1.1 Brief Introduction

The IT6000C series Bi-directional Programmable DC Power Supply supports a variety of output capabilities to satisfy different test requirement such as high current and low voltage or high voltage and low current. Meanwhile, units of the same model can be run in parallel to deliver stronger output capacity.

In addition to the above powerful and diverse output capability, based on conventional features (such as List function, comprehensive protection and other functions), the IT6000C series Bi-directional Programmable DC Power Supply also supports a variety of unique features, such as digital I/O, data logging, energy regeneration, and the selective upgrade of system files.

More functions, technical indicators and technical innovations are described

below:

• The instrument supports bi-directional energy transmission and feeds elec-

tric energy back to the grid in a pollution-free manner, thus cutting electricity

and heat dissipation costs and meeting energy-saving and environmental protection demands;

• It supports optional system file upgrade and one-click check of such informa-

tion as system version and system configuration;

• Support List, battery test, comprehensive protection and parallel function.

Quick Reference

• During the test, the instrument can record specific data type (such as voltage

value) and save it in the USB memory device;

• The front panel can be inserted with the USB memory device to support

such functions as system file upgrade, import/export of List files and data record;

• Strong Digital I/O Function: In addition to general digital signal I/O functions,

it can also be customized by supporting the wiring through different pins to meet different special needs through different pin wirings;

• Select CC loop priority or CV loop priority. If voltage and current parameters

are to be changed frequently during test, the user can directly set related parameters through [V-set] and [I-set] on the front panel, which is very convenient;

• Built-in voltage curves comply with multiple automotive standards for quick

user recall.

• Built-in maximum power point tracking (MPPT) mechanism to provide solar

photovoltaic curve simulation.

• High visible vacuum fluorescent display (VFD)

• Support optical fiber communication, which is applicable for loop control be-

tween units under parallel mode.

• Built-in USB/CAN/LAN communication interface

• Optional GPIB/RS–232 communication interface

• Optional external analog interface, and share an interface position with RS-

232.

• Strong trigger system;

• Enable a true seamless switch between positive current and negative cur-

rent while avoiding overshoot current and overshoot voltage;

• When the Sense function is turned on, it can ensure that the DUT is safe in

case of reverse connection or open circuit of the Sense line.

2.3 Connecting the Power Cord

Precautions

To prevent electric shock and damage to the instrument, observe the following

precautions.

• Before connecting power cord, be sure to confirm that the power voltage

matches with the rated input voltage of the instrument.

• Before connecting power cord, be sure to switch off the instrument. Veri-

fy that there is no dangerous voltage on the connection terminals.

• To avoid fire or electric shock, make sure to use the power cord supplied

by ITECH.

• Be sure to connect the power cord to the AC distribution box with protec-

tive grounding. Do not use terminal board without protective grounding.

• Do not use an extended power cord without protective grounding, other-

wise the protection function will fail.

Inspection and Installation

• Be sure to perform related operations and connections to feed energy

back to grid in accordance with related regulations, and meet all necessary conditions.

• Ensure that the power cord connection terminals are either insulated or

covered by the supplied protective cover so that no accidental contact with lethal voltage can occur.

Safety agency requirements dictate that there must be a way to physically disconnect the AC mains cable from the unit. A disconnect device, either a switch or circuit breaker must be provided in the final installation. The disconnect device must be close to the equipment, be easily accessible, and be marked as the disconnect device for this equipment.

Categories of Power Cords

The standard power cord specifications for this series of 3U instruments are shown below:

The red, green and yellow wires are live wires, which are correspondingly connected to the L1, L2 and L3 terminals of power input on the rear panel of the instrument; the yellow-green wire is grounding wire, which is connected to the PE

terminal of power input on the rear panel.

AC Power Input Level

The input of this series is a three-phase AC power of 380V. (Line voltage: such as the voltage between L1 and L2).

• Voltage: 380V±10% (Three-phase four-wire)

Inspection and Installation

• Frequency: 47Hz to 63Hz

Connecting the Power Cord

• For 3U model, see the steps below to connect the power cable.

• For units already assembled into a cabinet during ex-factory, if one end of

the power cable is connected, the user needs to connect the other end of the power cable to the distribution box. The connection method is same as that for the 3U model;

• For models to be assembled in parallel by the user, see contents related to

power cable connection in Cabinet Assembly Instruction.

