71 / 77 83000102.Kf
Outlet temp. Max STOP
Maximum outlet temperature
has been reached, the unit
switches off! Thermal
overload!
Reduce the thermal load on the cold
water side!
Outlet temp. Min STOP
Minimum outlet temperature
has been reached, the unit
switches off! Risk of frost!
The machine's ambient temperature
may have to be increased. Cold water
temperature may have to be
increased.
Tank min level warning
Level in the tank is no longer
optimal - unit continues
functioning
Top up tank with fresh water as
described in the specification
Tank min level STOP
Level in the tank is no longer
sufficient - unit stops
functioning
Top up tank with fresh water as
described in the specification
Water inlet pressure
warning
Excessive pressure at unit
inlet!
Reduce pressure!
Water inlet pressure STOP
Pressure at the unit inlet is
too high!
Reduce pressure!
Pump pressure 1 min
warning
Pressure at the pump outlet
1 is low!
Increase pressure loss downstream of
pump 1!
Pump pressure 1 min
STOP
Pressure at the pump outlet
1 is too low!
Pump runs out of the characteristic
curve, increase pressure loss
downstream of pump 1!
Pump pressure 1 max
STOP
Pressure at the pump outlet
1 is too high!
Reduce pressure loss downstream of
pump 1! Gate valves in the external
piping may need opening or filters
must be cleaned.
Pump pressure 2 min
warning
Pressure at the pump outlet
2 is low!
Increase pressure loss downstream of
pump 2!
Pump pressure 2 min
STOP
Pressure at the pump outlet
2 is too low!
Pump
runs out of the characteristic
curve, increase pressure loss
downstream of pump 2!
Pump pressure 2 max
STOP
Pressure at the pump outlet
2 is too high!
Reduce pressure loss downstream of
pump 2! Gate valves in the external
piping may need opening or filters
must be cleaned.
Overheating
Overheating cannot be
permanently adjusted to the
defined value. There is a
problem in the refrigeration
circuit.
Contact the KKT chillers Service.
Low pressure warning
The low
-
pressure of the
refrigeration circuit is
approaching the critical
range for the system
configuration. Evaporator
may be contaiminated
Check the flow through the evaporator.
Low pressure STOP
The low
-
pressure of the
refrigeration circuit is within
the critical range for the
system configuration. The
evaporator may be
contaminated
Check the flow through the evaporator.
