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

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.

in locating the trouble area when diagnosing fairly consist-

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

1.5 MACHINE SERVICE FEATURES

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.

1.6.1 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
Amphenol
452815).
A voltmeter can be used while the machine is static to measure the magnitude of a voltage. Manual operation may

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.

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.
Examples:

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:

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.

Basic Unit
Procedures outlined for removal and adjustment of the machine units are intended as guides. Adjustments should be kept close to the specification, but the procedures
preferred may vary among experienced customer engineers.
4.1 BASE
4.1.1 Diodes
Check diodes for shorts or opens by using an ohmmeter.
4.1.2 Arc Suppressors
Check the arc suppression RC units by substitution, never by running the machine with the arc suppressors removed. The RC units are highly efficient at reducing destructive arc.

2. Position backspace switch to operate with 1116-inch depression of the actuating arm.
4.3 FRICTION DRIVE
4.3.1 Friction Drive Service Check
The friction clutch should provide sufficient torque to deflect gram gage 275 to 325 grams when measured in the
following manner. Manually escape the machine until the hole in the escapement wheel is straight up. Use the blade in the gram gage. Hold the gram gage

ESCAPEMENT UNIT

Escapement Unit
Service
Check
Check the residual on the left yoke end for wear; clean dirty points and lubricate armature pivot. Clean oil and dirt
from escapement wheel. Too much torque on the friction drive may make action of escapement armature sluggish. The escapement wheel must be free of lubricants. Incorrect strap tension or improper make-time of the escape armature contact may cause double spacing or erratic escapement.
The contact operating pin should be free enough to allow pin to be rotated between the finger tips. A binding or canted operating pin usually indicates poor adjustment of the unit.

Escapement Gearing:
Keep escapement gear train lubricated
on machines that use the drum-type friction clutch. Keep
card chips and other foreign matter out of escapement gears
and friction drive. Faulty escapement may be caused by incorrect torque at the friction drive.
All
gear shafts protruding through bearing support must be pulled to the extreme forward position before tightening collars. Be sure
unsealed bearings are capped.

Adjust eccentric screw on knockoff bail (Figure 4-18) to cause bail to contact an attracted armature at both ends of unit between 13 degrees and 20 degrees. If the eccentricity is insufficient, inspect cam follower for wear. It may be necessary to pivot entire magnet unit around armature latching point to bring bail closer to armatures.
4.
Momentarily attract each armature electrically. The spring should cause the armature to fall away from the core. If the armatures hang up when the pick circuit is broken, they should be replaced; the residual magnetism causes excessive wear on the knockoff bail.

Interposer Bail Contact Assembly Adjustment
Bail-contact assemblies may be removed after removing the master bed plate or punch drive unit.
1. Both contact assemblies must have equal tension. Form stationary contact strap to require 30 to 35 grams to
raise it off its support. Forming should be within the area of the support strap to reflect a true condition. One method of forming the contact strap is to insert a straightened paper clip between the strap and its support. Form contact strap to obtain a point-to-point contact at outer tip of support strap. When strap is properly adjusted, a crack of light will appear at tip of support strap during measurement.
2. With contact assemblies removed, form operating strap near the mounting to require
20
to 25 grams to close contacts (Figure 4-20). Place gram gage finger under phenolic pad with 114-inch overlap when checking
adjustment; 50 to 60 grams should then be required to close contact and to raise stationary contact off support
strap (Figure 4-21).
3.
Reinstall the contact assemblies and adjust their mount­ing brackets for 0.017-inch contact gap with all arma­tures restored.

Sleeve Latching Surface Lead Distance:
Standard Method
This adjustment establishes the correct relationship between the clutch spring and the outer and inner sleeves
(Figures4-24 and
4-25).
1. Loosen the clamping screw. The clamping collar is a separate part and can be moved independently of the inner sleeve.
2.
Trip the clutch armature and turn the index wheel (not the drive pulley) forward until the inner- and outer­sleeve latching surfaces can be observed.
3. Move the clamping screw to an accessible position while holding the two sleeves with their latching surfaces
visible.
4. Turn the outer sleeve clockwise against the spring (Figure 4-25). The sleeve moves very easily in a counterclockwise direction. Therefore, keep the outer-
sleeve protrusion snug against the end of the spring to
avoid a false indication of the latching surface distances.
5. Position the inner-sleeve latching surface behind the
outer-sleeve latching surface as shown in Figure 4-25, and keep the clamping screw accessible.
6.
Tighten the clamping screw. While tightening this screw, press the clamping collar and inner sleeve toward the machine base, and keep the
duter-sleeve protrusion
against the spring.

some resistance, but not so loose that the spring will move inside the inner sleeve.
2. Turn the index wheel forward until the inner- and outer-sleeve latching surfaces are driven against the armature. (If you cannot turn the index
beyond this point, the clamp is too tight; and it is necessary to loosen the clamp more.)
3. Continue turning the index wheel forward to
347
degrees, 2 degrees beyond the point where the detent
drops into place. While turning the index wheel, hold
the
inner sleeve against the armature to overcome the
tendency of the sleeve to move backward.
4. Tighten the clamping screw securely.

