GENERAL DESCRIPTION

The Gemini 5200 is a multi-function dual rate indicator which can fulfill
almost any rate indication application. The unit can operate as two independent
rate indicators, with scaling, decimal point placement, and update times,
separately programmable for each channel. TheGemini5200alsohas three other
unit personalities. These modes feature a third display channel, C, which can
indicate the ratio, difference or draw between the A and B rate channels.

The programming of the rate channels and the calculated display is very
straightforward. Setting up Channel C only requires programming the desired
amount of resolution (for ratio and draw) and the appropriate decimal point
location. The Gemini 5200 simply takes the two rate values and mathematically
calculates display C accordingly.

The Gemini 5200 20 mA Current Loop Communications option provides the
capability of two-way serial communications between the Gemini 5200 and a
variety of equipment, such as a printer, remote terminal, programmable
controller, or host computer. The baud rate can be set to 300, 600, 1200, or 2400
baud. The format for transmitted and received data is 1 start bit, 7 data bits, 1
parity bit (odd), andastopbit.Whenutilizinganexternalpowersupply(30VDC
max.), up to sixteen units can be installed in the loop, each with an individual
address. When utilizing the Gemini’s20mAcurrentsource, up to seven unitscan
be installed in a loop. The Rate Values, Presets, and Scale Factor can be
interrogated or changed by sending the proper command codes and numerical
data (if required) to the unit. Various “Print Options” can be selected to
automatically interrogate the Rate Values, Presets, and Scale Factor by
activating the “Print Request” terminal or by sending a “Transmit Per Print
Option” (P) command.

The construction of the Gemini 5200 features a metal die-cast bezel, offering
maximum durability with a high quality die-cast appearance. The sealed front
panel meets NEMA 4/IP65 specifications for washdown and/or dust when
properly installed. Clamp type pressure plate terminals accept stripped #14
AWG wire without lugs.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.

Do notusethisunittodirectly command motors, valves, or other actuators not
equipped with safeguards. To do so, can be potentially harmful to persons or
equipment in the event of a fault to the unit.

PROGRAMMING THE GEMINI 5200

When your Gemini 5200 arrives from the factory, it has already been
programmed to function as a Dual Rate Indicator without the calculated C
display. It is programmed with the factory settings listed in the “Factory
Settings” section. If it is required to have the unit operate as a speed ratio, speed
difference or draw indicator, the Unit Personality function code can be changed
to do so.

The personality, functions, and modes are accessed by pressing the
appropriate keys as indicated by the embossed numbers above them. A function
is defined by a two-digit code which appears on the left side of the display. The
mode of that function is shown as a one-digit code on the right side of the display.
At times there will be a “-” sign modifier to the left of the mode.

Data for the Presets, Scale Factors and Timed Output Values are entered
differently. Each digit key controls the digit on the display directly above it.
Changing the digits can be done by repeatedly pressing the key beneath the digit
position you wish to changeor by holding the key down. As you hold it down,or
repetitively press it, the value of that digit will change cyclically, counting up to
9, then to 0, and thenup again. The 6 numbered keys correspond to thesix digits,
and the “+/-” key corresponds to polarity.

PROGRAMMING THE PERSONALITY

Entering function and mode is easily accomplished by
pressing the appropriate digit key. For the personality
function, you would enter 41 by pressing the front panel
keys, 4 and 1.

The digitsontheleftside of the display show the function
code; the digits on the right side show the current
programmed mode.

A newmode selection is made by enteringanew number.
On some of the entries, you have the option of a plus “+” or
minus “-” sign. In the cases where a “+” sign is required, no
sign will be displayed. If you do enter a “-” sign (using the
“+/-” key), a minus sign will be displayed in front of the
appropriate digit.

-2-

Pressing the “E” key finalizes the change. The display

will now show the rate value immediately.

If you do not press the “E” key, the change will not be
recorded. The displaywillremainintheprogrammingmode
for 15 seconds, and then return to normal operating mode
using the old function and mode settings.

Whenever the Unit Personality is changed, the factory settings will
automatically be loaded into the unit. The factory settings can also be
programmed into theunitbycallinguptheUnitPersonality,puttinga “-” in front
of the mode by pushing the “+/-” key, and entering it.

Refer to the “Initial Factory Configuration” section for more details.

PROGRAMMING THE PRESETS, SCALE FACTORS &
TIMED OUTPUT VALUES

The Presets and Scale Factor Values are commonly reprogrammed on a daily
basis. As such, single keystroke access has been provided on the front panel.

