NO MODE

If a User Input terminal or a Function key is activated it will be ignored.

MAINTAINED RESET (MNT RST)

Maintained reset has four selectable options, in which any or all can be

selected in the edit menu by selecting YES or NO using the UP and DOWN
arrow keys. When using the maintained reset with a small preset value, the
Inhibit input should be used with maintained reset, if the signal is present at
the input when the reset is activated.

RATE:

Resets the measurement period. The rate display value will be the

last reading obtained before the reset. The next reading will occur after
the release of the reset and the expiration of the measurement period.
The Rate display will not reset to zero.

PEAK:

Resets the peak value to the current rate value.

VALLEY:

Resets the valley value to the current rate value.

COUNT:

Resets the count value to the programmed reset action.

With Maintained reset, the value is held reset as long as the User
Input or Function key is active. The unit will start updating the
appropriate display when no longer in reset. Maintained reset is
level sensitive and overrides an automatic reset mode.

MOMENTARY RESET (MOM RST)

Momentary reset has the same four selectable options as Maintained Reset.

With Momentary reset, the value resets when the user input or function key is
activated. The value will start updating (counting) after the reset action has
occurred, even if the user input or function key is still active. Momentary
reset is negative edge sensitive and overrides an automatic reset mode.

RESET OUTPUT (RST OUT)

The operator can select to have Output 1 and/or Output 2 reset. If the output

is active, it will reset to its inactive state when the user input or function key is
activated. This is a momentary reset.
Note: The inactive state of an output can be ON or OFF depending on what

the Phase is programmed for in the Program Outputs Module.

SET OUTPUT (SET OUT)

The operator can select to have Output 1 and/or Output 2 set. If the output is

inactive, it will go (set) to its active state when the user input or function key is
activated. If an output is programmed with a time delay and this user input is
activated, the output will NOT latch, but will time out after the time delay
value expires. This is a momentary reset.
Note: The active state of an output can be ON or OFF depending on what the

Phase is programmed for in the Program Outputs Module.

VIEW/FREEZE DISPLAY (VIEW DS1)

When a User Input is activated, an indication display will be viewed and

the numeric value for that display will be held. If the operator is in the main
display loop, the unit will advance to the indication display to be viewed. If
more than one user input is used for this option, the input with the highest
priority will be the only one that will hold (freeze) the display. Also, it will be
the only input, when activated, that will advance to the indication display
from the main display loop. Any other user input programmed, will only
advance in the indication display loop. DS1 selects display 1, DS2 display 2,
DS3 display 3, and DS4 display 4. The values that are viewed/frozen on the
display are determined by what is selected in the Program Displays Module.
Note: If an external and a front panel user input are both selected for this

option, the display will be viewed but the numeric value will NOT freeze
when either user input is activated.

CHANGE DISPLAY (CHG DSP)

In the indication display loop, when a user input is activated, the indication

display will toggle to the next indication display. The change display is a
momentary action.

COUNTER LOAD (CNT LD)

When a user input is activated, the count value is reset to the counter load

value regardless of the reset action mode. The counter load is a maintained
action.

PRINT REQUEST (PRINT RQ)

When a user input is activated, the unit transmits all the information

selected in the Print Options Module via the RS485 serial port. The print
request is a maintained action.
