Chapter 3 Connecting the System to the Mold
3.1 Prior to Start Up
●
Check that the system is completely disconnected from the power source.
●
Clean up any water, oil, dirt, cleaning fluids etc. that may have spilled during a mold change or since
the last production run.
●
Check all the cable connections between the system and the mold. Make sure all the cables are free
from wear or damage.
●
Check that the earth/ground connection is in good condition. Verify the system and the mold have
the same ground reference.
●
Check the output power and thermocouple wiring configuration on the mainframe and cable is the
same as on the mold.
●
Confirm that the sequential valve gate power output meets the requirement of the solenoid valves.
●
Confirm that the sequential valve gate trigger signal meets the requirement of the controller.
3.2 Verifying the Connection
1.
Connect the mold power and thermocouple cables.
2.
Connect the sequential trigger signal cable and output cable (if required).
3.
Using an Ohmmeter, touch one test lead to the mold and the other to the mold ground terminal on
the system. Resistance must be less than 1Ω.
4.
Check all the circuit breakers and make sure they are in the OFF position prior to connection of
the controller to the power source.
3.3 Startup Procedure Checklist
1.
Connect the mold power and thermocouple cables, sequential control cables between the mold
and controller (if required).
2.
Connect the controller to the power source.
3.
Switch the circuit breakers ON.
4.
Turn on the HMI, then select the language.
