5.1.3.10 P1: Setting the set-point P1 function of input 2
When the parameter i2 is set at a value other than zero, input 2 is used to select one of the two settable set
points. The first is SP (see 5.1.1.1) and the second is P1.
5.1.3.11 O1: Setting output 1 function: alarm active

5.2 Display-only
parameters
From normal operation status the following quantities can be displayed by pressing the MODE key:
5.2.1
User’s parameters (accessed by the MODE key)
From normal operation status (Sb or Go on the display) after pressing the MODE key once, “Fr” appears on
the display.
All the following quantities can be displayed at further MODE key pressures.
5.2.1.1
Fr: Display of the current rotation frequency (in Hz)
5.2.1.2
UP: Display of pressure (measured in bar)
If pressure exceeds 15 bar, the display keeps showing “15”.
5.2.1.3
C1: Display of the electro pump’s phase current (in A)
5.2.1.4
AS: Display of the configuration with “Da Vinci”
This parameter appears on MODE menu when communication between “Da Vinci” controller board and
PWM and shows how the former configured the latter. The possible cases are:
rd
(“ready”) the PWM is regulating according to the set points decided by the controller board
rS
the PWM is configured as spare device and is activated in case of block of other devices
dS
(“disable”) the PWM is disabled and it is never activated.
5.2.1.5
UE: Display of the version of the software with which the appliance is equipped
