the circuit to be tested, which defines the voltage impulses expected and required insulation clearances. These categories are:

Category I (CAT I): Measurement instruments whose measurement inputs are not intended to be connected to the mains supply. The voltages in the environment are typically derived from a limited-energy transformer or a battery.

Category II (CAT II): Measurement instruments whose measurement inputs are meant to be connected to the mains supply at a standard wall outlet or similar sources. Example measurement environments are portable tools and household appliances.

Category III (CAT III): Measurement instruments whose measurement inputs are meant to be connected to the mains installation of a building. Examples are measurements inside a building's circuit breaker panel or the wiring of permanently-installed motors.

Category IV (CAT IV): Measurement instruments whose measurement inputs are meant to be connected to the primary power entering a building or other outdoor wiring.

Do not use this instrument in an electrical environment with a higher category rating than what is specified in this manual for this instrument.

You must ensure that each accessory you use with this instrument has a category rating equal to or higher than the instrument's category rating to maintain the instrument's category rating. Failure to do so will lower the category rating of the measuring system.

Electrical Power

This instrument is intended to be powered from a CATEGORY II mains power environment. The mains power should be between 190 V to 250 V RMS. Use only the power cord supplied with the instrument and ensure it is appropriate for your country of use.

Ground the Instrument

To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical safety ground. This instrument is grounded through the ground conductor of the supplied, three-conductor AC line power cable. The power cable must be plugged into an approved three-conductor electrical outlet. The power jack and mating plug of the power cable meet IEC safety standards.

Do not alter or defeat the ground connection. Without the safety ground connection, all accessible conductive parts (including control knobs) may provide an electric shock. Failure to use a properly-grounded approved outlet and the recommended three-conductor AC line power cable may result in injury or death.

Unless otherwise stated, a ground connection on the instrument's rear panel is for a reference of potential only and is not to be used as a safety ground.

Do not operate in an explosive or flammable atmosphere

Do not operate the instrument in the presence of flammable gases or vapors, fumes, or finelydivided particulates.

The instrument is designed to be used in office-type indoor environments. Do not operate the instrument

 In the presence of noxious, corrosive, or flammable fumes, gases, vapors, chemicals, or

finely-divided particulates.

 In relative humidity conditions outside the instrument's specifications.

 In environments where there is a danger of any liquid being spilled on the instrument or

where any liquid can condense on the instrument.

 In air temperatures exceeding the specified operating temperatures.

 In atmospheric pressures outside the specified altitude limits or where the surrounding

gas is not air.

 In environments with restricted cooling air flow, even if the air temperatures are within

specifications.

 In direct sunlight.

This instrument is intended to be used in an indoor pollution degree 2 environment. The operating temperature range is 0 °C to 40 °C and 20% to 80% relative humidity, with no condensation allowed.

Measurements made by this instrument may be outside specifications if the instrument is used in non-office-type environments. Such environments may include rapid temperature or humidity changes, sunlight, vibration and/or mechanical shocks, acoustic noise, electrical noise, strong electric fields, or strong magnetic fields.

Do not operate instrument if damaged

If the instrument is damaged, appears to be damaged, or if any liquid, chemical, or other material gets on or inside the instrument, remove the instrument's power cord, remove the instrument from service, label it as not to be operated, and return the instrument to B&K Precision for repair. Notify B&K Precision of the nature of any contamination of the instrument.

Not for critical applications

This instrument is not authorized for use in contact with the human body or for use as a component in a life-support device or system.

Do not touch live circuits

Instrument covers must not be removed by operating personnel. Component replacement and internal adjustments must be made by qualified service-trained maintenance personnel who are aware of the hazards involved when the instrument's covers and shields are removed. Under certain conditions, even with the power cord removed, dangerous voltages may exist when the covers are removed. To avoid injuries, always disconnect the power cord from the instrument, disconnect all other connections (for example, test leads, computer interface cables, etc.), discharge all circuits, and verify there are no hazardous voltages present on any conductors by measurements with a properly-operating voltage-sensing device before touching any internal parts. Verify the voltage-sensing device is working properly before and after making the measurements by testing with known-operating voltage sources and test for both DC and AC voltages. Do not attempt any service or adjustment unless another person capable of rendering first aid and resuscitation is present.

Do not insert any object into an instrument's ventilation openings or other openings.

Hazardous voltages may be present in unexpected locations in circuitry being tested when a fault condition in the circuit exists.

Fuse replacement

Fuse replacement must be done by qualified service-trained maintenance personnel who are aware of the instrument's fuse requirements and safe replacement procedures. Disconnect the instrument from the power line before replacing fuses. Replace fuses only with new fuses of the fuse types, voltage ratings, and current ratings specified in this manual or on the back of the instrument. Failure to do so may damage the instrument, lead to a safety hazard, or cause a fire. Failure to use the specified fuses will void the warranty.

