Red Lion GEMINI 2 - Manual (Page 12)

CODE 51 - RESET MODES (Cont’d)
[51 3] AUTOMATIC RESET TO ZERO AFTER OUTPUT TIME DELAY -
The counter resets to zero when the output time delay ends. Manual reset
is “maintained” and will override automatic reset.
[51 4] AUTOMATIC RESET TO PRESET AFTER OUTPUT TIME DELAY -
The counter resets to the preset value when the output time delay ends.
Manual reset is “maintained” and will override automatic reset.
[51 5] AUTOMATIC RESET TO ZERO AT THE BEGINNING OF THE
OUTPUT TIME DELAY - When in this reset mode, the unit will
automatically reset to zero at the beginning of the output time delay (when
the preset point is reached). For the Gemini 2000, the output 1 and output 2
time delays must be shorter than the time required for the counter to count
to the preset 2 value. Otherwise, the output(s) will appear to be latched on.
Manual reset is “maintained” and will override automatic reset.
[51 6] AUTOMATIC RESET TO PRESET AT THE BEGINNING OF THE
OUTPUT TIME DELAY - In this reset mode, the unit will automatically
reset to preset at the beginning of the output time delay (when zero is
reached). For the Gemini 2000, the output 1 and output 2 time delay must
be shorter than the time required for the counter to count to zero.
Otherwise, the outputs will appear to be latched on. Manual reset is
“maintained” and will override automatic reset.

[51 -3] These modes are the same as above with the exception
[51 -4] that Reset is set for “momentary” operation.

CODE 52 - OUTPUT 1 TERMINATION MODES
The Gemini has six Output Termination Modes. They are: Terminate at
Output 2 Start; Terminate at Output 2 End; Terminate at Manual Reset;
Terminate at Manual Reset End; Terminate After Time Delay; and Boundary.
A Reverse Phase Option is available on the Gemini. This refers to
complementing the logic state of the output. With normal phase operation, when
the count reaches preset 1 the output will turn on. The reset condition of the
output is output off. In reverse phase operation, the output turns off when the
preset is reached. The reset condition of the output 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 give
normal phase operation.
In all modes except boundary, when the unit is powered up, the relays or
outputs will be turned off. This is done to help prevent a hazardous situation from
occurring. If other than boundary or time delay operation is selected, the unit
should be reset upon power up.
[52 1] TERMINATE AT OUTPUT 2 START - Output 1 will terminate when
Output 2 starts. (Gemini 2000 only)
[52 2] TERMINATE AT OUTPUT 2 END - Output 1 will terminate when
Output 2 terminates. (Gemini 2000 only)
[52 3] TERMINATE AT MANUAL RESET - In this mode, output 1, once
activated, does not deactivate until the moment a reset occurs. The reset can be
from the front panel button or from the remote reset terminal at the rear of the
unit. The output is set for normal phase operation.
[52 4] TERMINATE AT MANUAL RESET END - This mode is like the
preceding output mode, except output 1 deactivates when the reset ends. The
output is set for normal phase operation.
[52 5] TERMINATE AFTER OUTPUT 1 TIME DELAY - Once output 1 has
been activated, it will deactivate after the predetermined length of output 1
time delay has expired. Manual reset, by either the front panel button or the
reset terminal, will override the output 1 time delay and reset the output. The
output is set for normal phase operation.
[52 6] BOUNDARY MODE - This mode can be used when the unit is
functioning as a counter, but is more applicable to the rate indicator mode.
When in boundary mode, the preset 1 value serves as the boundary point.
When the count is less than the preset, the output is not activated (normal
phase). When the count is greater than or equal to the preset, the output is
activated. If the count value were to drop below preset, the output would again
deactivate. For negative preset points, the output is not activated when the
count value is more positive than the preset value. When the count is more
negative than or equal to the preset, the output is activated. If the count
becomes more positive than the preset, the output again deactivates. Upon
power up, the output will “remember” its power down boundary condition
and go to that state. The output is set for normal phase operation.
