WARNING
Hazardous voltages may be present when covers are removed. Qualified personnel must use extreme caution when servicing this equ Circuit boards, test points, and output voltages also may be floating above (below) chassis ground.
WARNING
The equipment used contains ESD sensitive parts. When installing equipment, follow ESD Safety Procedures. Electrostatic discharges might cause damage to the equipment.
Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your particular application.
ipment.
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform installation
and servicing. Ensure that the AC power line ground is connected properly to the Power Rack input connector or chassis.
Similarly, other power ground lines including those to application and maintenance equipment must be grounded
properly for both personnel and equipment safety. Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any cable. In normal operation, the operator does not have access to hazardous voltages within the chassis. However,
depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO HUMAN SAFETY may be normally generated on the output terminals. The customer/user must ensure that the output power lines are labeled properly as to the safety hazards and that any inadvertent contact with hazardous voltages is eliminated.
Guard against risks of electrical shock during open cover checks by not touching any portion of the electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety glasses during open cover checks to avoid personal injury by any sudden component failure.
Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary sales organizations can accept any responsibility for personnel, material or inconsequential injury, loss or damage that results from improper use of the equipment and accessories.

MX Series 10
1. Introduction
This instruction manual contains information on the installation, operation, calibration and maintenance of all power systems that use the MX Series power sources with the programmable controller.
1.1 General Description
The MX Series AC and DC power source systems are high efficiency, floor standing AC and DC power sources that provide a precise output with low distortion. Available voltage ranges are 150 Vac, 300 Vac and 400 Vac in AC mode and 200 Vdc and 400 Vdc in DC mode. The MX30-3Pi and MX45­3Pi can operate in either single or three-phase mode. The MX30 and MX45 is also available in just single or three-phase mode. All other models always operate in three-phase mode.
Models with a -1 or -3 designation provide full front panel operation but do not include certain features such as arbitrary waveform generation unless added as an option at the time of order. Models with the Pi controller offer several additional standard features, including the RS232C, USB, LAN (option) and IEEE-488 interfaces, arbitrary waveform generation, dual voltage ranges and additional measurement functions.
The MX Series units are contained in a compact floor standing enclosure on casters. This allows the units to be moved around more easily.
Read the installation instructions carefully before attempting to install and operate the MX Series power systems.
1.2 Manual organization and format
All user documentation for California Instruments power sources is provided on CDROM in electronic format. (Adobe Portable Document Format) The required Adobe PDF viewer is supplied on the same CDROM. This manual may be printed for personal use if a hardcopy is desired. To request a hardcopy from AMETEK Programmable Power, contact customer service at
service@programmablepowwer.com
This manual contains sections on installation, normal use, maintenance and calibration. If the MX system is equipped with a GPIB, RS232C, USB or LAN interface, refer to the MX Programming manual for information on using the remote control interfaces and command syntax. The programming manual is provided on the same CDROM as this user manual.
. There will be an additional charge for printed manuals.
MX Series 11
1.3 Different Model Series
There are two versions of the MX Series product, Series I and Series II. This user manual covers both MX model series with top level assembly part numbers 7003-400 (Series I) and 7003-422 (Series II). The difference between the Series I and the Series II is the controller used. The Series II uses a newer controller design but retains backward compatibility with the Series I products. The part number is shown on the model / serial number tag on the back of the MX series. All Series II will have a firmware revision of 4.0 or higher. The firmware revision is displayed briefly at power up on the LCD display and can also be queried over the bus by using the *IDN? command.
Differences between the two model series are restricted to:
x Reduced number of measurement calibration coefficients on Series II.
x Increased measurement sampling rate on Series II.
x Maximum DC offset range in AC+DC mode is 250Vdc on Series I, 220Vdc on Series II
Where relevant, differences are highlighted throughout the user manual.

2. Specifications
Specifications shown are valid over an ambient temperature range of 25 r 5q C and apply after a 30 minute warm-up time. Unless otherwise noted, all specifications are per phase for sine wave output into a resistive load. For three phase configurations or mode of operation, all specifications are for Line to Neutral (L-N) and phase angle specifications are valid under balanced load conditions only.
Note: Specifications for input and output current and power on MX180, MX225 and MX270 configurations are 4, 5 and 6 times those of MX45-3 and are not separately listed.

Repetitive Peak Current
Note: Maximum Peak Current shown. Value shown reflects absolute peak current protection level. This level may not be reached under all load conditions. Depending on load conditions, peak current may max out at lower levels due to amplifier output impedance. Note: As of firmware revision 4.52, a repetitive peak current limit function is provided which will generate a fault and shut
off the power supply if the peak current drawn by the load exceeds the maximum level for more than 30 seconds. During this time, the amplifier will limit the peak current at a somewhat level above the maximum level but it is not allowable to run in this m startup/inrush load conditions.

2.6.6 SNK Option Specifications
The –SNK or current sink option enables the MX power source to sink current from the unit under test. This mode of operation is particularly useful when testing grid-tied products that feed energy back onto the grid. The ability of the MX to simulate the grid provides unique opportunities to test the EUT for compatibility to commonly occurring line anomalies like voltage and/or frequency fluctuations. Examples of these types of EUT are inverters (PV Solar, Wind) hybrid drive systems, regenerative breaks.
The SNK option requires special amplifiers that have a different control loop from the standard MX amplifiers. Consequently, the upper frequency limit of an MX configured with the –SNK option is 500Hz as opposed to the standard 819Hz. Also, the voltage distortion levels are slightly higher than on MX units without this option.

2.7.3 Output Noise Spectrum
The MX series is a switching power supply and as such will have a certain amount of switching noise at its output. While the overall RMS noise is specified, the specific noise spectrum will differ slightly from unit to unit. The information provided in this section is for reference only.
The output noise can be reduced by using one or more external filters. A suitable filter is the P/N 7003-424-1 (Figure 2-12) available as an option. Attenuation at the 250 kHz ripple frequency is 20 dBuV. The output voltage drop at 800 Hz full load is less than 1Vrms.
Typical output noise spectrum for a standard MX45-3Pi in three phase mode operating at 400 Hz is shown in Figure 2-13 for phase A and Neutral. The same output with the use of the optional filter is shown in Figure 2-14. For connection information, refer to section 3.14.

