3.8.3 On-load/off-load remote control
The HYDROVANE Pro control system allows the
operator to switch the compressor into on-load or off-
load from a remote point through the connection of two
potential-free contacts. This function is needed when
using an external control for example.
Go to the [OPTIONAL IN-/OUTPUTS] menu where you
must program one input with the ENAB.REM.LOAD
function and another with the REMOTE LOAD function.
The unit can now be switched to on-load or off-load
using these two inputs.
In the circuit diagram (Fig. 5) we have assigned inputs
as follows:
INPUT 1:ENAB.REM.LOAD
INPUT 2:REMOTE LOAD
You can of course program the inputs any way you
choose.
If input 1 is activated, the unit can only be switched into on-
load or off-load by remote control. Both pressure ranges
and time control mode are interrupted (decoupled). If input
2 is now activated, the compressor is in on-load. If input 2
is not activated, the compressor is in off-load.
If the supply pressure exceeds the preset operating
pressure of 0.5 bar (7 psi), the WARNING LINE PRESS
indication appears on the display. Remote control is
deactivated at the same time. The unit now runs again
using one of the preset pressure ranges until the
WARNING LINE PRESS is acknowledged.
