INTRODUCTION
The Lathem 4000 Series time recorders are considered "standard” by thousands of
businesses and institutions because of their low initial cost and years of proven,
trouble-free operation. Many options are available with models to fit most business
needs for payroll and job timekeeping. The DWA-4000 series features touch plate
or automatic registration, right or left margin imprint, self reversing ribbon, digital
time display, coined steel type wheels, and easy installation. A particularly useful
feature of the DWA-4000 series is a keypad-programmable signal relay, capable of
ringing bells (or other signal devices) at selected times as well as inhibiting their
operation when not desired.
Read all directions carefully before operating or maintaining the DWA-4000.
Should it be necessary to return the unit, retain the original packing materials for
shipping. This operations manual is designed to provide basic operating instructions.
Minor maintenance and adjustments can also be performed easily and effectively
by referring to these instructions. For service beyond the scope of this manual,
con tact the dealer fixxn whom the equipment was purdiased or Lathem Time Company.

INSTALLATION INSTRUCTIONS
The DWA-4000 Series can be set on a desk or shelf, or mounted on a wall. Wall
p anting is recommended for payroll use because the clock can be installed at eye
level (about fourfeetfrom the floor to the card receiver). This provides the employee
with good aim for aligning his time card to the red pointer. Once the clock has been
installed, mount the bell(s) and or born(s) at the desired location(s). With the power
cord unplugged, wire the signal devices, through a single gang outlet box, to die
connector plate (two wiring schemes are shown in the diagrams below); mount the
connector plate to the outlet box, and insert the plug of the bell cord (Fig 1,22).

GSTARTED
Before proceeding, you need to know the “registration time format” of your time
recorder. The fourth digit in the model number indicates this format. EXAMPLE:
Since the fourth digit in the model number 4054 is a “4”, it will print with 0-59
minutes and 0-23 hours, along with month mid'date (See Page 2).
1. Plug the clock into the wall socket.
2. Install 9 V alkaline battery (not supplied).
3. Choose the time format desired. (Below)
4. Set the type section. (Below)
5. Set the digital face. (Page 9)
6. Program the signals. (Page 10)
7. THAT'S IT! You're ready to go.
TO CHOOSE THE TIME FORMAT
The clock defaults to the 12 hour format and will appear on the display as
12:00, if the 12 hour format is desired, no action is required. If 24 hour
format is desired:
1 .
Press

2. Locate these color-coded
components:
unlocking latch - blue (Fig. 1,1)
overthrow lever - red (Fig. 1,3)
open latch - white (Fig. 1,2)
3. Press the blue unlocking latch and
raise the type section to a locked
position, as shown in Figure 5.
4. Press the ted overthrow leva: back
until it “clicks”. The wheels are

NOTE: If your machine records in 1-12 hours, the PM hours are underlined. AM
hours are not underlined. Set time to the proper hour of die day to avoid errors
such as setting the day wheel to the next day at noon rather than midnight
5. Use a pointed object to rotate each
wheel until the correct time and day
are vertically aligned at the center
position, as shown (Fig. 6,23). If
you are using tenths (models with
4th digit of2 or 5), go to the section
“Setting Decimal Wheel with
Tenths” If you are using hundredths
or 0-23 hours, refer to the Dial of
Decimal Equivalents in Figure 7 to
determine the correct setting.
6. Rotate the main drive wheel to
advance the wheels for any time lost
during this setting procedure.
7. Release the white open latch by
pressing left. Gently lower the type
section.
8. Press firmly against face of the type section to lock into the closed position.
FIGURE 6
DIAL OF DECIMAL EQUIVALENTS
The dial in Figure 7 shows the tenths
andhundredtbs setting for each minute.
The small inner circle represents
minutes, the middle circle represents
tenths, and the outer circle represents
hundredths. For example:
45 minutes=.7 tenths = .75 hundredths.
Setting Decimal Wheel with Tenths
NOTE: Use only for recorders
printing in tenths (models witha4th
digit of “2” or “5”)
1. Rotate Tenths Wheel and set it at
“9”. A wheel is set when the desired
number is in line with 6:00 on the
clock face. FIGURE 7
2. Rotate Main Drive Wheel (Fig. 2,
16) until the Tenths Wheel clicks over from “9” to “0”.
3. Rotate Hour Wheel to set current hour.
4. Set correct minutes by rotating Main Drive Wheel one time each minute.
For example, at 10:05, rotate 5 times = 5 clicks * 5 minutes past ten o’clock.

The clock’s display and type section keep time according to line frequency (typically
60 Hz). During power failure, the unit automatically switches to an internal quartz
crystal to maintain time. A 9-volt non-rechargeable battery maintains display time
and memory for up to 15 accumulated days. When power is interrupted, the digital
display disappears with the exception of the flashing colon.
When power is restored, the display indicates the correct time and day, and all
programmed signals are intact If the PM indicator is flashing when power is restored
the type wheels may need to be reset and synchronized with the time display. To
verify whether or not the type wheels should be re-synchronized with the display:
L Press py^ To clear the flashing PM indicator and set the clock in
normal mode.
2. Use a piece of paper and make a registration on it by inserting it into the
card receiver.
3. Compare the registration with what is shown on the display. If they
match, there is no need for further action. If they don't match:
4. Go to "GETTING STARTED" on page 7 and follow the steps for
"SETTING THE TYPE SECTION” and "SETTING THE DIGITAL FACE".
Since the battery is non-rechargeable, it should be replaced when the display
indicates "Lo".

HOW TO CHANGE A RIBBON
La them time recorders have self-
reversing ribbons. With normal use, a
ribbon should last for many months or
even years...and when the time comes,
it is easy to change.
1. Remove the top cover and raise
type section (see “Raise the type
section on page 7.)
2. Remove the cotter pins (Fig. 8,7)
that retain the ribbon spools and
slide off old spools.
3. Liftribbon shield (Fig. 8,15)—use
pencil to support in up position.
4. Remove ribbon and replace with
FIGURE 8
new Lathem ribbon. Make sure the
ribbon feeds from bottom of spools
and runs BETWEEN reversing
fingers (Fig. 8,10), the red side aligned with date wheel(s).
5. I nstall cotter pins, remove pencil, and lower type section into place.
HOW TO CHANGE A TYPE SECTION
If your type section needs servicing,
you can easily remove and replace it
with a spare, without sending the entire
machine for service. Here’s how:
1. Remove the top cover.
2. Remove type section retaining ring
(Fig. 1, 12).
3. Unplug connectors (Fig. 9, 18).
4. Lift type section slightly and move
it to the right to release hinge pins
(Fig. 9,24) from their socket (Fig.
9,25). Unit will lift out (Fig. 9).

2. Unplug cord from wall outlet
3. Remove type section from main
frame (see “How to Change AType
Section”, Page 13).
4. Disconnect motor wire leads by
turning each screw 1/4 of a turn
counterclockwise (Fig. 10, 26).
5. Remove the motordrive clutch from
its shaft (Fig. 2, 8). The shaft has
LEFT HAND threads — remove

Operation Manual Addendum
DWA-4000
To improve the performance and reliability of this product, we have
replaced the previous 10 AMP Dry Contact Relay, with a 10 AMP
Solid State Relay. The new Solid State. Relay only operates with 24 -
240 VAC external devices (bells, horns, etc.). External DC powered
devices should not be connected to this unit.
Due to this change, please note the following corrections to this
manual:
Inside Cover Signal Relay is no longer a Form A (10 AMP) Dry
Contact, instead it should read 10 AMP Solid State
24 - 240 VAC Only.
