Honeywell TDC3000/Experion PKS: Combined with MU-PAIH03/MC-PAIH03 cards to build a high-density, high-reliability analog input system.

VII. Usage and Maintenance Instructions Instruction Manual

Installation: Install it in a standard control rack and fix it in place with the MU-PAIH03/MC-PAIH03 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, and check whether the connector contact is good.

Environmental maintenance: Keep the cabinet dry and dust-free, control the temperature within -20 ℃ to +60 ℃, and keep 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; module damage can be replaced online, and the configuration can be re-downloaded.

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