MX Series 40
User Manual – Rev AV AMETEK Programmable Power
3.3 Mechanical Installation
The MX's are completely self-contained power sources. They are to be used free standing on a solid surface. The units are fan cooled, drawing air in from the front and exhausting at the rear.
The front and back of each unit must be kept clear of obstruction and a 6” clearance must be
maintained to the rear. Special consideration of overall airflow characteristics and the resultant internal heat rise must be considered at all times to avoid self heating and over temperature problems.
3.4 AC Input Connections and Wiring
Three-phase Delta or Y AC input voltage of sufficient amperage (consult AC input specifications for maximum AC current per phase) is required to power the MX Series.
Note: AC power should be routed through a properly sized and rated three-phase
PROTECTIVE CIRCUIT BREAKER or similar branch circuit protection device with disconnect capability. This will protect building wiring and other circuits from possible damage or shutdown in case of a system problem. It will also facilitate removing AC input power to the MX system in case of service or reconfiguration requirements.
Note: AC input wiring and connections must conform to local electrical safety codes
that apply. Always consult a qualified electrician prior to installation of any MX System.
AC input connections are to be made directly to the input fuse block. The input fuse block is located on the lower left hand corner of the front of the MX chassis. To access the input fuse connection block, the protective front cover needs to be removed first.
CAUTION: Always disconnect any input power completely when removing
any protective cover and allow the internal capacitors to fully discharge (minimum of 15 mins) before removing any cover.) See Figure 3-2 for details.
No wiring for AC input connections is provided with the MX Series and must be provided by the end user or installer. Input wiring should be entered through the right hand side (when facing the back of the MX cabinet, see Figure 3-4) wire access opening located at the rear bottom of the MX chassis. A wire channel (marked as [2] in figure below) is provided below the input transformer to allow the input wiring to be routed to the front of the unit where the connections are to be made.
WARNING: The power source's input connection wiring gage (size)
must be sized for the maximum input current rating to ensure user safety and avoid possible power source damage, regardless of the actual output load.

Note: DO NOT USE THE NEUTRAL CONNECTION OF A 3 PHASE Y AC POWER
CONNECTION IN PLACE OF A TRUE EARTH GROUND CONNECTION. AC power system neutrals cannot be used for protective earth ground.
The mains source must have a current rating equal to or greater than the input fuses and the input wiring must be sized to satisfy the applicable electrical codes. The front cover must be re­installed prior to use and the strain relief provisions located at the rear bottom of the unit must be used to maintain protection against hazardous conditions.

The input power cables and protective circuit breaker used must be large enough to handle the input current and input voltage of the power source and must conform to local electrical codes. Consult a qualified electrician prior to installation. Table 3-1 shows the size of the cables that may be used per MX cabinet. Note that wires must be sized to accommodate the worst-case maximum current that may occur under low line conditions. Local electrical codes may also require different wire types and sizes. These ratings should also be used when selecting a circuit breaker or equivalent disconnect device.
Cable lengths must not exceed twenty-five (25) feet. For lengths greater than 25 feet, calculate the voltage drop from the following formula:
2 X DISTANCE X CABLE RESISTANCE PER FT. X CURRENT = VOLT DROP

Circular Mils
(Kcmils)

* Using high temperature rated wire. Always consult the National Electrical Code and/or local code regulations for proper rating and size of wire cabling prior to installation.
CAUTION: Capacitors in the power source may hold a hazardous electrical charge
even if the power source has been disconnected from the mains supply. Allow capacitors to discharge to a safe voltage before touching exposed pins of mains supply connectors. Power modules need at least 15 Minutes to discharge to safe levels before they can be removed.
3.5 AC On/Off Circuit Breaker on MX Series front panel.
It is important to understand the purpose and operation of the On/Off circuit breaker of the MX Series located on the lower left side of the front panel. This is a 2A rated breaker that is used to engage and protect the LV Power supply of the MX chassis only. The LV Power supply provides DC bias power to the entire MX system. The AC input power is routed through a set of three AC line fuses (F1, F2 and F3) located in the lower left bottom corner of the MX. (See Figure 3-2 for fuse locations). These fuses protect the three MX amplifiers and the AC input transformer from excessive input currents. The AC input power is connected to the input transformer through a large three-pole contactor. Removing AC power to the LV Power Supply by opening the front panel circuit breaker (moving the lever to the down (OFF) position) will cause this contactor to loose its coil voltage and will result in it opening and disconnecting the input transformer and amplifier from AC mains input.
Note: If any MX system failure has occurred on any part of the MX system, AC input
power must be removed immediately and not restored until the system has been inspected by a qualifier service technician. Always turn off the On/Off Circuit breaker before re-applying AC input power.
MX Series 44
User Manual – Rev AV AMETEK Programmable Power
CAUTION: The AC input fuses can only be checked is the MX unit is completely
de-energized and disconnected from any AC power input.
Note: Under no circumstances should AC input power be applied if one or more of the
AC input line fuses have failed and opened up.

3.6 Output Connections
3.6.1 Output Wiring
The output terminal blocks, TB1A and TB1B are located at the front of the unit behind the bottom access panel. See Figure 3-2 for details.
Three phase output line connections are made to terminal block TB1A. The phase outputs are labeled A, B and C. The neutral connection (if needed) can be made on terminal block TB1B. If the model used is an MX30-1, MX30-3Pi, MX45-1 or MX45-3Pi with single-phase capability, the single phase A output connection is available on TB1B as well. Note that the neutral for either single or three-phase mode is always located on TB1B. The neutral connection is always required for single-phase output mode on an MX30-3Pi or MX45-3Pi and may be used if needed for the EUT for all three-phase output modes.
The external sense inputs allow the power system output voltages to be monitored directly at the load and must be connected at TB2 when the sense is programmed for external. The external sense input does not have to be connected when Internal Sense is programmed. The external sense wires are to be connected to TB2 on the rear panel and should be run using a twisted shielded cable. See Figure 3-4 for location of TB2 and Figure 3-5 for shield connection detail.
Note: For External Sense connection, a shielded cable MUST be used with the shield
connected to chassis ground at the Ext. Sense connector. (See Figure 3-5).
External sense is recommended for multi-cabinet systems is the output wiring from the cabinets to the common output terminal block supplied is not of equal length.
Figure 3-5: External sense cable shield connection to chassis ground
Note: The output of the power source is isolated from the input line and floating with
respect to chassis ground. If needed, either side (HI or LO) may be grounded.
If the EUT changes frequently, you may want to consider using some quick disconnect scheme external to the MX so it will not be necessary to power down the MX and remove the front covers. This can take the form of a panel-mounted socket (1 or 3 phase) of sufficient current and voltage rating. (Not supplied with MX)

The output power cables must be large enough to prevent a total voltage drop exceeding 1% of the rated output voltage between the power source and the load. Table 3-2 shows the size of the cables that may be used. Note that wires must be sized to accommodate the maximum current that is available. This may be a function of the voltage range and phase mode on some MX models. If the MX has more than one output voltage range, size the wires for the lowest available voltage range as the currents will be highest in that range.
Cable lengths must not exceed twenty-five (25) feet. For lengths greater than 25 feet, calculate the voltage drop from the following formula:
2 X DISTANCE X CABLE RESISTANCE PER FT. X CURRENT = VOLT DROP

3.6.7 Multi-Chassis Output Connections
If two or more MX chassis are used to form a single power system, the outputs of all chassis need to be combined (paralleled by phase). This can be done directly at the EUT if convenient or using the provided heavy-duty terminal blocks. Two blocks are provided with multi-chassis MX systems, one 2-position block and one 3-position block. These blocks allow up to four wires to be combined into one larger wire gauge size wire. The outputs of the 2 or 3 MX chassis are connected on one side of these blocks (Phase A,B and C into the 3 position terminal and the neutral into the 2 position terminal.). The EUT can be connected to the other side. Note that the wire size to the EUT should be sized up to accommodate the double or triple currents per phase.
The dimensions of the supplied terminal blocks are shown in Figure 3-14.
Note that even if the EUT is a three-phase delta input, the output neutrals of the MX chassis' must be connected together for the system to work correctly.

