Control Errors & Error Codes

Cryptic error codes on your booth? Here's how to decode them and what action to take.

What You're Experiencing

The paint booth control system is displaying error codes, fault messages, or alarm conditions that prevent normal operation.

Visual Signs:

  • Error code displayed on HMI or panel
  • Fault indicator lights active
  • Display showing alarm message
  • Equipment locked out due to error
  • System in fault/safe mode

Sound Signs:

  • Alarm buzzer sounding
  • Equipment not responding to commands

Safety Risks — Read Before Proceeding

critical(NFPA 33)

Ignoring safety-related error

Action: Safety errors (fire, airflow, interlock) must not be bypassed. Understand and resolve.

high

Process continuing in fault

Action: Some errors allow continued operation with degraded control. Understand implications.

Immediate Steps to Take

  1. 1

    Record exact error code or message

  2. 2

    Note which equipment is affected

  3. 3

    Check if error is safety-related

  4. 4

    Look up code in equipment documentation

  5. 5

    Check field devices associated with error

  6. 6

    Try clearing error only after understanding cause

  7. 7

    Document if error recurs after clearing

Common Causes

Here are the most likely reasons you're experiencing this problem, ranked by how often we see them.

Field Device Fault

common

A connected device (sensor, motor, valve) has a problem that's being reported.

Safety Condition

common

A safety interlock or protection has triggered (door, airflow, temperature, fire).

Process Limit Exceeded

occasional

A process parameter (temperature, pressure, time) has exceeded programmed limits.

Communication Error

occasional

Controller lost communication with a networked device or module.

Configuration Error

rare

Parameter or setting is incorrect or has been corrupted.

Is this a safety-related error (fire, airflow, interlock)?

If unsafe at any point: For safety-related errors that cannot be resolved, do not operate booth. Call WERCS at (877) 489-3727.

When to Call WERCS

While some issues can be resolved with basic troubleshooting, these situations require professional service:

  • Cannot find error in documentation
  • Error keeps returning after reset
  • Safety-related error
  • Multiple errors occurring
  • Need parameter adjustment
  • Error appeared after changes

Control Errors & Error Codes FAQ

Common questions about this issue

Check equipment manuals, control panel documentation, or labels inside panel doors. Many codes are standard for the controller platform. If code isn't documented, contact the equipment manufacturer or integrator.
Depends on error type. Process alerts may be OK to acknowledge after addressing. Safety errors need root cause fixed. Repeated resets cause error fatigue and missed real problems. Document everything.
Time-based errors suggest: scheduled operations, environmental factors (temperature, power demand), or process-related conditions. Track patterns. May indicate maintenance needed before daily startup.
Original programming by control system integrator or equipment manufacturer. Modifications require trained PLC programmers familiar with paint booth safety requirements. WERCS provides controls programming services.
