startup unit

[QQQ]

Hello all!
The rules of start up the equipment (chillers) strictly order
the certain set of actions.
I wonder,
How it can be made by the BEST way? It's obviously,
that for SUCH checks there is a necessity to create the certain conditions SPECIALLY.
a)Low oil level cutout
b)High motor temperature cutout
c)High oil temperature cutout
d)Circuit breaker cutout
e)Freeze setpoint cutout
Any ideas and advice are approved.

Condensor fan circuit breaker,
Phase order control.

Don't forget the water flow switch - without this you will soon have a block of ice on the evaporator!

Check to solenoid valve to make sure that it opens on compressor run signal and closes when the compressor stops - without this you will get liquid migration to the evaporator.
