• Offset (X1, Y1)
• Offset (X2, Y2)
For an example of the offset function and more information, see Example: P900
SUBMENU OFFSET (page 105).

Selects the offset input. Possible setting are:
Setting Offset calculation
Off Disabled
An. U1 0-10V Calculated from the voltage signal (0 - 10 V) connected to
the terminals X3/7-8-9 (Required Value 1)
An. U2 0-10V Calculated from the voltage signal (0 - 10 V) connected to
the terminals X3/10-11-12 (Required Value 2)
An. I1 0-20mA Calculated from the current signal (0 - 20 mA) connected
to the terminals X3/7-8 (Required Value 1)
An. I1 4-20mA Calculated from the current signal (4 - 20 mA) connected
to the terminals X3/7-8 (Required Value 1)
An. I2 0-20mA Calculated from the current signal (0 - 20 mA) connected
to the terminals X3/10-11 (Required Value 2)
An. I2 4-20mA Calculated from the current signal (4 - 20 mA) connected
to the terminals X3/10-11 (Required Value 2)
If the incoming current signal drops to below 4 mA, a warning message is shown on the
display; however, HYDROVAR continues to operate without the offset function.

Set the representation of the sensor range: the value depends on the maximum range of
the connected offset sensor. A higher offset range gives a higher signal input resolution.