1. Confirm that the switch of the AC power distribution box is off.

2. Confirm that the power switch is in the OFF position and verify that there is no dangerous voltage on the connection terminals.

3. Remove the protective cover outside the AC input terminal on the rear

panel.

4. Connect one end of the power cable’s round terminal to the AC power input terminal on the instrument’s rear panel.

a. You only need to connect the red, green and yellow live wires to the ter-

minals on the rear panel, which are not required to correspond to L1, L2 and L3 terminals one by one.

b. The yellow-green wire is grounding wire, which is connected to the pro-

tective grounding terminal (PE).

Inspection and Installation

5. Mount the protective cover back to its original position.

6. Connect the other end of the power cable to the required AC distribution

box.

The schematic is shown below.

2.4 Connecting the Device Under Test (DUT)

This section describes how to connect the test cables between the instrument and DUT.

Precautions

To prevent electric shock and damage to the instrument, observe the following precautions.

Inspection and Installation

• Before connecting test cables, be sure to switch off the instrument.

Power switch is in Off position, otherwise touching the output terminals on the rear panel may result in personal injury or death due to electric shock.

• To avoid electrical shock, before testing, please make sure the rating val-

ues of the testing cables, and do not measure the current that higher than the rating value. All test cables shall be capable of withstanding the maximum short circuit current of the instrument without causing overheat.

• If several loads are provided, each pair of load wires shall safely with-

stand the rated short circuit output current of the power supply under full load.

• Do not short the battery when connecting or disconnecting the battery

testing circuit. Short circuit may cause severe accident.

• Because the instrument can be used to sink current, hazardous voltages

from an external energy source such as a battery may be present on the output terminals even with the instrument power off. Provision must be made to disconnect the external energy source before touching the output or sense terminals.

• Always use test cables provided by ITECH to connect the equipment. If

test cables from other factories are used, please confirm the maximum current that the test cables can withstand.

• During wiring, check that the positive and negative poles of the test ca-

bles are properly and tightly connected. Do not connect the positive pole and disconnect the negative pole.

• Ensure that the output terminals are either insulated or covered using

the safety covers provided, so that no accidental contact with lethal voltages can occur.

Specification for Test Cables

Test cables are not standard accessories for the instrument. Please select op-

tional red and black test cables for individual sales based on the maximum current value. For specifications of test cables and maximum current values, refer to A.1 Appendix→Specifications of Red and Black Test Lines.

Connecting the DUT (Local Measurement)

The instrument supports two kinds of wiring methods with the DUT: local measurement and remote measurement (SENSE). The default test mode is local measurement.

The connection diagram and steps of local measurement are as follows:

Inspection and Installation

1. Confirm that the power switch is in the OFF position and verify that there is no dangerous voltage on the connection terminals.

2. Remove the output terminals cover of the power supply.

3. Loosen the screws of the output terminals and connect the red and black test cables to the output terminals. Re-tighten the screws.

When maximum current that one test cable can withstand fails to meet the rated current, use multiple pieces of red and black test cables. For example, the maximum current is 1,200A, then 4 pieces of 360A red and black cables are required.

4. Thread the red and black test cables through the output terminals cover of the power supply and install the cover.

5. (Optional) According to the actual situation of DUT, connect the grounding terminal on the rear panel of the instrument to the DUT to ensure the safe grounding.

For the location information, see 1.5 Rear Panel Introduction.

6. Connect the other end of the red and black cables to the DUT. The positive and negative poles must be properly connected and fastened when wiring.

Connecting the DUT (Remote Sensing)

Remote measurement is available for the following scenarios:

When the DUT consumes large current or the wires are too long, there is a voltage drop on the wires between DUT and output terminals of the power supply.

To maximize measurement accuracy, the power supply provides the remote measurement terminals VS+ and VS- on the rear panel, which can be used to measure the terminal voltage of the DUT.

When the power supply is used for battery testing in actual applications, the voltage drop of the wire will lead to voltage inconsistency of both ends and inconsistency of the cutoff voltage of power supply and the actual voltage of bat-

tery, resulting in inaccurate measurement.