Check the clutch adjustment (use 4.6.8) and repeat if
necessary.

Alternate Method
The abbreviated method can be used to make the adjust­ment after becoming more familiar with the operation
of
the clutch.
1. Loosen the clamping screw and use the index wheel to position the sleeve and collar to an accessible location.
2.
Hold the outer sleeve against the spring tip, and set the inner sleeve for the correct lead.
3. Tighten the collar so that the index can be turned with some resistance after the sleeves are stopped by the armature.

4.7.1. 1 Card Sensing Contacts
Inspect contacts for burning. Remove card particles and lint. One broken contact in a pair causes intermittent read failures.
4.7.1.2 Sensing Pins
Check that sensing pins operate separately. Pins sticking together cause reading failures by forcing both pins to enter the hole at the same time.
4.7.1.3 Pin Bail, Drive Link, and Arm Assembly
Inspect guide stud in the rear frame for wear. Adjust link and lubricate stud if necessary. Check for rust accumulation or wear.
4.7.1.4 Card Lever
Remove any accumulation of card dust around the card
lever.

4.7.2.3 Contact Gap
Late production units do not use shims.
1. Insert blank card and let pins rest against it.
2.
Remove contact cover and adjust common contact bar for minimum air gap of 0.020 inch and a maximum air gap of 0.030 inch (Figure 4-3 1).
4.7.2.4 Pin Bail Arm Eccentric
Normally, it is unnecessary to alter factory adjustment on pin-bail-arm eccentric stop. If adjustment is necessary, loosen locking screw and adjust eccentric to stop pin-bail arm when sensing pins are retracted 0.010 inch to 0.015 inch below surface of separators. Tighten locking screws.
4.7.2.1 Contact Pressure
Before installing a new contact molding, pre-form contact straps (Figure 4-30).
A

4.10 PROGRAM DRUM UNIT
4.10.1 Sensing Assembly Service
4.10.1.1 Card Life
Check
The program card should be changed daily when usage is heavy. The sensing wheels, in correct adjustment, should graze the surface of the program card. Improper tension on the program sensing arms shortens life of the program card. Worn program cards may cause elusive failures.
4.10.1.2 Drum Interchangeability
Determine interchangeability by checking all drums against a master drum. Replace worn gripper cam shafts.
2. Make certain that program drum shaft adjustable yoke is not loose.
3. Check for wear between end of shaft in program drum
and hole in column indicator wheel that locates and
seats drum.
4. Check for excessive
play in the escapement gear train,
while power is off.
5. Test friction drive torque.
6.
Be sure that the plastic safety cover is installed over the terminals.
Service time on these contacts is greatly reduced if the
method outlined in 4.10.2 is closely followed.
4.10.2 Sensing Assembly Adjustments
With the escapement armature stopping the escapement
ratchet tooth and machine power on, a zero reference point is established at any single column of the program unit by using the timing tool, part 453160 (Figure 4-35). The use of millisecond (ms) notation instead of 1/12 of an escapement tooth is to aid in determining relationships of the program unit timing to the escapement during a skip
operation and does not imply using an oscilloscope.
Perform operations in the order shown:
1.
Set the starwheel tension when the contacts are changed.
2. Set the starwheel duration.
3. Use only a starwheel with the correct duration to set the armlstarwheel timing.
forked
4.10.1.3 Drum Eccentricity
1.
Mount a program card with 4's punched at about
15-column intervals.
2. Space to the columns preceding the punched ones and observe the distance from the starwheel to the hole. Variation in the starwheel-to-hole distance is an indica­tion of drum eccentricity and should not exceed 0.003 inch.
4.10.1.4 Sensing Wheels
Wheels must pivot freely. Check for oxide deposit on pivots, and for proper lubrication. Sensing arm lever must
move freely on its pivot shaft.
4.10.1.5 Sensing Contacts
Contacts should seldom require adjustment. When trouble is suspected in this area, remember that there are several possible sources of trouble inside and outside the sensing unit that may make this adjustment erratic and unstable.
Check the following points before adjusting the sensing
contacts; it may save a callback.
1. Inspect straps and contact screw heads for pits and nodes.