The Gemini 5200 has two Scale Factors, one for Rate
Display A,and one for Rate Display B. Pressing the “3”key
will call up the Scale Factor for the current rate value being
displayed (Rate A or Rate B).

To call up the “other” Scale Factor, the “+/-” key is first pushed to change the
display to the “other” value (Rate A or Rate B), then the “3” key is pushed to
display the Scale Factor for that value.

The internal unscaled rate valueismultipliedbythe Scale Factor Value,which

changes the displayed value accordingly.

To display the Preset 1 Value, the “1” key is pushed.

To change the value, the digits can be cycled through in
the same manner as discussed for the Scale Factors. The
Preset Values can range from -999999 to +999999.

The new valuewillbeentered when the“E”keyis pressed.

The Timed Output Values are changed by entering
two-digit function codes. After the code is entered, the
display will show the present Timed Output 1 or 2 Value in
seconds with two decimal place resolution. The Timed
Output Values can be set from .01 to 599.99 seconds.

Once the Scale Factor is displayed, changing the digits
can beaccomplished by repeatedly pressing the key beneath
the digit position you wish to change or by holding the key
down, allowing the digit to cycle.

The new valuewillbeentered when the“E”keyis pressed.

To changetheTimedOutput 1 Value, enter function code
53 and enter the new value by holding down or repeatedly
pressing the keybelowthedigit position youwishto change.

The newvalue willbe entered when the “E” key is pressed.
The display will immediately return to the rate value.

PROGRAMMING THE PRESETS, SCALE FACTORS &
TIMED OUTPUT VALUES [Cont’d]

Note: A Timed Output Value of zero cannot be programmed into the Gemini

5200. Ifa value of 0 is entered into the display, and the “E”key is pressed, the
unit will remain in data entry mode. If a new value is not entered, it will time
out and the unit will continue to use its previous setting.

As with the other functions, you must press “E” to record the changes. For the
data entry modes, if you do not press the“E” key, a time out of 5 seconds occurs,
and the display returns to operating mode without any changes to the value. The
only time any change will occur is when the “E” key is pressed.

OPERATOR ACCESSIBLE FUNCTIONS WITH
PROGRAMMING DISABLED

One of the important features of the Gemini 5200 is the ability to disable
programming. With this ability, accidental bumping of the keys or tampering by
unauthorized personnel canbe prevented.However, itmay benecessary toallow
reset and certain programming functions, such as Presets and Scale Factor
Values, to be changed indaily operation. The Gemini5200, through the use ofthe
“Operator Accessible Functions” modes, can enable these functions even when
the “PGM. DIS.” terminal is connected to “COMMON”.

The “Operator Accessible Functions” modes are programmed by entering a
two-digit function code (66) and the desired mode. Unlike other function codes,
the mode does not take effect immediately. The “PGM. DIS.” terminal must be
connected to “COMMON” in order for the Gemini to disable programming and
operate as per the mode programmed.

There are four basic “Operator Accessible Functions” Modes available. These
modes enable the following functions.

1. NO FUNCTIONS EXCEPT RESET ENABLED - In this mode, manual

reset is enabled, but none of the programming functions can be changed.

However, the functions can be interrogated.

2. PRESET PROGRAMMING AND RESET ENABLED - The entire front

panel is disabled with the exceptions of Preset programmability and manual

reset. All functions can be interrogated.

3. SCALE FACTOR PROGRAMMING AND RESET ENABLED - The

entire front panel is disabled with the exceptions of Scale Factor

programmability and manual reset. All functions can be interrogated.

4. SCALE FACTOR AND PRESET PROGRAMMING, AND RESET

ENABLED - The entire front panel is disabled with the exceptions of Scale

Factor and Preset programmability, and manual reset. All functions can be

interrogated.

All of these modes can be modified with the addition of a “-” sign. The minus
sign disables the manual reset, at the front panel and the remote reset (RST., not
RST.A) terminal, at the rear of the unit.

There is also a rear panel DIP switch which permits disabling of the front panel
reset button. This is independentof the rear terminal remote reset, and canbe used in
conjunction with any front panel disable mode. The combination of a manual and
remote reset inputs provides a high level of security without sacrificing flexibility.

DIAGNOSTICS, SELF-TEST, & “WATCHDOG” TIMER

The security of the Gemini5200 is further enhanced by its self-test diagnostic

and “watchdog” timer capabilities.

