VII. Usage and Maintenance Instructions Instruction Manual

Installation: Install it in a standard control rack and fix it in place with the HLAI card. It supports hot swapping. Before installation, confirm that the rack slot is compatible.

Wiring: The positive and negative terminals of the on-site instrument correspond to the terminals. The shielding layer is grounded at one end to avoid circulating interference. The terminals should be tightened without any looseness.

Configuration: Configure the channel range and signal type through the engineer station, and after downloading the configuration, data can be collected.

Maintenance instructions:

Regular inspection: Check the terminal tightening and whether there is corrosion or oxidation on the wiring every quarter. Check whether the connector contact is good.

Environmental maintenance: Keep the cabinet dry and dust-free, with a temperature controlled at -20 ℃ to +60 ℃. Stay away from strong electromagnetic interference sources.

Fault handling: When there is an abnormal signal, first check the terminal wiring and shielding grounding, then check the connection status between the connector and the main control card. If the module is damaged, it can be replaced online and the configuration can be re-downloaded.

Storage: Place the spare terminal board in a dry and cool place, at -40 ℃ to +85 ℃. Avoid heavy pressure and severe vibration.