The connection diagram and steps of remote measurement are as follows:

Inspection and Installation

1. Confirm that the power switch is in the OFF position and verify that there is no dangerous voltage on the connection terminals.

2. Refer to the wiring diagram and connect the Vs+ and Vs- with armored twisted-pair cables.

To ensure the stability of the system, use armored twisted-pair cables between the remote sense terminals and the DUT. Pay attention to the positive and negative poles when wiring, otherwise it will damage the instrument.

3. Remove the output terminals cover of the power supply.

4. Loosen the screws of the output terminals and connect the red and black test cables to the output terminals. Re-tighten the screws.

5. Thread the red and black test cables through the output terminals cover of the power supply and install the cover.

6. (Optional) According to the actual situation of DUT, connect the grounding terminal on the rear panel of the instrument to the DUT to ensure the safe grounding.

For the location information, see 1.5 Rear Panel Introduction.

7. Connect the other end of the remote sense cables to the DUT.

8. Connect the other end of the red and black cables to the DUT. The positive and negative poles must be properly connected and fastened when wiring.

9. Power on the instrument and turn on the Sense function of the instrument.

For details, see 5.7 Sense Function (Sense).

Never touch cables or connections immediately after turning off the instrument at the end of the test. Lethal voltages may remain at the output terminals after turn-off. Verify that there is no dangerous voltage on the output or sense terminals before touching them.

2.5 Remote Interface Connection

This series power supply comes standard with four communication interfaces: USB, LAN and CAN, and supports two optional communication interfaces: GPIB, RS-232. You can choose one of them to communicate with your computer.

When you use the remote interface to send SCPI instructions, if you use the programming commands that involve modifying the instrument settings, such as modifying the output voltage value, after completing the communication connection between the instrument and the host computer, and after the communication settings are completed, you must execute the SYST:REM command firstly.

2.5.1 USB Interface

The USB interface is located on the rear panel of the instrument. You can connect the instrument to the computer via a cable with a USB interface on both ends (USB A-type connector on one end and USB B-type connector on the other).

Inspection and Installation

The user needs to select the USB interface type in the System menu before using the USB interface. The following three types are optional.

• TMC: USB_TMC interface;

• VCP: Virtual serial port. Select this type, you need to install the correspond-

ing driver.

Please contact ITECH Technical Support for the driver.

• LAN: USB-LAN interface, which is a virtual network port.

After selecting this option, you also need to set the communication parameters of the LAN, and the menu items are the same as those in the LAN menu.

ters of the virtual serial port, and the baud rate must be the same as the configuration on the computer side.

• If you select LAN, you also need to set the parameters related to LAN

communication.

2.5.2 LAN Interface

Connect Interface

Use the following steps to quickly connect your instrument to your LAN and configure it. Two typical LAN interface systems are described below: private LAN

and site LAN.

• Connect to the private LAN

A private LAN is a network in which LAN-enabled instruments and com-

puters are directly connected. They are typically small, with no centrallymanaged resources. When connected to a computer, a standard network cable can be used to connect directly to the computer via the LAN interface.

Inspection and Installation

• Connect to the site LAN

A site LAN is a local area network in which LAN-enabled instruments and computers are connected to the network through routers, hubs, and/or switches. They are typically large, centrally-managed networks with services such as DHCP and DNS servers. When connected to a computer, a network cable can be used to connect to the router, and the computer is also con-

nected to the router.

• When using one crossover cable to connect PC directly, the gateway address of

the instrument should be consistent with that of the PC, and the IP address

should be at the same network segment with the PC’s IP address.

• When the instrument and computer are connected to the router, an independent

IP address must be assigned for the instrument.

View LAN Interface Information

The operation steps to view the LAN interface information in the System Menu are as follows.

1. Press the composite keys [Shift]+[P-set] (System) on the front panel to enter the system menu.

2. Rotate the knob or press the Up/Down key to select I/O and press [Enter].

3. Press the Left/Right key to select LAN and press [Enter].

4. Press the Left/Right key to select Info and press [Enter].

5. Press the Up/Down key or rotate the knob to view the LAN parameters. See the information in 1.8 System Menu Function for details.

