Before proceeding, observe these warnings:
ATTENTION: As with any machine start-up, install a test
mold. Programming errors, configuration errors, or hydraulic
problems could lead to personal injury and/or machine damage.
ATTENTION: Be sure all machine guards and shields are in
place before proceeding.
ATTENTION: Load the hopper with plastic before starting this
procedure. Absence of plastic during plastication:
nullifies this procedure
may cause excessive wear to the barrel and ram (screw)
Span Your Plastication RPM Valve
Span your plastication RPM valve for smooth operation at the highest
desired RPM. Do this by finding the optimum values for these words:
Minimum RPM Control Limit PLC45 (N44:401)
Maximum RPM Control Limit PLC46 (N44:402)
Selected RPM Valve, Output for Minimum PLC47 (N44:403)
Selected RPM Valve, Output for Maximum PLC48 (N44:404)
Important: If PanelView is operational, use it to:
observe actuals
change and download setpoints
run profiles
Important: We suggest that you read this procedure before starting.
1.
Manually jog your ram (screw) to a point near the mold-end position.
2.
Align all other machine hydraulics to simulate plastication:
enable pumps and align valves to their normal plastication state.
