The protectors are activated when the temperature becomes too high. When temperature returns to normal, the protector resets automatically. 8 Overcurrent relay for compressor (K4S, K5S) The overcurrent relay protects the compressor motor in case of overload, phase failure or too low voltage.

The pump must run now. 2 Set the desired flow by turning the pressure regulating valve. NOTE ■ The desired flow is depending on the capacity of the chiller and the desired temperature difference between water inlet and outlet (∆t). ■ If manometers are installed, the flow can be deduced from the pressure difference over the pump.

In order to ensure optimal availability of the unit, a number of checks and inspections on the unit and the field wiring have to be carried out at regular intervals. If the unit is used for air conditioning application, the described checks must be executed at least once a year. In case the unit is used for other applications, the checks must be executed every 4 months.