4.10.3 Sensing Assembly Removal and Replacement
4.10.3.1 Program Sensing Unit
Remove program sensing unit as an assembly by taking out the two screws holding unit to base casting. On machines
where plastic top plate that supports sensing wheel arms is not pinned, scribe a line along its left edge to ensure proper relocation; contact duration and timing are easily lost by removing the top plate. When assembly is reinstalled on base, the shoulder on sensing unit should seat firmly on base; a locator pin ensures proper lateral placement. Check timing of contacts after reinstalling unit.
4.10.3.2 Sensing Contact Straps
Loosen the common plate screws so that tension is taken off contacts. Be careful not to bend contacts while removing or installling.
4.10.3.3 Program Shaft Assembly
No timing need be observed when installing a program shaft assembly. When installing auxiliary duplicate assembly, it must be timed to the program index. Punch a card in
column 1 and place it on the auxiliary drum. With program
index at column 1, install unit with starwheels reading column 1.
4.10.5 Program Cam Contacts Adjustment
The contacts are to be timed according to the timing on the
wiring diagram. Timing is set by the adjustable program
cam (Figure 4-38).
4.10.6 Program Drum interlock Arm (Split Hub) Adjust­ment
1. Raise starwheels.
2. Rotate interlock arm on serrated shaft to operate program handle switches with 0.002-inch to 0.005-inch travel remaining before switch plungers bottom.
3. Lower starwheels.
4. Position interlock arm along the serrated shaft for
0.015-inch to 0.020-inch clearance to the top of the program drum.

Print Assembly Adjustments
Adjustment of one component unit often affects another unit. Units should be adjusted in the order in which they appear in the following text.
4.11.2.1 Punch Drive and Print Yoke
Clearance between the yokes and guihes should be 0.015 inch to 0.020 the punch drive unit. This clearance causes rollers to
contact print interposers a minimum of 0.015 inch above
the start of cam action. Because the clearance cannot be
measured, it is obtained as follows:
1.
Oil (IBM # 6) the print interposers.
2. Remove belt guard and punch drive belt to remove tension on drive unit.
3. Loosen the two screws in the pin bail drive link.
4. Loosen the adjusting screw lock nut, holding screw, and two support screws in the drive anchor bar (Figure 4-29). Unhook the print drive spring.

is installed, form all tabs on each bail for 0.000-inch to 0.005-inch clearance to associ­ated operation ears on permutation bar, with latch assem­blies in restored position. This may be checked on a keyboard with its covers removed. Check tension required to just open a closed bail contact for each key that operates that bail; tension should be at least
15
grams. Bail contact air gap and tension on operating strap affects this tension and should be checked before a measurement is attempted.
4.12.2 Hook Support Bar Adjustment
Bar must be parallel with interlock guide bar, directly beneath it, along their longest edges, within 0.008 inch.
This is to prevent binding of the latch.
4.12.3 Permutation Bar Adjustment
Adjust the four setscrews that position the latch stop plate to allow bars to drop 0.042 to 0.048 inch. Measure a bar
near each holding screw. To measure, lay a 6-inch rule
across the top of the permutation bars. If the bar whose
travel is to be measured is lower than the 6-inch rule,
measure this amount and add it to the 0.042 to 0.048 inch given previously. Trip the latch and measure the distance

and with no interlocks affected,
weight on any keytop (except ERROR RESET, FEED, PROG ONE, PROG TWO, LEFT ZERO, DUP, NUMERIC, MULT PCH, ALPHA, and the space bar) must be sufficient to trip its latch assembly. The key must return to its normal position with a
logram minimum weight resting on the keytop,
when its latch assembly has been previously restored.
3. With key plate level,
and with no interlocks affected,
75-gram to 100gram maximum weight on the space bar and left-zero key must be sufficient to trip its latch assembly. The bar must return to its original position

6.4 STANDARD MODULAR SYSTEM (SMS)
Standard printed wiring cards are used in the modular type of packaging. These SMS printed wiring cards facilitate the
manufacturing process and permit standardization of cir­cuits. The pluggable printed circuit cards contain all the components and printed wiring necessary for a particular electrical function or functions. Other printed wiring cards are used as cable connectors and back panel voltage distribution buses.
The SMS single card (Figure 6-3) is made of an epoxy paper laminate material and is 0.056-inch thick, inches long and 2-112 inches wide. All of the electrical components are mounted on the front side of the standard SMS card form. Connections to the components are made on the back side of the SMS card form by printed wiring pattcrns that terminate at contacts at the bottom of the card. These contacts, labeled A through R, couple the sig­nal and standard service voltages to the circuit components
the card is inserted in the SMS socket. The printed
when wiring (land pattern) depends on the circuit configuration of the card.
SMS twin cards (Figure 6-3) are made of the same material used in single cards. Twin cards are wide; other dimensions are the same as for single cards. With twin cards, more circuitry can be packaged in a given space than with single cards.
The dualdensity twin card (Figure 6-3) has electrical components mounted on the front side of the card. This card contains as many as components are on both sides of the card and are made by printed wiring patterns that terminate at 32 possible contacts on the back side of the card. These contacts, A through voltages to the circuit components when the card is inserted into two vertically adjacent SMS card sockets (Figure 64).

SMS Printed Wiring Cards
6.4.1 SMS Card Receptacles
The pluggable printed circuit cards are inserted into SMS receptacles as shown in Figure 64. Although the contacts are all at one edge on the card insertion side of the SMS
receptacle, they pass through the receptacle in a staggered arrangement as noted in the figure. This staggering allows additional room for wire-wrapping or soldering of signal and voltage wires to the terminal pins.
6.4.2 SMS Locations and Pin Numbering
SMS locations are identified by:
