C-2 Preventive Maintenance Monitor
How the PM Monitor Works
In the previous example, the SmartPAC 2 PM monitor would keep track of machine stops and
could be set to signal a PM alert for the braking system after 50,000 machine stops, for
example. If the press is idle or running coil fed jobs, the time between alerts will be long. If
the press is used for hand-fed jobs, the time between alerts will be shorter.
Up to 64 items can be set up in the PM Monitor's schedule. Tracking units such as machine
starts or stops, strokes, motor-on hours, cam channel actuations, die changes, tonnage
overloads, etc. (depending on how SmartPAC is configured), can be assigned to each item in
the schedule. The PM Monitor can also track hours, days, weeks and months for items that
need to be maintained according to a specific time schedule. A
tracking frequency is
assigned to each item to tell the PM Monitor when to signal an alert. At that time, an alert
message appears in SmartPAC's status bar in Run mode.
The entire PM schedule can be viewed in Run mode. The schedule shows each item, its units,
frequency, and current value. Any items in alert status are highlighted. Items with alert
status will be highlighted until the alert is cleared and the item is reset. The PM monitor
continues to track alerted items until they are reset. Please note that SmartPAC does not stop
the press when an item is in alert status. SmartPAC's PM schedule is password-protected to
keep unauthorized personnel from clearing an alert.
Examples of How to Use the PM Monitor
Some examples to help you properly set up your PM monitor are provided in Table C-1 and
Figure C-2, page C-3, which show “PM items” and “PM tracking units.” If you do not find a
suitable PM item name, you can program in a “custom” name to match your application.
Examples below provide such “custom” suggestions. To obtain further assistance in using the
PM Monitor, contact Wintriss Tech. Support.
The tracking unit “ Ch. cycles ” (for cam channels 1 through 8 or 16
2
), can be used to track the
usage of various ancillary devices controlled by SmartPAC. Some PM items might include:
feeder, pilot release solenoid, and ejection cylinders.
The tracking unit “ Die changes ” can be used to track the usage of components that are
directly related to changing tools at SmartPAC. Some PM item examples might include:
hydraulic clamping mechanism and the ram adjust motor.
“ F## ” WPC press control faults can be used to monitor items connected to the user-definable
inputs set when SmartPAC is integrated with the Wintriss Clutch/Brake Control (WPC). Here
are some examples: lube pressure, lube level, Nitrogen pressure (related to Nitrogen die
spring systems).
