PROGRAM USER MODULE
There are six User Input; four external User
Inputs, and two front panel Function keys, which
have various programmable capabilities. An
external User Input is active when tied to common.
A front panel function key is active when pressed.
The options for each User Input are the same,
except as noted below:
1. The two Function keys (F1 & F2/RST) DO NOT
have the Program Disable (PGM.DIS.) option.
2. Only User Input 4 has the Inhibit Function.
The operator can select only one option for each User
Input. The operator may have to enter a second sub-menu
for some options before entering the edit menu. The
following flowchart shows only the user portion:
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.
