INFODOSING
The operational function DOSING describes thepreparation for dosing and the DOSING processes of
the ProDos® DPC in connection with the DCM.
PREPARATIONS
Prior to the commencement of the dosing operation,the following settings must be completed at the
ProDos® DPC:
• Entry of DOSING VOLUME (in kg and according to thecast incl. sprue) - see chapter 02.01.2 for additionalparameters:
• with / without dosing volume INCREASE
• with / without dosing volume REDUCTION
• Transfer of % value of FURNACE CHAMBERCORRECTION - adjustment is required, if thedosing volume is continuously increased or reduced when the furnace is gradually emptied.
• Transfer of sec value of t5 LAG TIME -adjustment is required if the inclination or lengthof the channel has been altered.
• Selection of OPERATING MODES - see chapter 02.05:
• Operating mode with / without TOP-STOP
• Operating mode with / without LEVEL-SCANNING
• Operating mode with / withoutSYNCHRONIZATION
• Standard - with SYNCHRONIZATION untilDIE CLOSED
• Exceptions (e.g. three-plate die) - withSYNCHRONIZATION until DIE READY FORINJECTION.
• Selection of OPERATING OPTIONS, selectable insetup mode LOG K02 - see chapter 07.02:
• Operation with ELECTRODE:
• This option is independent of the switchingmode (AUTO / MANUAL)
• Dosing contact (DC) with the melt in thedosing pipe by means of an electrodeattached to the dosing pipe
• During the metal feed process, this electrodeis retracted from the melt area.

• Operation with PneuCo:
• This option is independent of the switchingmode (AUTO / MANUAL)
• Dosing contact (DC) with the melt in thedosing pipe by means of the automaticclosing of the PneuCo nozzle (pneumaticcontact) in the dosing pipe.
• During the metal feed process, the PneuCopressure prevents the melt from penetratinginto this nozzle
ATTENTION
The availability of these options depends on theequipment of the WESTOMAT®.
In addition to the selection of the options in the log,the hardware switch in the switch cabinet must beset to the appropriate position.
• Activation of SWITCHING MODES by means of selecting switch position at DCM:
• Switching mode MANUAL - if I-18 = 0, DCMcontrol not set to AUTO (or semi-AUTO) - seechapter 04.01
• Switching mode AUTO - if I-18 = 1, DCM controlset to AUTO (or semi-AUTO) - see chapter 04.02
• Dosing process (in AUTO-ASYNCHRON)activated
• At open DCM die, the plunger is once fullymoved forward and back into end position.

INTERFACE: WESTOMAT - DCM 02.02
The controls of the die-casting machine (DCM) and theWESTOMAT with the ProDos DPC are connectedvia an interface. This interface is designed accordingto the highest safety standards of the die-castingindustry and coordinates all processes.
The signal interface processes the following signals:
• From DCM to WESTOMAT = input signals to the
ProDos DPC:
• auto-fill test (optional) ............................. I-17
• auto-operation ON .................................. I-18
• die closes .............................................. I-19

• release for injection 1 ............................ O-11• Release for injection 2 (optional) ............ O-12
• disturbance metal supply ............... ........ O-13
• ready for dosing ON ............................. O-14
In addition to the above signals, the controls are alsointerconnected as regards the mandatoryEMERGENCY-STOP. The power supply part of the
WESTOMAT HEATING control is not connected tothe EMERGENCY STOP.
The switching status of the DCM signals correspondsto the logical machine processes. The interface
request by the ProDos DPC takes into consideration
these logical machine processes. In the event of discrepancies, dosing is halted, while a DCM positionerror warning is issued. Alternatively, the dosing isinterrupted and an DCM ERROR MESSAGE is issued.
A WESTOMAT dosing operation is only possible if the signal exchange with the DCM is properlyestablished.
The signals are designed as floating interrupters at asignal voltage of 24 V DC.
Certain die-casting machines are equipped withstandard optional functions that are integrated in theinterface signalling system. These signals are labelled
as op t i ona l in this description.