3.7 Connectors - Rear Panel
A number of connectors are located along the top rear covers. These connectors are in a recessed area to protect them from shipment damage.
3.7.1 System Interface
WARNING: The system interface connectors are for use with AMETEK Programmable
Power supplied cables, and only between California Instruments equipment.
The Clock and Lock BNC connectors located on the rear panel are used to synchronize and control the phase shift between the three outputs when 3 units are operating as a three-phase clock and lock system. This mode of operation requires the -LKM (on Master unit) and -LKS (on Auxiliary units) options. See paragraph 3.10 for more information on this mode of operation.
A set of two identical System Interface connectors, P8 and P9 is located on the rear panel of each MX chassis. The system interface is used to connect the multiple MX30 or MX45 power sources in a Master/Auxiliary configuration to create MX60, MX90 or MX135 models. In these configurations, only the Master MX30 or MX45 power source has a built-in controller and front panel.
The same connector is also used to control the optional OMNI-3-75 Reference Impedance.

3.8 Multiple Cabinet System Configurations (incl. –MB)
Multi-cabinet MX models consist of two or three autonomous or Auxiliary MX45-3Pi units. Auxiliary units do not have their own controller and are identified easily by their blank front panel (except for status indicator LEDs). Master units each have their own controller but can be configured as auxiliary units by disconnecting the ribbon cable marked J17 between the controller and the system interface board (P/N 7003-700-1 or P/N 7003-715-1). This disables the controller and allows the MX45 to operate as an Auxiliary unit. (Requires removal of the top cover). See section 4.2.11.5 for information on setting the SYSTEM field in the configuration menu when changing configurations on MX systems with the –MB (Multi-box) option.
When used as a multi-cabinet system for higher power applications, the controllers in the unit(s) acting as the auxiliary to the master are either disabled or not present. For normal system configurations such as MX90-3Pi, the auxiliary unit will not have a controller or front panel and will have been factory configured for auxiliary operation.
For –MB systems such as MX90-3Pi-MB, the controller in the auxiliary unit must be disabled using S1. The SYSTEM field in the master unit controllers CONFIGURATION SETUP 3 screen must be set to the correct system configuration setting as well. The SYSTEM field for the controller in the auxiliary unit must be set to AUX if it is used as an auxiliary unit. See section
4.2.11.5.
Note: New SYSTEM field configuration settings do not take effect until power is cycled.
In addition to disabling the controller if present (as described above), the DIP switch (S1) located on the GPIB / RS232C / IO assembly in the auxiliary cabinets. (Requires removal of the top cover). The correct switch settings are shown below. (shown set for Master cabinet). Note that all units must be powered down before reconfiguring. Also, the output wiring must be changed to accommodate the new configuration.
Note: If the units being re-configured for multi-cabinet operation were not factory
configured this way, it may be necessary to balance the amplifiers by adjusting their gain. Refer to section 6.4 for details on Amplifier balancing.
When used as a multi-cabinet system, the system interface cables must be connected between the master and the auxiliary cabinets.
Note: If the –MB system has the –ES emergency shut off switch option, it is required to
connect the ES BNC’s between master chassis. See section 3.7.8.

3.9 Multiple Cabinet Power Up/Down Procedures
For all multi-cabinet MX Series configurations (MX60, MX90, MX135, MX180, MX225 and MX270), the following Power Up (Turn on) and Power Down (Turn off) procedures should be observed.
3.9.1 Power Up Procedure
Follow these steps:
1. Turn on each of the Auxiliary units using the front panel circuit breaker, one at a time. The exact order for turning on the auxiliary units is not important. Note that the bias supplies of each of the auxiliary cabinets will power up but not the actual amplifiers. This is because the auxiliary units are waiting for the turn on signal from the master unit.
2. Once all auxiliary units are on, turn on the MASTER unit LAST using the front panel circuit breaker. The master unit will go through an initialization process and power up itself plus the auxiliary units.
3. Allow 20 to 30 seconds for the turn on sequence to complete before attempting to communicate with the system.
3.9.2 Power Down Procedure
The power-down / shutdown sequence for the system is the reverse of the power-up / turn-on sequence. This means the MASTER unit is turned off FIRST. Once the MASTER shuts down, all auxiliary units’ main AC input power contactors will open up automatically. They still need to be turned off individually using the front panel circuit breaker. This will shut down their bias supplies as well.
Follow these steps:
1. Disconnect the EUT by opening the MX output relay. Use the Output On/Off button on the master unit front panel or send the “OUTPUT 0” command over the bus to do so.
2. Turn off the MASTER unit FIRST using the front panel circuit breaker. The master unit will disengage the main AC power input contactors of all auxiliary units at this time.
3. Next, turn off each of the Auxiliary units using the front panel circuit breaker, one at a time. The exact order for turning off the auxiliary units is not important.

ON
Auxiliary MX. Frequency mode selection is
INT (internal = for stand alone use) or EXT (external for Clock and Lock mode operation.)
3.10 Clock and Lock Configurations
The MX Series may optionally be equipped for clock and lock mode of operation. This mode is a special form of Master/Auxiliary, which requires each chassis to have its controller. As such, it is possible to create 2, 3, 6 or 9 phase power systems using 2 to 3 MX chassis. For most 2 or 3 phase configurations, the normal multi-box mode of operation as described in section 3.8 is recommended as it provides a single controller (and GPIB/RS232 control interface).
In a clock and lock configuration, each unit has its own front panel controls (as well as individual GPIB and RS232C interfaces) for operating the supply but the output frequency of the auxiliary unit(s) (-LKS option) is synchronized (locked) tot he Master MX unit (-LKM).
This mode of operation requires that one MX has the -LKM (Lock Master) option and one or two MX units have the -LKS (Lock auxiliary) option.
3.10.1 Clock/Lock Configuration Settings
Clock and lock configuration. settings for -LKM and -LKS equipped MX's are set at the factory at the time of shipment and cannot be changed. To check the configuration settings for an MX, select the UTILITY2, CONFIGURATION screen. In the configuration screen, the CLK/LOC entry determines if the unit is a Master or Auxiliary as follows:
Table 3-13: Clock and Lock Configuration settings
Note that the actual mode of operation of a Clock/Lock MX-LKM auxiliary unit is determined by the Clock mode set in the PROGRAM2 screen. For clock and lock mode of operation, the master is set to INT and the Auxiliary to EXT.

