Control of the FP89 cooling machine:
The mains switch is turned on. After pressing the start/stop button, the
cooling machine is automatically switched on or off by the circulator. In
the start mode of the circulator, the cooling machine runs continuously.
Immediately after starting the cooling machine, the output of the system
is reduced to a minimum value for a defined period in order to equilibrate
the cooling system. Afterwards the output of the cooling machine is
ramped up to the capacity required by the circulator.
A control of the capacity limitation subject to the temperature of the bath
is stored in the circulator. This is used to increase the operational
reliability and does not affect the maximum capacity of the cooling
machine.
