Connection to the output terminals can be made with any of the following: 4mm plugs, spade terminals or wire ends. To minimise voltage drop, the connecting leads to the load should be of an adequate wire gauge and be kept short. The output terminals are duplicated on the rear panel, together with the sense terminals.

The keyboard is located to the left of the output terminals. This consists of 27 keys and a LED indicating the instrument output status. The use of the keyboard to control all instrument functions is discussed in the following sections. To the left of the keyboard is the status display which consists of a 4-digit, 7-segment display and 10 LEDs. Normally the status display will show the output power in Watts when the output is on or will be blank when the output is off; however, other information will appear when selections are made from the keyboard.

The relevant annunciator LED will indicate what the contents of the display represent at any time. Above the keyboard are the main displays and LED indicators which show the conditions of the output.

The displays show the set voltage and set current when the output is off and the voltage at the output terminals and output current when the output is on. To the right of the LED indicators is a continuously rotating control which may be used to make fine adjustments to voltage or current as described later.

The following sections explain in detail the use of the keyboard to control all instrument functions. If an error is encountered during keyboard operation the status display will show Ennn where nnn is a decimal number. The set voltage is normally shown in the top left hand display marked V.

The exception to this is when the output is on and in constant current CI mode. In this case the actual output voltage will be less than the set value and will be shown instead. A new value may now be entered from the numeric keypad. The maximum and minimum values accepted will depend on the particular model, see the specification section for details. When the output is off the set current is shown in the top right hand display marked A. When the output is on and in constant voltage CV mode the output current is shown.

When in constant current CI mode the output current is equal to the set current and this is shown. To set the current press the AMPS key. If a mistake is made during entry press the AMPS key and start again. The Over-Voltage Protection OVP value is not shown in the main display; however, it is active and if at any time the actual value of the output voltage exceeds the set value the OVP circuit will immediately shut down the output, thus avoiding any damage to the circuit under test.

If the. The system will then attempt to recover from the trip and if successful the triP message will be removed and normal operation will resume. If a mistake is made during entry press the OVP key and start again. Delta Volts mode is entered by pressing the DeltaV key. If a mistake is made during entry press the DeltaV key and start again. While in DeltaV mode, i. Turning the knob will increment or decrement the set volts value in 10mV steps irrespective of the set DeltaV value. Delta Amps mode is entered by pressing the Deltal key.

If a mistake is made during entry press the Deltal key and start again. Whilst in Delta Amps mode, i. Turning the knob will increment or decrement the set current value in 10mA steps irrespective of the set Delta Amps value. The instrument contains 25 stores each capable of holding the entire set-up. The stored data is non-volatile and is retained while power is off. The status display will show the number of the last store which was accessed.

This store may be used or a new store number may be entered from the numeric key pad. If the instrument overheads a thermal trip will occur and the main displays will show the triP. The output will then be shut down, i. This condition will persist until the instrument cools to below the trip temperature value, when the output will be usable again. Connection to the front panel output terminals can be made with 4mm plugs, spade terminals or wire ends.

Load wires should also be twisted together to reduce inductance. The output is fully floating and either terminal can be connected to ground or raised by up to V peak above true ground; however, such voltages are hazardous and great care should be taken.

The current limit can be set to limit the continuous output current to levels down to 10mA. However, in common with all precision bench power supplies, a capacitor is connected across the output to maintain stability and good transient response. This capacitor charges to the output voltage, and short circuiting of the output will produce a short current pulse as the capacitor discharges which is independent of the current limit setting.

Remove the two shorting links made between the rear output and sense terminals and connect the sense terminals directly to the load; the power connections may be made from either the front or rear terminals.

To ensure good coupling between the output and sense, the sense wires should be twisted with their corresponding output leads before the output leads are twisted together. The shorting links should be re-made between the rear sense and output terminals when remote sensing is not being used. However, the sense connection is also made internally through a low value resistor and only a small error between the set and actual voltage will result if the links are left disconnected.

The output will be tripped off if the sense wires are wired to the wrong output or if an attempt is made to draw power from the sense wires; the triP message will be shown in both displays. The system will then attempt to recover from the trip and, if successful because the wiring has been corrected , the triP message will be removed and normal operation will resume.

In addition to OVP for forward overvoltage protection, the output is protected from reverse voltages by a diode; the continuous reverse current must not exceed 3 Amps, although transients can be much higher. These instruments are very efficient but nevertheless can generate significant heat at full power. The supplies rely on convection cooling only and it is therefore important that ventilation is never restricted if performance and safety are to be maintained.

If the supplies are mounted in a restricted space, eg. The Manufacturers or their agents overseas will provide repair for any unit developing a fault. Where owners wish to undertake their own maintenance work, this should only be done by skilled personnel in conjunction with the service manual which may be purchased directly from the Manufacturers or their agents overseas. The use of makeshift fuses and the short-circuiting of fuse-holders is prohibited.

To replace the fuse, first disconnect the instrument from the AC supply. Remove the 6 cover securing screws and lift off the cover. Replace the fuse with one of the correct type and refit the cover. Note that the main function of the fuse is to make the instrument safe and limit damage in the event of failure of one of the switching devices.

If a fuse fails it is therefore very likely that the replacement will also blow, because the supply has developed a fault; in such circumstances the instrument will need to be returned to the manufacturer for service. If the PSU requires cleaning use a cloth that is only lightly dampened with water or a mild detergent. Polish the display window with a soft dry cloth. Where operation is identical no distinction is made between the two.

