Energise (open) when the compressor starts,
de-energise (close) when the compressor stops.
If the system is designed to pump-down on stopping, the
liquid line solenoid valve de-energises (closes) when the
pump-down sequence begins.

Normally energise (close) when the compressor starts,
de-energise (open) when the compressor stops.
Under low pressure difference conditions, de-energise
(open) while the compressor is running in order to lower
the evaporator gauge pressure.
