Safety regulations and usage restrictions

1. Warning level and meaning

Example scenario of warning sign meaning

Danger (DANGER) Failure to take measures may result in death/serious personal injury. When the cabinet is electrified, it may open and come into contact with lethal voltage

Warning: Failure to take measures may result in death/serious personal injury. In explosion-proof areas, live plug and unplug connectors may cause explosions

Caution (CAUTION) Failure to take measures may result in minor personal injury, sharp objects scratching the touch screen

Caution: Failure to take measures may result in property damage, failure to follow the connection sequence, and equipment damage

2. Key safety requirements

Electrical safety: Only supports 24VDC power supply (voltage range 19.2V-28.8V) and must comply with SELV/PELV circuit requirements (IEC/EN 61131)

Use in explosion-proof areas:

Only Ex certified models are available for Zone 2/22 zones

Do not plug or unplug connectors or memory cards with power on

Ensure that the plug is secure against loosening (such as fixing the USB interface with a cable tie)

Environmental restrictions:

Only for indoor industrial use, prohibited for use in residential areas

Avoid high radio frequency interference (such as mobile phones), corrosive gases, and strong electromagnetic radiation

Equipment installation and connection

1. Key parameters for installation preparation

Prepare project requirements remarks

Installation opening size 4 “(KTP400): 122 × 98mm; 7” (TP700): 197 × 141mm, etc. Vertical installation requires exchanging width and height

Material thickness of 2mm-6mm ensures protection level of IP65

The heat dissipation gap should be ≥ 15mm on both sides, ≥ 50mm on the top and bottom, and ≥ 10mm on the back to avoid equipment overheating

Installation tilt angle: horizontal ± 35 °, vertical ± 35 ° (touch only). The 7 “-15” model can be extended to 40 ° under specific conditions

2. Connection sequence and specifications

Equipotential bonding: Use copper/galvanized steel wires with a cross-sectional area of ≥ 16mm ², and the wire between the grounding bar and the equipment should be ≥ 4mm ²

Power connection:

The power plug supports a maximum of 1.5mm ² wire and a torque of 0.5-0.6Nm

Equipped with reverse polarity protection to prevent damage to equipment caused by reverse connection

Controller connection:

Support SIMATIC S7-200/300/400/1200/1500 and third-party controllers (such as Allen Bradley)

PROFINET requires a unique device name to be configured, and PROFIBUS requires a bus address (1-126) to be set

Peripheral device connection:

USB devices (mouse/keyboard/printer): wire length ≤ 1.5m, USB 2.0 or above certification

Audio equipment: Connected through Line Out interface, production environment requires shielded cables

Equipment debugging and configuration

1. Core debugging function

Memory management:

Memory: stores OS, project files, licenses, prohibits circular write access

SD/MMC card: Recommended SIMATIC HMI storage card (≥ 2GB) for data archiving and backup

System memory card: only SIMATIC HMI card (≥ 2GB), supports automatic backup, quick fault recovery

Control panel settings:

Display settings: brightness (25% -100%), screen orientation (horizontal/vertical), touch screen calibration

Network settings: IP address (static/DHCP), PROFINET device name, NTP time synchronization

Security mode: Password protected control panel to prevent unauthorized modifications

2. Service and maintenance functions

Key points of functional operation

Backup/restore supports WinCC or ProSave tools, backup file format *. psb, including project, recipe, license

OS updates require external storage media or configuration PC, and automatic backup must be disabled before updating to avoid data loss

Automatic backup activated after inserting the system storage card, real-time synchronization of device data, and can be restored by inserting a replacement device in case of failure

Touch screen calibration uses a touch pen to calibrate 5 points, confirm and save within 30 seconds to ensure precise operation

Project commissioning and operation

1. Project transmission and testing

Transmission method:

Manual transmission: Select “Download to device” through WinCC and configure PROFINET/Ethernet channels

Automatic transmission: Used during debugging phase, it is recommended to disable it after commissioning to avoid accidental triggering

Test type:

Offline testing: Communication without controller, verifying interface layout and operational logic

Online testing: Connect the controller to verify measurement value updates, alarm triggering, and communication stability

2. Core operational functions