It is therefore only necessary to read the general sections and those sections specific to the interface of interest. The selected interface. Selectable baud rates are , , , , and To select an alternative address enter the required number from the numeric key pad. The range of addresses accepted is 0 to A change of address will become active immediately it is entered from the keyboard and the device will no longer respond to the previous address.

All device operations are performed through a single primary address, no secondary addressing is used. The default address, i.

When the address is changed the new setting is stored in non-volatile ram, and will remain unchanged even while power is off. The RS interface may also be used in a simple non-addressable mode without modification. In this state all keyboard operations are possible. In this state the keyboard is locked out and remote commands only will be processed.

The instrument may be returned to the local state by pressing the LOCAL key; however, the effect of this action will remain only until the instrument is addressed again or receives another character from the interface, when the remote state will once again be entered. The 9-way D-type serial interface connector is located on the instrument rear panel.

The pin connections are as shown below:. Pins 7, 8 and 9 are additionally used when the instrument is connected to the ARC interface. The wiring of the adaptor cable is shown below:. All instruments on the interface must be set to the same baud rate and all must be powered on, otherwise instruments further down the daisy chain will not receive any data or commands. The ARC standard for the other interface parameters is as follows; in these power supplies and most other ARC instruments they are fixed.

No distinction is made between upper and lower case characters in command mnemonics and they may be freely mixed. All instruments intended for use on the ARC bus use the following set of interface control codes. Codes between 00H and 1FH which are not listed here as having a particular meaning are reserved for future use and will be ignored. When an instrument is first powered on it will automatically enter the NonAddressable mode.

In this mode the instrument is not addressable and will not respond to any address commands. This allows the instrument to function as a normal RS controllable device. The controller and instrument can now freely use all 8 bit codes and binary blocks but all interface control codes are ignored.

To return to addressable mode the instrument must be powered off. This will then enable all instruments connected to the ARC bus to respond to all interface control codes. To return to Non-Addressable mode the Lock Non-Addressable mode control code must be sent which will disable addressable mode until the instruments are powered off.

Before an instrument is sent a command it must be addressed to listen by sending the Listen Address control code, 12H LAD , followed by a single character which has the lower 5 bits corresponding to the unique address of the required instrument, e. Once addressed to listen the instrument will read and act upon any commands sent until the listen mode is cancelled.

Because of the asynchronous nature of the interface it is necessary for the controller to be informed that an instrument has accepted the listen address sequence and is ready to receive commands. The controller should time-out and try again if no ACK is received within 5 seconds. Listen mode will be cancelled by any of the following interface control codes being received:. Before a response can be read from an instrument it must be addressed to talk by sending the Talk Address control code, 14H TAD followed by a single character which has the lower 5 bits corresponding to the unique address of the required instrument, as for the listen address control code above.

Once addressed to talk the instrument will send the response message it has available, if any, and then exit the talk addressed state. Only one response message will be sent each time the instrument is addressed to talk. Talk mode will be cancelled by any of the following interface control codes being received:. Talk mode will also be cancelled when the instrument has completed sending a response message or has nothing to say.

The interface code 0DH CR may be used as required to aid the formatting of commands; it will be ignored by all instruments. Most instruments will terminate responses with CR followed by LF. The interface code 13H XOFF may be sent at any time by a listener instrument or controller to suspend the output of a talker.

The listener must send 11H XON before the talker will resume sending. This is the only form of handshake control supported by ARC. The IEEE This will cause the Query Error bit to be set in the Standard Event Status Register, a value of 1 to be placed in the Query Error Register and the response formatter to be reset thus clearing the output queue.

If the response formatter is waiting to send a response message and the input queue becomes full then the instrument enters the DEADLOCK state and an error is generated. This will cause the Query Error bit to be set in the Standard Event Status Register, a value of 2 to be placed in the Query Error Register and the response formatter to be reset thus clearing the output queue.

The power supplies offer complete parallel poll capabilities. The instrument must also be configured so that the value of ist can be returned to the controller during a parallel poll operation. The bits in the PPE command are shown below:.

To return the RQS bit bit 6 of the Status Byte Register as a 1 when true and a 0 when false in bit position 1 in response to a parallel poll operation send the following commands. During parallel poll response the DIO interface lines are resistively terminated passive termination. Most instrument settings are stored in non-volatile ram and will remain unchanged while power is off. The following instrument status values are set at power on:. The standby state will be set and the instrument will be in local with the keyboard active.

A complete self-test will be performed just after power up and this will determine the values in the Failed Output Register and the state of the FLT bit in the Status Byte Register. Due to the non-volatile storage the power on settings are essentially modified by any command, local or remote, which changes any value not listed above. This section describes the complete status model of the instrument.

The parser is reset and parsing continues at the next byte in the input stream. Operation Time-out Error. Set when an attempt is made to set an output to a specific. Query Error. Set when a query error occurs. The appropriate error number will be. These two registers are implemented as an addition to the IEEE std. Bit 2 - Set when an output trip has occurred. Bit 1 - Set when output enters voltage limit. Bit 0 - Set when output enters current limit.

The Event Status Bit. This bit is set if any bits set in the Standard Event Status. The Limit status bit.
