Operating Instructions DIGITAL II Version 2.0
Control functions
1. Heat protection / level regulator
If the level is too low in a heated bath the heater is switched off by the thermo couple. The display
shows a warning signal over the full area. The si
gnal can be confirmed with “ok” but the heater
remains off. An overheating of heater or tank is avoided. When the bath is refilled the heater will be
automatically turned on.
2. Total charge
For each basin a total charge can be set. So a metal content is determined, which can be deposited.
When this value is exceeded a warning appears and the bath should be regenerated. To set the total
charge press button “Basin” for 3 sec and enter the desired value and (important!) basin. After this
the display shows the signal
If the total charge is matched with a desired program (by setting the number of the basin in that
program) the control is done for this process. Do as following:
1. Press button “basin” 3 seconds
2. Enter the desired value and basin
3. Pres
s “save”
4. Leave with “OK”
5. Press button “progr” and choose the desired one
6. Set the same basin as in point 2
7. Leave with “OK”
8. Press “progr” for 3 seconds and save the process
9. Leave with “OK”
If basin number 0 is selected you can work manually (without control).
Example total charge Rhodiumbath
The deposition rate of the bath is 6 mg / Amin (see data sheet of the chemical supplier). For this the
total charge of 200 Amin can be set. That means that after receiving this value 1200 mg of rhodium
are deposited (6 mg/Amin x 200 Amin = 1200 mg Rh) and the bath can be regenerated accordingly. A
consisted quality is ensured. Rinsing losses are not taken into account!
Heaters
Up to max. two heaters can be connected with the corresponding sensors on the unit. These can be
used in any tank. The tanks where heater and sensor hang will be heated. The heaters can be turned
on at the control panel. The display shows a signal as soon as a heater is active.
Attention: Heaters only for intended use.