Servicing

Do not substitute parts that are not approved by B&K Precision or modify this instrument. Return the instrument to B&K Precision for service and repair to ensure that safety and performance features are maintained.

For continued safe use of the instrument

 Do not place heavy objects on the instrument.

 Do not obstruct cooling air flow to the instrument.

 Do not place a hot soldering iron on the instrument.

 Do not pull the instrument with the power cord, connected probe, or connected test

lead.

Connection of the 9832 or 9833 to an AC power source should be made by a qualified electrician or other qualified personnel. Incorrect wiring may damage the source or cause a fire hazard.

The included AC power cord is safety certified for this instrument operating in the rated range. If an extension cable is added, be sure that it can meet the required power ratings for this instrument. Any misuse with wrong or unsafe cables will void the warranty.

5 Getting Started

Before connecting and powering up the instrument, please review and go through the instructions in this chapter.

5.1 Input Power Requirements

The AC input accepts line voltage input within:

Voltage: 190 V – 250 V

Frequency: 47 Hz – 63 Hz

Maximum power consumption: 9832: 2500VA; 9833: 38000 VA

Before connecting to an AC outlet or external power source, make sure that the power switch is in the OFF position and verify that the AC power cord, including the extension line, is compatible with the rated voltage/current and that there is sufficient circuit capacity for the power supply.

Follow the illustrations below to connect the new AC power cord to the AC input of the source in the rear panel.

5.1.1 North American Split Phase Power

Split phase is commonly used in North American to provide 208 to 240 Volts. This requires two wires that are both hot. For example 110 V and, 110 V resulting in 220 V across them. The included cable may be used in most regions by adding a band of blue electrical tape on each end of the white wire to identify both the black and white with blue band as hot. The green trace yellow wire is always used for ground and must be connected properly. Check with your local Authority Having Jurisdiction for clarification.

The power cable that is shipped with the instrument is preassembled from the factory. The following instruction will provide information for changing the power cable for split phase.

1. Verify that the source power in your facility can provide the minimum voltage and

current required to operate the instrument.

2. Using the power cable provided, identify the end that plugs into the instrument.

Before disassembling the black hooded connector, make a note of how the unit is assembled from the factory so it can be correctly reassembled.

3. Remove the 4 screws from the bottom of the hooded connector as shown and place the upper and the upper and lower hood pieces and screws to the side.

The black, white, and green wires should now be clearly visible. Use a screwdriver to unscrew and release the white wire only.

Add a band of blue electrical tape or heat shrink to each end of the white wire.

1. Return the white wire into the green connecter and tighten the screw. Verify all

three wires are secured in the connector.

2. Closely inspect each of the wires at the enter point of the green connector to

verify none of the copper strands are bridging over to the wrong terminal causing a short.

3. Carefully reassemble the hood so the Latch Fingers and Caution Label are facing

up and reinstall the 4 screws into the hood. The green connector should be

Any disassembling of the case or fuse changes not performed by an authorized service technician will void the warranty of the instrument.

locked in place.

4. Using the (2) screws provided with the cable, secure the assembled connector to

the back of the instrument as shown in Figure 10 – Securing. Note: Use only the screws provided.

The green (trace yellow) wire connects to electrical ground (required). The black wire connects to L (Line 1) and the white with blue band connects to N (Line 2).

5.1.2 Fuse

The factory installed fuse will meet the requirements when the instrument is operated with the specified Input Power requirements. This source is a switching mode power supply. The fuse installed inside should not fail under normal operation. If the fuse has blown, it may be an indication of a more serious malfunction inside of the source. In this event, contact B&K Precision.

5.2 Preliminary Check

5.2.1 Power-on Procedure

1. Complete the following steps to verify that the source is ready for use.

2. Verify AC Input Voltage

Figure 10 - Securing the power cable

3. Verify and check to make sure proper AC voltages are available to power the

instrument. The AC voltage range must meet per the acceptable specifications.

Do not connect multiple power supplies in series or parallel as this may cause damage or a malfunction.

When the AC input voltage is lower than 190 VAC, the source will activate an inner over temperature protector and cut off the output in response to the condition. To ensure that the entire test process can be completed smoothly, confirm that the input AC voltage is within the specified range.

When the AC input frequency is outside the range of 47 to 63 Hz, the source will beep. To ensure the normal operation of the source, please make sure the AC input frequency is within the required range.

4. Connect Power

5. Connect specified AC power cord and verify the hood is in place and correctly secured to rear panel.

6. Press the power switch to the “|” ON position to turn ON the instrument. It will take a few seconds before the fans power on and the self-test begins.

5.2.2 Warm-up Time

The 9830 series is fully operable upon switching the power on. However, to reach the specified equipment accuracy, please allow the source to warm up for at least 15 minutes.

