PAT Modular PDC Load Moment Indicator Service Manual

An LMI like the PAT modular PDC watches crane loading and compares it against the rated limits. When a board fails or the software needs a change, the person at the bench is usually a service tech or a shop owner working out of warranty. They need to know which board is which and how to get the system back up.

What this manual helps you do

• Identify which plug-in board sits in which slot of the computer, using the board assignment section.
• Check the layout of the CPU board and the LLD board before you start probing.
• Trace the analog input board and the analog basic and piggy output boards when a channel isn't behaving.
• Verify the digital basic and piggy input and output boards against their layout pages.
• Follow the steps for changing the software, and use the PDC – Tool section when you connect to the system.

Who this is for

Crane service technicians, rental fleet mechanics and independent repair shops that open up PDC computers themselves. It also suits anyone who inherited a crane with an LMI and no paperwork for it.

FAQ

Q: What do I receive and how is it organised?

Q: Which equipment does it fit?

A: It is the PDC Modular System Service Manual for the PAT modular PDC load moment indicator. If your crane runs that system, this is the book for the computer and its boards.

Q: How does it fit my repair job?

A: It is a short component service manual, and it is complete. You get the board layouts, the slot assignment, the software change procedure and the PDC – Tool section in one file you can keep on the bench laptop.