MASTER
For master (-LKM) power source in clock and lock mode of operation.
AUX
For auxiliary (-LKS) power source in clock and lock mode of operation. Powers up with clock mode set to external.
3.10.2 Clock/Lock Initialization Settings
The mode of operation of the MX-LKS auxiliary unit is determined by the Clock mode set in the PROGRAM2 screen. Since most clock and lock systems are permanently used in this configuration, the clock mode can be set to EXT (External) at power on by using the INITIAL SETUP3 screen.
Available initial settings and their relationship to the Clock and Lock mode of operation are shown in the table below.
Table 3-14: Clock and Lock Initialization settings
3.10.3 Clock/Lock and External Sync Mode
Note that an MX-LKM auxiliary unit is factory configured to operate in Clock and Lock mode when EXT clock mode is selected in the PROGRAM2 screen. This means that a MX-LKS cannot be used in normal external sync mode. However, the MX-LKM master unit can be operated in external sync mode. Note: External sync mode is not available with the FC
option.
Furthermore, since the MX-LKM master unit is factory set for Master mode of operation, it in turn cannot be used as an Auxiliary source in a clock and lock configuration.
3.10.4 Remote Programming of Clock and Lock systems
Since clock and lock systems have multiple autonomous controllers that are synchronized in frequency, remote programming of these systems requires that the application program deals with all MX controllers. This often precludes the use of RS232C as generally not enough serial ports are available. The use of GPIB instead also offers the advantage of using the Group Execute Trigger (GET) capability to effect output changes on all phases (MX's) simultaneously which is otherwise difficult to do.
To set up a GPIB remote controlled clock and lock systems, the GPIB addresses for the individual MX's must be set to different address values in the UTILITY1, GPIB/RS232 SETUP screen.

3.11 Basic Initial Functional Test
CAUTION: Work carefully when performing these tests; hazardous voltages
are present on the input and output during this test.
Refer to Figure 3-19 for the required functional test set up. Proceed as follows to perform a basic function check of the power system:
1. Verify the correct AC line input rating on the nameplate of the MX unit(s) and make sure the correct three-phase line voltage is wired to the input of the MX before applying input power.
2. Connect a suitable resistive or other type load to the output of the MX. The load resistance value will depend on the voltage range you plan to check. Make sure the power resistor has sufficient power dissipation capability - up to 15 KW for full load test on one phase of MX45-3 or 10 KW for full load test on one phase of M30-3Pi - and that the load used does not exceed the maximum power rating of the MX. For three phase configurations, this test can be performed on one phase at a time if needed.
3. Connect an oscilloscope and DMM / voltmeter to the AC source output. Set both for AC mode.
4. If the correct voltage is present, turn on the MX unit(s) by closing the On/Off circuit breaker on the front panel. For multi-cabinet systems, turn on the auxiliary unit first and wait for them to cycle on, then turn on the master unit.
5. If the MX has more than one available output voltage range, go to the PROGRAM 1 screen and select the desired voltage range. The output mode can be set from the PROGRAM 2 screen (use the MORE soft key or press the PROGR function key again). Select AC mode.
6. Set the output voltage to 0 volt and close the output relay with the OUTPUT ON/OFF button. There should be little or no output although the DMM may show a noise level, especially if the DMM is in auto ranging mode.
7. Move the cursor to the VOLTAGE field in the PROGRAM 1 screen and either use the keyboard to program a small voltage (20 VAC) or slew the voltage up slowly with the knob. Observe the DMM reading. The reading should track the programmed voltage.
8. Also monitor the scope. The output should be a sinusoidal voltage waveform.
9. If the output tracks, increase the voltage till you reach 80 % of the voltage range or more. Check the output voltage reading and waveform.
10. Select the MEASUREMENT 1 screen by pressing the MEAS button. The output voltage, current and power will be displayed. For three phase configurations, use the PHASE button to select the øABC display mode. This will show the voltage, current and power for all three phases. If all phases are loaded equally, the same current and power should be visible for all three unless the voltages are not programmed to the same level. If only one phase is loaded, current and power will only be shown for the loaded phase.

MODE
OPERATION
LATCHING
A TTL low at the RI input latches the output in the protection shutdown state. This state can only be cleared by sending a OUTPut:PROTection:CLEar command over the bus.
LIVE
The output state follows the state of the RI input. A TTL low or contact closure at the RI input turns the output off; a TTL high or open contact turns the output on. This mode is equivalent to using the Output On/Off button on the front panel. Default mode. Units are shipped in this mode.
OFF The instrument ignores the RI input.
3.12 Remote Inhibit / Remote Shutdown
It may be necessary to provide a remote shutdown of the AC or DC output of the MX. The external remote inhibit input may be used for this purpose (RI). This input is also referred to as remote shutdown.
The default mode of operation for the RI input is a contact closure between pins 5 and 6 (return) of the rear panel screw-terminal strip. This will open the output relay of the MX.
If the firmware revision of the MX is 0.28 or higher, it is possible to reverse the polarity of the RI input. This requires the use of the following bus command:
OUTPut:RI[:LEVel] HIGH /* Sets RI polarity to active high.
OUTPut:RI[:LEVel] LOW /* Sets RI polarity to active low (Factory default)
The remote control interface must be used to change this setting. Once set, the polarity setting remains in effect. On units with firmware rev 0.27 or lower, this input level mode selection is not available.
MX Series I
When set to HIGH, an active low TTL level or a contact closure is required to enable the output relay of the MX. Opening the contact or removing the low input signal will cause the output relay to open.
MX Series II
The way the MX responds to a remote inhibit event can be programmed over the remote control interface using the OUTP:RI:MODE command. See 7003-961 programming manual for details on changing modes. The mode set is retained at power off and recalled at power up so stays in effect till changed again over the bus.
The following modes are supported.
Table 3-15: Remote Inhibit Mode Settings
NOTE: When using the Remote Inhibit input, it will be necessary to disconnect any RI
connection to the MX master unit when turning on the MX master unit. During initialization, the RI connection must be OPEN
or initialization will be halted with
the message WARING FOR AUXILIARY displayed on the LCD screen.

