SAFETY INSTRUCTIONS

This chapter contains important safety instructions that you must follow during operation and storage. Read the following before any operation to insure your safety and to keep the instrument in the best possible condition.

Safety Symbols

These safety symbols may appear in this manual or on the instrument.

SAFETY INSTRUCTIONS

Do not dispose electronic equipment as unsorted municipal waste. Please use a separate collection facility or contact the supplier from which this instrument was purchased.

General Guideline

CAUTION

 Do not place any heavy object on the PSU.  Avoid severe impact or rough handling that

leads to damaging the PSU.

 Do not discharge static electricity to the PSU.  Use only mating connectors, not bare wires, for

the terminals.

 Do not block the cooling fan opening.  Do not disassemble the PSU unless you are

qualified.

WARNING

 AC Input voltage range: 85Vac~265Vac  Frequency: 47Hz to 63Hz  To avoid electrical shock connect the protective

grounding conductor of the AC power cord to an earth ground.

Safety Guidelines

PSU Series Programming Manual

Cleaning the PSU

 Disconnect the power cord before cleaning.  Use a soft cloth dampened in a solution of mild

detergent and water. Do not spray any liquid.

 Do not use chemicals containing harsh material

such as benzene, toluene, xylene, and acetone.

Operation Environment

 Location: Indoor, no direct sunlight, dust free,

almost non-conductive pollution (Note below)

 Relative Humidity: 20%~ 85% (no condensation)  Altitude: < 2000m  Temperature: 0°C to 50°C

(Pollution Degree) EN61010-1:2010 and EN61010-2-030 specifies the pollution degrees and their requirements as follows. The PSU falls under degree 2.

Pollution refers to “addition of foreign matter, solid, liquid, or gaseous (ionized gases), that may produce a reduction of dielectric strength or surface resistivity”.

 Pollution degree 1: No pollution or only dry, non-conductive

pollution occurs. The pollution has no influence.

 Pollution degree 2: Normally only non-conductive pollution

occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.

 Pollution degree 3: Conductive pollution occurs, or dry, non-

conductive pollution occurs which becomes conductive due to condensation which is expected. In such conditions, equipment is normally protected against exposure to direct sunlight, precipitation, and full wind pressure, but neither temperature nor humidity is controlled.

Storage environment

 Location: Indoor  Temperature: -25°C to 70°C  Relative Humidity: ≤90%(no condensation)

Disposal

Do not dispose this instrument as unsorted municipal waste. Please use a separate collection facility or contact the supplier from which this instrument was purchased. Please make sure discarded electrical waste is properly recycled to reduce environmental impact.

Power cord for the United Kingdom

When using the power supply in the United Kingdom, make sure the power cord meets the following safety instructions.

NOTE: This lead/appliance must only be wired by competent persons

WARNING: THIS APPLIANCE MUST BE EARTHED IMPORTANT: The wires in this lead are coloured in accordance with the following code:

As the colours of the wires in main leads may not correspond with the coloured marking identified in your plug/appliance, proceed as follows:

The wire which is coloured Green & Yellow must be connected to the Earth terminal marked with either the letter E, the earth symbol

or coloured Green/Green & Yellow.

The wire which is coloured Blue must be connected to the terminal which is marked with the letter N or coloured Blue or Black.

The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red.

If in doubt, consult the instructions provided with the equipment or contact the supplier.

This cable/appliance should be protected by a suitably rated and approved HBC mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, a cable of 0.75mm2 should be protected by a 3A or 5A fuse. Larger conductors would normally require 13A types, depending on the connection method used.

Any exposed wiring from a cable, plug or connection that is engaged in a live socket is extremely hazardous. If a cable or plug is deemed hazardous, turn off the mains power and remove the cable, any fuses and fuse assemblies. All hazardous wiring must be immediately destroyed and replaced in accordance to the above standard.

Operation

1. Check the F-89 (System version and build date)

settings first on all units. The two parameters O and P (Option Module) must be the same on all units before any multiple unit connection can be established.

Example: F-89 O:00, P:01.

2. Connect the first unit’s IN port to a PC via

RS232 or RS485 serial cable.

 Use the serial cables supplied in the PSU-

Multiple Unit Connection

The PSU power supplies can have up to 31 units daisy chained together using the 8 pin connectors (IN OUT ports) on the rear panel. The first unit (master) in the chain is remotely connected to a PC using RS232 or RS485 (Legacy Multi-Drop mode), or USB, GPIB or LAN (Multi-Drop mode). Each subsequent unit (slave) is daisy chained to the next using a RS485 local bus. The OUT port of the first unit must be connected to intermediate connector and the OUT port of the last unit must be connected to end terminal connector.

There are two modes for controlling multiple units. In the first mode (Legacy Multi-Drop mode), the PC is only allowed to use RS232 or RS485 to connect to the first device, and all UART parameters must be executed in this mode Configuration. The remote command supports the SCPI commands or TDK GENESYS legacy commands.

In the second mode (Multi-Drop mode), the PC is allowed to connect to the first unit using USB-CDC/GPIB/LAN. In this mode, you only need to specify the Multi-Drop parameter. Remote commands only support SCPI commands.

For these two modes, each unit is assigned a unique address, which can then be controlled independently of the host PC.

Command Structure

SCPI commands follow a tree-like structure, organized into nodes. Each level of the command tree is a node. Each keyword in a SCPI command represents each node in the command tree. Each keyword (node) of a SCPI command is separated by a colon (:).

For example, the diagram below shows an SCPI sub-structure and a command example.

MEASure

SCALar

POWer

VOLTage

CURRent

MEASure:SCALar:CURRent:DC?

Command types

There are a number of different instrument commands and queries. A command sends instructions or data to the unit and a query receives data or status information from the unit.

Command types

Simple

A single command with/without a parameter

Example

*IDN?

Command Syntax

REMOTE CONTROL

Query

A query is a simple or compound command followed by a question mark (?). A parameter (data) is returned.

Example

meas:curr:dc?

Compound

Two or more commands on the same command line. Compound commands are separated with either a semi-colon (;) or a semicolon and a colon (;:).

A semi-colon is used to join two related commands, with the caveat that the last command must begin at the last node of the first command.

A semi-colon and colon are used to combine two commands from different nodes.

Example

meas:volt:dc?;:meas:curr:dc?

Command Forms

Commands and queries have two different forms, long and short. The command syntax is written with the short form of the command in capitals and the remainder (long form) in lower case.

The commands can be written in capitals or lowercase, just so long as the short or long forms are complete. An incomplete command will not be recognized.

Below are examples of correctly written commands.

PSU Series Programming Manual

Long form

STATus:OPERation:NTRansition? STATUS:OPERATION:NTRANSITION? status:operation:ntransition?

Short form

STAT:OPER:NTR? stat:oper:ntr?

Square Brackets

Commands that contain square brackets indicate that the contents are optional. The function of the command is the same with or without the square bracketed items, as shown below.

Both “DISPlay:MENU[:NAME]?” and “DISPlay:MENU?” are both valid forms.