Configure LAN Interface Information

The configurable parameters of the IT6000C series power supply are described as follows.

IP-Conf

• IP Addr: This value is the Internet Protocol (IP) address of the instrument. An

IP address is required for all IP and TCP/IP communications with the instrument. An IP Address consists of 4 decimal numbers separated by periods. Each decimal number ranges from 0 through 255 with no leading zeros (for example, 169.254.2.20).

• Sub Net: This value is used to enable the instrument to determine if a client

IP address is on the same local subnet. The same numbering notation applies as for the IP Address. When a client IP address is on a different subnet, all packets must be sent to the Default Gateway.

Inspection and Installation

• Gateway: This value is the IP Address of the default gateway that allows the

instrument to communicate with systems that are not on the local subnet, as determined by the subnet mask setting. The same numbering notation applies as for the IP Address. A value of 0.0.0.0 indicates that no default gate-

way is defined.

• DNS1: This field enters the primary address of the server. Contact your LAN

administrator for server details. The same numbering notation applies as for

the IP Address. A value of 0.0.0.0 indicates that no default server is defined.

DNS is an internet service that translates domain names into IP addresses. It is also needed for the instrument to find and display its hostname assigned by the network. Normally, DHCP discovers the DNS address information; you only need to change this if DHCP is unused or not functional.

• DNS2: This field enters the secondary address of the server. Contact your

LAN administrator for server details. The same numbering notation applies as for the IP Address. A value of 0.0.0.0 indicates that no default server is defined.

• Socket Port: This value indicates the port number corresponding to the

service.

2.5.2.2 Using Telnet

The Telnet utility (as well as sockets), is another way to communicate with the instrument without using I/O libraries or drivers. In all cases, you must first establish a LAN connection from your computer to the instrument as previously described.

Inspection and Installation

In an MS-DOS Command Prompt box, type “telnet hostname” where hostname is the instrument’s hostname or IP address. Press the Enter key and you should get a Telnet session box with a title indicating that you are connected to the instrument and 23 is the instrument’s telnet port. Type the SCPI commands at the prompt.

2.5.2.3 Using Sockets

• Before using this function, you need to configure Socket Port, and the

configuration on the instrument side should be consistent with the configuration on the PC side.

• The instruments allow any combination of up to six simultaneous socket

and telnet connections to be made.

ITECH instruments have SCPI socket services, which can be used to send and receive ASCII/SCPI commands, queries, and query responses. All commands must be terminated with a newline for the message to be parsed. All query responses will also be terminated with a newline.

2.5.3 CAN Interface

The CAN interface is located on the rear panel of the instrument and is con-

nected to the computer using a CAN communication cable. In addition to the

two pins of the CAN interface, you also need to connect a ground pin, which is pin 8 of the digital I/O interface.

Precautions

Getting Started

• Before connecting power cord, be sure to confirm that the power voltage

matches with the supply voltage.

• Before connecting power cord, be sure to switch off the instrument. Veri-

fy that there is no dangerous voltage on the terminals before touching them.

• To avoid fire or electric shock, make sure to use the power cord supplied

by ITECH.

• Be sure to connect the main power socket to the power outlet with pro-

tective grounding. Do not use terminal board without protective grounding.

• Do not use an extended power cord without protective grounding, other-

wise the protection function will fail.

• Be sure to perform related operations and connections to feed energy

back to grid in accordance with related regulations, and meet all neces-

sary conditions.

• Ensure that the input electrodes are either insulated or covered using

the safety covers provided, so that no accidental contact with lethal voltages can occur.

• If you notice strange sounds, unusual odors, fire, or smoke around or

from inside the instrument, flip the POWER switch to the (O) side to turn the instrument off, or remove the power cord plug from the outlet. The

detachable power cord may be used as an emergency disconnecting device. Removing the power cord will disconnect AC input power to the unit.

3.2 Set Output Value

The voltage value, current value, power value can all be programmed. The user can set different output parameters within the range of specifications according to the need to satisfy a range of test requirement.

After selecting the operation mode, the interface displays the setting value

under the selected operation mode and the cursor blinks to prompt. The user can use the following methods to set the values.

• Directly use the number keys to set the value.