3.13 Junction Box Accessory
An optional wiring junction box (P/N 7003-416-1) is available which may be used to connect the outputs of 2 to 6 MX cabinets together. The junction box also has a protective ground connection, which MUST be connected to a suitable protective earth ground.
Each junction box has four sets of terminals for phase A, phase B, phase C and Neutral. Each terminal is lined up with a strain relief on each side. The outputs from the MX45 cabinets connect
to the “MX SYSTEM OUTPUT” side of these terminal blocks. The load can be connected to the “LOAD”. Note that the wiring is not supplied with the system and must be provided by the end
user. The wire gauge of the load connection must be sized to handle the maximum current in the low voltage range of operation.
The “MX SYSTEM OUTPUT” side of the terminal block will accept up to 8 wires. If the external
sense connection is made at the junction box, one of these can be used to connect the sense wiring.
Note: Do not swap output load wires or sense wires between phases, as damage to the system will result.
The “LOAD” side will accept 2 wires. The wire size range shown in Figure 3-20 refers to mechanical compatibility of terminal block only. This information does not reflect required wire size. The wire sizes accepted by the terminal blocks of the junction box on each side are shown in Figure 3-20.

3.14 Output Filter Box Accessory
An optional output filter box (P/N 7003-424-1) is available which may be used reduce the amount of ripple and noise present at the output of the MX30/45-3Pi.
The filter must be connected between the three-phase output of the MX30/45 and the unit under test. To access the connection terminal blocks, the top cover of the filter case must be removed.
Note: Make sure all power is off when connecting the filter accessory.
The output of the MX30/45 is connected to the input side of the filter. Use terminal blocks TB1A (phases A and B) and TB1B (phase C and neutral) as indicated in Figure 3-21. The load can be connected to the load side of the filter box using terminal blocks TB2A and TB2B. Do not swap phases through the filter.
To compensate for voltage drop across the filter, the external sense connections can be made at the load (load side of the filter).
Note: The filter box chassis must be connected to earth ground.
It is not recommended to use the ground connection on the MX30//45 itself for this purpose but rather a ground point at the AC service to the MX30/45.

4. Front Panel Operation
4.1 Tour of the Front Panel
The MX Series with type P or type Pi have identical front panels although some of the keys found on the front panel are only used by MX models with the 3Pi controller. If your unit is a P type
controller, these keys will act as don’t cares. This chapter provides information on operating the
MX with either controller type.
Before operating the AC source using the front panel, it helps to understand the operation of the front panel controls. Specifically, the operation of the knob, keyboard and the menu layout are covered in the next few paragraphs.
4.1.1 Front Panel Controls and Indicators
The front panel can be divided in a small number of functional areas:
x Mains circuit breaker
x Status Indicator lights
x Shuttle knob
x LCD display
x FUNCTION keypad
x DATA ENTRY keypad
4.1.2 System On/Off Circuit Breaker
The circuit breaker located on the bottom left side of the front panel disconnects the low voltage supply of the MX Source from the three phase Line input. This will remove power from the mains AC input contactor and thus remove input power from the MX Series power source. As such, the circuit breaker acts as an indirect power on/off switch for the MX Series unit. Note however than AC input power remains applied to the primary side of the input transformer.
When the input current rating of the MX Series AC power source is exceeded, the protective fuses (F1 through F3) will blow. In this case, power to the low voltage supply may still remain through the front panel circuit breaker. In this case, the on/off circuit breaker should be opened (power off) first followed by a complete disconnect of all ac input power through an installed main circuit breaker.
Note that in MX60, MX90 and MX135 systems, each unit has its own on/off circuit breaker and set of line input fuses.
MX Series 80
User Manual – Rev AV AMETEK Programmable Power
4.1.3 Status Indicator Lights
Four LED status indicators are located directly above the mains circuit breaker. These LED’s correspond to the following conditions:
REMOTE The REMOTE LED indicates that the unit is in remote control
mode. If the IEEE-488 interface is used, this indicator will be lit whenever the REM line (REMOTE ENABLE) line is asserted by the IEEE controller. If the RS232, USB or LAN interface is used, the REMOTE state can be enabled by the controller using the SYST:REM command. Any time the REMOTE LED is lit, the front panel of the MX Series unit is disabled. There is no LOCAL button that allows the user to regain control of the front panel. This prevents accidental change of settings in ATE applications.
OVERLOAD The OVERLOAD LED indicates an output overload condition.
This condition can be controlled by setting the current limit value in the PROGRAM menu. Removing the load using the OUTPUT ON/OFF button will recover from an overload condition.
OVER TEMPERATURE The OVER TEMPERATURE LED indicates an overheating
problem inside the unit. This is an abnormal condition, which will cause the unit to shut off. Check the air openings to make sure they are not blocked.
HI RANGE The HI RANGE LED is on when the high voltage output range
has been selected.

Figure 4-1: Shuttle Knob
The shuttle knob is located to the right of the LCD screen and is used to change setup parameters. Note that it cannot be used to move the cursor position between menu fields. Use the UP and DOWN arrow keys in the FUNCTION keypad for this.
The shuttle knob can operate in one of two distinct modes of operation:
MODE DESCRIPTION
IMMEDIATE mode Any time the ENTER key is pressed, the MX Series returns to its
normal mode of operation. In this mode, changes made with the shuttle knob or the data entry keypad will take immediate effect. The IMMEDIATE mode is useful for slewing output values such as voltage and frequency and observing the effect on the load.
SET mode When the SET key located in the FUNCTION keypad is
pressed, changes made with the shuttle to any output parameter will not take effect until the ENTER key is pressed. In this mode, any changes made to a setup menu will be blinking to indicate the pending change condition. This mode allows changes to be made to all output parameters and executing them all at once by pressing the ENTER key.

