Safety Precautions

The following safety precautions should be observed before using this product and any associated instrumentation. Although some in­struments and accessories would normally be used with non-haz­ardous voltages, there are situations where hazardous conditions may be present.
This product is intended for use by qualified personnel who recog­nize shock hazards and are familiar with the safety precautions re­quired to avoid possible injury. Read the operating information carefully before using the product.
The types of product users are: Responsible body is the individual or group responsible for the use
and maintenance of equipment, for ensuring that the equipment is operated within its specifications and operating limits, and for en­suring that operators are adequately trained.
Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of the instru­ment. They must be protected from electri c s hock and contact with hazardous live circuits.
Maintenance personnel perform routine procedures on the product to keep it operating, for example, setting the line voltage or replac­ing consumable materials. Maintenance procedures are described in the manual. The procedures explicitly state if the operator may per­form them. Otherwise, they should be performed only by service personnel.
Service personnel are trained to work on live circuits, and perform safe installations and repairs of products. Only properly trained ser­vice personnel may perform installation and service procedures.
Keithley products are designed for use with electrical signals that are rated Installation Category I and Installation Category II, as de­scribed in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most measurement, control, and data I/O sig­nals are Installation Category I and must not be directly connected to mains voltage or to voltage sources with high transient over­voltages. Installation Category II connections require protection for high transient over-voltages often associated with local AC mains connections. The user should assume all measurement, con­trol, and data I/O connections are for connection to Category I sources unless otherwise marked or described in the Manual.
Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or test fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than 30V RMS,
42.4V peak, or 60VDC are present. A good safety practice is to ex-
pect that hazardous voltage is present in any unknown circuit before measuring.
Users of this product must be protected from electric shock at all times. The responsible body must ensure that users are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential human contact. Product users in these circumstances must be trained to protect themselves from the risk of electric shock. If the circuit is capable of operating at or above 1000 volts, no conductive part of the circuit may be
exposed.
Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance limited sources. NEVER connect switching cards directly to AC mains. When con­necting sources to switching cards, install protective devices to lim­it fault current and voltage to the card.
Before operating an instrument, make sure the line cord is connect­ed to a properly grounded power receptacle. Inspect the connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.
When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main input power dis­connect device must be provided, in close proximity to the equip­ment and within easy reach of the operator.
For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the circuit under test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting cables or jump­ers, installing or removing switching cards, or making internal changes, such as installing or removing jumpers.
Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the voltage being measured.
The instrument and accessories must be us ed in accordanc e with its specifications and operating instructions or the safety of the equip­ment may be impaired.
WARNING
Do not exceed the maximum signal levels of the instruments and accessories, as defined in the specifications and operating informa­tion, and as shown on the instrument or test fixture panels, or switching card.
When fuses are used in a product, replace with same type and rating for continued protection against fire hazard.
Chassis connections must only be used as shield connections for measuring circuits, NOT as safety earth ground connections.
If you are using a test fixture, keep the lid closed while power is ap­plied to the device under test. Safe operation requires the use of a lid interlock.
If a screw is present, connect it to safety earth ground using the wire recommended in the user documentation.
!
The symbol indicates that the user should refer to the operat­ing instructions located in the manual.
The symbol indicates that voltage levels greater than 30V RMS, 42.4V peak, or 60VDC are present. Use standard safety pre­cautions to avoid personal contact with these voltages.
The WARNING heading in a manual explains dangers that might result in personal injury or death. Always read the associated infor­mation very carefully before performing the indicated procedure.

Before performing any maintenance, disconnect the line cord and all test cables.
To maintain protection from electric shock and fire, replacement components in mains circuits, including the power transformer , test leads, and input jacks, must be purchased from Keithley Instru­ments. Standard fuses, with applicable national safety approvals, may be used if the rating and type are the same. Other components that are not safety related may be purchased from other suppliers as long as they are equivalent to the original component. (Note that se­lected parts should be purchased only through Keithley Instruments to maintain accuracy and functionality of the product.) If you are unsure about the applicability of a replacement component, call a Keithley Instruments office for information.

