Test run
To check for leaks and function, first run the machine with
water
only. Fill in the
etching chamber either via the inlet ball valve or from above by opening the ex-
haustion hood and remove the cover. Fill the close loop rinse from above. In both
tanks do not exceed the minimum and maximum level, otherwise the heater or
pump may get damaged. The level mark
min - max
is located on the transparent
front side of the machine.
Note: The level and temperature must always be monitored by the operator.
Turn on the main power switch. The white indicator light should light up.
Turn on the transport and adjust the speed.
Check the function of etching and rinsing pump by pressing the green button be-
low
pump
. The spray pressure for etching zone, rinsing zone and freshwater tank
can be set by ball valves.
Turn on the heater.
Warning: The heater may be switched on only with filled tanks.
If no
front panel key is pressed, the display shows the actual value of the thermo-
stats. With increasing heating time, the display must increase.
If you press the SET-button the target value is displayed in the screen. If
you additionally press the "UP" or "DOWN" button, the set point is increased
or decreased. By default, the heater is set to the target value 45 °C.
Drive a test board through the machine and check the function of the prox-
imity switch.
Open the hood - the pump must switch off (safety lid switch).
Empty the machine again via the ball drain valves.
Initial filling
Before initial filling, make sure all ball valves are closed again !! Fill the
etching zone as in the test run, but this time with the desired chemical. If ne-
cessary, use a drum pump or similar. Observe the safety instructions and Material Safety Data Sheet of
the chemical. Set up chemicals outside of the machine!
Operating
Board transport:
If you look at the machine from the front, insert the boards from the right side of the machine.
For this they are placed on the first conveyor roller and advanced to the first pair of rollers.
If there is no outlet table at the rear of the machine, you need to take the boards from the machine
manually, otherwise they will fall to the ground.
Temperature:
The temperature to be set depends on the etchant used. When etching with sodium it should be about
40 °C, with copper chloride or sulfate about 30 °C and with ferric chloride up to 45 °C.
