Section 1. Introduction
Link's System 1100 Tonnage Monitors are a family of microprocessorbased instruments that can determine, display, and compare
developed forces with preset limits for a variety of machines mechanical power presses, press brakes, powdered metal presses,
forging presses, die cast machines, injection molding machines,
cold headers, and similar machines - that use large forces in
production processes. System 1100 Tonnage Monitors are simple, for
ease of use in everyday production, yet sophisticated enough to be
used as analytical instruments by press and tooling engineers.
These instruments can help:
#PROTECT MACHINES from excessive bearing wear and broken frames
and load transmission components. Properly applied and used
System 1100 Tonnage Monitors provide setup personnel with
information about total and distributed machine loads (both
forward and reverse loads can be displayed). By operating
machines within capacity with a properly distributed load,
short term catastrophic machine damage due to overload or
maldistributed load, and long term fatigue of machine parts,
and wear of bearing surfaces can be reduced. The monitoring
capability of the System 1100 will help prevent continuing
overloads by stopping the machine if tonnage exceeds preset
limits during a machine cycle.
#PROTECT DIES or other tooling from production process
malfunctions that don't damage the tooling due to one out of
tolerance stroke (several bad strokes may occur on high speed
machines that can't stop in one stroke).
#ASSESS TOOLING WEAR of shear surfaces on blanking, piercing,
and trimming operations. Early indication of tooling wear can
help schedule tool repair and extend tooling life by reducing
the severity of wear before sharpening is indicated.
#CONTROL PART QUALITY by providing the load information
necessary for consistent tooling and machine setup. Out of
limit hits will stop the production process, allowing
corrections before large numbers of scrap parts are generated.
#CONSERVE ENERGY by using only the tonnage necessary to make a
part. A few thousandths of shut-height misadjustment can mean
tens of tons of unnecessary force in coining and forming
operations on larger presses. Every excess ton of force takes
energy out of the drive system with resultant increased
electric bills. The System 1100 Tonnage Monitors can also
help match tooling and machines so that larger than necessary
machines aren't used in low tonnage applications, again saving
energy.
#MEET OSHA REQUIREMENTS to operate within machine capacity.
OSHA's General Industry Standards 29CFR1910.217 (f) (4)
require mechanical power presses to be operated within tonnage
rating. System 1100 Tonnage Monitors provide this information
simply and directly.
System 1100 Tonnage Monitors offer a wide range of practical
features and design parameters that make them extremely versatile
in application and use. Some of these features are:
#Layered accessibility to controls allows easy display of load,
setpoint information and alarms, but all operating mode and
setpoint selection controls require the use of a keyed
selector switch for supervisory control. Selectable keyed
reset after an alarm is standard on all units.
#Two and four channel units are available to provide versatile
and correct monitoring of a variety of machines.
#Large 4-digit LED displays continuously display forward or
reverse loads in tons for all channels and the total.
#Multi-colored LED displays graphically show the peak tonnage
relative to the high and low setpoints for each channel.
#A 2 line by 20 character LCD display and 25 key keyboard
provide easy access to all tonnage monitor functions.
#Settable tonnage limits provided are: Maximum allowable
forward tonnage (HIGH SETPOINT), minimum required forward
tonnage (LOW SETPOINT), and maximum allowable reverse tonnage
(REV SETPOINT).
#One hundred twenty-three setups containing as many as 60
setpoints can be stored in non-volatile memory and recalled by
job number or name.
#Data windows allow for close monitoring of even complex dies
by not only checking absolute peak tonnages, but also checking
up to four additional 'local peaks' created by staggered
tooling. This feature requires a rotary cam switch or limit
switch for each data window used.
#Automatic Setup allows all setpoints (peak setpoints and all
data window setpoints) to be calculated and set automatically
by the System 1100.
#The number and types of alarms are automatically recorded by
the System 1100 through the alarm counters (machine rating,
high setpoint, low setpoint, and reverse setpoint alarms).
#A stroke counter, presettable batch counter, parts counter,
and quality check counter are standard.
#An RS-232 port is provided as standard equipment for
interfacing to personal computers. With optional software
package tonnage signatures captured by the System 1100 can be
displayed and stored on a personal computer.
#Signal output terminals are provided for each channel and the
total to drive a recorder or oscilloscope.
#May be calibrated either statically or dynamically.
#Operates up to 2,000 strokes per minute.
1.1 System Overview
Figures 1 and 2 show the components that are contained in the
System 1100 for the self-contained and the panel-mount versions
respectively.