• Rotate the knob to set the data in the cursor position. Rotate the knob clock-

wise to increase the set value and anticlockwise to decrease the set value. Once the data in the cursor position increases to ten, the value will add one

to the front position automatically. and once the data in the cursor position decreases to zero, the value will minus one from the front position

automatically. This provides convenience for the user to set. The knob can works with the left or right keys. Use the left or right keys to move the cursor position.

After entering the menu interface, the knob can also be used to scroll pa-

ges to view menu items.

3.3 Use the Front Panel Menu.

The front panel provides multiple menu keys and the user can access the instrument menu by using the front panel keys, including Config menu, System menu, Protect menu and Function menu. And the user can change the related system setting in the menu. Each menu is briefly described as follows.

• The user can set the parameters related to electrical properties in the

Config menu, including the current operation mode, slope, output delay

time, internal resistance.

Getting Started

• The user can set the function related to instrument system in the System

menu, including the key beeper, Sense function, power-on state, trigger source, communication method, data logger method, digital I/O function setting, parallel function, system information and so on.

• The user can set the parameters related to instrument protection function in

the Protect menu, including OCP /OVP/OPP /UCP/UVP.

• Function menu includes output list, batterycharging test function and so on.

The user press the complex keys to enter into the menu interface. The menu is divided according to the function item and the corresponding operation is set in the lowest level menu item. For example, the key beeper is set in System→- Beep. Set the Beep item to off or on. Please refer to 1.7 Configuration Menu

When the number in front of the menu item is blinking, indicates this item is selected currently. Press [Enter] key to enter the selected menu item and press [Esc] to exit the menu.

3.4 On/Off Control

• The [On/Off] key is used to turn the output/input on or off under normal

circumstances. Even if the instrument is in control by PC or the keyboard is locked, the [On/Off] is still valid.

• The [On/Off] key light is off and turning the output off does not place the

instrument in a safe state. Hazardous voltages may be present on all output and guard terminals. Putting the equipment into an output-off state does not guarantee that the outputs are powered off if a hardware or software fault occurs. See the cautions about connecting the test lines before connecting test lines.

You can press the [On/Off] key on the front panel to control the output status of the power supply. If the [On/Off] key light is on, indicates that the output is turned on. If the [On/Off] key light is off, indicates that the output is turned off. When the output of the power supply is on, the operating status flag (CV/CC/

CW) on the VFD will be illuminated.

Getting Started

It is recommended that you turn on the [On/Off] after the power supply is

connected to the DUT. If the power supply has no output after the output is

turned on, check the voltage and current setting value, set the voltage and

current to a non-zero value, and then turn on the output.

4.4 Config Menu for Power Supply

In this chapter, the setting items under the configuration menu are described in detail.

4.4.1 Set the CC/CV Priority Mode

CV Priority

In CV priority mode, the output is controlled by a constant-voltage feedback loop, which maintains the output voltage at its programmed setting as long as the load current remains within the positive or negative current limit settings. CV priority mode is best suited for use with resistive or high impedance loads, and loads that are sensitive to voltage overshoots. Do not use CV priority mode with low-impedance sources such as batteries, power supplies, or large charged

capacitors.

Power Supply Function

In CV priority mode, the output voltage should be programmed to the desired value. A positive and negative current limit value should also be set. The current limit should always be set to a value that is greater than the actual input current requirement of the external load. The following figure shows the CV priority op-

erating locus of the output. The area in the white quadrants shows the output as a source (sourcing power). The area in the shaded quadrants shows the output as a load (sinking power).

CC Priority

The heavy solid line illustrates the locus of possible operating points as a function of output. As shown by the horizontal portion of the line, the output voltage remains regulated at its programmed setting as long as the load current remains within the positive or negative current limit setting. A CV status flag indicates

that the output voltage is being regulated and the output current is within its limit settings.

Note that when the output current reaches either the positive or negative current limit, the unit no longer operates in constant voltage mode and the output voltage is no longer held constant. Instead, the unit will now regulate the output current at its current limit setting.

As shown by the vertical portions of the shaded quadrants, the output voltage may continue to increase in the positive direction or decrease in the negative direction as current is forced into or pulled out of the unit. When the output voltage exceeds the over-voltage protection setting, the output will shut down.

