3.4 Wiring Check
CAUTION
System Mains Supply Wiring:
• Before connecting the system to a power supply, it is important to check that the wiring
between the system and the power supply has been done correctly.
• Particular attention must be given to the current rating of the power supply. For
example, if a controller is rated at 63A, then the power supply must also be rated at
63A.
• Check that the phases of power supply are wired correctly.
Controller to Mold Wiring:
• For separate power and thermocouple connections, ensure that the power cables are
never connected to the thermocouple connectors and vice-versa.
• For mixed power and thermocouple connections, ensure that the power and
thermocouple connections have not been wired incorrectly.
Communications Interface and Control Sequence:
• It is the customer’s responsibility to verify functionality of any custom machine interface
at safe speeds, prior to operating equipment in the production environment at full
speed in automatic mode.
• It is the customer’s responsibility to verify all required motion sequences are correct,
prior to operating equipment in the production environment at full speed in automatic
mode.
• Switching the machinery into Auto mode without having verified the control interlocks
and motion sequence are correct, may cause damage to machinery and / or
equipment.
Failure to do wiring or connections properly will result in equipment failure.
CAUTION
The use of Mold-Masters standard connections can help to eliminate the potential for wiring
errors.
