CODE 54 - OUTPUT 2 TERMINATION MODES (Cont'd)
[54 6] BOUNDARY MODE - When in boundary mode the Preset 2 Value serves
as the boundary point. When the Counter B Value is less than Preset 2, Output
2 is not activated (normal phase). When the Counter B Value is greater than or
equal to Preset 2, Output 2 is activated. If the Counter B Value were to drop
below Preset 2, Output 2 would then deactivate. For negative Preset points,
Output 2 is not activated when the Counter B Value is more positive that the
Preset 2 Value. When the count is more negative than or equal to Preset 2,
Output 2 is activated. If the count becomes more positive than Preset 2, Output
2 again deactivates. When the Preset 2 value is changed, Output 2 will
immediately go to the proper state. Upon power up, Output 2 will "remember"
its power down boundary condition and go to that state. Output 2 is set for
normal phase operation.
Programming Boundary mode will automatically select [56 1].
[54 -1]
[54 -2]
[54 -3] These modes are the same as above with the exception
[54 -4] that the output is set for reverse phase operation.

CODE 55 - TIMED OUTPUT 2 VALUE (GEMINI 4200 ONLY)
The Gemini 4200 has the capability of varying the Timed Output 2 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
"Programming the Presets, Scale Factors, Timed Outputs & Counter Load
Values" section for more details about entering. The timed output will be
terminated if the unit is manually reset.
Note: A Timed Output Value of zero cannot be programmed into the Gemini 4200.
If a value of 0 is entered into the display and the "E" key is pressed, the unit will
not enter the 0, but will stay in the data entry mode. If a new value is not entered,
it will time out and the unit will continue to use its previous setting.

CODE 56 - COUNTER B RESET MODES
The Gemini has six different Counter B reset modes. Note: For Gemini 4200
all reset to preset modes reset to preset 2. There are also two methods by which
manual reset can act on the counter (reset must be enabled, see function code 66
and dip switch set-up). The first is a "maintained" reset action, where the unit is
held at reset for as long as the reset terminal or reset button is activated. The
second is a "momentary" reset, in which the unit resets, when reset is activated,
and starts counting even though the reset terminal or reset button may still be
active. A "-" sign in front of the mode identifier indicates "momentary" reset
action, the absence of the "-" sign indicates "maintained" reset action.
In "Reset to Zero" modes the Output activates at the Preset Value. In "Reset to
Preset" modes, the Output activates at zero.
In the "Reset to Preset" modes, for proper operation, the counter normally
counts down. In the "Count with Inhibit" and "Separate Inputs" input response
modes, [43 1, or 4], the unit will automatically count down if a Reset to Preset
mode is selected. In the other input response modes, proper input phasing is
required for down counting. See "CODE 43 - INPUTS 1 & 2 RESPONSE
MODES" section for details.
The activation and de-activation response time for reset is 10 msec.
[56 1] MANUAL RESET TO ZERO (RTZ) - Manual reset to zero is
accomplished by pulling the "RST." terminal to "COMMON" or, if the front
panel reset is enabled, by pressing the front panel reset button. Reset is
"maintained".
[56 2] MANUAL RESET TO PRESET (RTP) - Manual reset to Preset is
accomplished by pulling the "RST." terminal to "COMMON" or, if the front
panel reset is enabled, by pressing the front panel reset button. Reset is
"maintained".
[56 3] AUTOMATIC RESET TO ZERO AFTER TIMED OUTPUT - The
counter automatically resets to zero when Timed Output ends. Manual reset is
"maintained" and will override automatic reset.
[56 4] AUTOMATIC RESET TO PRESET AFTER TIMED OUTPUT - The
counter automatically resets to Preset when Timed Output ends. Manual reset
is "maintained" and will override automatic reset.