In CC priority mode, the output is controlled by a bi-polar constant current feed-

back loop, which maintains the output source or sink current at its programmed setting. The output current remains at its programmed setting, provided the load

Power Supply Function

voltage remains within the voltage limit setting. CC priority mode is best suited for use with batteries, power supplies, large charged capacitors, and loads that are sensitive to current overshoots. It minimizes current overshoots during programming, turn-on, and turn-off transitions and seamlessly transitions between

positive and negative currents.

In CC priority mode, the output current should be programmed to the desired positive or negative value. A positive voltage limit range should also be set. The voltage upper limit should always be set to a value that is greater than the actual input voltage requirement of the external load. The following figure shows the CC priority operating locus of the output. The area in the white quadrants shows

the output as a source (sourcing power). The area in the shaded quadrants shows the output as a load (sinking power).

The heavy solid line illustrates the locus of possible operating points as a function of output. As shown by the vertical portion of the line, the output current remains regulated at its programmed setting as long as the output voltage remains within its limit setting. A CC (constant current) status flag indicates that the output current is being regulated and the output voltage is within its limit settings.

Note that when the output voltage reaches the upper limit, the unit no longer operates in constant current mode and the output current is no longer held constant. Instead, the unit will now regulate the output voltage at its voltage limit setting.

As shown by the horizontal portion of the shaded quadrants, when the unit is

sinking power, the output current may continue to increase in the negative direction as more current is forced into the unit. This can happen when the instrument is connected to an external device such as a battery, and its output voltage is higher than the voltage limit setting of the instrument. Once the

Level UVP limit

Protection Delay

You can specify an OCP/OVP/OPP/UCP/UVP delay to prevent momentary output settings and status changes from tripping the protection. In most cases these momentary conditions would not be considered an protection fault, and having an OCP/OVP/OPP/UCP/UVP condition disable the output when they occur would be a nuisance. Specifying an protection delay (Delay) can ignore

these momentary changes during the specified delay period. Once the delay time has expired and the protection limit condition persists, the output will shut down.

Protection Prompt

When the instrument enters the protection state, the buzzer sounds (if Beep menu item is set as default state On), the VFD status indicators Prot and Off

are lit, and [On/Off] is turned off.

Delay

Protection delay time, see Protection Delay.

When protection is generated, the VFD screen displays the following information:

• The first row shows the meter voltage and the meter current value.

• The second row shows specific protection information, such as OVP.

Clear the Protection

After the instrument triggers protection and generates a protection message, you need to troubleshoot the possible cause. When the protection is resolved,

Although [On/Off] is turned off, there may be dangerous voltage at the output electrodes. Do not touch the wiring cable or the electrode

terminals.

the VFD will still prompt the protection information. You can manually clear the protection information record through the following methods.

• Input a pulse signal to pin 1 of the rear panel P-IO to clear the protection

information.

For details, see 5.11.1 IO–1. Ps-Clear, Not-Invert.

• Press the [Esc] or [Enter] key on the front panel to manually clear the pro-

tection information.

• Connected to the host computer, the PC sends a PROTection:CLEar com-

mand to the instrument to clear the protection information.

After the protection is cleared, you need to press the [On/Off] key on the front panel or send the OUTPut ON command to the instrument to reopen [On/Off].

voltage (i.e., the Meter value) is lower than this protection limit and the warm-up time, delay time are exceeded, the power supply will enter the UVP state.

Many reasons can cause UVP, the details are as follows:

• The set protection limit Level is greater than the voltage Meter value.

• Input too low external voltage.

• The power supply outputs a low voltage due to a fault.

The operation steps to set UVP are as follows.

1. Press the composite keys [Shift]+[Recall] (Protect) on the front panel to enter the protection menu.

2. Press the up/down key or rotate the knob to select 5. UVP (Off) and press [Enter].

3. Press the left/right key or rotate the knob to select On and press [Enter] to enter the setting interface.

4. Set the warm-up time Warm-up, protection limit Level and delay time Delay in sequence, and then press [Enter] to confirm.

4.5.6 Over-Temperature Protection (OTP)

When internal temperature of instrument is higher than about 90 °C, the instrument is under temperature protection. At this time, the instrument will automatically be OFF and VFD status indicator Prot lights up and the screen prompts

OTP.

