Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your
particular application.
WARNIN
WARNIN
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.
Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above
(below) chassis ground.
The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.

About This Manual
This operating manual is for the internal Multichannel Interface (GPIB-M), a
microprocessor-controlled option card for your DC output power supply. This
manual provides you with descriptions and specifications, user options, and
configuration instructions, in addition to a command set which enables you to
manage the power supply from an external source. Error messages and calibration
procedures are also included.
This manual is designed for the user who is familiar with basic electrical theory
especially as it applies to the operation of power supplies. This implies a recognition
of Constant Voltage and Constant Current operation modes and the control of input
and output power, as well as the observance of safe techniques while effecting supply
or pin connections and any changes in switch settings. The user should also have
experience with a computer-based communications software package.
Refer to your power supply manual for installation, configuration, and operating
procedures for your power supply.

Operating Manual for Multichannel Functionality (GPIB-M)
Section 1. Features and Specifications
Description
The internal GPIB-M interface card allows you to operate your power supply from
a computer controller via the IEEE-488 communications bus.
The GPIB-M interface allows complete remote programming of your power supply,
including status reporting, settings query, and service request generation with
user-designated conditions. Both the voltage and current output are precisely
programmed directly in volts and amps with 16-bit resolution. Additionally, the
16-bit readbacks measure the actual power supply output. The programming
command set is easy to use and includes software calibration commands. The
interface card comes with several protection features such as programmable over
and under voltage protection, and soft limits.
Multichannel addressing via CANbus allows up to 50 power supplies to be
controlled from one GPIB address. This manual covers operation of both the
GPIB-M and CAN-only interface cards.
Features and Functions
Features • 16-bit programming and readback of voltage and current
• Programmable soft limits for voltage and current
• LED status signals: remote operation, serv ice request and shutdown; (XFR and
XHR only) error, addressed, over voltage protection, auxiliary status bits
• Software calibration
• Automatic voltage/current mode crossover
• Shutdown or warning for over- and under-programmed trip points
• Programmable auxiliary status lines for monitoring power supply conditions
• Remote interlock and trigger lines
• Selectable standby, programmed sequence and other power-on defaults
• Active current sharing with parallel connected units for higher power
requirements
• CANbus communications link for multichannel addressing, and master/slave
current sharing
• Extensive SCPI command set for control and status monitoring

Introduction
To use this product, you must have the following equipment:
• a compatible model of DC output power supply
• IEEE-488 connector and cable
• computer with an IEEE-488 interface card
• Computer-based communications software package
• parallel CANbus cables (to connect power supply for multichannel operation)
The GPIB
Your local distributor or service center can also install the interface, especial ly for
use in a previously-purchased supply already on site. The interface card will be
calibrated and configured with default settings. Y ou will need to configure the supply
for your system using the “Basic Setup Procedure” on page 31. Refer also to
Figure 2.1, pg. 26, Figure 2.2, pg. 27 and Figure 2.3, pg. 27 for drawings of the front
panels. The interface subplate is different for each product. Please check Figure 2.4
to Figure 2.7.
Initial Inspection
On first receiving your unit, perform a quick inspection.
• Ensure each package contains a power supply with its GPIB interface board
• Inspect the unit for any signs of physical damage such as scratches, cracks, or
• Check the printed circuit board and components if you suspect internal damage.

CAUTION
If you remove the unit's cover, use proper static control techniques to avoid damage
to static-sensitive components on the printed circuit board.

CANbus cable and a terminator are also supplied with each GPIB-M or
CAN-only interface. Any additional parts shipped with the power supply will be
identified in the supply's documentation.

If the unit is damaged, save all packing materials and notify the carrier immediately.
For additional information, please see the section titled, “Returning Power Supplies
to the Manufacturer” in the manual shipped with your complete unit.

Remote Programming LEDs:
Local Switch (LOCAL)Remote LED (REM)
Address LED (ADR)
Indicates that the master controller is ad dressing the unit.
Service Request LED (SRQ)
Comes on at power up if the PON SRQ is set to on.
Error LED (ERR)
Indicates when a programming error has occurred. You
can clear the ERR LED with an error query command.
Fault LED (FLT )
Used to indicate AUX B status is TRUE.
Polarity LED (POL)
Used to indicate AUX A status is TRUE.