The diagnostics are concerned with the special, no power memory of the
Gemini 5200. Whenever the power is turned off, all pertinent function settings
and measurements are automatically saved. When power is restored, the
functions and data are re-instated. This allows you to program the unit once and
not have to re-program it until you wish to use it in another mode.

When the function codes and data are saved, computations are made with
these values.The resultof these computations is stored in the memory to serve as
a check against possible error. On powerup, the same computations are repeated
on the stored data. If the results do not agree with the stored results, a “P” will
appear onthe left side of thedisplay. If this occurs, refer to the “Troubleshooting
Guide” for directions.

The Gemini 5200 also contains a “watchdog” timer. In order to insure the
software is functioning properly, the program constantly monitors itself. If the
proper sequence and timing of internal events does not occur, an “E” will appear
on the left side of the display. If this occurs, refer tothe “Troubleshooting Guide”
for directions.

The final type of built-in check, is the front panel initiated self-test. It can be
performed at any time, even when the Gemini 5200 is running. It will not
interfere with the accumulation ofcounts orcontrol functions. A function codeof
“6”, “+/-” starts the test.At this time, whatever was displayed will disappear and
be replaced by a string of decimal points and the overflow indicator. Then the
display willshow a string of 9’s, then 8’setc., until a string of 0’s areshown. The
self-test will then turn off the overflow indicator and activate the minus “-” sign.
Then the unit shows an interlace pattern of -010101, then -212121, followed by

-232323 etc., until -898989 is reached. At this time the outputs can be tested by
pressing the “1” or “2” key. (The program disable pin must be disconnected in
order to allow activation of the outputs.) An automatic exit will take place after
six seconds or immediately if the Program Disable terminal is connected to
common. Normallength ofdisplay timefor eachof the patterns is approximately

0.5 sec. Rapidly pressing “E” during self-test can speed up the sequence.

-7-

INPUT CIRCUITRY & SET-UP

There are two independent input channels on the Gemini 5200. Various types
of sensoroutputs can be accommodated by appropriate DIP switch set-up.These
include: TTL or CMOS logic, current sinking, current sourcing, dry contact or
magnetic pickup.

Both Input Channels A and B consist of a logic input and a separate low level
magnetic pickup input. For a complete detailed description of input set-up, see
Appendix “A”.

OVERFLOW INDICATION

The Gemini5200 features anoverflow indicator (LED)which is locatedto the left
of the sixth digit and above the polarity annunciator. This LED will turn on if the
capacity of the display (6-digits) is exceeded or if the following conditions occur.

Upon power-up, the display willgo to zero, andthe overflow LED will turnon.
The overflow LED is turned on to indicate that the zero on the display is not a
measured value. The overflow LED will turn off after the Gemini 5200
completes its rate measurement. It will take 16 seconds if the rate is zero.

The overflow LED can also turn on when the rate input frequency exceeds the
maximum 3250 cps allowed for a rate update period of 16 sec. See Code 63 ­“Rate Minimum Update Time”.

-8-

PROGRAMMING THE GEMINI 5200 IN DUAL RATE WITHOUT DISPLAY C MODE

The rate indicators use a time interval method (1/tau) to calculate the rate
value. This method enables high resolution at all input rates. The unit counts
input pulses and after a programmable minimum update time has occurred, it
waits until the next count edge occurs, takes the elapsed time and number of
edges, and calculates the rate value. At slower rates, averaging can be
accomplished by programming the “Minimum Update Time”(0.5 sec.to 16 sec.)
for the desired response. Extensive scaling capabilities allow practically any
desired reading at very slow count rates.

In the Dual Rate, without Display Cmode, thetwo rateindicators operate in an
independent non-synchronized fashion. Input A serves as the inputto the Rate A
indicator and Input B serves as the input to the Rate B indicator. All modes are
independently selected for each rate channel.

CODE 41 - UNIT PERSONALITY

The unit personality mode is the first function code that is programmed. This
mode will determine the basic operational characteristics of the unit. This
programming section deals with the unit programmed as a Dual Rate Indicator
without Display C, mode 1. The “Programming The A/B, (A-B)/B, And A-B
Display C Modes” section covers programming of the Gemini 5200 whenin Unit
Personality modes 2, 3, and 4.

Once the Unit Personality mode is changed, the factory settings will
automatically be loaded into the unit’s memory. This provides a known starting
place. If at any point, it is desired to return to the factory settings for the current
mode, the unit personality is called up, a minus is put in front of the mode by
pressing the“+/-” key, and the “E” key is pushedto load the factory settings. The
factory settings are listed on page 5 and 6.

