The status of the input signals can be seen at the top and right hand side of the screen with
deactivated inputs shown as a grey circle and activated inputs shown as a red circle. The
external control system outputs can be activated and the input to the Hydro-Control checked.
To stop the Hydro-Control from responding to the inputs being received (for example, starting
a mix when the Start signal is activated) the Disable Inputs button can be pressed. Whilst the
inputs are disabled, the button is changed to Enable Inputs. Changing from this screen by
pressing the Next or Menu buttons will also re-enable the inputs.
Individual outputs can be activated and deactivated by pressing on the grey circle next to the
text which allows the link to the external control system input to be checked. Activated outputs
display with a red circle (as seen from the 'Alarm' output which is activated).
The Admix Signal is used to control at which point during the mix cycle the Admix output is
set. If the parameter is set to All, then the Admix output is set whilst the Hydro-Control is running
a mix which is the same function as the Busy Mode parameter 'All' on the Hydro-Control V.
Other options are explained in the section on Admix control in Chapter 5.
The Water Tank Full signal is used to indicate that the water weigh scale is full. If configured
the water tank full signal can also be used to initiate a system shut down. This can be used in
conjunction with a UPS. To configure the Shutdown signal select 'Shutdown' from the selection
box (Figure 19).
