Operating Guidelines

3-11

Counters

The CHI control panel can display counts of 

flatwork pieces processed in a variety of manners, 

from  individual  item  counts  to  total  pieces 

processed by the machine.

For  a  detailed  explanation  of  each  counter 

display and how to reset counters, refer to the 

CHI PANEL OPERATION

 bulletin, 

Operation

 

section, 

Counters

 subsection.

Self-Diagnostics

The Air  Chicago  folding  control  system 

continuously  monitors  itself  for  sensing  and 

folding errors. If an error is detected, a flashing 

message appears in the CHI panel display and an 

audible alert is heard.

PRIMARY FOLD FAILED

(TOO WIDE FOR CROSSFOLD)

The problem should be addressed immediately, 

and  if  necessary,  be  brought  to  the  attention 

of maintenance or service personnel. The fold 

system may still be operational depending upon 

the nature of the error and where it occurred.

Programming, Adjustment, Testing

The folder’s operations are centrally operated 

through  the  CHI  (Chicago  High  Intelligence) 

control panel. The CHI Panel makes it easy to 

operate,  program,  adjust  and  test  the  folding 

system.

The  unit  is  pre-programmed  at  the  factory 

to accommodate standard flatwork sizes and to 

automatically determine the number of primary 

and/or crossfolds necessary to result in a neat, 

stackable package. However, the unit can also 

be  reprogrammed  to  handled  small  and  large 

flatwork pieces as desired.

In addition, various specific settings in each 

section of the Air Chicago fold system can be 

electronically adjusted to deliver accurate and 

consistent packages. These include delays and 

timings in each folding station of the primary and 

crossfold sections.

Finally, the fold control system allows service 

personnel to test the various sections of the fold 

system  to  ensure  they  are  operating  properly. 

Each section is individually selected for testing.

For complete details, refer to the