KEY DESCRIPTION
MENU The top level menu is accessed by pressing the MENU key.
Three shortcut keys are used to provide direct access to the PROGRAM, WAVEFORM, and MEASUREMENT screens as these are among the most frequently used screens. Thus, instead of going through the main menu to reach the PROGRAM, WAVEFORM, and MEASUREMENT screens, they can be accessed directly by pressing the PROG, WAVE, and MEAS keys respectively. A map of the Main menus is provided on the next few pages. There are three top level menus in the MX Series.
PROG The PROG key is a shortcut to access the PROGRAM menu
directly. The PROGRAM menu is one of the most frequently used menus. Thus, instead of going through the main menu to reach the PROGRAM menu, it can be accessed directly by pressing the PROG key.
WAVE The WAVE key is a shortcut to access the WAVEFORM screen
directly. The WAVEFORM screen is used to select a user defined arbitrary waveform. (3Pi controller only)
MEAS The MEAS key is a shortcut to access the MEASUREMENT
screen directly. The MEASUREMENT screen is one of the most frequently used screens. Thus, instead of going through the main menu to reach the MEASUREMENT screen, it can be accessed directly by pressing the MEAS key.
MX Series 83
User Manual – Rev AV AMETEK Programmable Power
OUTPUT ON/OFF The OUTPUT ON/OFF key toggles the output relay on or off.
The state of the output relay is reflected by the green LED located directly to the left of the OUTPUT ON/OFF key. If the green LED is lit, the output relay is enabled (closed) and the programmed output voltage is present at the output terminals. If the green LED is off, the output relay is open and both the HIGH and LO terminal of the output terminal block are disconnected from the power source. In this mode, the output is floating. The ON/OFF button provides a convenient way to disconnect the load without having to remove any wires.
PHASE The PHASE key is used to select the phase on a MX30-3Pi or
MX45-3Pi model. Pressing the PHASE key will toggle phase A, B, C or ABC. Some screens may not support the ABC or show all phase information in which case this mode is skipped. (3Pi controller only)
SET The SET key is used to select the mode of operation of the
shuttle. Refer to section 4.1.1 for details on its operation and the use of the SET key.
+/- The +/- key can be used to toggle the sign for those parameters
for which it is relevant. This is typically the output voltage when in DC mode of operation. For fields that have only two possible values such as the voltage range field, the +/- key can be used to toggle between these two values.

The decimal keypad can be used at any time in lieu of the shuttle knob to change output parameters. Direct data entry is often faster to effect large changes in values than using the shuttle knob. Note that pressing the ENTER key while in SET mode of operation will cause the AC source to revert back to IMMEDIATE mode. Thus, to change all parameters in SET mode, enter a value for each field and then proceed to the next field without pressing the ENTER key.

4.1.7 LCD Display
The LCD display of the MX Series power source provides information on instrument settings and also guides the user through the various menus. To ease reading of the displayed information, most screens are widely spaced. A sample of the main menu 1 screen that appears when the MX Series source is powered up is shown in Figure 4-6. Due to the amount of space available on each screen, some menus have been split into parts. The MORE selection located at the bottom right hand side provides access to menu choices at the same level that did not fit on a single
screen. Thus, to access MENU 2, the cursor should be placed on the ‘MORE’ selection followed by pressing the ‘ENTER’ key. Alternatively, the MENU key may be pressed to move to the
MENU 2 screen.
The present cursor position is always shown with a inverse bar. The cursor is located on the ‘MORE’ selection in Figure 4-6. Pressing ENTER would cause MENU 2 to be displayed.
The cursor position can be moved by using the UP and DOWN keys located in the DECIMAL keypad.

4.2 Menu Structure
The next few pages show a map of the available menus in the MX Series. There are three main level (level 1) menus from which all other menus can be reached. Frequently used (level 2) menus have a short cut key that provides direct access. Examples of such menus are Program, Measurements, and Waveform. In any case, there are never more than three levels of menus although some menus may be spread across more than one screen.
4.2.1 MAIN Menus
Figure 4-7: Menu 1 through 3
The top-level menu is split in three parts, MENU 1 through MENU 3 to allow spacing between menu entries. MENU 2 and 3 can be reached from MENU 1 by selecting the MORE entry or by pressing the MENU key repeatedly, which will toggle from MENU 1 to 2 to 3 and back to 1. The division of menu choices between the two screens is graphically illustrated in 4.2.2 by the boxes in level 1. Each box represents one screen. Subsequent screens can be reached using the MORE entry.

4.2.4 PROGRAM Menu
Figure 4-8: PROGRAM Menu
The PROGRAM menu is shown in Figure 4-8. It can be reached in one of two ways:
1. by selecting the PROGRAM entry in the MENU screen and pressing the ENTER key
2. by pressing the PROG key in the FUNCTION keypad
The PROGRAM menu is used to change output parameters. The most commonly used parameters are all located in PROGRAM 1. The PREVIOUS SCREEN entry, when selected, will return the user to the most recently selected menu. This is normally the MENU screen unless the PROGRAM menu was selected using the PROG key on the FUNCTION keypad. Less frequently used parameters are located in PROGRAM 2, which can be reached from the PROGRAM 1 screen using the MORE selection, or by pressing the PROGRAM key twice.
The following choices are available in the PROGRAM menus:
Entry Description
PROGRAM 1
VOLTAGE Programs the output voltage in Vrms while in AC mode or
absolute voltage when in DC mode. In DC mode, negative values can be entered.
FREQ Programs the output frequency when in AC mode. If the unit is
in DC mode, the value for FREQ will be set to DC and cannot be changed until AC mode is selected. When in AC mode, the frequency can be changed from 16 Hz to 500 Hz. Values entered that fall outside this range will generate a -200 RANGE ERROR and will not be accepted.
VOLT RANGE Selects 150V, 300V or optional 400V range in AC mode and
200V or 400V range in DC mode. The actual range values may be different depending on the configuration. The value of this field can only be changed with the shuttle or the +/- key.
MX Series 91
User Manual – Rev AV AMETEK Programmable Power
CURR LIMIT Sets the current limit value for the current detection system.
When the load current value exceeds the set current limit, a fault condition is generated. The actual response of the AC Source to a current limit fault is determined by the protection mode selected in the CONFIGURATION menu. (CC = Constant Current, CV = Constant Voltage).
PROGRAM 2
PHASE Selects the phase angle between the external clock and the
output of the AC source. If the clock source is internal, this parameter has no effect.
CLOCK MODE Selects internal or external clock source. The MX Series
controller uses an open-air crystal time base with an accuracy of 100 ppm. To improve output frequency stability and accuracy, an external clock generator may be used.
VOLT MODE The MX Series offers three output modes, AC, DC and AC+DC.
The VOLT MODE field can be used to toggle between these three output modes. Both the Knob and the +/- key may be used to toggle through these three selections. In DC mode, no frequency selection is possible and all maximum current and power ratings are divided by two.
DC OFFSET When the AC+DC mode is selected, the VOLTAGE field in the
PROGRAM 1 screen is used to set the AC portion of the output voltage. The DC OFFSET field in the PROGRAM 2 screen can be used to set the DC offset level. Either the knob or the decimal keypad may be used to set the DC offset level.
START ø Selects the start phase angle for output changes made to either
voltage or frequency. This allows changing the output at a specific phase angle. The output on key also uses this phase angle setting to program the output voltage up to the set level after the output relay is closed. The default value for this field is RANDOM.
MX Series 92
User Manual – Rev AV AMETEK Programmable Power
4.2.5 MEASUREMENTS Screens
The MX Series uses a DSP based data acquisition system to provide extensive information regarding the output of the Source. This data acquisition system digitizes the voltage and current waveforms and calculates several parameters from this digitized data. The result of these calculations is displayed in a series of measurement data screens. The actual digitized waveforms can also be displayed by selecting the Harmonics/Trace Analysis screen. A total of four measurement screens are used to display all this information (3Pi controller only).
Figure 4-9: MEASUREMENTS Screen, Single Phase and Three Phase Modes
The first three Measurement screens available on the MX Series are not menus in that no changes can be made anywhere. Instead, these three screens provide load parameter readouts. The fourth measurement screen provides access to the advanced measurements and does offer several user accessible fields (Pi controller only). The measurement screens can be reached by successively pressing the MEAS key, which will toggle to all four available screens.
In three-phase mode, measurements are available for each phase individually. To select the desired phase, use the PHASE key to toggle through phase A, B, C, or ABC. The ABC mode displays the data for all three phases simultaneously.
The following parameters are available in the first three measurement screens:
Entry Description
MEASUREMENT 1
VOLTAGE When in AC or AC+DC mode, this value is the true rms output
voltage measured at the voltage sense lines. In DC only mode, the voltage is the DC voltage including polarity.
CURRENT When in AC or AC+DC mode, this value is the true rms output
current drawn by the load. In DC only mode, the current is the DC current including polarity
FREQ When in AC or AC+DC mode, the output frequency is measured
at the sense lines. When in DC only mode, this value always reads “DC”.
POWER In both AC and DC mode, this value is the real rms. power
consumed by the load.
MEASUREMENT 2
VA POWER In AC or AC+DC mode, this value is the apparent rms. power
consumed by the load. In DC mode, this value is always the same as the POWER readout.

