6-14 ST3000 Smart Transmitter Series 900 Electronic Differential Pressure/Pressure Transmitter
6-3-4 :Rules of key operations and interaction with screens
6-3-4-1 General rules for key operations
The following points should be noted when operating the SFC keyboard.
- Press keys firmly and slowly. If the screen does not respond, this means the key input
has not been accepted. Press the key slowly once again.
- There are active keys and inactive keys depending on the screen in the display win-
dow. When an inactive key is pressed, pressing the [CLR] key will restore to a state in
which key input can be accepted. After this, press an active key.
6-3-4-2 Interaction rules
The SFC can be operated on an interactive basis. Interact with the SFC according to
the following rules:
- To answer “Yes” to a question on the screen, press the [ENTER] key. Answering
“Yes” to a question on the screen of the CONFIG functions normally moves to a hier-
archy one level lower. However, answering “Yes” to the prompt of “EXIT...” exits the
function and returns to a hierarchy one level higher.
- To answer “No” to a question on the screen, press the [CLR] key. Answering “No” to
a question on the screen of the CONFIG functions normally moves to a hierarchy one
level higher. However, answering “No” to the prompt of “EXIT...”returns to the start
screen of the function.
- To select a different function in the same hierarchy, press [NEXT]/[PREV] keys.
- To scroll the screen in order to select a different item in the same hierarchy and with
the same function, press the [MENU ITEM] key. While the CONFIG function is
active, pressing the [SET] + [CLR] keys at any hierarchy will show a screen “EXIT
CONFIG?”. Pressing the [ENTER] key here makes it possible to exit the CONFIG
function at a stroke.
6-3-4-3 Display of # mark
While the SFC is communicating with the transmitter, a # mark may appear in the last
column at the bottom of the screen. The # mark is an alarm which appears under the
following circumstances.
- A minor fault has occurred.
- The transmitter is operating in constant current generation mode or special mode.
When the # mark appears, check the status of the transmitter with the [STAT] key and
take appropriate action with reference to “Error Messages and Action” on page 2-45.
