Automatic operation
Extremely hot / cold surfaces, connections and thermal fluids
BURNS/FREEZING OF LIMBS
Surfaces, connections and tempered thermal fluids can be extremely hot or cold depending on
the operating mode.
Avoid direct contact with surfaces, connections and thermal fluids!
Wear your personnel protective equipment (e.g. temperature-resistant safety gloves, safety
goggles).
During an active circulation, the thermal fluid circuit is shut off by shut-off valves
MATERIAL DAMAGE TO THE CIRCULATING PUMPS INSTALLED IN THE TEMPERATURE CONTROL UNIT
Do not close the thermal fluid circuit during an active circulation by means of shut-off valves.
Warm the thermal fluid to room temperature before stopping the circulation.
The pump flow can be closed by using
>Circulation flow<
[1] and
>Circulation return<
[2]
but do
not do so
while the temperature control unit is in operation. The pump may be switched off due to
overheating or high power consumption if the temperature control unit is operated with a shut
pump flow.
5.1.1
Temperature control
5.1.1.1
Starting the temperature control process
The temperature control process can be started after filling and complete venting.
PROCEDURE
Go to the “Home” screen.
Tap on the “Start” touchbutton.
Confirm the start of temperature control by tapping on “OK”.
The correct selection will be displayed graphically and temperature control will start immediate-
ly. If tapping on “OK” is not correct, this is displayed graphically for 2 seconds. After this, the dis-
play will return to the “Home” screen again. Try to start the temperature control unit again.
5.1.1.2
Ending the temperature control process
When the temperature control unit is switched off, the thermal fluid temperature is high-
er/lower than room temperature
DAMAGE TO THE TEMPERATURE CONTROL UNIT AND THE GLASS APPARATUS/APPLICATION
Bring the thermal fluid up to room temperature using the temperature control unit.
Do not close the shut-off valves in the thermal fluid circuit.
The temperature control can be ended at any time, the pump continues to run for approx. 30 sec-
onds. The compressor is switched off after the stepper motor valve has reached a defined position
to control the cold output.
PROCEDURE
Go to the “Home” screen.
Tap on the “Stop” touchbutton.
Confirm the stop of temperature control by tapping on “OK”.
The correct selection will be displayed graphically and temperature control will stop immediately
and the pump with overrun for about 30 seconds. Wait until the pump stops. If tapping on “OK”
is not correct, this is displayed graphically for 2 seconds. After this, the display will return to the
“Home” screen again. Try to stop the temperature control unit again.
