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
practices and procedures for performing artificial respira-
tion that are outlined in
For convenience, the
CE
Safety Practices,

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
elect~ical circuits may accidentally
come in contact with live voltage.

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.
1.3 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, 34, 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 operations 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.
1.4.2 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 operating. 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 l nterposer 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.

These flowcharts aid
in locating the trouble area when diagnosing fairly consist-
ent 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

to the power supply. The other lead is used to trace circuits
leading to coils or magnets. A jack is provided on the power
supply chassis.
CAUTION
Care must be used when probing relay points because the
point of the probe might spread the pin connectors and
cause the reed switch to make poor contact or break the
pin. Be careful in the use of the test probe; an accidental
short could tack several relay points. The probe should
not be used to estimate circuit voltages. Use the meter for
voltage measurements.
Reed relays should be probed through the top of the
bobbin because the vertical rows of holes on the land
pattern for a particular relay position do not, in all cases,
connect to the relay connector.
Note: When probing P3, a false indication may occur; P3
appears not to make. This is due to the timing relationship
between the short duration of P3
(7
ms) and the 60-Hz
negative line pulse used to bias the probe.
1.6 SERVICING TECHNIQUES
1.5.1 Motor Switch
The motor switch turns the motor off and allows other
areas of the machine to remain energized. It is useful when
manually cycling the machine. Some adjustments are made
with the motor stopped.
1.5.2 Test Probe
The test probe (Figure 1-1

1.6.1 Forcing
Extra pressure can be applied to various components to
simulate malfunction. For example, the friction drive can
be forced or retarded manually at the top of the program
drum, or finger pressure can be applied to the escape
magnet armature to help or hinder its operation. Magnetism
of the escape magnet can be detected, and its strength
estimated with any lightweight steel blade (screwdriver or
burnishing tool).

1.6.2 Interrupting Machine Operation
The sequence of machine operation can be interrupted and
controlled by removing a lead from the controlling magnets. For
example, a lead can be removed from the escape
magnet or from the punch clutch magnet. Operation can
then be controlled by retouching the lead long enough for
one operation to occur.
CAUTION
The machine should not be left static in the middle of an
operating sequence for a long period of time.
The source of undesired operations can often be located
by removing leads along the undesired circuit until the
source is found.
This should not be done in reed-relay
circuits with power on.
1.6.3 Jumpering
Portions of circuitry suspected of being open can be
jumpered to determine whether they are open. It is also
useful to jumper the desired voltage into a circuit, to
determine how much of the circuit operates correctly.
Circuit Card Tab Connections:
Individual wires are easily
removed from the connectors to facilitate circuit diagnosis
or component isolation. To remove wires from
connectors, use AMP* disconnect tool (part
1.6.4 Measuring

little or no voltage.
A
secondary short may not blow the
primary fuse.
1.6.5 Cycling Manually
Turn the motor switch off. Observe machine functions
while manually operating the escapement gear train and the
punch clutch. This allows voltages to be checked at any
time during the machine cycle.
1.6.6.3
Reed
Relays
When inserting reed relays on the circuit board, care must
be exercised not to exert pressure on the coil portion of the
relay. Pressure exerted on the coil can cause the relay to
flex, and breakage of the glass reed switch may occur. To
prevent this breakage, the relay must be positioned and
pressed on the card with -equal pressure exerted on each of
the plastic ends of the relay (Figure 1-12).
A short caused by a defective part or a slip of the hand
troubleshooting could damage several relays. All
while
relays in the circuit between the short and the line should
be checked because the sudden surge of current could cause
the interceding relay points to weld or develop a
condition.

1.6.6 Interchanging Units
Keyboards, relay boards, or relay gates may be inter-
changed with other machines of the same type and feature
configuration. This can help isolate suspected units when
diagnosing intermittent troubles.
1.6.6.1
Relay Gate
The relay gate in either type of machine is easily remove-

the guide tracks through the slots provided. In the
wire-contact relay machine, first slide one tab out of the
slot, then slide the other tab out.
1.6.6.2
Arc
Suppression
Arc suppression is necessary for the proper operation and
longevity of the reed-relay switches. If trouble is suspected
in an arc suppression network, it
must
be substituted with
another.
CAUTION
Removal of arc suppression for diagnosis can cause
considerable damage as well as faulty operation.

7.
High-speed cam contacts (binding roller, strap tension,
or loose contact pile-up)
8. Interposer bail contacts (strap tension, air gap, or
contact condition).
An intermittently failing machine should not be returned to
the customer without investigating every suspected cause of
the failure.
1.7.1 Left-Zero Feature
1.7.1.1 Left-Zero Overflow/lncorrect Punchout
Incorrect punchout of left-zero information occurs if the
operator keys-in more digits than the field can contain.
Reed-relay machines continue shifting the bits in the
registers; the first digits keyed-in are lost. Wirecontact relay
machines accumulate the overflow of bits in the first
register.

1.7.2 Diagnosis of "Heavy" or Stiff Keyboards
CBs out of adjustment.
To isolate the source of trouble when a keyboard feels
"heavy" or stiff, make the following checks.
1.7.2.1 Key Pressure
Key pressure can be affected by lubrication, by interference
between the
keystem and the cover, or by sluggish interlock
disks.
Lubrication:
used in the correct places. Refer to "Chapter
Interference:
Check to be sure that the proper lubricant is
3."
Check to be sure that the keyb\uttons are
centered within the holes in the cover face.
Interlock Disks:
Check for dirty, magnetized, or oily
interlock disks.
1. With the machine on, press the P-key.
2. Using a gram gage, operate the P-key; 55 to 65 grams
should be read. Note the actual pressure required to
operate the key.
3. Press the Q-key.
4. Using the gram gage, operate the P-key again. The
grams
pressure required should not exceed 10
more than
the reading noted in step 2.
5. If step 4 failed to meet the requirements specified,
remove the interlock disks.
a. Wash the disks and the race in IBM cleaning fluid to
remove all traces of oil or dirt.
b. Test for magnetism by sliding the disks down an
inclined steel surface; replace all sticking disks.
1.7.2.2 Keyboard Cycle Time
To check for slow keyboard restore:
1. Open keyboard base and place machine in numeric shift
by inserting a card between the numeric
keystem
contacts.
2. Feed a card to column
1.
3. Short latch contact 6 and time the punching of 80
columns. Timing should be approximately 4.5 seconds.
4. If the time exceeds
7
seconds, repeat the punching
operation with one thickness of card inserted between
the keyboard restore magnet armature and the core.
5. If an increase in speed of the punching operation occurs,
adjust the armature-tocore clearance to 0.005 inch. (No
increase in speed indicates a slow machine cycle.)
Note:
Keyboard restore magnet coils are connected in
parallel. A short or open in either coil upsets the balance of
the circuit. Symptoms include slow keyboard cycles,
double punching, or extra spaces.
1.7.2.3 Machine Cycle Time
To check machine cycle timing:
1. Install an
80column autodup program card on the
program drum.
2. With the machine in alphabetic shift, time the automatic
blank
duplication of 80 columns (using
cards). Timing
should be 4 to 4.5 seconds.
3.
If timing exceeds the limit, slow action is due to the
punch clutch, the friction clutch, or the escapement
mechanisms.