PEAK CURR This readout reflects the peak current value detected at the
output. To measure inrush current for a unit under test, open the output relay and reset the peak current value using the PEAK CURR RESET entry. Then program the output voltage and frequency and turn on the output relay. The peak current measurement will continuously track the maximum current value detected until reset.
POWER FACTOR This readout shows the power factor of the load.
CREST FACTOR This readout displays the ratio between peak current and rms
current.
MEASUREMENT 3 [3Pi controller only]
VOLT THD This readout displays the total voltage distortion for the selected
phase. The distortion calculation is based on the H2 through H50 with the fundamental voltage (H1) in the denominator. Note that other common definitions of THD use the RMS value of the voltage as the denominator. This may result in different readings between instruments depending on the implementation chosen. The mode used by the power source is selectable over the bus.
CURR THD This readout displays the total current distortion for the selected
phase. The distortion calculation is based on the H2 through H50 with the fundamental current (H1) in the denominator. Note that other common definitions of THD use the RMS value of the current as the denominator. This may result in different readings between instruments depending on the implementation chosen. The mode used by the power source is selectable over the bus.
INST PK CURR This readout reflects the instantaneous peak current value
detected at the output. This value is updated continuously and does not require a reset operation like the PEAK CURR readout. The instantaneous peak current does not use a track and hold mechanism like the PEAK CURR measurement in the MEASUREMENT 2 screen. Instead, it tracks the peak current on a cycle-by-cycle basis. The INST PK CURR typically tracks the rms current and the crest factor.
Update Program Functions from Measurement Screen
The Shuttle can be used to update program parameters such as voltage, frequency or current from the measurement screen. This can be achieved with the following sequence:
1. Select the program 1 screen using the PROG key.
2. Use the up and down key to select the desired function to update. (Selects parameter that will be changed by the shuttle once in the MEAS1 screen)
3. Select the measurement 1 screen by pressing the MEAS key.
4. The pointer symbol (X) points to the programmed parameter (V, F or CL) that will be affected by turning the shuttle.

TABLE mode:
Displays the first 50 harmonics in a tabular text format.
BAR mode:
Displays the first 50 harmonics in a graphical bar chart display.
TRACE mode:
Displays the selected Function in a time domain (waveform) graphical display.
HARMONICS/TRACE ANALYSIS Screen [3Pi controller only]
The fourth measurement screen is dedicated to the advanced measurements available on the MX Series with 3Pi controller only. This screen is not available on the P controllers. The Harmonics/Trace Analysis measurement screen is a true menu screen offering several user accessible fields. These fields are used to select the desired acquisition trigger and display mode. The actual data is displayed whenever the ENTER key is pressed while the cursor is on the VIEW or START field. The following fields are available on this menu:
Figure 4-10: HARMONICS/TRACE ANALYSIS Screen
Entry Description
FUNCTION Selects Voltage, Current or Both parameters for display.
VIEW Available display modes are TABLE, BAR and TRACE.
MX Series 95
User Manual – Rev AV AMETEK Programmable Power
DATA MODE Selects absolute or relative harmonics display for TABLE and
BAR view modes. In relative mode, all harmonics are shown in a percentage of the fundamental, which is normalized at 100 %. In absolute mode, the harmonic amplitudes are shown in absolute volts or amperes.
This mode does not apply to the TRACE view display mode and
is ignored when this mode is selected.
SCALE Sets the horizontal time axis for the TRACE view display mode.
The field range is: Series I: 4 ms to 104 ms in single-phase mode (MX30-3Pi or MX45-3Pi only) or 12 ms to 312 ms in three phase mode. Series II: 4 ms to 42 ms in single-phase mode (MX30-3Pi or MX45-3Pi only) or 12 ms to 128 ms in three phase mode.
This parameter is ignored when the TABLE or BAR view display
mode is selected.
TRIG MODE This field sets the trigger mode for the acquisition. Available
options are SINGLE (single shot acquisition) or CONT (continuous acquisition). In SINGLE shot mode, the acquisition is triggered once each time the START field is selected and the ENTER key is pressed. The selected trigger source is used to determine the trigger point. Once the acquisition has been triggered, the data are displayed and do not change until the next acquisition is triggered. This mode is most appropriate for single shot events such as start up currents.
In the CONT mode, acquisitions occur repeatedly and the data
is updated on screen after each trigger occurs. This provides a continuous update of the data and is most appropriate for repetitive signals.
TRIG SOURCE The trigger source selects the event that will trigger a
measurement acquisition. Available options for this field are IMM (immediate), PHASE A or SET VOLT. The IMM trigger source causes the acquisition to trigger immediately when the ENTER key is pressed on the START field. Essentially, this is an asynchronous trigger event. The acquisition will always be triggered in this mode and data is available immediately.
The PHASE A source will cause the acquisition to trigger on the
occurrence of a set phase angle for the voltage on phase A. The trigger source is always phase A when in this mode, regardless of the phase selection shown in the top right corner of the display. When the acquisition is started, the acquisition system waits for the specified phase angle to occur before triggering the acquisition. This mode allows exact positioning of the acquisition data window with respect to the voltage waveform.
The SET VOLT mode causes the acquisition to trigger at the
specified voltage. This mode also programs the selected phase or all three phases when the measurement is started from the START field. As such, this trigger source selection also programs the output voltage to the selected rms level.
TRIG PHASE / SET VOLT This field changes purpose, depending on the trigger source
MX Series 96
selected immediately above it. If the trigger source equals IMM or PHASE A, this field can be used to program the trigger phase
User Manual – Rev AV AMETEK Programmable Power
angle (TRIG PHASE). In IMM mode, the value of this field is ignored.
If the trigger source is set to SET VOLT, this field can be used
to specify the rms voltage to program the output to and trigger the measurement on. The voltage value set here should not exceed the maximum voltage range selected or the rms capability for the wave shape selected on the phase or phases programmed.
TRIG DELAY The trigger delay field allows the trigger point to be positioned
anywhere in the acquisition window. A negative value will provide pre-trigger information on data leading up to the trigger event. The pre-trigger delay cannot exceed the length of the acquisition buffer. See paragraph 4.6.3.3 for details. A positive trigger delay positions the data window after the trigger event. Positive trigger delays can exceed the length of the acquisition buffer in which case the trigger event itself will not be in the buffer any more. The maximum value of the trigger delay is 1000 ms. The default trigger delay value is 0.0 ms, which puts the trigger event at the beginning of the acquisition window.
START The START field is used to start a new acquisition run. To start
an acquisition, place the cursor on the START field and press the ENTER key. Once the ENTER key is pressed, the display toggles to the data display mode selected in the VIEW field as soon as the selected trigger event occurs. To return to the HARMONICS/TRACE ANALYSIS menu, press the ENTER key while in the data display mode.
To change display modes without triggering a new acquisition,
make the desired changes in the menu and move the cursor to the VIEW field. Once on the VIEW field, press the ENTER key. This will not trigger a new acquisition, which means the original data is retained.

