Hint:
When working with the 230V loads, switch off the DPK and disconnect it from the power
source!
Opposite of other regulating units for 230V, the DPK checks the loads at the power up precedure by
using a current measurement. So a clear statement about a load disconnection could be given.
For all channels the set value in ampere can be displayed.
To check the heater current a clamp-ampmeter with true RMS measurement should be used. For
low voltage nozzles a range of 0-150A is required. High voltage nozzles requires a range of 0-10A.
If there are problems with the installation of the DPK, please contact our service department for
help. Please use the service form in appendix E and send it to the next service department.
6.3 Installing new EPROM updates
Hint:
Attention: Disconnect the mains voltage and take care that there is no voltage at the DPK
before opening the device!
Please follow the safety instructions!
To install a software update disconnect the power and thermocouple connections from the DPK.
Disconnect also the serial interface to a molding machine.
Now remove the top cover of the DPK and get the EPROM out of the module LR28. When
installing the new EPROM take care of the right direction and fit in socket of the circuit.
After that get the EPROM out of the module LR27. When installing the new EPROM take also care
of the right direction and fit in socket of the circuit.
Following this step close the cover of the DPK.
Attention!
Do never exchage the EPROMs!
After turning on the DPK again, the DPK performs an update and an adjustment.
Now the DPK should work normally.
The actual software version is displayed in the right lower edge of the display, when the DPK is
turned on.
