CODE 46 - COUNTER B DECIMAL POINT & LEADING ZERO
BLANKING
There are six basic modes of decimal point placement for Counter B of the
Gemini. 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 output of the Gemini 4100 is assigned to Counter B, or for the Gemini
4200 one can be assigned to Counter B and the other to Counter A. When both are
assigned to Counter B, the Gemini will automatically configure the Counter A
Reset Mode to Reset to Zero, [61 1].
The Gemini 4200 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 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 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
programmed by adding a “-” modifier in front of the desired mode.
[51 1] OUTPUT 1 ASSIGNED TO COUNTER A, OUTPUT 2 ASSIGNED TO
COUNTER B (Gemini 4200 Only)
[51 2] OUTPUT 1 & 2 ASSIGNED TO COUNTER (B)
CODE 52 - OUTPUT 1 TERMINATION MODES
The Gemini has six “Output Termination Modes”, which control the way
Output 1 will terminate or reset. In all modes, Output 1 will terminate
immediately when the counter to which it is assigned is manually reset.
Output 1 termination modes 1 & 2 are available only with a Gemini 4200 and
when both outputs are assigned to Counter B, [51 2].
A reverse phase mode is available on the Gemini. This refers to the
complementing of the logic state of the output. With normal phase operation,
when the display value reaches the Preset 1, Output 1 will turn on. The reset
condition of Output 1 is output off. In reverse phase operation, the Output 1 turns
off when the 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 1] TERMINATE AT OUTPUT 2 START - Output 1 will terminate when
Output 2 starts. Output 1 is set for normal phase operation. (Gemini 4200 Only)
[52 2] TERMINATE AT OUTPUT 2 END - Output 1 will terminate when
Output 2 ends. Output 1 is set for normal phase operation. (Gemini 4200 Only)
[52 3] TERMINATE AT MANUAL RESET - Output 1 activates when the
Counter A or Counter B value, whichever it is assigned to, is 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 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.