[41 1] DUAL RATE INDICATION - In this mode, the Gemini 5200 operates as

two independent rate indicators.

[41 2] DUAL RATE WITH A/B DISPLAYC-Inthis unit personality, the

Gemini 5200 operates as a dual rate indicator with an A/B display C function.

See “Programming The A/B, (A-B)/B,And A-B Display CModes” section for

programming details.

[41 3] DUAL RATE WITH A-B DISPLAYC-Inthis unit personality, the

Gemini 5200 operates as a dual rate indicator with an (A-B) Display C
function. See “Programming The A/B, (A-B)/B, And A-B Display C Modes”
section for programming details.

[41 4] DUAL RATE WITH (A-B)/B DISPLAYC-Inthis unit personality, the

Gemini 5200 operates as a dual rate indicator with an (A-B)/B Display C
function. See “Programming The A/B, (A-B)/B, And A-B Display C Modes”
section for programming details.

CODE 42 - RESET KEY & TERMINAL ACTUATION MODES

The Reset Button & Terminal Actuation Modes controls the effect that the
reset button and terminal have on the two display channels. Resetting will not
affect the rate displays or update period in any manner. Reset only affects the
output(s) associated with the rate channels.

There is a separate “Rst A” terminal provided which makes it possible to
independently reset both the Rate A and B Outputs.

CODE 43 - RATE B CONVERSION FACTOR

The Rate B Conversion Factor is used to convert Display B to indicate rate in
the desired time unit. See Appendix “F” - Scaling For Rate And Display C.

[43 1] Rate Per Second (x1)
[43 2] Rate Per Minute (x60)
[43 3] Rate Per Hour (x3600)

CODE 44 - RATE B MINIMUM/MAXIMUM UPDATE TIME

The determination of the rate value usesa method in which theelapsed time is
measured between the first and last pulse of the update period. The minimum
update time is the shortest the time period can be. Once the minimumupdate time
has expired, the unit will end the measurement period when the next negative
going count edgeoccurs. Ifthe unitdoes notreceive thenext negative count edge
within the maximum update time at the start of the measurement period, the unit
will end the time period and the rate display will go to zero. At very slow count
rates the update time period will be the actual period of one count cycle.

[44 1] 0.5 Sec. minimum/1 Sec. maximum

[44 6] 16 Secs. minimum/32 Secs. maximum (max. rate = 3250 cps)

CODE 45 - RATE B SCALE MULTIPLIER

The Rate B Scale Multiplier is used in conjunction with the Rate Scale Factor
B and Rate B Conversion Factor to scale the actual signal input to obtain the
desired reading.

[45 1] x 1000
[45 2] x 100
[45 3] x10
[45 4] x1
[45 5] x 0.1
[45 6] x 0.01

CODE 46 - RATE B DECIMAL POINT & LEADING ZERO
BLANKING

There are six basic modes of decimal point placementfor the Rate B indicator
of the Gemini 5200. The decimal point is placed to the right of the display digit
that corresponds to the mode identifier. (The right most decimal point, digit 1, is
never turned on.) A “-” sign in front of the mode identifier will inhibit leading
zero blanking. The absence of a “-” sign will enable leading zero blanking.

CODE 51 - OUTPUT ASSIGNMENT

The outputs of the Gemini 5200 can be assigned to either the Rate A or Rate B

channel or one to each.

The Gemini 5200 has a Preset tracking feature which allows Preset 1 to track
Preset 2.If Presettracking isprogrammed, wheneverthe Preset2 valueis changed,
the Preset 1 value will also change to maintain the same offset. For example, if
Preset 1 is 100 and Preset 2 is 200, changing Preset 2 to 300 will automatically
change Preset1 to200, maintainingthe same100 unitoffset. Inorder to change the
amount of offset, the Preset 1 value is changed. The Preset tracking feature is
programmed by adding a “-” modifier in front of the desired mode.

Note: When Preset tracking is enabled, before changing Preset 2 via serial

communications, the Preset 2 value must be interrogated in order to establish

the Preset 1 value.

CODE 52 - OUTPUT 1 TERMINATION MODES

The Gemini 5200 has four “Output 1 termination Modes” which control the
way Output 1 will terminate or reset. In all modes, Output 1 will terminate
immediately when the channel to which it is assigned is manually reset.

