4.3.Front Panel Screens
Here follows a complete breakdown of all
a)Main Screen (not changing setpoint)
The main screen comes in two forms. The first shows the main channel input data (with range, fullscale and calibration applied) and the associated units string. If an input is over range (more than 15% above full scale voltage) then the data value is replaced with the over range error – “RANGE!”. This screen also shows the current mode of the setpoint, if not in AUTO (i.e. OPEN or CLOSE). If either of the relays have been tripped then they are also indicated as such on the far right of the screen.
Switch Functions: |
|
Func | No function * |
◄ | Go to Main Menu screen |
► | Enable setpoint mode override, active for 2 seconds |
► (override mode) | Change setpoint mode to AUTO |
▲ | Change setpoint value (main screen changes as below) |
▲ (override mode) | Change setpoint mode to OPEN |
▼ | Change setpoint value (main screen changes as below) |
▼ (override mode) | Change setpoint mode to CLOSE |
Zero | Perform input rezero (if held for 3 seconds) |
*By default, the Func switch does nothing while this screen is displayed.
b)Main Screen (changing setpoint)
The other form of main screen is shown when changing the live setpoint (via an initial press of the ‘▲’ or ‘▼’ switches). All the information shown on the first main screen is shown here (albeit some items are resized or repositioned) but in addition the current setpoint value is also shown. Note that this screen is not permanent – if the ‘▲’ or ‘▼’ switches are not pressed at all for 5 seconds, then the main screen reverts to the first variety shown previously.
Switch Functions:
Func | No function*(See (a) above) |
◄ | Go to Main Menu screen |
► | Enable setpoint mode override, active for 2 seconds |
► (override mode) | Change setpoint mode to AUTO |
▲ | Change setpoint value (hold for continuous change) |
▲ (override mode) | Change setpoint mode to OPEN |
▼ | Change setpoint value (hold for continuous change |
▼ (override mode) | Change setpoint mode to CLOSE |
Zero | Perform input rezero (if held for 3 seconds) |
