Safety Considerations
This product is a Saf ety Class I instrume nt tha t is provided wit h a prote c ti ve
earth terminal when installed in the mainframe. The mainframe, switch, and
all related documentation should be reviewed for familiarization with safety
markings and i nstructions be f ore operation or serv ice .
Refer to the WARNINGS on page 6 in this manual for a summary of safety
information. Safety information for preventive maintenance, testing, and
service foll ows a nd is also found throughout this ma nual.
WARNINGS and
CAUTIONS
WARNINGSERVICE-TRAINED PERSONNEL ONLY. The information in this
This section cont ai ns W AR N INGS which must be followed for your
protection and CAUTIONS whi c h mus t be followed to avoid dama ge to the
equipment whe n pe rforming instrume nt maintena nc e or re pa ir .
manual is for service-trained personnel who are familiar with
electronic circuitry and are aware of the hazards involved. To
avoid personal injury or damage to the instrument, do not
perform procedures in this manual or do any servicing unless
you are qualified to do so.
CHECK MAINFRAME POWER SETTINGS. Before applying
power, verif y th at the mainf r a me se t ti n g ma tc h e s the line
voltage and that the correct fuse is installed. An uninterruptible
safety earth ground must be provided from the main power
source to t he suppl ie d po we r co rd set.
GROUNDING REQUIREMENTS. Interruption of the protective
(grounding) conductor (inside or outside the mainframe) or
disconnecting the protective earth terminal will cause a
potential shock hazard that could result in personal injury.
(Grounding one conductor of a two-conductor outlet is not
sufficient protection.)
IMPAIRED PROTECTION. Whenever it is likely that instrument
protection has been impaired, the mainframe must be made
inoperative and be se cured against any u n intende d op e rat ion.
REMOVE POWER IF POSSIBLE. Some procedures in this
manual may be performed with power supplied to the
mainframe while prote ct ive cove rs are removed. Ene rgy
available at many points may, if contacted, result in personal
injury. (If maintenance can be performed without power applied,
the power should be removed.)
12 General InformationChapter 1
WARNINGUSING AUTOTRANSFORMERS. If the mainframe is to be
energized via an autotransf or mer (for voltage reduction) make
sure the common terminal is connected to neutral (that is, the
grounded side of the main’s supply).
CAPACITOR VOLTAGES. Capacitors inside the mainframe may
remain charged even when the mainframe has been
disconnected from its source of supply.
USE PROPER FUSES. For continued protection against fire
hazard, replace the line fuses only with fuses of the same
current rating and type (such as normal blow, time delay, etc.).
Do not use repaired fuses or short-circuited fuseholders.
CAUTION Static electricity is a maj o r ca u se o f co mp onent fa il u re . T o
preven t damage to t he electrical comp onents in th e switch,
observe anti-static techniques whenever working on the switch.

Table 2-1, "Performance Test Reco rd for th e E1 364A S w it ch Module," is a
form you may copy a nd use to record performan ce ve rif ica tion test result s
for the switch module. Pages 3 and 4 of Table 2-1 show switch accuracy,
measurement uncertainty (M.U.), and test accuracy ratio (TAR) values.
Switch Accuracy Accuracy is defined for closed-channel contact resistance and DC isolation
using the specific a ti ons in Appendix A of the E136 4A Use r’s Manual. The
closed-chann el resi stance and DC isolat ion specificati ons are single-sided,
meaning th at the r e is an uppe r limit OR a lower limit, but not both. In Table
2-1, either the "Minim um" or "Ma ximum" col umn will be blank fo r a
single-side d te st.

Testing the
Assembly
You can use the tests and checks in Table 4-2 to isolate the problem. See
Figure 3-1 in Cha pte r 3 or Figur e B-1 in Appendix B for locati ons of
replaceable p art s, dep ending on the ser ia l n umber of your switch module.
Inspect the switch for signs of a bnormal intern ally generated he a t such as
discolored printed circui t boa r ds or c omponents, dam a ge d insulation , or
evidence of arc in g . If ther e is dama ge , do not operate the switch until you
have correcte d the problem.
Checking Switch es /Jum pers
Verify that the logical addre ss se tt ing is set corre ct ly (factory set a t 120).
Verify that the interrupt priority jumpers are set correctly (factory set at
level 1). See the E1364A User’s Manual for information.
Checking the Switch PCA
Use the replaceable parts locator (Figure 3-1 or B-1, depending on the
serial number of your sw it c h module) to che c k the f ollowing:
• Verify that fuses F1 and F2 are go od.
• Check the closed-channel resistance of all relays using the procedure
in Chapter 2. Replace any bad relays.
• Check connecto rs P1 and J1 f or da ma ge .
NOTEIf the preceding steps fail to isolate the problem, use the schematics
included with this manual to perform compone nt-level tro ubl es hooting.

• ESD precautions
• Solderin g pr inted circuit boards
• Post-repair sa fet y ch ecks
ESD PrecautionsElectrostatic discharge (ESD) ma y da m ag e st a tic sensitive de vices in the
E1364A Switch Mo dule. This damage c an range fro m sl ight parameter
degradation to catastrophi c failure. When handling switch a sse mblies,
follow th es e gu ide lines to av oid damagin g sw itch compo ne nts:
• Always use a static-free work station with a pad of
conducti ve rub be r or si milar materia l whe n ha ndling
switch components.
• If a device requir e s sol d e ring, be sur e the as se mbly is
placed on a pad of conduc tive material . Also, be sur e that
you, the pad, and the soldering iron ti p are grounded to
the assembly.
Solde rin g Pr in te d
Circuit Boards
Post-Repair
Safety Checks
Some of the components on the etched circuit boards in the switch have
plated throu gh- holes that allow a sol de r path to both side s of the insulatin g
material. Sol de ring c a n be done from ei ther side of the boa rd with equ al ly
good result s. Wh en soldering to any ci rcuit board, kee p in mind the
following gui de li ne s:
• Avoid unnecessary component unsoldering and soldering.
Excessive replacement can result in damage to the circuit
board and/or ad ja c en t c omponents.
• Do not use a high-power sol de ring iron on etched circ ui t
boards, as exces sive heat may lift a conductor or damage
the board.
• Use a suction devic e or woode n toothpick t o rem ove
solder from co mponent mount ing holes. When using a
suction de vic e , be sure that the equipment is properly
grounded.
After making repa i rs to the E1364A Switch Module, inspect t he sw it ch for
any signs of abnormal internal ly generated hea t, suc h a s discolored pri nte d
circuit boar ds or co mponents, dam aged insulation, or evidenc e of arcing.
