If you want to change the time, then press the arrow key. The dis-
play shows Time: 00:00 arrow up/down ok. The cursor jumps to the
first 00:00. Now use the arrow keys to adjust the desired value.
Pressing the Enter key you confirm the value and the cursor
moves to the next digit (10:00). Now enter the remaining digits in
the same way. Pressing "enter" you confirm the setting and you
jump back to the main menu.
If you press Enter in the main menu, the timer starts and the pump
switches on. On the LCD the remaining time, the current temperat-
ure and the activity of the heating (H) are shown.
If you open the lid, the timer and the pump stop. The display shows
„stop → cap open.
If you close the lid again, the job continuous.
When the job is finished, you will hear a beep and on the LCD ap-
pears "done → ok". Pressing the Enter key, you return to the main
menu.
When the temperature of the etchant reaches 55°C (eg by exo-
thermic reaction), an audible alarm sounds and the display shows the
message "Attention temperature too high".
If the temperature is getting too high during the etching process, the
pump will continue to support the cooling.
Now, the operator must take measures to lower the temperature.
As long as the temperature is > 55°C, the alarm remains, and only by
turning off mains the machine can be stopped.
If the temperature falls below the threshold temperature, the alarm
can be cancelled by pressing the Enter key. In stand-by mode (ma-
chine is turned on, but no etching process is taking place) the temperature is still monitored and an aud-
ible and visual alarm is displayed when reaching the threshold temperature of 55°C. The pump will start if
lid is closed and will stop when lid is opened. If the temperature falls below the threshold temperature
and the alarm is cancelled the pump turns off again.
Setting the target temperature:
To set the target temperature,
press both arrow keys, during the welcome screen, until the tem-
perature menu appears. Then set the desired temperature with the
arrow keys and press Enter.
