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 respira­tion that are outlined in
CE
Safety Practices,
S229-1264.
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
elect~ical 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.
CE SAFETY PRACTICES
All Cu~tomer Engineers ore .xp.cted to toke every sofety pre. caution po~~ible ond observ. the following safety procticas while mointoining IBM equipmant:

Diagnostic Techniques
Skip: Release,
1.3 INITIAL APPROACH
Release
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.

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.

1.4.5 Punch Drive Cycle Failures
Locate punch drive cycle failures with the starwheels raised (Figure 1-9). Diagnosis of clutch failures should include an initial manual cycle of the punch drive unit. Incorrect clutch overthrow or a defective detent can be found while performing this operation
1.4.6 Printing Control Failures
The program card used for locating escapement failures can be used for locating programmed printing failures. Diagnos­tic flowchart is Figure 1-10.
1.5 MACHINE SERVICE FEATURES
The 29 Card Punch has two diagnostic features that have been incorporated to aid the customer engineer. These are:
Motor switch
Test probe
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)
contains a neon indicator in
series with
a
resistor. One lead of the indicator is connected
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
1.6.1 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
1.6.3 Jumpering
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.
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
Amphenol
connectors, use AMP* disconnect tool (part
452815).
CAUTION The machine should not be left static in the middle of an operating sequence for a long period of time.
1.6.4 Measuring
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.
A voltmeter can be used while the machine is static to measure the magnitude of a voltage. Manual operation may

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
while
troubleshooting could damage several relays. All 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

4. Punch clutch detent pivot stud (worn or loose)
5. Punch clutch overthrow (too much or too little)
6. Relays (high resistance shorts or hold points burned or

7.
High-speed cam contacts (binding roller, strap tension,

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.
Examples:
In a reed-relay machine with a five-position field
programmed, the operator keys-in 1, 2, 3, 4, 5,
6.
The
machine punches out
2,3,4,5,6 when the left-zero key is pressed. In a wire-contact relay machine with a five-position field programmed, the operator keys-in
1,2,3,4,5,6. The machine punches 3, 3, 4, 5, 6 when the left-zero key is pressed.
1.7.1.2 Intermittent Lossof Bits
Common causes for loss of information during read-in or read-out operations are:
1. Keyboard latch or bail contact adjustments
2. Keyboard restore bail contact adjustment
3.
Error reset contact or backspace switch intermittently breaking contact
4. Loose slip-on connectors to punch interposer magnet unit
5.
Loose connectors in 0-volt or 48-volt net to LZ relays
6. Punch
CBs out of adjustment.
1.7.2 Diagnosis of "Heavy" or Stiff Keyboards
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:
Check to be sure that the proper lubricant is
used in the correct places. Refer to "Chapter
3."
Interference:
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 pressure required should not exceed 10
grams
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 duplication of 80 columns (using
blank
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.
29
FEMM
(4169)
1-11
4.
Place the machine in numeric shift and time the automatic duplication of
80
columns (using
punched
cards). Timing should be 4 to
4.5
seconds.
5.
If
timing exceeds the limit, slow action is due to the interposer magnet assembly: a. Excessive
magnet-to-armature
air
gap.
b. Interposer
bail contacts.
1.7.3 Stadter
The base should not be raised or lowered by using the stacker plate as a handle; relative position of the stacker plate to the stacker assembly may be changed and may require readjustment. Improper adjustment of the traveling card guide
can
cause difficulties in reading the end portion
of a card.
1.7.4 Starwheel
Adjustment
The
29
Card Punch is designed so that the starwheel
duration is about
9
ms. One tooth on the escapement wheel
equals
12
ms. This timing is critical because too much or too little duration could cause relay points to arc. This could be compounded if the relays develop a tacking condition.

Preventive Maintenance
Section
1.
Basic Unit
The customer engineer's approach to preventive mainte­nance is important to machine performance and customer satisfaction. Effective scheduled maintenance is essential for good machine performance. Time spent systematically on scheduled maintenance results in complete inspection of major machine
uriits. Figure 3-1 is a suggested guide for
maintaining a standard machine if normal usage is 40 hours
per week. Refer to Field Engineering Maintenance Manual,
Motors, Generators, Relays, Circuit Breakers, Test Instru-
ments, Miscellaneous Components,
S225-3422, for addi-
tional scheduled maintenance information.
3.1 CLEANING
A clean machine is important to good performance. While cleaning a machine, observe the bearings, cams, linkages, and other moving parts for rust accumulation. Rust accumulation indicates wear. Reduction of corrective main­tenance is the goal of scheduled maintenance.
3.2 ADJUSTMENT
A properly adjusted machine is more reliable than one that has had compensating adjustments made for wear or malfunction in some other area. As part of a PM routine, check the following adjustments regardless of operating conditions. A quick check of the same areas is also recommended at the time of
each.maintenance call. The
adjustments for these areas are in Chapter 4.
Friction clutch Escapement
Feed throat Punch clutch CBs Program unit
3.3 SAFETY
Preventive maintenance also implies the prevention of accidents to operating and maintenance personnel and concern for their health and well-being.
I
DANGER Do not permit machines to be run unattended with covers open or removed.
3.3.1 Safety Devices
Check that all applicable safety devices are on the machine. If they are operating devices, check them every time you perform a routine PM. Refer to
CEMs for current safety
information.
3.3.2 Electrical Hazards
DANGER Anyone working near electrical circuits may accidentally come in contact with live voltage.
Be alert and careful.
Note:
Immediate mouth-to-mouth resuscitation is
imperative for unconscious victims of electrical shock.
Always disconnect voltage.
3.3.3 Chemical Hazards
DANGER
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.
3.4 LUBRICATION
Lubrication points are shown in Figures
3-2
through
