Note
: If the Pump Control program is selected and then de-selected, all of the Digital Inputs will
be reset to mode ‘00’ (i.e. unused). It will be necessary to individually configure Digital Input
functionality to suit the application should this occur. This guarantees safe installation and
operation in order to prevent any external hardware causing damage to the equipment.
Note:
Digital outputs will be affected by pump control activation.
To select an auxiliary pump you must proceed like this:
o
Set any free digital input to the options ‘52 FIX PUMP1 FLT’, ‘53 FIX PUMP2 FLT’ or ‘54
FIX PUMP3 FLT’.
o
Enable the pump control in the corresponding parameter G25.9.1, G25.9.2 and G25.9.3
respectively.
To remove the configuration of that fixed pump and release the relay for other use you must:
Disable the pump control in the corresponding parameter G25.9.1, G25.9.2 and G25.9.3
respectively.
