Manual operating
The EWIO2 has manual operation of the I/O outputs.
This is done by the keys T1 to T8, which can be configured for various functions, and the keys
AO1 to AO3 for manual operation of the analog outputs. These are not configurable.
When delivered (factory settings), the push-buttons are assigned to the relay and TRIAC
outputs in the Web I/O variants. T1 to T3 are assigned to relays 1 to 3, T4 and T5 to TRIAC 1
and 2, and T6 to T8 to relays 4 to 6. In the data logger versions, the buttons T1 to T4 are
assigned to relays 1 to 4 and the buttons T5 to T8 are assigned to digital outputs D1 to D4.
Long keystroke, greater than 1 second, switches between manual and automatic operation of
the corresponding output. Manual operation is indicated by a green LED.
A short keystroke, less than 1 second, changes the state of the binary outputs.
Thereby, the analog output to be changed is selected with the keys AO1 to AO3. This is
indicated by flashing of the corresponding green LED.
The keys

then change the output voltages. The longer the button is pressed here, the
faster the voltages change. The blinking frequency of the green LED also changes.
