Symptoms

Image acquired without X-ray irradiation radiation

X-ray automatic detection sensor detects X-rays and acquires image when no X-rays are actually irradiated. Occurs when sensor is in Ready state and receives strong electromagnetic-wave noise and mechanical shock (vibration).

Ranked causes

1. Strong electromagnetic-wave noise in working environment (occasional)
2. Strong mechanical shock or vibration on sensor (occasional)
3. Another X-ray automatic detection sensor near irradiation field (occasional)

First check

Identify electronic equipment in working environment that may emit electromagnetic-wave noise

Test point: User's working environment
Expected: List equipment from attached table that may be noise source

CCS screen displays false X-ray detection message radiation

CCS screen displays message 'In spite of the fact that radiography is not yet ready, a signal of probable X-rays irradiation has been detected' when sensor is NOT in Ready state and receives strong electromagnetic-wave noise and mechanical shock.

Ranked causes

1. Strong electromagnetic-wave noise when sensor not ready (occasional)
2. Strong mechanical shock when sensor not ready (occasional)

First check

Verify sensor ready state status

Test point: Sensor control interface
Expected: Sensor should be in Ready state for normal operation

False X-ray detection message when sensor not ready radiation

CCS screen displays message indicating probable X-ray irradiation has been detected while sensor is not in Ready state

Ranked causes

1. Strong electromagnetic-wave noise when sensor not ready (occasional)
2. Strong mechanical shock when sensor not ready (occasional)

First check

Verify presence of strong electromagnetic-wave noise sources in user environment

Test point: User's working environment
Expected: No strong electromagnetic-wave noise sources present

Unintended X-ray detection when no irradiation present radiation

Sensor automatically detects X-rays and acquires image despite no X-rays being irradiated

Ranked causes

1. Strong electromagnetic-wave noise during Ready state (occasional)
2. Strong mechanical shock during Ready state (occasional)

First check

Verify presence of strong electromagnetic-wave noise sources in user environment

Test point: User's working environment
Expected: No strong electromagnetic-wave noise sources present

Unwanted image acquired without X-ray irradiation radiation

During X-ray automatic detection operation in Ready state, an image is acquired despite no X-rays being irradiated. System detects X-rays mistakenly.

Ranked causes

1. Strong electromagnetic-wave noise during Ready state (common)
2. Strong mechanical shock or vibration during Ready state (common)

First check

Verify absence of strong electromagnetic-wave noise sources in user's working environment

Test point: Installation location
Expected: No strong EM noise sources detected

False X-ray detection in ready state radiation

X-ray detector automatically acquires image despite no X-rays being irradiated when sensor is in Ready state

Ranked causes

1. Strong electromagnetic-wave noise combined with mechanical shock during Ready state (occasional)

1 corrective action and part numbers are in ServiceForge. Connect ServiceForge to your AI

False X-ray detection message when not in Ready state radiation

Ranked causes

1. Strong electromagnetic-wave noise and mechanical shock in non-Ready state (occasional)

First check

Identify strong electromagnetic-wave noise sources in user's working environment

Test point: User's operating location
Expected: No strong electromagnetic-wave noise sources present

1 corrective action and part numbers are in ServiceForge. Connect ServiceForge to your AI

Image acquired without X-ray irradiation during auto-detect radiation

X-ray automatic detection sensor mistakenly detects X-rays and acquires image when no X-rays are actually irradiated, occurring in specific working conditions

Ranked causes

1. Strong electromagnetic-wave noise and mechanical shock while sensor in Ready state (occasional)

First check

Verify user working environment for strong electromagnetic-wave noise sources

Test point: Work area
Expected: No strong electromagnetic-wave noise present

1 corrective action and part numbers are in ServiceForge. Connect ServiceForge to your AI

Image acquired without X-ray irradiation during automatic detection radiation

X-ray automatic detection sensor mistakenly detects X-rays and acquires an image when no X-rays are being irradiated, occurring in Ready state when sensor receives strong electromagnetic-wave noise and mechanical shock (vibration).

Ranked causes

1. Strong electromagnetic-wave noise and mechanical shock during Ready state (occasional)

First check

Identify strong electromagnetic-wave noise sources in user's working environment

Test point: User's operating location
Expected: No strong electromagnetic-wave noise sources present