A reverse phase mode is available on the Gemini 5200. This refers to the
complementing of the logic state of Output 1. With normal phase operation,
when the display value reaches Preset 1, Output 1 will turn on. The reset
condition ofOutput 1 is output off. In reversephase operation, Output 1 turns off
when Preset 1 is reached. The reset condition of Output 1 is output on. (Note: The
state of the relay, if used, is also reversed.) A “-” sign in front of the mode
identifier will provide for reverse phase operation. The absence of a “-” sign will
indicate normal phase operation.

[52 3] TERMINATE AT MANUALRESET -Output 1 activates whenthe rateis

greater than or equal to the Preset 1 value. In this mode, once Output 1 is

activated, it does not deactivate until the moment a manual reset occurs.

Output 1 is set for normal phase operation.

[52 4] TERMINATE AT MANUAL RESET END - This mode is like the

preceding, except Output 1 deactivates when reset ends. Output 1 is set for

normal phase operation.

[52 5] TERMINATE AFTER TIMED OUTPUT1-Ifboth outputs are assigned to

the same rate channel [51 2,3], Output 1 will activate when the rate is below or

equal tothe Preset 1 value. Ifeach output is assigned toa different channel [51 1],

Output 1 will activate whenthe rateis greaterthan or equal to the Preset1 Value.

Output 1 will terminate after the “Timed Output 1 Value” if the timed output

value is less than the update time of the rate channel. If the timed output value is

greater than the update time,the outputwill appear to be latched on,deactivating

when therate drops below the Preset[51 1], or above the Preset [51 2,3] andthe

output time expires. Output 1 is set for normal phase operation.

[52 6] BOUNDARY MODE - When in boundary mode, the Preset 1 Value serves

as the boundary point. When the rate value is less than Preset 1, Output 1 is not

activated (normal phase). When the rate value is greater than or equal to the

Preset, Output 1 is activated. If the display value were to drop below Preset 1,

Output 1 would then deactivate. Output 1 is set for normal phase operation.

[52 -3]
[52 -4] These modes are the same as above with the exception
[52 -5] that Output 1 is set for reverse phase operation.
[52 -6]

CODE 53 - TIMED OUTPUT 1 VALUE

The Gemini 5200 has the capability of varying the Timed Output 1 value from

0.01 second to 599.99 seconds. When the code is entered, instead of a single mode
identifier digit being displayed, six digits will be shown.Refer to the“Programming
The Presets, Scale Factors, And Timed Output Values” section for more details
about entering. The timed output will be terminated if the unit is manually reset.

The Timed Output 1 Value is used only when in timed output termination

mode, [52 5].

Note: A Timed Output Value of zero cannot be programmed intothe Gemini 5200.

If avalue of 0 is enteredinto the display and the “E” key is pressed, the unit will
not enterthe 0, but will stay in the data entrymode. Ifa new value is not entered,
it will time out and the unit will continue to use its previous setting.

CODE 54 - OUTPUT 2 TERMINATION MODES

The Gemini 5200 has four “Output 2 termination Modes” which control the
way Output 2 will terminate or reset. In all modes Output 2 will terminate
immediately when the channel to which it is assigned is manually reset.

A reverse phase mode is available on the Gemini 5200. This refers to the
complementing of the logic state of Output 2. With normal phase operation,
when the display value reaches Preset 2, Output 2 will turn on. The reset
condition ofOutput 2 is output off. In reversephase operation, Output 2 turns off
when Preset 2 is reached.

The reset condition of Output2 is output on. (Note:The stateof the relay, ifused,
is also reversed.) A “-” sign in front of the mode identifier will provide for reverse
phase operation. The absence of a “-” sign will indicate normal phase operation.

activated, it does not deactivate until the moment a manual reset occurs.
Output 2 is set for normal phase operation.

[54 4] TERMINATE AT MANUAL RESET END - This mode is like the

preceding, except Output 2 deactivates when reset ends. Output 2 is set for
normal phase operation.

[54 5] TERMINATE AFTER TIMED OUTPUT 2 - Output 2 will activate when

the rate isgreater thanor equal to thePreset 2 Value andwill terminate after the
“Timed Output 2 Value” expires. This will occur every update time period for
which the above condition istrue. Ifthe output duration time isgreater thanthe
update time, Output 2 will appear to be latched on, deactivating when the rate
drops below the Preset and the output time expires. Output 2 is set for normal
phase operation.

[54 6] BOUNDARY MODE -When in boundary mode, the Preset2 Value serves

as the boundarypoint. Whenthe ratevalue isless than Preset 2, Output 2 is not
activated (normal phase). When the rate value is greater than or equal to Preset
2, Output 2 is activated. If the display value were to drop below Preset 2,
Output 2 would then deactivate. Output 2 is set for normal phase operation.

