Installation and safety regulations

1. Installation requirements

(1) Installation environment

Environmental conditions: Good ventilation, avoiding direct sunlight, heat sources, corrosive gases, strong electromagnetic fields, and severe vibrations; Horizontal installation (can tilt backwards ≤ 30 °)

Space restrictions: Avoid installation in civilian environments to prevent interference with other devices; The installation panel needs to meet the thickness requirements and reserve maintenance space

(2) Wiring specifications

Power wiring: Use 600V PVC insulated wire (AWG18) with a grounding resistance of ≤ 100 Ω; Separation of power lines from other lines ≥ 0.1m (recommended 0.5m)

Input wiring: It is recommended to use shielded wires. For TC/RTD wiring, attention should be paid to compensating wires and balancing the three wire resistance; The input terminal should be protected from exposure to airflow, and a transparent cover plate should be placed after wiring

Other wiring: alarm output, fault/paper out output, remote control wiring must follow the corresponding terminal definition, use shielded wire and ground correctly

2. Safety guidelines

Power safety: Confirm that the power supply voltage matches and prohibit the use of 132-180VAC power supply; Replacing the fuse requires using the specified specifications (such as 250V 750mA delay type) and power-off operation

Grounding requirements: Non portable models must be grounded, and it is prohibited to cut off internal or external grounding wires

Operation taboos: Do not operate in flammable liquid/vapor environments; It is prohibited to touch the inside of the device with electricity, and internal maintenance is only allowed to be carried out by professionals

Troubleshooting: In case of abnormal sounds, odors, or smoke, immediately turn off the power and contact the service center

Operation Process Guide

1. Preparation before startup

Open box inspection: Confirm that all accessories are complete (pen, ribbon, fuse, chart paper, power cord, etc.) and that there is no damage to the appearance; Verify that the nameplate model code matches the order

Unpacking operation: Open the front door, lift up the display screen, remove the transport fixing gasket, and close the display screen as required

Preheating requirement: Preheat for 30 minutes after startup, and may take longer for the first use after wiring

ERROR 011: The chart is exhausted and the chart paper needs to be replaced

ERROR 040: The reference channel number for the difference channel is incorrect and needs to be reset

ERROR 045: The left/right values of the recorded span are equal, and the span needs to be adjusted

ERROR 060: Attempting to set an alarm while skipping a channel, requires modifying the channel type

ROM/RAM/NV ERROR: System storage failure, please contact the service center

(2) Typical troubleshooting

Record no response: Check the power wiring, fuse status, and whether the record has been started; Still no response. Contact the service center

Large measurement deviation: Check the input range and span settings, wiring correctness, and grounding status; Check the ambient temperature and interference sources

Unclear printing: Replace the pen with a new one and check the tension of the ribbon in a dot matrix manner; Confirm that the chart speed is within the allowed printing range

No response to keys: Check the keyboard lock status, insert the key or disable the lock function in SET UP mode
