The following additional modules can be added as options via the CAN bus:
• CAN/USB.
• C2CLOUD (GPRS and eet manager).
• CAN/485 (MODBus).
• CAN2LAN.
• CAN2LAN (MODBUS IP).
• CAN2LAN HG FLEET MANAGER.
• CAN2LAN (SNMP).
1.1 MEASUREMENTS MODULE
The measurements module provides the following electrical signal characteristics,
both those generated and those from the network itself:
• Phase-neutral voltage.
• Phase-to-phase voltage.
• Current phase.
• Frequency.
• Active, apparent and reactive power.
• Power factor.
• Genset instant energy (kWh).
• THD (total harmonic distortion) of voltages and currents
• Calculation of harmonics up to order 20.
The measurement module provides the following electrical panel control
functions:
1. Electrical panel alarm inputs:
• Emergency stop (mushroom head stop button).
2. Congurable inputs; the measurements plate has 3 inputs that can be
programmed to perform the following functions:
• Network contactor con rmation.
• Con rmation of genset contactor.
• Enabling of genset breaker activation.
The measurements module has relay outputs to command activation of network
and genset contactors. It also has a relay to command the start-up of genset via
voltage free output.
The connection of the measurements module and display module is performed
via a CAN communications bus, enabling the interconnection between additional
modules which ensures the scalability of the control unit.