[54 -3]

CODE 55 - TIMED OUTPUT 2 VALUE

The Gemini 5200 has the capability of varying the timed output from 0.01
second to 599.99 seconds. When the code is entered, instead of a single mode
identifier digitbeing displayed, six digits willbe shown. Refer to “Programming
The Presets, Scale Factors, And Timed Output Values” section for more details
about entering. TimedOutput 2will be terminated ifthe unit is manuallyreset.

The Timed Output 2 Value is used only when in timed output termination
mode, [54 5].

Note: A Timed Output Value of zero cannot be programmed intothe Gemini 5200.

If avalue of 0 is enteredinto the display and the “E” key is pressed, the unit will
not enterthe 0, but will stay in the data entrymode. Ifa new value is not entered,
it will time out and the unit will continue to use its previous setting.

CODE 56 - RATE B RIGHT HAND DUMMY ZEROS

Dummy zeros can be usedto alleviatedisplay fluctuationsdue to an unstable input
signal. Thesezeros effectively movesignificant digits to the left. Therefore, a normal
rate display of 1 could be shown as a 10, 100, or 1000. Using the dummy zeros will
make it necessary to adjust the scaling if they were not considered before.

CODE 63 - RATE A MINIMUM/MAXIMUM UPDATE TIME

The determination of the rate value usesa method in which theelapsed time is
measured between the first and last pulse of the update period. The minimum
update time is the shortest the time period can be. Once the minimumupdate time
has expired, the unit will end the measurement period when the next negative
going count edgeoccurs. Ifthe unitdoes notreceive thenext negative count edge
within the maximum update time at the start of the measurement period, the unit
will end the time period and the rate display will go to zero. At very slow count
rates, the update time period will be the actual period of one count cycle.

CODE 64 - RATE A SCALE MULTIPLIER

The Rate A Scale Multiplier is used in conjunction with the Rate Scale Factor
A and Rate A Conversion Factor to scale the actual signal input to obtain the
desired reading.

There are six basic modes of decimal point placement for the Rate A indicator
of the Gemini 5200. The decimal point is placed to the right of the display digit
that corresponds to the mode identifier. (The right most decimal point, digit 1, is
never turned on.) A “-” sign in front of the mode identifier will inhibit leading
zero blanking. The absence of a “-” sign will enable leading zero blanking.

CODE 66 - “OPERATOR ACCESSIBLE FUNCTIONS” MODES

The Gemini 5200 has four basic levels of “Operator Accessible Functions”.
Each of these levels can be modified to enable or disable manual reset. When the
“PGM. DIS.” (program disable) terminal is connected to “COMMON”, access
to all functions is disabled except for those listed below which will remain
enabled. Allof thefunction codes and parameters can be interrogated, regardless
of the “Operator Accessible Functions” mode selected.

A “-” sign in front of the mode identifier will disable the front panel Reset
button and the “RST.” terminal.

Note: The front panel reset button can be independently disabled by using the

disable reset DIP switch.

[66 1] NO FUNCTIONS ENABLED EXCEPT RESET - In this mode, manual

reset is enabled, but none of the programming functions can be changed.
[66 2] PRESET PROGRAMMING AND RESET ENABLED - In this mode,

manual reset and the programming of the Preset Values are enabled.
[66 3] SCALE FACTOR PROGRAMMING AND RESET ENABLED - In this

mode, manual reset and the programming of the Scale Factors are enabled.

PRESET VALUES

Whenever the display value equals the Preset 1 or 2 Value, an output action
will occur. This action depends on the previously programmed modes. The
Preset Values may vary from -999,999 to 999,999. Refer to “Programming The
Presets, Scale Factors, And Timed Output Values” section for instructions on
entering the Preset Values.

“1” - PRESET 1 VALUE
“2” - PRESET 2 VALUE

SCALE FACTORSA&B

“3” SCALE FACTOR - The Scale Factor, for whichever Value (Rate A or B)
is currently being displayed, is accessed by pressing the “3” key. To access the
Scale Factor of the “other” rate display value, the “+/-” key would be pushed (to
change the display to the other value), then the “3” key would be pushed. The
actual rate (in pps) is multiplied by the Scale Factor, Scale Multiplier, and Rate
Conversion factor to obtain the desired display reading. The Scale Factor is used
primarily for conversion from existing pulses per unit of measure to the required
displayed units. This includes conversionfrom different units of measure(i.e feet
to meters, etc.). The Scale Factor Values may range from 0.0001 to 5.9999. Refer
to “Programming The Presets, Scale Factors, And Timed Output Values” section
for instructions on entering the Scale Factor Values.

