Maintenance and Troubleshooting

Hardware Maintenance

Routine maintenance checks should be performed on the unit to  avoid  any risk of

 

hardware problems. The 

EZTouch I/O Flex

 is designed to be a very rugged controller 

so

 

that just a few checks periodically will help keep it up and running.

The key points to be checked include:

· Ambient operating conditions

· Wiring and connections

Maintaining the Ambient Operating Conditions

Keeping the 

EZTouch I/O Flex

 unit's  environment  within  specified  operating 

conditions

 

is the best method to minimize the maintenance.

1.

Always  ensure  that  ambient  temperature  inside  the  cabinet  is  within

EZTouch I/O Flex

 unit's temperature ratings.

2.

If  any  other  equipment  inside  or  outside  of  the  cabinet  is  producing  heat,

employ cooling methods  like  a  blower  fan  to  reduce  'hot  spots' around  the

EZTouch I/O Flex

.

3.

Periodically inspect and clean if there are any air filters on the cabinet. Ensure

that the unit is free from dust, humidity and corrosive gases.

Error Checking Process

The 

EZTouch  I/O  Flex

 performs a standard diagnostic routine during each  CPU 

scan.

 

This  is  called  the  error-checking  step.  The  primary  task  of  this  step  is  to 

identify

 

various types of CPU and  I/O failures. We classify these  errors/failures 

broadly

 

into two categories: Fatal and Non-Fatal.

Fatal Errors

These errors are the ones that lead to the system failure. During the CPU scan

 

if a fatal error is detected, PLC is automatically switched out of Run mode and

 

allI/O  points  are  disabled.  Some  instances  of  fatal  errors  include:  Wrong

 

parity value, Programming errors, etc.  The 

EZTouch  I/O  Flex

 will  not  go into 

Run

 

Mode from Program if it detects a fatal error.

Non-Fatal Errors

These  errors  just  need  your  attention  and  are  not  detrimental  to  PLC

operation.Unlike fatal errors, the PLC will continue in  Run  mode  despite  an

occurrence  of  non-fatal  errors.  When  you  identify  such  errors,  you  can

proceed  with  an  orderly  shutdown  and  take  the  required  corrective  action.

An example of non-fatal error is – a minor programming error.
