Figure 3-5 SR469 KEYPAD
The SR469 messages are organized into pages under the main
headings, Setpoints and Actual Values. The [SETPOINT] key is
used to navigate through the headers of pages of programmable
parameters. The [ACTUAL] key is used to navigate through the
headers of pages of measured parameters.
Each page is broken down further into logical subgroups of
messages. The [MESSAGE] up and down keys may be used to
navigate through the subgroups.
The [ENTER] key is dual purpose. It is used to enter the
subgroups or store altered setpoint values.
The [ESCAPE] key is also dual purpose. It may be used to exit
the subgroups or to return an altered setpoint to its original value
before it has been stored.
The [VALUE] up and down key is used to scroll through variables in the setpoint programming mode. It will increment and decrement
numerical setpoint values. Alternatively, these values may be entered with the numeric keypad.
The [HELP] key may be pressed at any time for context sensitive help messages.
3.1.6 ENTERING ALPHANUMERIC TEXT
In order to allow the SR469 to be customized for specific applications, there are several places where text messages may be
programmed. One example is the MESSAGE SCRATCHPAD. To enter alphanumeric text messages, the following procedure should be
followed:
Example: to enter the text, "Check Fluid Levels"
•
press [.] to enter text edit mode,
•
press the [VALUEs] or [VALUEt] key until 'C' appears, press [.] to advance the cursor to the next position,
•
repeat step 2 for the remaining characters: h,e,c,k, ,F,l,u,i,d, ,L,e,v,e,l,s
•
press [ENTER] to store
3.1.7 EN/- SIGNS
The SR469 does not have a ‘+’ or ‘-’ key. Negative numbers may be entered in one of two manners. First, immediately pressing the
[VALUE UP] or [VALUE DOWN] key will cause the setpoint to scroll through its range including any negative numbers. Alternately, once
a setpoint message is entered, after pressing at least one numeric key, pressing the [VALUE UP] or [VALUE DOWN] key will cause the
sign to change if applicable.