• DIE CLOSES ....................................... I-19
This signal switches in MANUAL, -AUTO and
AUTO mode of the DCM. as fol lows: I -19 = from 0 to1, if the closing of the movable die plate is started.
In MANUAL DOSING mode, I-19 is only queried inthe process of the logical switching sequence of thesignalled closing movement of the DCM die.
In AUTO DOSING mode, the switching of I-19 =from 0 to 1 initiates the following:
• Measuring of closing time (t 6) of the DCM die
• in AUTO-SYNCHRON-DOS: initiation of synchronization time (t1).
ATTENTION
After starting the ProDos DPC from BASICSTATUS to DOSING MODE, the switching status I-19 = 0 is checked and, if incorrect, position error I-19 = 1 is signalled.
The signalling of the start of movement of the dieplate is important in order to maintain the repeatedaccuracy of the closing time (t 6) of below 0.25sec.
During dosing operation AUTO DOSING ... RUN,the switching position I-19 = 1 is monitored: if I-19= from 1 to 0 after PRESSURE START and if I-20 /21 = 0, dosing is interrupted and DCMDISTURBANCE is signalled.
• kg-INCREASE (OPTIONAL) ........................ I-27
This signal switches in MANUAL, -AUTO and AUTO mode of the DCM. The signal is used for dieswith additional inserts. I-27 = from 0 to 1, if thecommonly used inserts are not used in this cycle:
• If the “normal” dosing volume in used in such acase, the sprue is reduced accordingly.
The ProDos DPC automatically takes this increaseinto account, if I-27 = from 0 to 1 prior to the start of the die closing (I-19 to I-23 = 0).
ATTENTION
In addition to the function of dosing volumeINCREASE, I-27 = from 0 to 1 discontinues AUTO-synchronization for the next two process steps(similar to I-25).

The signals switch in MANUAL, -AUTO and AUTOmode of the DCM.I-20 and 21 = from 0 to 1, when thedie plates are adjacent during the closing movement,i.e. when the shot sleeve is closed at the front.´
For reasons of safety, the closing status of the DCMdie is signalled via two separate channels: hardwarewith software query, and hardware only.
In MANUAL DOSING mode, I-20 and I-21 are onlyqueried in the process of the logical switchingsequence of the signalled closing movement of theDCM die.
In AUTO DOSING mode, the switching of I-20 / 21 =
from 0 to 1 initiates the following:
• Measuring of closing time (t 6) of the DCM dieis completed (repeatable accuracy of this time isless than 0.25 sec):
• in AUTO-SYNCHRON operation (with DCM-DIE CLOSED) = release of metal feed toshot sleeve
• Measuring of closing time (t 7) of the DCM dieis started.
ATTENTION
After starting the ProDos DPC from BASIC
STATUS to DOSING MODE, the switching status I-20 / 21 = 0 is checked and, if incorrect, positionerror I-20 / 21 = 1 is signalled.
During dosing operation AUTO DOSING ... RUN,the switch position I-20 / 21 = 1 is monitored, andif:
• At DC = start of metal feed I-20 / 21 = 0, dosing isinterrupted and DISTURBANCE DC BEFOREDCM-DIE CLOSED is signalled.
• If, after PRESSURE START, I-20/21 = from 1 to 0and I-22 / 23 = 0, dosing is interrupted andDISTURBANCE DCM is signalled.

• DIE READY FOR INJECTION 1 ................... I-22
• DIE READY FOR INJECTION 2 (OPTIONAL) I-23
The signals switch in MANUAL, -AUTO and AUTOmode of the DCM. I-22 and 23 = from 0 to 1, if theclosing section of the DCM is locked at the closingmovement.
For reasons of safety, the closing status of theDCM die is signalled via two separate channels,e.g. hardware with software query, and hardwareonly.
In MANUAL DOSING mode, I-22 and I-23 arequeried prior to release.
In AUTO DOSING mode, the switching of I-22 / 23= from 1 to 1 initiates the following:
• Measuring of t 7 of the DCM closing time iscompleted. The repeatable accuracy of this timeis between 0.5 and 2.5 sec:
• In AUTO-ASYNCHRON = PRESSURESTART for dosing
• In AUTO-SYNCHRON (with DCM-DIECLOSED) = release for continued injection
• In AUTO-SYNCHRON operation (with DCM-DIE READY FOR INJECTION) = release of metal feed to shot sleeve
• Measuring of t 8, injection stop time (from DCMdie ready for injection to release) is started
• After DOSING END, RELEASE FORINJECTION 1 / 2 are only completed, if I-22 / I-23 = 1
ATTENTION
After starting the ProDos DPC from BASICSTATUS to DOSING MODE, the switching status I-22 / 23 = 0 is checked and, if incorrect, positionerror I-22 / 23 = 1 is signalled.
During dosing operations MANUAL and AUTODOSING … RUN, the switching positions I-22 / I-23= 1 are monitored: if I-22 / I-23 = from 1 to 0,
dosing is interrupted and DCM DISTURBANCE issignalled.