PROGRAMMING THE A/B, (A-B)/B, AND A-B DISPLAY C MODES

This section will deal with the programmingand operationof the Gemini 5200
in the modes which includeDisplay C,[41 2,3,4]. Since all threedisplay Cmodes
are very similar in operation, they will all be covered in one section.

BASIC OPERATION

In all of the display C modes, the Gemini 5200 performs a mathematical
calculation using Rate channelsA&Btoobtain the Display C value.

The tworate indicators, use a time interval method (1/tau) to calculate the rate
value. This method enables high resolution at all input rates. The unit counts
input pulses and after a programmable minimum update time has occurred, it
waits until the next count edge occurs, takes the elapsed time and number of
edges, and calculates the rate value. At slower rates, averaging can be
accomplished by programming the “Minimum Update Time”(0.5 sec.to 16 sec.)
for the desired response.

When operatingin anyof the three modes which utilize display C, the two rate
indicators will synchronize themselves in order to obtain an accurate display C
reading. The Gemini 5200 will determine which channel is running at the slower
rate, andit will use that channel to synchronize the other channel. This is done so
that both time measurement windows are as close as possible. Because it is
necessary to keep the measurement windows the same, there is only one Rate
Minimum Update Time setting. The slower channel will determine the update
time for the other rate channel and Display C.

If one rate input signal drops out before the update period has completed, that
channel will go to zero after the maximum update time has expired. The channel
will then continually time-out according to the maximum update time that was
selected in Code 63, until a rate signal again appears on its input. After the first
time-out, the other channel, which still has a rate signal on its input, will then
begin to operate in a non-synchronous manner, updating according to the
“Minimum Update Time” and its input frequency. It will not synchronize with
the channel that timed-out, and has an update period of 16 seconds.

The Display C channel, however, will only update according to the
maximum update time because it is calculated based on both of the rate
channels. The rate channels will again synchronize when both channels have a
rate signal on their inputs.

CODE 41 - UNIT PERSONALITY

The unit personality mode is the first function code that is programmed. This
mode will determine the basic operational characteristics of the unit. This
programming section deals with the unit personality programmed as a Dual Rate
Indicator with Display C, modes 2, 3, or 4. A separate section, “Programming
The Gemini 5200 In Dual Rate Without Display C Mode” goes over the
programming of the Gemini 5200 when programmed in mode 1.

Whenever the Unit Personality mode is changed, the factory settings will
automatically be loaded into the unit’s memory. This provides a known starting
place. If at any point, it is desired to return to the factory settings for the current
personality, the unit personality iscalled up, a minus isput infront of the modeby
pressing the “+/-” key, and the “E” key is pushed to load the factory settings.

[41 1] DUALRATE INDICATION - In this UnitPersonality, theGemini 5200

operates as two independent rate indicators. See “Programming The Gemini

5200 In DualRate WithoutDisplay C Mode” sectionfor programming details.
[41 2] DUAL RATE WITH A/B DISPLAY C - In this unit personality, the

Gemini 5200 operates as a dual rate indicator with an A/B (Speed Ratio)

Display C function.

[41 3] DUAL RATE WITH A-B DISPLAY C - In this unit personality, the

Gemini 5200 operates as a dual rate indicator with anA-B (Speed Difference)

Display C function.

[41 4] DUALRATE WITH(A-B)/B DISPLAYC - In this unit personality, the

Gemini 5200 operates as a dual rate indicator with an (A-B)/B (Speed Draw)

CODE 51 - OUTPUT ASSIGNMENT

The outputs of the Gemini 5200 can be assigned to the Rate A, Rate B, or the
Display C channel.

The Gemini 5200 has a Preset tracking feature which allows Preset 1 to track
Preset 2. If Preset tracking is programmed, whenever the Preset 2 value is changed,
the Preset1 valuewill alsochange to maintain the same offset. For example, if Preset
1 is 100 and Preset 2 is 200, changing Preset 2 to 300 will automatically change
Preset 1 to 200, maintaining the same 100 unit offset. In order to change the amount
of offset,the Preset 1 value is changed. The Preset tracking feature is programmedby
adding a “-” modifier in front of the desired mode.

