Using the power supply

Analogue in./out. selects the voltage range for the analogue
set values inputs and actual value outputs:

Analogue voltage Default: 0...10V
= 0...10V Selects 0...10V for 0...100% set/actual values.
= 0...5V Selects 0...5V for 0...100% set/actual values.
The reference voltage at pin VREF is automatically adjusted to
the above selection and will be either 5V or 10V.

Digital inputs defines if the digital control inputs will act at
LOW or HIGH level.

REMOTE /5
Default: LOW
= LOW Unit switches to analogue remote control, if
the pin is tied to LOW (ground).
= HIGH Unit switches to analogue remote control, if
the pin is tied to HIGH.
Caution! This pin is tied to HIGH level by default. It means,
that if setting HIGH is chosen and the pin is left open, the
device will permanently stay in analogue remote control!
