Red Lion LEGEND - Manual (Page 24)

PROGRAM USER MODULE (Cont’d)
BINARY MESSAGE REQUEST (BIN MSG REQ)
Two, three, or all four of the external User Inputs can be configured as
binary message request inputs. When configured as binary message request
inputs, the individual user input options are not displayed or available. The
inputs are active when pulled low (to common). In order for a message to be
requested, the inputs must remain stable for 100 msec minimum. The number
of messages that can be requested varies with the mode (# of bits) selected; for
2bit - 3 messages, 3bit - 7 messages, 4bit - 9 messages. Message #0 cannot be
requested, since binary state 0 is used to indicate no request.
Example: If the Legend Plus is set up for 2 bit Binary Requests, User Inputs 1
and 2 do not appear in the Program User loop for programming. Activating
User Input 1 displays Message 1, and activating User Input 2 displays
Message 2. Activating both together displays Message 3.
Changing the individual binary message request inputs slowly may cause
unwanted message requests, if several bits need to be changed.

NO MODE
If a User Input terminal or a Function key is activated, it is ignored.
MAINTAINED RESET (MNT RST)
Maintained reset has four selectable options. 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 Count
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 is the last
reading obtained before the reset. The next reading occurs after the
release of the reset and the expiration of the measurement period.
The Rate display does 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 according to the programmed reset
action.
With Maintained reset, the value continuously resets as long as the User
Input or Function Key is active. 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 starts updating (counting), 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 any or all of the Outputs, 1 through 6, reset.
If the output is active, it resets 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 the Phase
programmed in the Program Outputs Module.
SET OUTPUT (SET OUT)
The operator can select to have any or all of the Outputs, 1 through 6, set. If
the output is inactive, it goes (sets) to its active state when the User Input or
Function Key is activated. If an output is programmed for a time delay, the
output does NOT latch, but times 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 the Phase
programmed in the Program Outputs Module.
