1.4.2. Test Station

Location

Select an area away from the main stream of activity which employees do not walk through in performing their normal duties. If this is not practical because of production line flow, then the area should be roped off and marked for TESTING. No employees other than the test operators should be allowed inside.

If benches are placed back-to-back, be especially careful about the use of the bench opposite the test station. Signs should be posted: "DANGER - TEST IN PROGRESS -

UNAUTHORIZED PERSONNEL KEEP AWAY."

Work Area

Perform the tests on a non-conducting table or workbench, if possible.

There should not be any metal in the work area between the operator and the location where products being tested will be positioned.

Position the tester so the operator does not have to reach over the product under test to activate or adjust the tester. If the product or component being tested is small, it may be possible to construct guards or an enclosure around the device to be tested. Construct the guards of a nonconducting material such as clear acrylic, so that the item being tested is within the guards or enclosure during the test. If possible, the guards or enclosure should also contain safety switches that will not allow the tester to operate unless the guards are in place or the enclosure closed.

Keep the area clean and uncluttered. All test equipment and test leads not necessary for the test should be removed from the test bench and put away. It should be apparent to both the operator and to any observers, the product that is being tested and the product that is waiting to be tested, or has already been tested.

Do not perform Ground Bond tests in a combustible atmosphere or in any area where combustible materials are present.

Power

Be certain that the power wiring to the test bench is properly polarized and that the proper low resistance bonding to ground is in place.

Power to the test station should be arranged so that it can be shut off by one prominently marked switch located at the entrance to the test area. In case of an emergency, anyone can cut off the power before entering the test area to offer assistance.

5

1.4.3. Test Operator

Qualifications

The operator should understand the electrical fundamentals of voltage, current, and resistance.

Rules

Operators should be thoroughly trained to follow all of the aforementioned rules, in addition to any other applicable safety rules and procedures. Defeating any safety system should be considered a serious offense with severe penalties such as removal from the Ground Bond testing job. Allowing unauthorized personnel in the area during a test should also be dealt with as a serious offense.

Dress

Operators should not wear jewelry that could accidentally complete a circuit.

Medical Restrictions

Personnel with heart ailments or devices such as pacemakers should be informed that the current generated by the instrument are very dangerous. If contacted it may cause heart-related problems that a person of good health may not experience. Please have the test operator consult their physician for recommendations.

1.5. Introduction to Product Safety Testing

1.5.1. The Importance of Safety Testing

Product Safety Tests are specified during the design and development stages of a product as well as in the production of the products to insure that it meets basic safety requirements.

These tests are designed to verify the safety of the electrical products in that they do not jeopardize the safety of the people, domestic animals, and property of anyone who may come in contact with these products. In an era of soaring liability costs, original manufacturers of electrical and electronic products must make sure every item is as safe as possible. All products must be designed and built to prevent electric shock, even when users abuse the equipment or by-pass built in safety features.

To meet recognized safety standards, one common test is the "dielectric voltage-withstand test". Safety agencies which require compliance safety testing at both the initial product design stage and for routine production line testing include: Underwriters Laboratories, Inc. (UL), the

Canadian Standards Association (CSA), the International Electrotechnical Commission (IEC), the British Standards Institution (BSI), the Association of German Electrical Engineers (VDE) and (TÜV), the Japanese Standards Association (JSI). These same agencies may also require that an insulation resistance test and high current ground bond test be performed.

1.6. The Different Types of Safety Tests

1.6.1. Dielectric Withstand Test

The principle behind a dielectric voltage - withstand test is simple. If a product will function when exposed to extremely adverse conditions, it can be assumed that the product will function in normal operating circumstances.

Common Applications of the Dielectric Withstand Test:

• Design (performance) testing: Determining design adequacy to meet service conditions.

• Production Line testing: Detecting defects in material or workmanship during processing.

• Acceptance testing: Proving minimum insulation requirements of purchased parts.

• Repair Service testing: Determine reliability and safety of equipment repairs.

The specific technique used to apply the dielectric voltage - withstand test to each product is different. During a dielectric voltage - withstand test, an electrical device is exposed to a voltage significantly higher than it normally encounters, for a specified duration of time.

During the test, all current flow from the high voltage output to the return is measured. If, during the time the component is tested, the current flow remains within specified limits, the device is assumed safe under normal conditions. The basic product design and use of the insulating material will protect the user against electrical shock.