4.2.6 TRANSIENTS Menu
Figure 4-11: TRANSIENTS Menu
The transient menu provides access to the transient list data. Available list length is:
Series I: Both P and Pi controllers; 32 data points. This is represented by 32 transient
step numbers from 0 through 31.
Series II: Both P and Pi controllers; 100 data points. This is represented by 100 transient
step numbers from 0 through 99.
From the Transient menu, the desired transient step type can be selected. Based on the user’s
choice, the relevant transient type sub menu will be shown. The START/EDIT SEQUENCE sub menu allows the user to review and change any transient step or execute the transient list. When executing a transient list, transient steps are executed in a ascending numerical order. Steps that are not defined are skipped.
The following entries can be found in the TRANSIENTS menu:
Entry Description
VOLT SURGE/SAG Voltage surges and sags are temporary changes in amplitude.
The output voltage will change from its present value to a user specified value for a specified duration. (Sag if the value is lower, surge if the value is higher.) After this period has expired, the output voltage returns to a user specified end value. This value may or may not be the same as the value present prior to the start of the sag or surge.
VOLT SWEEP/STEP Voltage sweeps cause the output voltage to change from the
present value to a user specified end value at a specified rate of change. A voltage step on the other hand is an instantaneous change in output voltage. The new value will be held for the duration period specified by the user. The final output voltage value of a sweep and a step transient step should be different than the value at the start of the transient step or no change in output value will occur.
FREQ SWEEP/STEP This transient type is similar to a voltage sweep/step except it
affects the frequency. Refer to the previous paragraph.
VOLT/FREQ SWEEP/STEP This transient type combines the previous two types into a single
step. The effect is that of changing the output voltage and frequency simultaneously.
Note: While this transient is programmed as a single transient
MX Series 98
step, two list entries are required to store this information. As such, every VOLT/FREQ SWEEP/STEP used will consume two list entries at a time.
User Manual – Rev AV AMETEK Programmable Power
START/VIEW SEQUENCE This entry allows the user to switch to the transient execution
menu. This menu provides a list of all available transient list steps and their sequence numbers. From this menu, transient list execution can be started.
The same menu can be used to view or edit any available
transient list step or erase a step using the backspace key.
4.2.6.1 VOLT SURGE/SAG sub menu
Figure 4-12: VOLTAGE SURGE/SAG SETUP Screen
The Voltage surge and sag screen shown in Figure 4-12 can be reached from the transient screen as follows:
1. Scroll to the VOLT SURGE/SAG entry using the up and down cursor keys.
2. Press the ENTER key to bring up the VOLT SURGE/SAG screen.
The VOLT SURGE/SAG screen has several data fields. All data fields that are blank to the right of the equal sign must be filled or an error message will occur when trying to leave this screen. The EVENT # is the last data field to be filled. Entering the event data field will cause the display to return to the TRANSIENT screen where a new selection can be made.
The VOLT/SURGE/SAG screen has the following fields: START ø This field will show the start phase angle of the voltage transient
in degrees. Only one start phase angle per transient sequence is allowed. The start phase angle must be in the first transient event in the list. The start phase angle is not valid for DC transients. If no start phase angle is required, this field can be set to RANDOM by pressing the BACKSPACE (<-) key on the decimal keypad.
GO TO VOLT This field will set the voltage level during the transient duration in
volts
DUR SCALE Duration scale default is time in seconds. Use the Shuttle knob
to select CYCLES if desired. Note that durations expressed in cycles may cause rounding errors if the period of the selected frequency setting is not an integer number of mss. Thus, for 50 Hz applications, no rounding errors occur but for 60 Hz, the
16.66¯ ms period will cause a rounding error when converted. The Duration scale selection affects both the DURATION and END DELAY parameters.
DURATION Duration is the time the output voltage level will dwell at the GO
TO VOLT level. The DUR SCALE defines the time scale of this parameter in CYCLES or SECONDS
END VOLT This is the output voltage level at the end of the transient
MX Series 99
EVENT and after a time specified by the DURATION
User Manual – Rev AV AMETEK Programmable Power
END DELAY This is the time delay the voltage level will stay at the END
VOLT level before it proceeds with the next transient event or completes the transient.
FUNCTION [3Pi controller only] This field can be used to select the wave
shape to be used during this step of the transient sequence. Each step can use a different wave shape from the available library of 50 user-defined waveforms or the three standard waveforms. The output wave shape changes upon entry into each step and remains in effect for the duration of the step. The default wave shape is always the SINE (sine wave).
REPEAT This is the number of times the SURGE/SAG transient event will
repeat before it will proceed to the next event or exit the transient program. Note that the number of times the transient event is generated is equal to the REPEAT + 1. Leave this value at zero if only one execution of this event in the list is required.
EVENT # This must be the last item in the transient edit screen. All data
fields must be entered before inserting the EVENT #. The EVENT # takes a value from 1 to 99. The EVENT # defines the order of execution of the transient events in a multiple event transient. It is a good practice to enter spaced EVENT #’s to allow insertion of an EVENT later if needed. (For example, space them by 5.) Entry of a sequence EVENT # number will cause the display to return to the TRANSIENT screen.
