1Introduction and specifications
1.1 General introduction
The SYSTEM 7000 is a DC constant current output Power Supplies designed for applications
requiring very high stability and low noise combined with reliability and ease of operation.
The SYSTEM 7000 is aimed at correction magnets in ion beam applications. It is the result of
an intensive development effort at Danfysik based on twenty years of experience in delivering
precision DC Power supplies to industrial and research laboratory users around the world.
Up to five SYSTEM 7000 units can be connected in a parallel Master/slave configuration. All
analogue signals are summed in the master unit. The master unit monitors and controls the
parallel connected slave units.
•Current stability options of 100 ppm classes
•Power outputs up to 1.5 kW per unit and 7.5kW with 5 units in parallel
•Output current (maximum) up to 20 A Bipolar per unit and 100 A with 5 units in parallel
•Local controlled or Remote controlled through a RS232, RS422 or RS485 serial interface
line.

1.3 Warranty and warranty repair
DANFYSIK A/S warrants that the products manufactured by us will be free from defects in
material and workmanship that adversely would affect the normal functioning of the unit, for a
period of 18 months from the date of shipment or 12 months from the date of installation
whichever occurs first.
The exemptions to this are:
a) Parts not manufactured by DANFYSIK A/S which are covered by the original
equipment manufacturer's warranty.
b) Repair work, which is warranted for six (6) months from the date of shipment from
the DANFYSIK works.
DANFYSIK A/S will repair or replace either on site or at the factory, at option, any equipment
which proves to be defective within its warranty period.
In the case of warranty, DANFYSIK A/S will pay or reimburse lowest freight rate (two-way) of
any item returned to DANFYSIK or our designated agent/representative, provided that prior
written authorisation for such return has been given by DANFYSIK A/S.
This warranty shall not apply to any equipment, which has become defective or unworkable due to
mishandling, improper maintenance, incorrect use, radiation damage or any other circumstance not
generally acceptable for equipment of a similar type.
On standard products, DANFYSIK A/S reserves the right to make changes in design without
incurring any obligation to modify previously manufactured units.
The foregoing is the full extent of this warranty, and no other warranty is expressed or implied. In
no event shall Danfysik be liable for special damages arising from the delivery, late delivery or use
of the equipment.
If any fault develops, the following steps should be taken.
Notify DANFYSIK A/S, giving full details of the problems, and include Model-Type and Serial
number.
On receipt of these information, DANFYSIK A/S will give you either service information or
instructions for shipping.
All shipments of DANFYSIK equipment should be made according to our instructions and shipped
in the original or a similar container.
For smaller parts a carton will be sufficient, if the parts are wrapped in plastic or paper and
surrounded with at least 10 centimetres of shock-absorbing material.

* If the External Interlock 1 is unused, then short-circuit the terminals.
* If the External Interlock 2 is unused, then short-circuit the terminals.
* If the External Interlock 3 is unused, then short-circuit the terminals.
* If the External Interlock 4 is unused, then short-circuit the terminals.
2.5 Master configuration (No parallel units connected)
•The Master/ Slave slide switch, located in the back of the cabinet, must be set to Master.
•Connect Analogue or Digital interface remote control cable if applicable.
•Connect the termination plug in the “Parallel unit to slave” DB25 male connector located on
the back of the cabinet. (Pin 1 & 2 shorted).

DANFYSIK A/S - DK 4040 JYLLINGE - DENMARK.
2.6 Master/ Slave configuration (two or more unit in parallel)
•The Master / Slave slide switch located on the back of the supply must be placed in Master
position for the master unit and in slave position for all the other units. Only one SYSTEM
7000 must be configured as master.
•Connect the “Parallel unit” interface cable between the “Parallel unit to slave” DB25 male
plug of the first unit (normal master) to the “Parallel unit to master” DB25 female plug of
the next unit and so on in a daisy chain. The first unit must have the termination plug
connected to the “Parallel unit to master” and the last unit must have the termination plug
connected to the “Parallel unit to slave”.
•Not used external interlocks must be short-circuited.