7

The equipment used for this test, a dielectric-withstand tester, is often called a "hipot" (for high potential tester). The "rule of thumb" for testing is to subject the product to twice its normal operating voltage, plus 1,000 volts.

However, specific products may be tested at much higher voltages than 2X operating voltages

+ 1,000 volts. For example, a product designed to operate in the range between 100 to 240 volts can be tested between 1,000 to 4,000 volts or higher. Most "double insulated" products are tested at voltages much higher than the "rule of thumb".

Testing during development and prototype stages is more stringent than production run tests because the basic design of the product is being evaluated. Design tests usually are performed on only a few samples of the product. Production tests are performed on every item as it comes off the production line.

The hipot tester must also maintain an output voltage between 100% and 120% of specification. The output voltage of the hipot must have a sinusoidal waveform with a frequency between 40 to 70 Hz and has a peak waveform value that is not less than 1.3 and not more than 1.5 times the root-mean-square value.

Types of Failures only detectable with a Hipot test

• Weak Insulating Materials

• Pinholes in Insulation

• Inadequate Spacing of Components

• Pinched Insulation

Dielectric Withstand Test; AC verses DC

Please check with the Compliance Agency you are working with to see which of the two types of voltages you are authorized to use. In some cases, a Compliance Agency will allow either

AC or DC testing to be done. However, in other cases the Compliance Agency only allows for an AC test. If you are unsure which specification you must comply with please contact our

CUSTOMER SUPPORT GROUP at 1-800-858-TEST (8378).

Many safety agency specifications allow either AC or DC voltages to be used during the hipot test. When this is the case, the manufacturer must make the decision on which type of voltage to utilize. In order to do this it is important to understand the advantages and the disadvantages of both AC and DC testing.

AC testing characteristics

Most items that are hipot tested have some amount of distributed capacitance. An AC voltage cannot charge this capacitance so it continually reads the reactive current that flows when AC is applied to a capacitive load.

8

AC testing advantages

AC testing is generally much more accepted by safety agencies than DC testing. The main reason for this is that most items being hipot tested will operate on AC voltages. AC hipot testing offers the advantage of stressing the insulation alternately in both polarities, which more closely simulates stresses the product will see in real use.

Since AC testing cannot charge a capacitive load the current reading remains consistent from initial application of the voltage to the end of the test. Therefore, there is no need to gradually bring up the voltage since there is no stabilization required to monitor the current reading.

This means that unless the product is sensitive to a sudden application of voltage the operator can immediately apply full voltage and read current without any wait time.

Another advantage of AC testing is that since AC voltage cannot charge a load there is no need to discharge the item under test after the test.

AC testing disadvantages

One disadvantage of AC testing surfaces when testing capacitive products. Again, since AC cannot charge the item under test, reactive current is constantly flowing. In many cases, the reactive component of the current can be much greater than the real component due to actual leakage. This can make it very difficult to detect products that have excessively high leakage current.

Another disadvantage of AC testing is that the hipot has to have the capability of supplying reactive and leakage current continuously. This may require a current output that is actually much higher than is really required to monitor leakage current and in most cases is usually much higher than would be needed with DC testing. This can present increased safety risks as operators are exposed to higher currents.

DC testing characteristics

During DC hipot testing the item under test is charged. The same test item capacitance that causes reactive current in AC testing results in initial charging current which exponentially drops to zero in DC testing.

DC testing advantages

Once the item under test is fully charged, the only current flowing is true leakage current. This allows a DC hipot tester to clearly display only the true leakage of the product under test.

Another advantage to DC testing is that the charging current only needs to be applied momentarily. This means that the output power requirements of the DC hipot tester can typically be much less than what would be required in an AC tester to test the same product.

DC testing disadvantages

Unless the item being tested has virtually no capacitance, it is necessary to raise the voltage gradually from zero to the full test voltage. The more capacitive the item the more slowly the voltage must be raised. This is important since most DC hipots have failure shut off circuitry

9

which will indicate failure almost immediately if the total current reaches the leakage threshold during the initial charging of the product under test.

Since a DC hipot does charge the item under test, it becomes necessary to discharge the item after the test.

DC testing unlike AC testing only charges the insulation in one polarity. This becomes a concern when testing products that will actually be used at AC voltages. This is an important reason that some safety agencies do not accept DC testing as an alternative to AC.

