Inputs Configuration Rules.
It is necessary to have into consideration the following rules for a correct digital input configuration
when the Pump Program is active:
Mutual Exclusion Rule:
o
If the pump program is deactivated, the user can only set options from 0 to 23 for the
digital inputs, which are options for functionalities related to the standard program.
o
If the pump program is active, the user can only set options from 50 to 69 for the digital
inputs, which are options for functionalities related to the pump program.
System Start Terminal Rule (Automatic):
To ensure the start and the stop of the system, the user must first of all configure one of the
digital inputs as option ‘50 PMP START/STP’. On the contrary, the drive does not allow
configuring any other option. Once this is done, it is possible to configure the resting inputs
as necessary (respecting always the configuration rules).
Rule for Multiple References Selection:
With the pump program is possible to operate using up to 8 different regulation setpoints in
PID mode (settable in G25.1.5 to G25.1.12). To active each different setpoint 3 digital inputs
configured as options 63, 64 and 65 can be used. It is necessary to take into consideration
the following items:
o
No Digital Input could be configured as ’64 SETPONT PIN2’ unless previously other
different input has been configured as ’63 SETPONT PIN1’.
o
No Digital Input could be configured as ‘65 SETPONT PIN3’ unless previously two
different inputs have been configured as options ‘63 SETPONT PIN1’ and ‘64 SETPONT
PIN2’.
Rule for Selection / De-selection of Auxiliary Pumps:
For selecting one auxiliary pump it is necessary to act in the following way:
o
Set any digital input to options ‘52 FIX PUMP1 FLT’, ‘53 FIX PUMP2 FLT’, ‘54 FIX
PUMP3 FLT’, ‘55 FIX PUMP4 FLT’ or ‘56 FIX PUMP5 FLT’.
o
To enable the control of the pump in the corresponding parameter G25.9.1, G25.9.2,
G25.9.3, G25.9.4 and G25.9.5 respectively.
To remove this fixed pump configuration and release the relay for another different use, it is
necessary to:
o
To disable the control of the pump in the corresponding parameter G25.9.1, G25.9.2,
G25.9.3, G25.9.4 and G25.9.5 respectively.
10.20.6.
Outputs Configuration.
Regarding to the outputs, it is useful to take into account some considerations which will help you
for the correct configuration of the system.
Digital outputs.
There are some configuration options for the outputs that are only available if the pump
program is operative, but they cannot be used in the standard program: ’28 PUMP CNTRL’,
’29 JOCKEY PUMP’ and ’30 PRIMING PUMP’. The needed information has been detailed in
the corresponding group G8.1 Digital Outputs.
