SAFETY SUMMARY
This power source contains high voltage and current circuits, which are potentially lethal.
Because of its size and weight, mechanical stability must be ensured. The following
safety guidelines must be followed when operating or servicing this equipment. These
guidelines are not a substitute for vigilance and common sense. California Instruments
assumes no liability for the customer’s failure to comply with these requirements. If the
power source is used in a manner not specified by California Instruments, the protection
provided by the equipment may be impaired.
BEFORE APPLYING POWER
1. Verify the correct three phase input voltage is applied to the unit. Input ratings are shown
on the model and serial number tag located at the rear of the unit.
2. The chassis and cabinet of this power source must be grounded to minimize shock hazard.
A chassis ground is provided at the input terminal block. This is located in the front of the
cabinet on the lower left hand side. The lower front cover panel must be removed to
access the line input and ground connections. The chassis ground must be connected to
an electrical ground through an insulated wire of sufficient gauge.
FUSES
Use only fuses of the specified current, voltage, and protection speed (slow blow, normal blow,
fast blow) rating. Do not short out the fuse holder or use a repaired fuse.
DO NOT OPERATE IN A VOLATILE ATMOSPHERE
Do not operate the power source in the presence of flammable gases or fumes.
DO NOT TOUCH ENERGIZED CIRCUITS
Disconnect the power cable before servicing this equipment. Even with the power cable
disconnected, high voltage can still exist on some circuits. Discharge these voltages before
servicing. Only qualified service personnel may remove covers, replace components or make
adjustments.
DO NOT SERVICE ALONE
Do not remove covers, replace components, or make adjustments unless another person, who
can administer first aid, is present.
DO NOT EXCEED INPUT RATINGS
Do not exceed the rated input voltage or frequency. Additional hazards may be introduced
because of component failure or improper operation.
DO NOT MODIFY INSTRUMENT OR SUBSTITUTE PARTS
Do not modify this instrument or substitute any parts. Additional hazards may be introduced
because of component failure or improper operation.
MOVING THE POWER SOURCE
When moving the power source, observe the following:
1. Remove all AC power to unit.
2. Do not attempt to lift by hand. Raise the levelers and push the unit using two people to
prevent injury or use forklift equipment with a qualified operator.
ALLOW CAPACITORS TO DISCHARGE
Capacitors in the power source may hold a hazardous electrical charge even if the power source
has been disconnected from the mains supply. Allow capacitors to discharge to a safe voltage
before servicing internal circuits or touching exposed pins of the mains supply connectors.

User Manual – Rev B FCS Series II
1. Introduction
This instruction manual (P/N 5000-967) contains information on the installation, operation,
calibration and maintenance of the FCS Series II AC power sources.
FCS Series II models are different from the original FCS Series in the following areas:
• New higher performance controller with arbitrary waveform capability is used.
• Standard RS232 and USB interfaces have been added in addition to GPIB.
• Optional Ethernet LAN interface is available. (Option –LAN).
• The front panel keyboard display is more user friendly with full decimal keypad for data
entry.
• Number of available output voltage range options has been reduced to 135/270
(standard), 156/312 or 200/400.
1.1 General Description
The FCS Series II AC Power Source is a high efficiency, cabinet AC Power Source/Analyzer
combination that provides a precise output and advanced measurements. Standard output
voltage ranges are 135 Vac and 270 Vac RMS. The FCS II Series is available in either single (-
1) or three-phase (-3) mode. Three phase units offer an optional single-phase mode for both
modes of operation.
For power levels above 18 KVA, two or more FCS series units can be combined using the
system interface in a parallel mode of operation. These multi chassis systems consist of one
master unit with controller and one or two auxiliary units without controllers. Only the master unit
has a front panel keyboard and display.
Read the installation instructions carefully before attempting to install and operate the FCS
Series II power systems.

2.5 Special Features
Controller Features
Mode: Switches between 1 and 3 phase outputs.
Parallel Operation: FCS36 and FCS54 systems use two or three chassis in parallel
operation. The two or three chassis must be connected using the system
interface cable supplied with the system.
Controller: Programmable controller front panel assembly.
Output Relay: Standard output relay feature to isolate power source from the load.
Output On/Off: The output relay can be used to quickly disconnect the load. A yellow
status indicator displays the status of the output relay. Relay is either
through front panel button or using Remote Inhibit input signal.
External Trigger Output
or Function Strobe
An external TTL output is available which may be used to trigger other
equipment. The TTL output can be controlled by the transient
programming system. This requires the trigger mode to be set to EXT
(factory default). This can only be done over the bus using the
OUTP:TTLT:MODE TRIG command.
It can also be configured to generate an output pulse any time the
voltage, frequency, current limit or phase programming is updated. This
requires the trigger mode to be set to FSTR. This can only be done over
the bus using the OUTP:TTLT:MODE FSTR command. This mode is
compatible with the CI FCS Series I.
The Trigger Output / function strobe is an active low TTL signal with a
duration of no less than 400 usec.
Clock and Lock Mode Enables two or more independent FCS II power systems to be phase
synchronized to each other. One system (-LKM) acts as the master, the
other(s) (-LKS) as auxiliaries. The –LKS units are synced to the –LKM
unit. Refer to section 3.9 for details on Clock and Lock mode.
Trigger Input A TTL input signal may be used as an external trigger source for output
changes programmed on the AC power source transient system. This
requires the trigger source to be set to EXT. This can only be done over
the bus.
