7.1 Displays in the event of faults
An alarm signal (xx Hz) is sounded in the event of a fault and the temperature control unit displays
an alarm or warning message on the OLED display.
Code Cause Effect, measure
001 Overtemperature alarm
The internal temperature is above the set
value of the overtemperature protection.
The overtemperature protection was
triggered.
The internal temperature of the thermal fluid is in the
upper allowable extreme range. The temperature control
unit can be turned on again only when the temperature of
the thermal fluid has returned to normal parameters.
Check whether the thermal fluid used matches your
required parameters if overtemperatures repeatedly shut
down the unit.
002 Tmax exceeded
The internal temperature is above the set
setpoint limit.
The internal temperature of the thermal fluid is above the
setpoint limit set in the controller. Control continues.
003 Tmin undercut
The internal temperature is below the set
setpoint limit.
The internal temperature of the thermal fluid is below the
setpoint limit set in the controller. Control continues.
004 Error float test Check the thermal fluid level.
KISS: Is the float blocked or sticky?
Please contact Customer Support if the thermal fluid level
is sufficient and the float of the KISS controller moves
freely.
005 Low-level alarm
No enable signal, level alarm
Control is inactive. (Pump off, compressor off, heating off)
Check the fill level of the thermal fluid.
Restart impossible until the thermal fluid level is OK.
006
Overpressure cutout triggered
The pressure in the condenser is too high.
The overpressure cutout (pressure
switch) has triggered.
Temperature and pressure increase in the condenser. An
overpressure cutout (pressure switch) is installed to
protect the temperature control unit against excessive
pressure.
Water cooling:
a.) Is the cooling water supply correctly connected?
b.) Is the suction strainer (dirt trap) clogged?
c.) What is the cooling water temperature, the cooling
water flow rate and the cooling water pressure?
Air cooling:
a.) Is the heat exchanger or the grille dirty?
b.) Does the fan turn if the cooling machine is switched
on? If the fan does not turn: Contact Customer Support.
009
011
Sensor F1 short
Sensor F2 short
Short-circuit at the internal temperature
sensor F1 or at the external temperature
sensor F2.
Control is inactive. (Pump off, compressor off, heating off)
Check the sensor.
010
012
Sensor F1 open
Sensor F2 open
The internal temperature sensor F1 or the
external temperature sensor F2 is open.
Control is inactive. (Pump off, compressor off, heating off)
Check the sensor.