5.2.3 Power-off Procedure

When the instrument is not in use, make sure to set the front panel power switch to the OFF position. After the power switch is turned off the internal fans will continue to run for approximately 5-10 seconds to discharge the internal capacitors per safety requirements. Once the discharge process is complete, the instrument will carry out an automatic shutdown process of approximately 2-8 seconds. Do not turn the power back on until the instrument has completed a full shut down cycle.

5.3 Sense Lines

The source can be configured as local sense or remote sense to compensate the voltage drop of the test leads. The following diagram shows how to connect the load by local sense or remote sense configurations.

When local sense is selected, the sense end L is connected to the output end L and sense end N is connected to the output end N, whereas the output end L is connected to the load end L and output end N is connected to the load end N. When this sensing mode is selected, the wires connecting between the sense ends to the load end must be as short as possible. The local sense is the default configuration. When remote sense is selected, both

The USB interface does not support flow control. The programmer should be aware of this limitation and pay attention to the Instrument command process time. If the remote commands are sent too fast the internal buffer may overrun and cause communication errors. Therefore, it is mandatory to add a delay between commands so that the Instrument can have sufficient time to process.

The Instrument comes with RS232, USB (USBTMC, and USBVCP), GPIB, LAN and analog interfaces. Users can program the Instrument using the SCPI (Standard Commands for Programmable Instruments) commands through any of the remote interfaces. Only one interface at a time can be enabled and used to control the Instrument.

11.1 Interface Connection

11.1.1 RS232

The RS232 interface can be found on pin 23 (RX) and 11 (TX) of the DB25 port. See the settings below:

Table 17 - RS232 Settings

11.1.2 USBVCP (virtual COM)

The USB port is a virtual COM port, which can be used for remote communication. See the settings below:

USBVCP Driver The USBVCP driver for the SiLabs CP210x used in the unit can be downloaded from the

following link. https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

11.1.3 USBTMC

The USB port is USBTMC-compliant and can be used for remote communication and control. There are no additional settings in the menu system for USB configuration. The only requirement is that the USBTMC driver be installed. It is included when installing VISA software on the computer. (We recommend using NI-VISA, which can be downloaded at http://www.ni.com/visa/).

11.1.4 GPIB

Each device is assigned a GPIB address from 1-30. To communicate via GPIB, connect a GPIB cable to the GPIB interface on the back of the instrument and configure the address.

11.1.5 LAN (Ethernet)

There are three ways to control the Instrument via LAN interface: Web server, Telnet connection, and Socket connection.

11.1.6 Web server

There is an embedded web server GUI (Graphical User Interface) that can access the Instrument via LAN interface using a web browser. Using a web browser from a computer connected to the same local area network as the Instrument. The GUI provides a simple way to set the voltage and current, and to monitor the output. To use this function, follow the steps below:

Open up a web browser on the computer.

1. Check the IP address of the Instrument through menu tree System → Information.

2. Enter the IP address of the Instrument in the URL bar of your browser with IP

When the output sine wave of the Instrument is about to pass through 0 degrees, pin 9 (/SYNC) will send out a 250 uS 12 V to 0 V pulse as shown in the below timing diagram. This output

Figure 52 - Sync Timing Diagram

12.4.2 /Fault_out

Pin 16 (/Fault_out) indicates when a fault occurs or the Instrument is in protection status. During normal operation, the voltage level of this pin stays high (5 V). The voltage level will be low (0 V) if any of the circumstances below occurs:

4. Interface CAN Error

5. Module CAN Error

6. SW Over Current Prot

7. SW Over Voltage Prot

8. SW Over Power Limit

9. SW Over Max VA Limit

10. Remote Inhibit ON

12.4.3 /Transient

When the output status changes, pin 21 (/Transient ) will send out a 500 uS, 5 V to 0 V pulse to synchronize with another external device as shown in the below timing

diagram. This function is not available in the Program modes. To active this function, follow the settings: Configure → Config 2 → Transient → ON.

Figure 53 - Transient Timing Diagram

12.5 Remote_Inhibit

The Instrument offers a remote inhibit used to turn the output off. The voltage level of pin 19 (Remote_inhibit) (reference ground is DGND) has to be set high (5 V) first, or the Instrument will enter into protection mode. If the voltage level drops to 0 V, the Instrument will stop outputting, and will show ‘Error Remote Inhibit ON’.

Follow the settings: Configure → Config 2 → Remote_Inhibit → ON

The RS232 interface does not support flow control. The programmer should be aware of this limitation and pay attention to the Instrument command process time. If the remote commands are sent too fast the internal buffer may overrun and cause communication errors. Therefore, it is mandatory to add a delay between commands so that the Instrument has sufficient time to process.