When performing AC hipot tests the product under test is actually tested with peak voltages that the hipot meter does not display. This is not the case with DC testing since a sinewave is not generated when testing with direct current. In order to compensate for this most safety agencies require that the equivalent DC test be performed at higher voltages than the AC test.

The multiplying factor is somewhat inconsistent between agencies which can cause confusion concerning exactly what equivalent DC test voltage is appropriate.

1.6.2. Insulation Resistance Test

Some "dielectric analyzers today come with a built in insulation resistance tester. Typically, the IR function provides test voltages from 500 to 1,000 volts DC and resistance ranges from kilohms to gigaohms. This function allows manufacturers to comply with special compliance regulations. BABT, TÜV and VDE are agencies that may under certain conditions, require an

IR test on the product before a Hipot test is performed. This typically is not a production line test but a performance design test.

The insulation resistance test is very similar to the hipot test. Instead of the go/no go indication that you get with a hipot test the IR test gives you an insulation value usually in Megohms.

Typically, the higher the insulation resistance value the better the condition of the insulation.

The connections to perform the IR test are the same as the hipot test. The measured value represents the equivalent resistance of all the insulation which exists between the two points and any component resistance which might also be connected between the two points.

Although the IR test can be a predictor of insulation condition it does not replace the need to perform a dielectric withstand test.

1.6.3. Ground Bond Test

The Ground Bonding test determines whether the safety ground circuit of the product under test can adequately handle fault current if the product should ever become defective. A low impedance ground system is critical in ensuring that in case of a product failure, a circuit breaker on the input line will act quickly to protect the user from any serious electrical shock.

International compliance agencies such as CSA, IEC, TÜV, VDE, BABT and others, have requirements calling out this test. This test should not be confused with low current continuity tests that are also commonly called out in some safety agency specifications. A low current test merely indicates that there is a safety ground connection. It does not completely test the integrity of that connection.

10

Compliance agency requirements vary on how different products are to be tested. Most specifications call for test currents of between 10 and 30 amps. Test voltages at these currents are typically required to be less than 12 volts. Maximum allowable resistance readings of the safety ground circuit are normally between 100 and 200 milliohms.

If you are testing a product that is terminated in a three-prong plug, you are required to perform a continuity or ground bond test on the ground conductor to the chassis or dead metal of the product.

1.6.4. Run Test

All manufacturers of a product that runs on line power normally need to run the DUT (Device

Under Test) after final safety testing so that they can verify the functionality of their products.

In addition to running the DUT to test its basic functionality many customers also require some basic test data to be recorded while the DUT is powered up. A Run Test System allows the product to be powered up immediately after the safety tests are completed with a single connection to the DUT. Measurements that are commonly made while the DUT is running can include Amperage, Voltage, Watts and Power Factor.

1.6.5. Line Leakage Test

The Line Leakage test is one of many product safety tests that are normally specified for electrical products by safety testing agencies such as Underwriters Laboratories (UL) and the

International Electrotechnical Committee (IEC). The line leakage specifications vary as well as the method in which the measurements are taken depending upon the application or function of a product and the standard to which the product is being tested.

Current Leakage or Line Leakage tests are general terms that actually describe three different types of tests. These tests are Earth Leakage Current, Enclosure Leakage Current, and Applied

Part Leakage Current. The main differences in these tests are in the placement of the probe for the measuring device. The Earth Leakage Current is the leakage current that flows through the ground conductor in the line cord back to earth. The Enclosure Leakage Current is the current that flows from any enclosure part through a person back to ground if it were contacted by a person. The Applied Part Leakage Current or Patient Lead Leakage Current is any leakage that flows from an applied part, between applied parts or into an applied part. The Applied Part

Leakage Current test is required only for medical equipment. All of these tests are used to determine if products can be safely operated or handled without posing a shock hazard to the user.

