When the safety device has turned off the unit, identifiable by the red alarm lamp (2a) lighting up, proceed
as follows:
•
Disconnect the unit from the power supply.
•
Have the cause of the fault examined and rectified by a technician.
•
Release safety thermostat class 2 by pressing reset button (2b).
•
Restart the unit as described in chap. 5.
Setting:
The diagram given in chap. 2.3 indicates the drying temperature to be set on the controller in relation to
the quantity of the introduced solvents. This must not be exceeded. For this reason, adjust the tempera-
ture safety device according to the selected set-point.
DANGER
Excessive drying temperature.
Danger of explosion.
Danger of death.
∅
Do NOT exceed the maximum drying temperature for the solvent quantity.
To check at which temperature the safety device activates, turn on the oven and set the required nominal
value on the temperature controller.
The scale division from 1 to 10 corresponds to the temperature range from 30 °C / 86°F up to 320 °C /
608°F and serves as a setting aid.
•
Detach the plastic cover over the temperature safety device class
2 (2) with a suitable Phillips screwdriver.
•
Turn the control knob (2) of the safety device using a coin to its
end-stop (position 10) (unit protection).
•
When the set point is reached, turn back the control knob (2) until
its trip point (turn it counter-clockwise) is reached.
•
The red alarm lamp (2a) lighting up identifies the trip point; and the
reset button (2b) pops out.
•
The optimum setting of the safety device is obtained by turning the
knob clockwise by approx. one graduation mark on the scale.
•
Push the reset button (2b) in again.
•
Restore the plastic cover to prevent misadjusting
Figure 10: Setting the safety
device class 2
The unit is only active when the reset button (2b) is pushed in.
When the safety thermostat class 2 responds, the red alarm lamp (2a) illuminates, the reset button (2b)
pops out and the unit turns off permanently at all poles. Only the fan keeps turning for safety reasons.
Check the safety thermostat regularly and adjust it following changes of the set-point.
Fixed value operation:
Adapt the temperature safety device every time the set-point for
temperature is changed. Set the set-point of temperature safety device by about 5 °C to 10
°C above the controller temperature set-point.
Program operation:
Adapt the temperature safety device to the highest temperature set-
point value of the program actually used.
Functional check:
Test the functional capability of the safety thermostat at appropriate intervals. It is recommended having
this check performed by the authorized service personnel, e.g. before the beginning of a long working
process.