Possible Cause

To prevent damaging heat build-up and ensure specified performance, make sure there is adequate ventilation and air flow around the instrument to ensure proper cooling. Do not cover the ventilation holes on the rear panel, sides, or bottom of the instrument. Even with proper ventilation, the instrument can overheat in the following situations.

How to Set

Power Supply Function

• If the ambient temperature is too high.

• If you use the instrument to test for long periods.

The OTP limit does not need to be set, and the internal device of the instrument automatically detects and determines whether to enter the OTP state.

If an over-temperature condition occurs, power off the instrument and allow it to cool for at least 30 minutes. After the internal temperature of the instrument has cooled down, power it on again.

When you return power to the instrument, verify that the cooling fan is running. If not, please contact ITECH Technical Support. Leaving the instrument powered on with an inoperative cooling fan may result in damage to the instrument.

4.5.7 Sense Reverse Protection

The instrument defaults to provide sense reverse protection. The premise is that the Sense switch is turned on. When the output state is ON and the difference between output terminal voltage and sense remote voltage exceeds the specified voltage, sense reverse protection will be enabled after 500ms. The instru-

ment output will be immediately switched to Off and the display screen will display SENSE ERR if the sense terminals are reversed.

When the instrument is in Sense Reverse Protection state, you should check whether the polarities are connected reversely or not firstly. If yes, you can reopen the output after the polarities connect correctly.

The voltage difference between output terminal and remote sense terminal of

each model is not the same. When the remote sense terminal is connected reversely, the maximum voltage will not exceed the sum of output terminal voltage and the difference voltage.

When Sense is reversed or short-circuited, the voltage meter value is dis-

played as a positive/negative value close to 0, and abnormal high voltage

output does not occur, which can avoid damage to the DUT.

Load Dump Dynamic Behavior

This test is a simulation of load dump transient occurring in the event of a discharged battery being disconnected while the alternator is generating charging current with other loads remaining on the alternator circuit at this moment.

• The amplitude of load dump is determined by the rotational speed of alterna-

tor and the strength of magnetic field in the case of disconnection of the battery.

• The pulse duration of load dump is mainly determined by the time constant

and pulse amplitude of the excitation circuit.

Power Supply Function

Inside most novel alternator, the amplitude of load dump is decreased by increasing the limiter diode (clamping diode). The load dump may be caused by cable corrosion, poor cable contact or disconnecting the battery intentionly when the engine is running.

E-04 Jump Start

Power Supply Function

External starting of the vehicle is simulated. The maximum test voltage results from commercial vehicle systems and their increased power supply voltage. The test pulse of E-04 Jump start is shown in the figure below:

E-05 Load Dump

Dumping of an electric load, in combination with a battery with reduced buffering ability, results in an energy-rich overvoltage pulse due to the generator charac-

teristics. The test pulse of E-05 Load Dump is shown in the figure below:

E-07 Slow Decrease and Slow Increase of the Supply Voltage

The slow decrease and increase of the supply voltage is simulated as it occurs during the slow decharging and charging procedure of the vehicle battery. The waveform is as follows.

E-08 Slow Decrease and Quick Increase of the Supply Voltage

This test simulates the slow decrease of the battery voltage to 0 V and the sudden reconnection of the battery voltage e.g. by means of applying a jump start

source. The waveform is as follows.

Power Supply Function

E-09 Reset Behavior

The reset behavior of a component in its environment is simulated and tested.

Test boundary conditions (e.g. assembly, terminal, system) must be described in detail.

During operation, an arbitrary sequence of repeated switching-on/off procedures occurs; this must not lead to an undefined behavior of the component. The reset behavior is represented by a voltage variance and a time variance. Two different test sequences are required to simulate different switchoff times.

A component must always undergo both sequences.

E-11 Start Pulses

When starting the engine, the battery voltage drops to a low value for a short period and then slightly rises again. Most components are activated directly before starting for a short period, then deactivated during starting and activated again after starting when the engine is running. This test serves to verify normal oper-

ation under these conditions. The starting process may be performed under different vehicle starting conditions, cold start and warm start. In order to cover both cases, two different test sequences are required. A component must always undergo both sequences.