2-2 Operation S470 User’s manual

Operation

The S470 system uses the same operating information as an S400 system. This section contains information on power controller operation and is arranged as follows:
Control locations — Details information on the front panel controls and on the power distri-
bution unit.
Grounding (protective earthing) — Describes proper groundin g at a site’s power receptacle.
System operation — Provides procedures for placing system in operation, restarting after a
loss of line voltage, and turning system off.
VME controls — Details VME controls and indicators.
Control locations
Controls are located on the front panel of the system (Figure 2-1).
Grounding (protective earthing)
The power cord connects the power controller to a protective earth ground. The safety ground wire location (close to the phase and neutral wires) ensures a low impedance connection between the power controller and a properly grounded outlet. The safety ground connects directly to the chassis inside the power controller.
Ground the power controller to a properly grounded receptacle before operation. For effective protection, a low impedance connection must be provided to the outlet (installed within your facility). Wiring installed in accordance with local electrical codes ensures that this requirement is met.
WARNING The power controller must be grounded to a properly grounded
receptacle before operation. Failure to properly ground the power controller may result in severe injury or death.

System operation

This section contains procedures for system operation. Perform these procedures only after becoming familiar with the operation of the power distribution unit.
Operation procedure
Use the following procedure to place the system in operation:
1. Make sure power cord is plugged into a properly grounded outlet and all DUT connections have been removed.
2. Press SYSTEM POWER to START (Figure 2-1).
The momentary switch will revert to the ON position when pressure is released.
When SYSTEM POWER is in the ON position after being in the START position, the
switch is illuminated, which indicates power is applied to the system including the cabi­net fans.
3. Press INSTRUMENT POWER ON.
When INSTRUMENT POWER ON is pressed, the pushbutton will illuminate indicating
power is applied to the relay matrix and system instruments.
DUT connections can be made, and instrument power can only be turned on after system
power is on.
4. To start the software after booting system, refer to the S400UX Workstation User’s manual (UNIX), document number 4615-901-00.
Restarting after a loss of line voltage
The emergency shutdown circuit automatically turns off all power to the system if line power is interrupted. This trips the EMO circuit. After the EMO circuit is tripped, it must be reset before power can be applied to the system and the instruments. Call maintenance personnel to reset the EMO circuit. Then start the system using the operation procedure.
Turning system off
Certain components can be turned off while leaving others on (computers, cabinet fans, etc.). In addition, the EMERGENCY OFF pushbutton (one switch) turns off all components connected to the power controller.
The two ways to turn off the system are as follows:
Emergency turn off.
Turning system power to STANDBY.
Emergency turn off
Press the EMERGENCY OFF button on the front panel of the system. Emergency off can also be accomplished by pressing an optional remote emergency off button.
2-4 Operation S470 User’s manual
NOTE To start after an emergency turn off, use the procedure in the paragraph
"Restarting after a loss of line voltage".
Turning off the complete system
Press the INSTRUMENT POWER OFF button.
Press the SYSTEM POWER button to the STANDBY position.
Optional remote EMO Emergency Off switches
Optional remote EMO Emergency Off switches are available for the S400 system. The remote EMO switches function the same as the EMO switch located on the front panel of th e system. The switches are a normally closed, momentary action type switch, connected in series with the front panel EMO switch. Pressing any switch disconnects the system from line power which contains all voltages within the power controller chassis.
Two safety features are built into each remote EMO switch. The emergency OFF switches are connected to the low voltage (24VAC) control voltage. This prevents line voltage from being connected to the remote switches. Voltage to the remote emergency OFF switches is discon­nected after an emergency off switch is pressed.

VME controls

The front panel contains the VME RUN indicator and the VME RESET switch. The VME RUN indicator is illuminated when the instrument controller in the instrument card file (Model 9000- ICF) is operating. Reset the instrument controller by pressing the RESET switch.
NOTE The operating software for the instrument controller must be down-
loaded to the applications processor if the instrument controller is r eset. The instrument controller may also be reset using the local reset button on the instrument controller itself.
