SCALING FOR COUNTER B
Counter B is used to control the length of the cardboard insert. The display
reading for Counter B is to be in hundredths of an inch. The “Number of Pulses”
per 1200 “Display Units” (1200 hundredths of an inch = 1 foot) is 1200. It can
easily be seen that 1 pulse will provide for 1 “Display Unit” of indication (1
hundredth of an inch). The Gemini 4200 can therefore be left at its Scale Factor B
and Scale Multiplier B factory settings of 1. The “Counter A & B Number of
Count Edges”, code 44, is also left at the factor set value of 1.
STEP BY STEP PROGRAMMING OF THE GEMINI 4200
STEP 1 - Enter code 41 (Unit Personality). Select and enter mode 2 to set the Unit
Personality to Dual Counter.
STEP 2 - Enter code 42 (“Reset Button & Terminal Actuation Mode”). Select
and enter mode 2 so reset will reset Counter B. This will allow Counter B to be
reset when the front panel reset button is pushed.
STEP 3 - Enter code 43 (“Inputs 1 & 2 Response Modes”). Select and enter mode 4
for Separate Inputs mode (Input 1 = Counter A input, Input 2 = Counter B input).
STEP 4 - Enter code 44 (“Counters A & B Number of Count Edges”). Select and
enter mode 1 for single edge counting.
STEP 5 - Enter code 45 (Counter B Scale Multiplier). Select and enter mode 1 for
a scale multiplier of 1.
STEP 6 - Enter code 46 (Counter B Decimal Point & Lead Zero Blanking).
Select and enter mode 3 for a decimal point in the hundredths location.
STEP 7 - Enter code 51 (Output Assignment). Select and enter mode (-)2 to
assign both outputs to Counter B and enable preset tracking.
STEP 8 - Enter code 52 (Output 1 Termination Modes). Select and enter mode 2
for termination at Output 2 end.
Note: The Timed Output 1 Value, code 53 is not used in this application.
STEP 9 - Enter code 54 (Output 2 Termination Modes). Select and enter mode 5
for timed output operation.
STEP 10 - Enter code 55 (Timed Output 2 Value). Change the value to 0.50 and
enter.
STEP 11 - Enter code 56 (Counter B Reset Modes). Select and enter mode 5 for
Automatic Reset to Zero at Preset 2.
Note: Code 61 (Counter A Reset Modes) was automatically selected to mode
1, Reset to Zero, when mode [51 2] was programmed.
STEP 12 - Enter code 64 (Counter A Scale Multiplier). Select and enter mode 1
for a scale multiplier of 1.
STEP 13 - Enter code 65 (Counter A Decimal Point & Leading Zero Blanking).
Select and enter mode 1 for no decimal point.
STEP 14 - Enter code 66 (Operator Accessible Functions Modes). Select and
enter mode 2 for Preset programming and reset enabled. When the
“PGM.DIS.” terminal is connected to “COMM.”, the only changes that will be
possible are resetting the unit and changing the Preset.
The Gemini 4200 in now fully programmed. Jumper the “PGM.DIS.” terminal
to “COMM.” to prevent accidental program changes and to enable the “Operator
Accessible Functions”.
