Safety Procedures
Safety cannot be overemphasized. To ensure personal
safety and the safety of co-workers, each CE should make it
an everyday practice to observe safety precautions at all
times. All CEs should be familiar with the general safety
parctices and procedures for performing artificial respira-
tion that are outlined in CE Safety Practices, Form
229-1264. For convenience, the -1 printing of this form has
been reproduced.
Always use a reliable voltmeter to verify that power is
actually off after using power-off switches. Although all
power supplies are provided with bleeder resistors to drain
off capacitor charges when power is dropped, it is wise to
check all capacitors with a meter before attempting
maintenance. A defective bleeder resistor could create an
unexpected hazard.
Anyone working near electrical circuits may accidentally
come in contact with live voltage.
Round off sharp edges on plastic guides; replace broken
guides.
Check that all applicable safety devices are on the
machine.
Check all safety devices for proper operation.
Do not permit machines to be run unattended with covers
open or removed.
Leave the escapement gearing cover in place at all times
when the machine is running.
Turn off power when tilting the base.
Use only IBM approved products. Read the labels. As a
general rule, cleaning fluids should be used only in an open
area. Breathing the concentrated vapors, even for a short
time,
may cause immediate reactions.
Review Customer Engineering Memorandums (CEMs) for
current safety practices.
b. Rings, wrist watches, chains, bracelets, metal cuff links,
shall not be worn.
CE SAFETY PRACTICES 2
All Customer Engineers are expected to take every safety pre-
caution possible and observe the following safety practices 13
while maintaining IBM equipment:
1. You should not work alone under hazardous conditions or 14,
around equipment with dangerous voltage. Always advise
your manager if you MUST work alone. 15.
2. Remove all power AC and DC when removing or assem-
bling major components, working in immediate area of 16.
power supplies, performing mechanical inspection of power
supplies and installing changes in machine circuitry. 17
3. Wall box power switch when turned off should be locked
or tagged in off position. ‘Do not Operate” tags, form 18.
229-1266, affixed when applicable. Pull power supply cord
whenever possible.
4. When it is absolutely necessary to work on equipment hav- 19.
ing exposed operating mechanical parts or exposed live
electrical circuitry anywhere in the machine, the following
precautions must be followed: 20.
a. Another person familiar with power off controls must
be in immediate vicinity. 21.
- Each Customer Engineer is responsible to be certain that
no action on his part renders product unsafe or exposes
hazards to customer personnel.
. Place removed machine covers in a safe out-of-the-way
place where no one can trip over them.
All machine covers must be in place before machine is re-
turned to customer.
Always place CE tool kit away from walk areas where no
One can trip over it (i.e., under desk or table).
Avoid touching mechanical moving parts (i.e., when lubri-
cating, checking for play, etc.).
. When using stroboscope —do not touch ANYTHING — it
may be moving.
Avoid wearing loose clothing that may be caught in machin-
ery. Shirt sleeves must be left buttoned or rolled above the
elbow.
Ties must be tucked in shirt or have a tie clasp (preferably
nonconductive) approximately 3 inches from end. Tie chains
are not recommended.
Before starting equipment, make certain fellow CE’s and
customer personnel are not in a hazardous position.
Maintain good housekeeping in area of machines while per-
forming and after completing maintenance.
c. Only insulated pliers and screwdrivers shall be used.
d. Keep one hand in pocket.
e. When using test instruments be certain controls are set
correctly and proper capacity, insulated probes are used.
f. Avoid contacting ground potential (metal floor strips,
machine frames, etc. — use suitable rubber mats pur-
chased locally if necessary).
5. Safety Glasses must be worn when:
a. Using a hammer to drive pins, riveting, staking, ete.
b.
Power hand drilling, reaming, grinding, ete.
c. Using spring hooks, attaching springs.
d. Soldering, wire cutting, removing steel bands.
e. Parts cleaning, using solvents, sprays, cleaners, chemicals,
etc.
f. All other conditions that may be hazardous to your
eyes. REMEMBER, THEY ARE YOUR EYES.

Section 2. Diagnostic Techniques
1.3 INITIAL APPROACH
The first step in troubleshooting is to reduce the possible
trouble sources to one of the five operations. Locate the
operation that breaks the correct sequence for the failing
function.
The second step is to vary the machine function to one in
which the failing operation occurs in another sequence.
This tests the same operation with a different input. For
example, interposer selection is faulty during keypunching
(2, 34, 5). Varying the function to manual duplication
(5-2, 3-4, 5) allows interposer selection from the pin-sense
input instead of the key input. The cause of the failure, if
in a particular input path,can be discovered in this way. If
the same operation fails, regardless of the input path used,
the failure is common to all paths.
Enough information may be gained in this way to find
the cause of the failure by using the wiring diagram and the
test probe.
For those troubles that cannot be found by using this
approach, refer to the appropriate section in Chapter 4.
Diagnosis of the complete failure of all machine opera-
tions should be preceded by a continuity check of the
fuses. If attempted punching fails to occur after a card has
been registered at the punch station, the card lever relay
should be checked first. Consistent blowing of fuses
indicates a short or a ground on the machine. Line
terminals and/or cam contacts can be checked, one at a
time, to locate this type of failure. Some common possible
sources of grounds are the starwheel contact and the latch
magnet contact.
1.4 DIAGNOSTIC FLOWCHARTS
Figure 1-4 defines the symbols used in the diagnostic
flowcharts (Figures 1-5 through 1-10). These flowcharts aid
in locating the trouble area when diagnosing fairly consist-
ent failures.

Figure 1-4. Diagnostic Flowchart Symbols
1.4.1 Start and Run Failures
To locate start and run failures (Figure 1-5), the starwheels
must be raised and blank cards must be used.
1.4.2 Card Transport Failures
Diagnosis of the failure causing incorrect card movement
should include an initial visual check to confirm that the
components of the card transport mechanisms are oper-
ating. When card transport failure occurs, any mark or nick
on the card will help to indicate the source of trouble
(Figure
1-6).
A change in registration during the duplication of one
punched card can be a false indication of card transport
failure. If the escapement moves while the sensing pins are
still up through the holes in the card, the card will be
retarded. The sensing pins usually leave marks on the card.
(See 1.4.4.)
Improperly inserting cards into the pin-sense station can
cause trouble. The card to be duplicated should not be
forced into the pin-sense station before registering the card.
1.4.3 Interposer Selection Failures
Interposer selection may be incorrect from either the
keyboard or pin-sense units, or both. If either unit operates
correctly, the circuits and components of the other unit
must be considered as a source of the trouble. If both units
fail, the trouble is assumed to be in the interposer magnets
and associated circuitry or in the interposer mechanism
(Figure 1-7).
Note that when the interposers have been tripped for any
reason, they must be restored by a drive-unit cycle.
To avoid confusion in diagnosis, the starwheels must be
raised to locate interposer selection failures.
1.4.4 Escapement Failures
Faulty escapement is defined as: escaping too far, not far
enough, not at all, or at the wrong time.
Program control is used with Figure 1-8 to locate
escapement failures. The program card should be punched
for alternate three-column duplications and two-column