Line Leakage Testers provide the capability of meeting the line leakage test specified in the following standards; UL 544, IEC 950, UL 1950, IEC 601-1, UL 2601, UL 1563, UL 3101,

IEC 1010 and others. The Line Leakage test, is a test which measures the leakage current of a product, through a circuit that is designed to simulate the impedance of the human body. The simulation circuit is called the Measuring Device (MD). The instrument has five different MD circuits, selectable through the menu, which are representative circuits designed to simulate the impedance of the human body under different conditions. The impedance of the human body will vary depending upon point of contact, the surface area of the contact and the path the current flows. For these reasons, the specifications of the Measuring Devices are different depending upon the type of test being performed as well as the maximum allowable leakage

11

current. Leakage current measurements are performed on products under normal conditions and single fault conditions as well as reversed polarity. This simulates possible problems, which could occur if the product under test is faulted or misused while the product is operating under high line conditions (110% of the highest input voltage rating of the product).

Line Leakage tests are normally specified as “Type Tests” or “Design Tests” which are performed during the development of the product. This helps verify that the design is safe but it does not guarantee the safety of the products being produced on the production line. The only way to be sure you are shipping safe products is to test each product at the end of the production line. The user may perform a Leakage Current test along with other common safety test such as Dielectric Withstand, Insulation Resistance, and Ground Bond on the production line with a single connection to the device under test.

Key Features and Benefits: HYAMP III

The first manual Ground Bond instrument with an enhanced graphic LCD

This provides the operator with complete test setup and results in an easy-to-use interface. This eliminates the need to decipher cryptic abbreviations. The graphic display makes testing safer, easier and more reliable than ever before.

All parameters for the setups can be adjusted through a simple menu driven program by using front panel keys

Tamper proof front panel controls

Storage of up to 10 different test programs

The easy to follow setup screens ensure that the operator correctly sets up all test parameters.

This makes it possible to limit user access to the setup screens so that only authorized personnel with a security code can change test parameters.

A real benefit for manufacturers that test different products. This makes it possible to store all the various test parameters required and quickly recall them for each of the different products that needs to be tested.

Memories can also be linked to run multi step tests.

Interconnection with HYPOT

III

Line and Load regulation

User selectable output voltage frequencies of 50 or 60 Hertz

Adjustable output current and milliohm trip ranges

Four wire measurement (Kelvin method) and milliohm offset capability

Interconnection of the HYAMP III and the HYPOT III makes these two instruments a complete test system.

The test system can be configured to test Ground Bond first and then advance to the Dielectric Withstand test and Insulation Resistance tests. The test system can also be configured to perform Ground Bond and

Dielectric Withstand tests simultaneously.

This system maintains the output current to within 2% from no load to full load and over the line voltage range to ensure that test results remain consistent and within safety agency requirements.

HYAMP III was designed for the global market. This feature makes it simple for the user to select the output frequency in the Ground Bond mode so that products can be tested at the same frequency they will be used at.

This capability makes the HYAMP III versatile enough to meet all safety agency specifications for ground bond test requirements.

These features minimize the effect of test lead resistance. The four wire measurement technique eliminates test lead resistance when using the standard test leads. The milliohm offset function allows the use of longer test leads and test fixtures without compromising the test results.

13

PLC remote inputs and outputs

The standard 9 pin interfaces provide outputs for Pass,

Fail, Test in Process, Start Out, and Reset Out. Inputs include Test, Reset, Interlock, and Withstand

Processing.

Remote recall of memory program #1, #2 and

The HYAMP III comes with all of the memories and steps loaded with the default parameters.

The initial test loaded for use is Memory 1, Step 1. If this test is unacceptable for your DUT then refer to the section 4.3 Setting Up a Test, for instructions on how to program tests into the instrument.

If these parameters are acceptable then connect an appropriate set of test leads to the device under test (DUT) or test fixture. Make sure the safety ground of this instrument is connected to a known good ground.

WARNING

DO NOT TOUCH THE DEVICE UNDER TEST ONCE THE TEST HAS

BEEN STARTED.

Remote Interlock

HYAMP III is equipped with a featured referred to as “Remote Interlock”. Remote Interlock is a feature that utilizes a set of closed contacts to enable the instruments output. In other words, if the Interlock contacts open, the output of the instrument will be disabled. Remote Interlock could also be referred to as a remote system lockout, utilizing “Fail When Open” logic. If the

Interlock contacts are open and the Test button is pushed, a pop-up message will be displayed on the screen for two seconds. The message will appear as follows:

Interlock is Open

If the Interlock contacts are opened during a test, the pop-up message will be displayed and the test will abort. The hardware has been configured to provide the interlock connections on pins

4 and 5 of the Remote Interface, Signal Input port. The instrument can still be used without the external interlock device as long as the Interlock Connector (38075 provided with unit) is plugged into the Remote Interface, Signal Input port. If there is nothing connected to the

Remote Interface, Signal Input port to provide a connection to the interlock, the instrument will not perform tests.

