For Revisions 215 And Up

Definitions

NVRAM (Non Volatile Random Access Memory also known as Electronically Erasable Read Only Memory):
Memory area that can be modified during operation and retain that modified information after power is turned off
and on. The NVRAM is the area into which specific configurations are downloaded at the Pitco factory. Values are
also modified during normal operation and/ or strore-level programming.

RAM (Random Access Memory) memory that is populated on power up from the ROM (Read Only Memory) or
the NVRAM. Values are continually modified during operation but changes are not retained after power is turned
off and on.

Notes

1) RAM_Err (RAM error) indicates that corruption of the RAM has been detected on power up. If RAM_ Err is displayed,
further operation is inhibited unless error clears with turning power off and on.

2) NVM_Err (NVRAM error) indicates that the NVRAM write operation has failed. This error will change to CFG_Err upon
turning power off and on.

3) CFG_Err (Configuration error) indicates that corruption of the NVRAM has been detected. This error normally requires a
restore function to fix.

4) DFT_Err (Default error) indicates that illegal value of parameter in NVRAM has been detected on power up. If DFTJErr is
displayed alone (no associated CFG_Err), during operation, then a corruption of the RAM is indicated which will reset upon
turning power off and on.

General Information

All of these error messages will alternate with normal display except for the RAM_Err.
Any abnormal display or operation can occur if a noise event occurs which is large enough to cause a reset or

partial reset of the microprocessor. Turning power off and on should clear this type of fault.

Resetting Computer

An error reset attempt can be done by unplugging wiring harness on back of computer. If this does not reset
computer follow Factory Reset Instructions listed on page 15.

If computer will not reset replace computer

SECTION 1.2

1-12 COMPUTER REPLACEMENT AND

INSTALLATION INSTRUCTIONS

When replacing or installing the 1-12 (3600 Intellifry Computer) The computer must be
programmed to match the fryer the computer is being installed on. Note: This only
applies to Revision 207 computers and higher

If the computer is not configured to match the fryer it is being installed on improper
operation of the fryer may occur.

Remove old computer, inspect old computer for cause of failure, and ensure that front
panel components and wires are in proper order.

Install new computer and follow COMPUTER CONFIGURATION SETTING instructions
from page 12 and 13 of this manual.

Any abnormal display or operation can occur if a noise event occurs which is large enough to cause a reset or partial

reset of the microprocessor. Turning power off and on should clear this type of fault.

Resetting Computer

An error reset attempt can be done by SOFT OFF/ ON or by unplugging wiring harness on back of computer.
Unplugging computer is a more effective way to reset.

Note: If computer is on a split VAT, right side computer plug must be reconnected first, then left or computer will
not recognize there are 2 VATS. If this does not work reset computer following Factory Reset Instructions listed on
page 21.

If computer will not reset replace computer

SECTION 2.2

McDONALDS COMPUTER REPLACEMENT

AND INSTALLATION INSTRUCTION

When replacing or installing a McDonalds computer the new computer must be
programmed to match the fryer it is being installed on (Gas or Electric).

If the computer is not programmed to match fryer it is installed in improper operation may
occur.

Remove old computer, inspect old computer for cause of failure, and ensure that front
panel components and wires are in proper order.

Install new computer and follow FRYER TYPE instructions from page 21 of this manual.
