Span Your Valves

If these are not your current values, we suggest that you correct them now
using the download procedure discussed in chapter 4.
Span Your Clamp Open Pressure Valve(s)
Span your clamp pressure valve for smooth operation at highest desired
clamp open pressure. Do this in the following procedure by finding
optimum values for:
Minimum Pressure Control Limit FOC41, SOC41, TOC41, and OSC41
Maximum Pressure Control Limit FOC42, SOC42, TOC42, and OSC42
Selected Pressure Valve, Output For Minimum
FOC43, SOC43, TOC43, and OSC43
Selected Pressure Valve, Output For Maximum
FOC44, SOC44, TOC44, and OSC44
Important: If your machine hydraulics are identical for all clamp open
and open slow profiles, complete the procedure for first clamp open by
finding values for FOC41-44, and copy them into the other clamp open
profile words SOC41-44, TOC41-44, and OSC41-44 when told.
Otherwise, repeat the procedure as needed.
Important: If PanelView is operational for clamp profiles, use it to:
observe actuals
change and download setpoints
run profiles
Important: We suggest that you read this procedure before starting.
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 to guard against personal injury.
1. Jog your clamp to the full open position.
2. Align all other machine hydraulics to simulate clamp open motion.
For example, enable required pumps and align required valves.
3. Copy initial values from FOC09-12 (N43:305-308) into DYC09-12
(N40:121-124) of your PLC-5 data table with this exception:
