Setting:
To check the response temperature of the safety device class 3.1, turn on the chamber and set the de-
sired set point at the temperature controller.
The sections of the scale from 1 to 10 correspond to the temperature range from 0 °C /
32 °F
to 120 °C /
248 °F
and serve as a setting aid.
•
Turn the control knob (14) of the safety device using a coin to its end-stop (po-
sition 10) (unit protection).
•
When the set point is reached, turn back the control knob (14) until its trip point
(turn it counter-clockwise).
•
The trip point is identifiable by the red alarm lamp (14a), the message “TEMP
ALARM” on the controller display and the buzzer sounds. Reset the buzzer with
the “RESET” key on the controller.
•
The optimum setting for the safety device is obtained by turning the control
knob clockwise by approximately two scale divisions, which shuts off the red
alarm lamp (14a).

safety device class
3.1
Check the setting regularly and adjust it following changes of the set-point or charge.
10.3.2 Temperature safety device class 3.2
The safety device class 3.2 is equivalently set to a minimum temperature the
unit will not fall below. This protection against prohibited low temperatures
can, for example, serve to protect sensitive cultures from cooling down too
much.
If the control knob (15) is turned to its minimum (position 1), the safety de-
vice class 3.2 has no effect. If it is set to a temperature somewhat lower than
that selected by means of the controller, it functions as a protective device
for the material under treatment.
If the temperature safety device class 3.2 has assumed regulation, identifiable by the red alarm lamp
(15a) lighting up, the message “TEMP ALARM” on the controller display and the buzzer sounds, please
proceed as follows:
•
Reset the buzzer with the “RESET” key on the controller.
•
Disconnect the unit from the power supply.
•
Have an expert examine and rectify the cause of the fault.
•
Start up the unit again as described in chap. 5.
Setting:
To check the response temperature of the safety device class 3.2, put the unit into operation and set the
desired set point at the temperature controller.
The sections of the scale from 1 to 10 correspond to the temperature range from -40 °C /
-40 °F
to +160
°C /
320 °F
and serves as a setting aid.
•
Turn the control knob (15) of the safety device by means of a coin to position
1 (thermostat without effect).
•
When the set point is reached, reset the safety device to its trip point (turn it
clockwise).
•
The trip point is identifiable by the red alarm lamp (15a), the message “TEMP
ALARM” on the controller display and the buzzer sounds. Reset the buzzer
with the “RESET” key on the controller.
•
The optimum setting for the safety device is obtained by turning the control
knob counter-clockwise by approximately two scale divisions, which shuts off
the red alarm lamp (15a).
