INTRODUCTION
HP 5890 SERIES II GAS CHROMATOGRAPH
This section is intended to help the technician isolate problems to aspecific component or compo-
nents. The HP 5890 Series II may be found in many different configurations, with varying component
options. This complicates the process of providing detailed troubleshooting procedures for even gener-
al problems. But, by using the general troubleshooting techniques presented here, along with the func-
tional diagrams found at the end of this section, successful results should be achieved.
There are five inlet options and six detector options which may be encountered when servicing an HP
5890 Series II Gas Chromatograph, as well as awide variety of flow and pressure control components.
All of these common inlet and detector components are represented by the functional diagrams at the
end of this section. When troubleshooting inlets, detectors, and/or the flow/pressure systems, fold out
the page corresponding to the employed detector,while leaving the book open to the page corre-
sponding to the employed inlet. Maintenance procedures for most of the components are given in the
following sections. Procedures are supplied to remove, replace, and/or clean various subassemblies,
based on the current maintenance philosophy,i. e., to allow replacement of the lowest level compo-
nents applicable for aparticular item.
Specific part numbers are not given in this portion of the service manual. For all replacement part num-
bers, refer to the IPB portion of this document.
This document is not meant to provide instruction for first time installation of any of the options dis-
cussed. The add-on sheets, which accompany the various options, exist for just this purpose, and
should be referenced when performing afirst time installation.

Electronic Troubleshooting
INTRODUCTION
This section is intended to aid the operator and service engineer in the troubleshooting process, i.e., of
going from symptom to cause. It has been subdivided into four subsections by type of symptom.
Part Acovers the most obvious indications of problems. The instrument apparently (generally when
first turned on) doesn’twork at all. (NON-FUNCTIONING INSTRUMENT)
Part Bincludes the symptoms that can appear as avisual indication or message on the front of the
keyboard/display module. These messages are aresult of the instrument’sextensive automonitoring
system. (AUTOMONITOR MESSAGES)
Part Cdiscusses the visual information that the operator can instigate and use as part of the trouble-
shooting process. These visual indications are normally not available unless specifically requested by
the operator.(OPERATOR INSTIGATED INDICATIONS)
Part Dcontains symptoms (other than those that appear on the visual display) that indicate apossible
problem. Typically,these types of symptoms can be associated with aspecific functional area of the
instrument. (FUNCTIONAL SYMPTOMS )
Electrical Safety Precautions
In all nonelectrically oriented sections of this manual, the standard Hazardous Voltage Warning strongly
recommends turning off all of the power to the instrument. However,this section, as well as most of
Service Section, requires that some electrical measurements be made on active (energized) circuits.
MEASUREMENTS AND/OR TESTS THATNEED TO BE MADE ON ELECTRICALLY
ENERGIZED PORTIONS OF THE INSTRUMENT SHOULD BE PERFORMED ONLYBY
SERVICE-TRAINED PERSONNEL WHO ARE AWARE OF ALL INVOLVED HAZARDS.
The Service Section of this manual contains proper step by step procedures for replacing electronic
boards and other major assemblies. These procedures include instructions that should be followed for
both personnel and instrument welfare.
`The following steps require protection against ESD (Electro-Static Discharge).
Use agrounded wrist strap (part no. 9300-0969 -large, or 9300-0970 -small)
connected to asuitable ground. Failure to heed this caution may result in
damage to the instrument.
`When storing or in between handling of PCBs (Printed Circuit Boards), always
place them in static control envelopes or enclosures.
Recommended Test Equipment
The only piece of test equipment required to troubleshoot the instrument is agood, volt/ohmmeter.

SVC 1-3
PART ANON-FUNCTIONING INSTRUMENT
Atotally non-functioning or DEAD instrument is one that apparently isn’tworking at all. It has no visual
indications (i.e., messages) on its front panel and produces no noise or heat.
The most obvious cause for such aproblem is that line power is not reaching the instrument or that the
instrument is not turned on. First check that the Line Power Switch is ON. Then verify that the instru-
ment power cord is plugged into aproper receptacle. If neither of these acts restore the instrument to
operation, suspect that there may be aproblem with the receptacle or the power being supplied to it.
This type of situation generally requires that a local electrical maintenance person be informed to reme-
dy the problem. However,on the rare occasion that power is being provided, but the instrument is not
working, the problem area must be isolated by tests and measurements on the instrument.
MEASUREMENTS AND/OR TESTS THATNEED TO BE MADE ON ELECTRICALLY
ENERGIZED PORTIONS OF THE INSTRUMENT SHOULD BE PERFORMED ONLYBY
SERVICE-TRAINED PERSONNEL WHO ARE AWARE OF ALL INVOLVED HAZARDS.
Any one of several problems internal to the instrument can cause the non-functioning symptom. Since
the instrument operates under processor control, afaulty component in the CPU or Clock sections of
the Main Board may be the source of the problem. More commonly,aproblem in the instrument’spow-
er supply would be the most likely to cause this type of problem.
Two bits of information, plus the use of IPB, should enable service-trained personnel to isolate and
then correct the cause of the problem if it is power related. The first important bit of information is about
the fuses that are internal to the instrument. The second bit is the normal sequence of events that oc-
curs as the instrument is energized (Power On Sequence).
Fuse Information
Fuses have been installed at several locations within the instrument for the protection of major power
circuits. They are designed to open as quickly as possible to prevent damage to other components
within the circuit. Occasionally,an opened fuse may have been caused by ashort onetime surge; how-
ever,it is far more common that a component within the protected circuit has failed. When an open fuse
is noticed, replace it once. If the replacement blows, suspect acomponent failure.
Fuses are located on the AC Power Board and on the Main Board. The AC Power Board fuses protect
the two high-power circuits. One fuse, (F1) or two in asplit phase circuit (F3 &F4), protects the col-
umn oven heater and fan. Another fuse (F2) or two in asplit phase circuit (F1 &F2) protects the main
power transformer.(Refer to Section 8of the IPB portion of this document for power supply PCB infor-
mation. Refer to Section 9of the IPB portion of this document for main PCB information.)
The three secondary voltages of the main power transformer are protected with fuses located on the
Main Board. F3 protects the 120 VAC secondary which ultimately provides heater power for all of the
zones. F4 and F5 protect the 40 VAC secondary which ultimately provides all of the DC supply voltages
(+5, +10, +15, -15, +24, -24). Fuses protect the 3VAC secondary that is used for FID ignitor (F1)
and electronic flow sensor voltages (F2).
