Denotes that a failure to observe those instructions might cause damage to equipment or pose
NOTE: - Gives additional tips or instructions that might ease the job and ensure proper operation.
1.1. ABBREVIATIONS AND CONVENTIONS
Serial communication speed, in bits per second including start, parity and stop bits.
Cyclic Redundancy Check, additional bytes used to confirm valid data transmission.
IEEE 802.3, mostly referring to 10BASE-T RJ-45 connector present on board.
Differential pressure, often called Head.
A serial communication protocol used for device automation and remote access.
NMT pump Communication module.
Multi drop serial network wiring, used to transfer Modbus data.
For Modbus use, this manual assumes that the reader is familiar with commissioning and configuring of
Modbus devices. It is also assumed that an existing Modbus RTU network on RS-485 wiring with Modbus
master is present.
For Ethernet and web interface use, this manual assumes that the reader knows how to configure or already
has preconfigured Ethernet network.
For use of analog signals and relay output signals, external controller needs to be configured and used. Proper
operating mode must also be selected for the module.
NOTE:
• Data in this document are subject to change.
• Actual implementation might differ by pump model and software revision.
• Make sure you are using the right manual for your product.
• Verify proper operation in the final system.
• Manufacturer cannot be held responsible for problems caused either directly or indirectly by the use
of information in this manual.
2. INTRODUCTION
This manual describes the NMTC module for NMT range of pumps that is either integrated (NMT LAN C) or
separately (NMT Smart C and NMT MAX C) available. This module is used for various remote control
applications, including:
• Remote on/off
• Analog 0..10 V voltage control
• Modbus remote control
• Status relay feedback
• Web access over Ethernet