The self-contained unit (Figure 1) houses all the electronics of
the System 1100 Tonnage Monitor. External connections are required
only for strain links, press control stop circuit, and optional
rotary cam switches.
Figure 1. System Components of Self-contained System 1100.
The panel-mount unit (Figure 2) separates the Operator Interface
Terminal electronics from the Logic Unit electronics. This
configuration is useful when the tonnage monitor display is to be
mounted in a panel where depth is limited, or when the display is
to be mounted a long distance from the strain gauges.

Section 2. Operation
2.1 The Operator Interface
The operator interface is the means by which the operator can
control the operation of the System 1100. The following features
of the Operator Interface will be referred to extensively in this
manual and so the operator should be familiar with them. A picture
of the Operator Interface is located on the last page of this
manual and can be folded out for viewing.
1)Tonnage Displays. The tonnage displays are large 4-digit
red LED displays used to display peak tonnage.
2)Tonnage Bar-graphs. The tonnage bar graphs are ten
segment multi-colored LED displays used to show peak
tonnage relative to the HIGH and LOW setpoints and to
indicate high and low alarms.
3)Mode Selector Keyswitch. The mode selector keyswitch is
used to control the operating mode of the System 1100 and
to gain access to tonnage setpoint limits and
configuration data.
4)Indicator LEDs. The three indicator LEDs are used to
indicate Auto Setup mode, Low Limits Off, and an active
Stop Circuit.
5)LCD Display. The 2 line by 20 character LCD display is
used to display messages and access the menus of the
System 1100.
6)Keyboard consisting of 25 keys. The keyboard is used to
enter setpoints, configuration data, clear alarms, and
for all other operator input that is required.
2.1.1 Tonnage Displays and Bar Graphs
The tonnage displays are used to display the peak forward and
reverse tonnage measured by the System 1100. Selection of forward
or reverse peak tonnage for display is discussed in the next
section.
The bar graphs are used to graphically display the measured forward
tonnage relative to the high and low setpoints. The top segment on
the bar graph represents the high setpoint, and the bottom segment
the low setpoint. The segment representing the measured tonnage
relative to the high and low setpoints is lighted each time a new
tonnage is displayed.
2.1.1.1 Display of Alarms
Alarms are generated when the System 1100 detects that the measured
tonnage has exceeded a preset value (high setpoint, reverse
setpoint, or machine rating) or in the case of low setpoints, has
not exceeded a minimum value. Alarms are indicated on the System
1100 using the tonnage displays and the bar graphs.
Machine rating alarms are generated when the measured tonnage
exceeds 125% of the channel rating, where the channel rating is the
machine rating divided by the number of channels. Machine rating
alarms are indicated by a flashing tonnage display on the channel
on which the alarm occurred.
High setpoint alarms are generated when the measured tonnage for a
channel meets or exceeds the high setpoint for that channel. High
setpoint alarms are indicated by the top red segment on the channel
bar graph flashing.
Low setpoint alarms are generated when the measured tonnage for a
channel during the stroke does not meet or exceed the low setpoint.
Low setpoint alarms are indicated by the bottom red segment on the
channel bar graph flashing.
Reverse setpoint alarms are generated when the reverse tonnage for
a channel meets or exceeds the reverse setpoint for that channel.
Reverse setpoints alarms are indicated by a flashing reverse
tonnage (reverse tonnages are indicated by a minus sign in the
tonnage display).
2.1.2 Keyboard Use
The upper left portion of the System 1100 keyboard is the numeric
keypad. The numeric keypad is used for entering setpoints,
configuration data, and other numeric data. The remaining keys
have special functions that are explained in the remainder of this
section.
2.1.2.1 AUTO SETUP key
The AUTO SETUP key is used to access the Automatic Setup function
of the System 1100. The operator must be in the Main menu and have
the keyswitch in the PROG position to access this function.
Automatic setup stores the highest and lowest peak tonnage from
sixteen successive strokes. High setpoints are calculated as the
highest peak tonnage plus a user selected percentage of channel
rating (the auto setup tolerance), low setpoints are the lowest
peak tonnage minus the auto setup tolerance, and reverse setpoints
are the highest reverse reading plus the auto setup tolerance.
Automatic setup sets all setpoints, high, low, and reverse, for the
peak and for all data windows (if used).
When Automatic Setup is begun by the operator, the AUTO SETUP
indicator will turn on and the automatic setup screen will appear
as shown below.
