Red Lion GEMINI 42 - Manual (Page 15)

A reverse phase mode is available on the Gemini 4200. This refers to the
complementing of the logic state of the output. With normal phase operation,
when the display value reaches Preset 2, Output 2 will turn on. The reset
condition of Output 2 is output off. In reverse phase operation, Output 2 turns off
when the Preset 2 Value is reached. The reset condition of Output 2 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.
[54 1] TERMINATE AT OUTPUT 1 START - Output 2 will terminate when
Output 1 starts. Output 2 is set for normal phase operation.
[54 2] TERMINATE AT OUTPUT 1 END - Output 2 will terminate when
Output 1 ends. Output 2 is set for normal phase operation.
[54 3] TERMINATE AT MANUAL RESET - Output 2 activates when the rate
or count, whichever it is assigned to, 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 - Once Output 2 has been
activated, it will deactivate after the predetermined length of time (code
55) has expired. Manual reset will override the timed output and reset Output
2. When assigned to count or rate, Output 2 will activate when the display
value is greater than or equal to the Preset 2 Value. Output 2 is set for normal
phase operation.
[54 6] BOUNDARY MODE - When in boundary mode, the Preset 2 Value
serves as the boundary point. When the display value (count or rate) is less
than the Preset 2 Value, Output 2 is not activated (normal phase). When the
display value is greater than or equal to the Preset 2 Value, Output 2 is
activated. If the display value were to drop below Preset 2, Output 2 would
then deactivate. For negative Preset points, Output 2 is not activated when the
count value is more positive than the Preset 2 Value. When the count is more
negative than (only possible with counter) or equal to Preset 2, Output 2 is
activated. If the count becomes more positive than the Preset 2 Value, the
output again deactivates. When Output 2 is assigned to the counter and the
Preset 2 value is changed, Output 2 will immediately go to the proper state.
Upon power up, Output 2, if assigned to Counter B, 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], if
[51 1 or 2] is programmed.
[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.
The Timed Output 2 Value is used only when in Timed Output 2 Termination
mode, [54 5].
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.
