HMI breakdown
Here follows a complete breakdown of all CCD100 screens:
(a)
Main Screen (not changing Setpoint)
The main screen shows the main channel input data (with range, full-scale 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, but special builds of the CCD100 may include functionality for this
switch. In such cases an addendum to this manual will indicate the function.
(b)
Main Screen (changing Setpoint)
When performing a live setpoint change, the main screen is as previously, but with
the addition of the current setpoint value (initiated via an initial press of the ‘
▲
’ or
‘
▼
’ switches). Note that the setpoint value is not permanent – if the ‘
▲
’ or ‘
▼
’
switches are not pressed at all for 3 seconds, then the setpoint value disappears.