CODE 52 - OUTPUT 1 TERMINATION MODES

The Gemini 5200 has four “Output 1 termination Modes” which control the
way Output 1 will terminate or reset. In all modes, Output 1 will terminate
immediately when the channel to which it is assigned is manually reset.

A reverse phase mode is available on the Gemini 5200. This refers to the
complementing of the logic state of Output 1. With normal phase operation,
when the display value reaches Preset 1, Output 1 will turn on. The reset
condition ofOutput 1 is output off. In reversephase operation, Output 1 turns off
when Preset 1 is reached. The reset condition of Output 1 is output on. (Note: The
state of the relay, if used, is also reversed.) A “-” sign in front of the mode
identifier will provide for reverse phase operation. The absence of a “-” sign will
indicate normal phase operation.

[52 3] TERMINATE AT MANUAL RESET - Output 1 activates when the rate

or display valueis greaterthan or equal tothe Preset 1 value. Inthis mode, once

Output 1 is activated, it does not deactivate until the moment a reset occurs.

Output 1 is set for normal phase operation.

[52 4] TERMINATE AT MANUAL RESET END - This mode is like the

preceding, except Output 1 deactivates when reset ends. Output 1 is set for

normal phase operation.

[52 5] TERMINATE AFTER TIMED OUTPUT1-Ifboth outputs are assigned

to the same channel [51 2,3,6], Output 1 will activate when the rate or display
value is below or equal to the Preset 1 value. If each output is assigned to a
different channel [51 1,4,5], Output 1 will activate when the rate or display
value is greater than or equal to the Preset 1 Value.
Output 1 will terminate after the “Timed Output 1 Value” if the Timed Output
Value is less than the update time of the rate or display channel. If the Timed
Output 1 Value is greater than the programmed update time, Output 1 will
appear to be latched on, deactivating when the rate or display value drops
below the Preset [51 1,4,5], or above the Preset [51 2,3,6] and the output time
expires. Output 1 is set for normal phase operation.

[52 6] BOUNDARY MODE - When in boundary mode, the Preset 1 Value

serves asthe boundary point. When the rate or display valueis less than Preset
1, Output 1 is not activated (normal phase). When the rate or display value is
greater than or equal toPreset 1, Output 1 isactivated. If the display valuewere
to drop below Preset 1, Output 1 would then deactivate. Output 1 is set for
normal phase operation.

The Timed Output 1 Value is used only when in timed output termination
mode, [52 5].

Note: A Timed Output Value of zero cannot be programmed intothe Gemini 5200.

If avalue of 0 is enteredinto the display and the “E” key is pressed, the unit will

CODE 54 - OUTPUT 2 TERMINATION MODES

The Gemini 5200 has four “Output 2 termination Modes” which control the
way Output 2 will terminate or reset. In all modes, Output 2 will terminate
immediately when the channel to which it is assigned to is manually reset.

A reverse phase mode is available on the Gemini 5200. This refers to the

identifier will provide for reverse phase operation. The absence of a “-” sign will
indicate normal phase operation.

[54 3] TERMINATE AT MANUALRESET -Output 2 activates when therate or

display value is greater than or equal to the Preset 2 value. In this mode, once

Output 2 is activated, it does not deactivate until the moment a reset occurs.

Output 2 is set for normal phase operation.

[54 4] TERMINATE AT MANUAL RESET END - This mode is like the

preceding, except Output 2 deactivates when reset ends. Output 2 is set for

normal phase operation.

[54 5] TERMINATE AFTER TIMED OUTPUT 2 - Output 2 will activate when

the rate or display value is greater than or equal to the Preset 2 Value and will

terminate after the “Timed Output 2 Value” expires. This will occur every

update time period for which the above condition is true. If the Output 2

duration time is greater than the display update time, the output will appear to

be latched on, deactivating when the rate or displayvalue dropsbelow Preset2

and the output time expires. Output 2 is set for normal phase operation.

[54 6] BOUNDARY MODE - When in boundary mode, the Preset 2 Value

serves asthe boundary point. When the rate or display valueis less than Preset

2, Output 2 is not activated (normal phase). When the rate or display value is

greater than or equal toPreset 2, Output 2 isactivated. If the display valuewere

to drop below Preset 2, Output 2 would then deactivate. Output 2 is set for

normal phase operation.

CODE 55 - TIMED OUTPUT 2 VALUE

The Gemini 5200 has the capability of varying theTimed Output2 Value from

0.01 second to 599.99 seconds. When the code is entered, instead of a single
