PBM B (Base Module) - MOTOR MANAGEMENT SYSTEM

Fanox PBM Monitoring, Control and Protection System brings an integral solution to Motor Control Centers. PBM B base module can work standalone or together with the PBM H interface.

Current measurement, from 0.8 up to 25 A, is obtained from the motor line through PBM B’s magnetic module without need of external current transformers. Over 25 A, use external current transformers*.

PROTECTIONS

• Overload with thermal image.
• Overheating protection (PTC sensor).
• Phase imbalance or phase failure.
• Phase sequence.
• JAM detection.
• Locked rotor detection.
• Instantaneous earth leakage overcurrent.
• Earth leakage inverse time overcurrent.
• Instantaneous neutral overcurrent.
• Neutral inverse time overcurrent.
• Undercurrent.

FAULT REPORTS

• Four fault reports with the following information: dates, measurements, status bits, inputs and outputs.

SELF-DIAGNOSIS, INSTALLATION MONITORING AND STATISTICS

• Earth toroidal disconnection monitoring.
• PTC sensor open circuit and short circuit detection.
• Magnetic module hardware monitoring.
• Non-volatile memory stored information coherence.
• Number of motor start-ups.
• Medium and maximum current of last start up.
• Number of faults for the following functions:
• Overload, PTC, JAM, locked rotor and neutral faults.
• Operating hours counter.
• Test menu.

DESIGNED FOR SCADA APPLICATIONS

• RTU Modbus protocol and RS485 communication.

COMMANDS MANAGEMENT

• Start/Stop by 2 or 3 wires, without additional switches of push-buttons.
• Remote Start/Stop, more efficiency and cost saving.

COMMUNICATION SOFTWARE PBCom

The PBCom PC software is used to communicate with Fanox PBM Motor Protection Relay. Software is designed to gain access to PBM relay information, to modify the settings, check states and measurements and to analyse and save events and fault reports using a graphic-friendly user interface.

The main operations that can be carried out using the PBCom software are as follows:

• General data reading: Complete model, Version, Serial number, etc.
• States reading.
• Measurements reading.
• Reading and changing settings.
• Reading fault reports.
• Changing the user passwords.
• Saving and Loading settings files.
• Saving fault reports.
• Date-time synchronization.
• