Selection Notes
Mainboard Selection
The CPM2X3 mainboard has multiple models, including I1, I2, HART, Profibus PA, and Profibus DP, etc. When selecting, it needs to be determined according to the fieldbus type and signal requirements.
Power Supply Module
The power supply module is divided into AC (51500317) and DC (51500318), and needs to be selected according to the power supply conditions.
Relay Module
The relay module is used to expand output contacts, available in 2-channel and 4-channel options, some with 4-20mA current input. When upgrading the LIQUISYS-M basic version, compatibility must be noted.
Software Upgrade Package
The software upgrade package can expand parameters and functions, such as pH, conductivity, temperature, chlorine, oxygen, etc., as well as cleaning functions. The instrument serial number must be provided when ordering.
Installation and Maintenance Recommendations
- Installation accessories such as the column mounting kit (50086842) are suitable for horizontal or vertical pipes with a maximum diameter of 60 mm, and the material is stainless steel V2A.
- Regularly check the ground terminal strip and cable connections to ensure signal stability.
- When replacing the mainboard or modules, pay attention to hardware version compatibility (such as H/W 2.10).