Please check your connections to be sure they are making good contact. Clear the area of any debris that may create a hazardous situation and ask any unnecessary personnel to leave the area. To initiate the test, press the GREEN test button on the front panel. This is a momentary button and does not need to be held in the pressed position during the test. The instrument will then initiate the test presently loaded (in this case Memory 1, Step 1) .

If the DUT passes the test, you will hear a short audible beep. If a failure occurs you will hear a long audible alarm and the red failure indicator will light up. If a failure occurs during the test, a continuous alarm will sound and the red indicator light in the Reset button will illuminate.

To stop the alarm you must press the illuminated RED button marked “RESET.” This will silence the alarm, clear the red fail light, and reset the instrument for the next test. The RESET button may also be used to quickly ABORT a test and cut off the power to the DUT.

23

When a test is being performed, a red test indicator located in the lower right side of the front panel will illuminate and flash until the test is finished. If the DUT passed the test, you will hear a brief beep indicating the DUT passed and that the tests are complete.

7. Connection of Remote I/O

Two 9-pin “D” type connectors are mounted on the rear panel that provide REMOTE-

INPUT-OUTPUT control and information. These connectors mate with standard 9 pin

D-sub-miniature connector provided by the user. The output mates to a male (plug) connector while the input mates to a female (receptacle) connector. For best performance, a shielded cable should be used. To avoid ground loops the shield should not be grounded at both ends of the cable. Suggested AMP part numbers for interconnecting to the Remote I/O are shown below:

7.1. Signal Outputs on Remote I/O

The rear panel connector provides three output signals to remotely monitor PASS, FAIL, and PROCESSING conditions, and it also provides a RESET OUT pulse signal and a

START OUT pulse signal. The monitoring signals are provided by three normally open internal relays that switch on to indicate the current condition of the tester. The RESET

OUT signal and the START OUT pulse signal are also provided by a normally open internal relay. The RESET OUT gives a signal whenever the reset function is activated.

This can be used to abort a withstand test while the units are interfaced as a test system.

The START OUT gives a momentary output pulse that can be used to start the hipot test.

These are normally open free contacts and will not provide any voltage or current. The ratings of the contacts are 1 AAC / 125 VAC (0.5 ADC / 30 VDC). The signal outputs

44

are provided on the 9 pin female type D connector. Below is a listing that indicates what conditions activate each pin. When a terminal becomes active the relay closes thereby allowing the external voltage to operate an external device.

Pins 1 and 2 provide the PASS signal.

Pins 3 and 4 provide the FAIL signal.

Pins 5 and 6 provide the PROCESSING signal.

Pins 7 and 8 provide the RESET OUT signal.

Pins 7 and 9 provide the START OUT pulse signal.

The following describes how the relays operate for each test condition.

PROCESSING - The relay contact closes the connection between pin (5) and pin (6) while the instrument is performing a test. The connection is opened at the end of the test.

PASS - The relay contact closes the connection between pin (1) and pin (2) after detecting that the item under test passed all tests. The connection is opened when the next test is initiated or the reset function is activated.

FAIL - The relay contact closes the connection between pin (3) and pin (4) after detecting that the item under test failed any test. The connection is opened when the next test is initiated or the reset function activated.

RESET OUT - The relay contact closes the connection between pin (7) and pin (8) while the reset function is activated. This is only a continuous closure dependent on the length of time the reset button is held in an active state.

START OUT - The relay contact closes the connection between pin (7) and pin (9). The

Hipot Start parameter directly controls the Start output relay. G

→W will momentarily close the start output relay at the end of the HYAMP III test and G + W will momentarily close the start output relay at the start of the HYAMP III test.

The Hipot Start parameters main purpose is to control the sequential timing between

HYAMP III and a connected Associated Research Hypot. The parameter controls if the

Hypot will run after the HYAMP III has completed its test, G

→W, or if the Hypot will run at the same time as the HYAMP III, G + W.

45

7.2. Signal Inputs of Remote I/O and Memory Access

The HYAMP III remote connector enables remote operation of the TEST, RESET,

REMOTE INTERLOCK, and WITHSTAND PROCESSING functions, and allows the operator to remotely select Memory 1, Memory 2, or Memory 3.

When the PLC Remote mode is on, the HYAMP III will respond to simple switch or relay contacts closures. A normally open momentary switch can be wired across pins 3 and 5 to allow remote operation of the TEST function. A normally open momentary switch can be wired across pins 2 and 5 to allow remote operation of the RESET function. When the PLC remote function is (ON) the TEST switch on the front panel will be disabled to prevent a test from being activated through this switch. For safety, the front panel RESET switch remains active even when a remote reset switch is connected so that high voltage can be shut down from either location.

The HYAMP III also allow access to three MEMORY PROGRAMS through the remote control connector. This gives the user the capability to quickly change parameters and initiate a test remotely. The HYAMP III basically operates in a PLC mode by responding to simple switch or relay contact closures. The built in memory programs of the instrument are used to accomplish this. Three internal memory programs can be accessed, by connecting terminals 7, 8, and 9 in different combinations.

MEMORY ONE - Momentarily connecting terminal 7 to 8 signals the instrument to immediately begin the test program that is stored in memory one.

MEMORY TWO - Momentarily connecting terminal 7 to 9 signals the instrument to immediately begin the test program that is stored in memory two.

MEMORY THREE - Momentarily connecting terminal 7 to terminals 8 and 9 signals the instrument to immediately begin the test program that is stored in memory three.

Remote Interlock

HYAMP III is equipped with a featured referred to as “Remote Interlock”. Remote

Interlock is a feature that utilizes a set of closed contacts to enable the instruments output.

In other words, if the Interlock contacts open, the output of the instrument will be disabled. Remote Interlock could also be referred to as a remote system lockout, utilizing

“Fail When Open” logic. If the Interlock contacts are open and the Test button is pushed,

46

a pop-up message will be displayed on the screen for two seconds. The message will appear as follows:

Interlock is Open

If the Interlock contacts are opened during a test, the pop-up message will be displayed and the test will abort. The hardware and has been configured to provide the interlock connections on pins 4 and 5 of the Remote Interface, Signal Input port. The instrument can still be used without the external interlock device as long as the Interlock Connector

(38075 provided with unit) is plugged into the Remote Interface, Signal Input port. If there is nothing connected to the Remote Interface, Signal Input port to provide a connection to the interlock, the instrument will not perform tests.

Withstand Processing

When a HYAMP III is integrated with a Hipot as a test system, the processing signal from the hipot tester will be sent across pin (6) and pin (7) of the HYAMP III remote input. This signal will activate the front panel “Withstand Processing” indicator that notifies the operator that high voltage is enabled.

If the Hipot start is set to G

→W (sequential) then the “Withstand Processing” indicator will appear as the following pop-up message:

W i t h s t a n d T e s t i s p r o c e s s i n g

If the Hipot start signal is set to G+W then a small W-T indicator will appear in the upper right of the display.

PLC Remote Pop-up message

If you attempt to start a test from the front panel Test button and the PLC remote function is turned “ON”, a pop-up message will be displayed. The pop-up message will appear as follows:

When connecting HYAMP III to HYPOT III the 38075 Interlock connectors may no longer be used. The 38142 Interlock connectors provided with the kit will replace these parts.

48

When HYPOT III is connected to HYAMP III, the HYPOT III should have PLC remote turned on. In this configuration, you will only be able to start and reset the HYAMP III from the HYAMP III. It is possible to reset or abort the Hipot from both instruments.

7.3.1. Sequential and Simultaneous Testing

Hipot Start parameter

The Hipot start parameter, found in the system menu, controls whether the Hipot test will run sequentially after the Hyamp test or simultaneously with the Hyamp test. Please refer to section 4.1 Setup System for instruction on how to set this parameter.

The Hipot Start parameter is only used when connecting the HYAMP III with an

Associated Research Hypot. The parameter controls if the Hypot will run after the

HYAMP III has completed its test, G

→W, or if the Hypot will run at the same time as the

HYAMP III, G + W.

The Hipot Start parameter directly controls the Start output relay. Setting the Hipot start parameter to G

→W will momentarily close the start output relay at the end of the

HYAMP III test. Setting the Hipot start parameter to G + W will momentarily close the start output relay at the start of the HYAMP III test.