AUTO SETUP TOL: 5%
STROKES NEEDED: 16
While the keyswitch is in the PROG position, the automatic setup
tolerance will flash, indicating that it can be changed. The
tolerance can be adjusted up to 30% or down to 1% using the up and
down arrow keys respectively.
The number of STROKES NEEDED will count down as the operator cycles
the machine. When all sixteen strokes have been made the System
1100 will calculate and store all setpoints. The AUTO SETUP light
will then go out, and the Main menu will again appear. The
setpoints are stored in the current setup just as if they had been
entered manually.
The automatic setup procedure can be aborted at any time before the
sixteenth stroke by pressing the CLEAR key or the EXIT key. The
previously entered setpoints will then remain in effect.
WARNING! While in Automatic Setup Mode (when AUTO SETUP light is
on) the System 1100 is effectively BYPASSED. All high, low, and
reverse alarms are turned OFF. Only machine rating alarms are
active.
The LOW LIMIT ON/OFF key is used to switch the low setpoint limits
on or off. This functions is accessible only while the keyswitch
is in the PROG position.
2.1.2.3 DOWN TIME CODE key
The DOWN TIME CODE key is for use with the Link System Tonnage
Monitor local area network system and is not used at this time.
2.1.2.4 TONNAGE FORWARD/REVERSE key
The TONNAGE FORWARD/REVERSE key is used to switch the tonnage
displays between forward and reverse tonnage. When reverse tonnage
is selected a minus sign will appear at the left of each tonnage
display, when forward tonnage is selected the minus sign will go
out.
2.1.2.5 HELP key
The operator may request a Help screen from the System 1100 by
pressing the HELP key. The Help screens are intended to aid the
operator by giving additional information and explanation of the
current stage of the program sequence. Some Help screens may be
more than two lines long. If the last character on the screen is
a down arrow, more help information is available. The operator can
press the down arrow key to view the additional lines. The
operator can terminate a help screen and return to the program at
any time by pressing the EXIT key . If no help screen is available
for the present program sequence, a message will inform the
operator that a help screen is not available.
2.1.2.6 CLEAR key
The CLEAR key is used for two main functions. The first function
is to remove any data input in progress. If the operator keys in
the wrong data but has not yet pressed the ENTER key, he may press
the CLEAR key to remove the entire data input. The correct data
may then be keyed in. The CLEAR key cannot remove any data once it
has been entered with the ENTER key.
The second function of the CLEAR key is to clear stops, alarms and
errors. If a counter reaches its programmed limit and stops the
machine, the CLEAR key can be pressed to reset the counter and
allow the machine to be restarted. If an alarm is present, such as
channel 3 high setpoint alarm, or and error is present, such as
ERROR 40 - End Of Cycle cam failure, the CLEAR key can be pressed
to clear the alarm or error.
2.1.2.7 CONTRAST key
The CONTRAST key is used to adjust the contrast of the LCD
display. The display can be adjusted brighter or dimmer by
holding down the CONTRAST key then pressing the up or down arrow
keys respectively. If the keys are held down this function will
automatically repeat to avoid having to repeatedly press the keys
for large adjustments.
2.1.2.8 HIGH SET and LOW SET keys
The HIGH SET and LOW SET keys are used to display the high and low
setpoints on the tonnage displays. The setpoints will be displayed
as long as the key remains depressed.
2.1.3 Mode Selector Keyswitch
The Mode Selector Keyswitch is a three position keyswitch. The key
can only be removed in the RUN position.
RUN - This is the normal operating mode of the System 1100.
When the key is in this position, the operator can only view
setpoint limits, and counter information. Tonnage setpoint
limits and counter limits and count values cannot be altered
or cleared.
PROG - This is the program mode of the System 1100. When the
key is in this position, tonnage setpoint limits can be
changed or turned off, setups can be stored, recalled or
removed, and counter limits can be changed, turned off, and
count values cleared.
BYPASS - This mode is intended for use while die setting.
While in Bypass mode all high, low, and reverse setpoint
alarms are turned OFF. Only machine rating alarms are active
while in bypass mode.
2.2 Menu Selection
The LCD (Liquid crystal display, at the right-top of the operator
interface) provides the operator with information needed to program
the System 1100. This is done by displaying a menu (list of
choices) and allowing the operator to select one of the menu items.
The blinking pointer is called the cursor and is used to identify
which item on the list is currently selected. The cursor can be
moved to a different choice on the menu using the up and down arrow
keys (see the figure on the foldout in the back of the manual).
Once the cursor is on the item desired, the operator can press the
ENTER key to get further information about that item. The operator
is not required to memorize any function names or keyboard entry
sequences.
2.2.1 Main Menu
The Main menu is the first list of options offered to the operator
during programming of the System 1100. The Main menu contains six
functions from which to choose. The Main menu is shown below.
MAIN $DISPLAY $
MENU $SETPOINTS $9
STO/RCL COUNTERS
ERRORS
CONFIG
Only two menu options can be shown at one time on the LCD display;
the remaining options are accessible by using the up and down arrow
keys. If options are available either above or below the currently
displayed menu options, then up or down arrows will appear on the
right side of the menu indicating so.
To select an option from the menu list, move the cursor to the
desired option using the up and down arrow keys then press the
ENTER key.
Note that if data windows are disabled in the Config menu the
DISPLAY option will not appear in the Main menu.
2.3 Tonnage DISPLAY Selection
If the System 1100 has been configured for use with data windows
(section 2.8.6), the DISPLAY option will appear as the first
selection in the Main menu. The Tonnage Display menu, simply
called 'DISPLAY' in the Main menu, is used to select which tonnage
reading will appear on the tonnage displays. The Tonnage Display
menu is shown below.
TONNAGE$ PEAK $
DISPLAY$ TONNAGE $9
DATA
WINDOW 1

WINDOW 4
The up and down arrow keys are used to select the desired tonnage
for display. When the desired tonnage is shown on the menu the
corresponding tonnage readings will be displayed on the tonnage
displays.
Exiting the Tonnage Display menu automatically switches the tonnage
displays back to the peak tonnage. The Tonnage Display menu can be
exited by pressing the EXIT key or the CLEAR key.
2.4 SETPOINTS
If the System 1100 has been configured for use with data windows
(section 2.8.6), the Setpoints menu will appear when the SETPOINTS
option is selected from the Main menu, if the System 1100 has not
been configured for use with data windows, the screen shown in
section 2.4.1 will appear.
The Setpoints menu (shown below) allows the user to select a group
of setpoints for viewing or editing and to turn on or off the use
of individual data windows.
To view or edit a group of setpoints, select the desired group
using the up and down arrow keys, then press the ENTER key.
Setpoints for data windows that are turned OFF cannot be viewed or
edited until they are turned ON.
To turn on or off the use of a data window, first move the
keyswitch to the PROG position. Next, select the desired data
window using the up and down arrow keys, then press either the ON
or OFF key.
2.4.1 Editing Setpoints
The Setpoints Editing screen allow the operator to view and edit a
group of setpoints. A group of setpoints consists of a high, low,
and reverse setpoint for each channel. A typical setpoints editing
screen for a four channel System 1100 is shown below.
Because of the limited size of the LCD display, not all setpoints
can be shown at one time. When additional setpoints are located
either above, below, right, or left of the displayed setpoints,
arrows indicating so will appear on the right side of the screen.
While the keyswitch is in the BYPASS or RUN positions the operator
can only view the tonnage setpoint limits. When the keyswitch is
in the PROG position the currently selected setpoint limit will
flash indicating that it can be changed. To change a setpoint,
first select it using the up, down, left, and right arrow keys,
then enter the new setpoint over the old using the numeric keypad.
When finished entering the setpoint, press the ENTER key.
The group of setpoints shown above is for the absolute peak
tonnage. Data window setpoint groups are indicated as shown below
with the data window number appearing in the upper left corner of
the setpoints editing screen.

.4
CH1 11.3 9.3 96
CH2 11.3 9.2 .4
CH3 10.9 9.1 .4
CH4 11.2 9.2 .4
The following rules apply to setpoint limits:
1) High setpoints cannot exceed 125% of channel rating.
(channel rating = machine rating/number of channels)
2)A Low setpoint must be lower than the channel's high setpoint.
3) Reverse setpoints cannot exceed 125% of channel rating.
2.4.1.1 Turning Reverse Setpoints ON/OFF
Reverse setpoints can be enabled or disabled in the setpoints
editing screen by selecting any reverse setpoint using the cursor
keys, then pressing either the ON or OFF key. This will enable or
disable ALL reverse setpoints (peak and all data windows).
Enabling and disabling of reverse setpoints can only be done while
the keyswitch is in the PROG position.
REV-SET (ON)
2.5 STO/RCL
In the System 1100, the information which includes all peak and
data window tonnage setpoint limits is called the current setup.
Since tonnage setpoints limits are set according to the tonnage
required to make a good part for a particular die, and they must
usually be changed each time the die is changed. Ordinarily this
would require either manually entering new setpoints or executing
the automatic setup function. Manually entering large numbers of
setpoints can be tedious, and using automatic setup each time a die
is changed gives no indication of what tonnage the die operated at
the last time it was used. What is needed is a permanent record of
the required tonnage for each die. The System 1100 provides for
permanent storage of up to 123 different setups through the Sto/Rcl
menu. The Sto/Rcl menu is shown below.
STORCL$STORE $
MENU $RECALL $9
REMOVE
The Sto/Rcl menu provides the operator with the capability to store
setups to backup memory, recall setups from backup memory, and
erase setups from backup memory.
2.5.1 STORE
The Store menu allows the operator to assign a job number and
description to the current setup, and to save the current setup to
backup memory. The Store menu is shown below.
STORE $ENTER JOB# $
MENU $ENTER DESC.$9
STORE JOB
2.5.1.1 ENTER JOB#
The ENTER JOB# screen allows the operator to assign a six digit job
number to the current setup. When the ENTER JOB# screen is
entered, the job number of the current setup is displayed as shown
below.
ENTER JOB NUMBER:
000025
While the keyswitch is in the PROG position, the job number will
flash indicating that it can be changed. To change the job number
enter the new number over the old using the numeric keypad, then
press the ENTER key.
2.5.1.2 ENTER DESC
The ENTER DESC screen allows the operator to assign a 16 character
description to the current setup. When the ENTER DESC screen is
entered, the description of the current setup is displayed as shown
below.
ENTER JOB DESC:
(LATCH01 )
While the keyswitch is in the PROG position, the description will
flash indicating that it can be changed. To change the
description, enter the new description over the old using the
numeric keypad for numbers and the up and down arrow keys for
letters. When selecting letters with the up and down arrow keys,
once the desired letter is selected use the right arrow key to move
to the next letter in the description. When finished entering the
description press the ENTER key.
2.5.1.3 STORE JOB
Once the job number and description have been set, the setup should
be stored to backup memory. When the STORE JOB option is selected
from the Store menu the screen below will be displayed.
STORE (YES/NO) ?
000025
To store the job to backup memory press the YES key, to abort this
operation press the NO key or the EXIT key. If a setup is already
stored in backup memory with the same job number, the screen below
will appear.
To store the current setup over the setup already in backup memory
press the YES key, otherwise press the NO key or the EXIT key.
Figure 4. Storing a Setup.
At the conclusion of a successful job storage operation, the screen
below will be displayed.
JOB STORAGE DONE.
PRESS EXIT.
NOTE: Although setups are stored in the System 1100 the
operator is encouraged to keep written records of stored
setups. These records will be useful in recovering
setups accidently lost by operator error or in the event
of memory failure within the System 1100.
2.5.2 RECALL
The Recall menu allows the user to recall previously stored setups
from backup memory into the current setup. The Recall menu is
shown below.
The ENTER JOB# screen allows the operator to directly enter the
number of job to recall. The ENTER JOB# screen is shown below.
ENTER JOB NUMBER TO
RECALL: ______
The six digit job number is entered by the operator using the
numeric keypad. When the operator presses the ENTER key after
keying in the job number, the System 1100 searches the backup
memory for the requested job and recalls it if it is found. If the
requested job is not present in backup memory a message indicating
so will be displayed.
2.5.2.1 SELECT JOB
The SELECT JOB screen allows the operator to search through a list
of all jobs stored in backup memory and select from that list a job
to recall. A typical SELECT JOB screen and list of jobs is shown
below.
The operator can use the up and down arrow keys to move through the
list of jobs. When the operator presses the ENTER key the System
1100 recalls the job currently shown on the LCD display.
numeric keypad. When the operator presses the ENTER key the System
1100 searches backup memory for the requested job and erases it if
it is found. If the requested job is not found a message
indicating so will be displayed.
2.5.3.2 SELECT JOB
The SELECT JOB screen allows the user to search through a list of
all jobs stored in backup memory and select a job for removing. A
typical SELECT JOB screen and list of jobs is shown below.

The operator can use the up and down arrow keys to move through the
list of jobs. When the operator presses the ENTER key the System
1100 erases from backup memory the job currently displayed on the
LCD display.
2.6 COUNTERS
The Counters menu provides access to the eight counters of the
System 1100. The counters can be divided into three types,
counters with presettable limits, alarm counters, and the Stroke
counter. Counters with presettable limits include the Part, Batch,
and Quality counters. Alarm counters include Machine Rating
Alarms, High Setpoints Alarms, Low Setpoint Alarms, and the Reverse
Setpoint Alarms counters.
When the Rate of Change automatic zeroing method is used (section
3.5.1) spurious counts can be produced if clutch or brake
engagement produces forces in the machine frame greater than the
zeroing threshold. The most accurate counts can be obtained when
the System 1100 is used with the optional zeroing cam (sections
2.8.5 and 3.5.2).
The Counters menu is shown below.
CNTRS $PART $
MENU $BATCH $9

STROKE
2.6.1 PART, BATCH, and QUALITY COUNTERS
The Part, Batch, and Quality counters have presettable limits.
These counters can be programmed to stop the production process
after a specified number of parts have been made. Only good parts
are counted, that is, parts whose forward tonnage is between the
high and low setpoints, and whose reverse tonnage is less than the
reverse setpoint. These counters operate in this way regardless of
BYPASS mode, or low or reverse limits being turned off.
For installations where the System 1100 stop circuit is connected
to the emergency stop of the press control, the System 1100
provides a top-stop delay timer (section 2.8.9). This timer is
capable of providing delays from 0 to 1 seconds to stop the machine
with the ram at the top of the stroke when a counter limit is
reached.
The Part counter is intended to count the total number of parts in
a run. The Batch counter is intended to count the number of parts
per batch. This counter is useful if part bins must be changed
several times during a part run. The Quality counter is used to
stop the production process at regular intervals for the operator
to perform part quality inspections.
The Part, Batch, and Quality counters all operate similarly and so
the examples discussed below apply to all of these counters. An
example Batch counter screen is shown below.
While the keyswitch is in the PROG position, the counter limit will
flash, indicating that it can be changed. This is done by entering
the new limit over the old using the numeric keypad, and then
pressing the ENTER key. The counter can be turned on or off while
in PROG mode by pressing the ON or OFF keys respectively. The
count value can be reset to zero while in PROG mode by pressing the
CLEAR key. The screen below will then appear.
CLEAR COUNTER?
(YES/NO)
Pressing the NO key will leave the count value in tact, while
pressing the YES key will reset the counter to zero. The example
counter screen is shown below after the counter has been cleared.
BATCH CNT: 0000000
(ON) LIMIT: 0123000
2.6.2 MACHINE RATING, HIGH, LOW and REVERSE ALARMS COUNTERS
The MACHINE RATING, HIGH, LOW, and REVERSE alarms counters count
the number of occurrences of each type of alarm. These counters do
not have limits, but should be checked regularly for excessive
numbers of alarms. All alarm counters operate similarly and so the
following discussion applies to all the alarm counters. An example
HIGH alarms counter screen is shown below.
HIGH-SET ALARMS:
0000027
While the keyswitch is in the PROG position alarm counters can be
reset to zero by pressing the CLEAR key. The screen below will
then prompt the operator for the access code.
The access code is entered by using the numeric keypad, then
pressing the ENTER key. If the correct access code is entered, the
screen below will then appear.
CLEAR COUNTER?
(YES/NO)
Pressing the NO or EXIT keys will leave the alarm counter value in
tact, while pressing the YES key will reset the alarm counter to
zero. The alarm counter screen below is shown after the counter
has been cleared.
HIGH-SET ALARMS:
0000000
2.6.3 STROKE COUNTER
The stroke counter is used to record the total number of machine
stokes since the System 1100 was installed on the machine. The
stroke counter screen is shown below.
STROKE COUNT:
0000145267
The stroke counter can be cleared by pressing the CLEAR key and
then entering a special access code. The stroke counter can be
cleared only while the keyswitch is in the PROG position. Since
the stroke counter is meant to count the total number of strokes
for the machine, it should never be cleared except in the case of
moving the System 1100 to a different machine.
The Errors menu provides the operator with the capability to view
a list of the currently active errors. Error codes are provided
with a short plain English explanation of error.
An example list of errors is shown below.
ERROR 05 - Channel
1 above threshold.9
ERROR 01 - Channel
1 will not zero.
ERROR 40 - End Of
Cycle cam failure.
ERROR 48 - Chan 1
high set too high.
Only one error is displayed at a time, with other errors available
by pressing the up and down arrow keys as indicated by the arrows
appearing at the right of the error screen. Errors can be cleared
