CRANE SOFTWARE INSTALLATION
If needed, contact your Manitowoc dealer or Crane Care in
Manitowoc for detailed instructions for installing crane
software and capacity chart files.
CPU AND EPROM COMPATIBILITY
Faulty central processing units (CPU) in the field are
replaced with new CPU 366113 which will work in any
Manitowoc EPIC controlled crane with a 5-plug Eder CPU.
The new CPU requires 150 nano second EPROMs (chips).
Past production 200 nano second chips cannot be used
in a new CPU; crane will not operate properly.
The new CPU does not include chips. When ordering a new
CPU check the existing chips on your crane to determine if
you already have 150 nano second chips (see chip
identification below). If not, you must order new chips
programmed for your crane.
1. The 150 nano second chips will work in any Manitowoc
EPIC controlled crane with a 5-plug Eder CPU, as long
as the chips are programmed for the specific crane.
2. The Model 777 must be replaced with CPU 366113 and
150 nano second chips.
3. New chips sent to you from Manitowoc will be 150 nano
second speed and not require identification. The chips
will work in any Manitowoc EPIC controlled crane with a
5-plug Eder CPU, as long as the chips are properly
programmed.
EPROM (CHIP) IDENTIFICATION
There are 4 brands of 150 nano second chips that will work
with CPU 366113 or CPU card 366116: AMD, Fairchild,
Tompson, and Texas Instruments. All of these chips are
available from Manitowoc.
To identify a chip, remove the label from the top of the chip.
Do this to one chip at a time so they do not get mixed up. Be
sure to reinstall label over window in chip. They are light
sensitive.
AMD – Hold the AMD chip with the notch to the top. The
word MALAYSIA will appear on the top surface near the
notch. Below the window, an 8-digit code will appear in the
first line and –150 must appear in the second line.
Fairchild – Hold the Fairchild chip with the notch to the top.
The chip will be blank above the window. Below the window,
F and a 7-digit code will appear in the first line, a 10-digit
code will appear in the second line, and 150 will appear in
the third line.
Texas Instruments – Hold the Texas Instruments chip with
notch to the top. The chip will be blank above the window.
Below the window, the Texas Instruments symbol and a 5-
digit code will appear in the first line and a 6-digit code
followed by –15 will appear in the second line.
Thompson – Hold the Thompson chip with the notch to the
top. The chip will be blank above the window. Below the
window, an 8-digit code will appear in the first line and –15
will appear in the second line.
If you have questions regarding chip identification, please
contact your Manitowoc dealer.
