Common terminal wiring configurations
Relay wiring
Each controller has two programmable form C relay outputs. The relay terminals are
located in various locations on the controller depending on the frame size.

Environment according to EN 60664–1 overvoltage category III/pollution degree 2
Factory default setup
This configuration utilizes the controller factory default settings for I/O. The factory default
settings are configured for Set-up 3, sensorless pressure control with no external
transducer installed. There are no parameters that need to be adjusted to use this
configuration. Set-up 4, sensorless flow control, also uses these default settings for I/O.
Set-ups are changed by adjusting parameter 0-10 Active Set-up. Refer to the
Commissioning section in this manual for details on changing set-ups.
NOTICE:
The factory default settings are configured to require a start signal wired to DI18 as shown
below.
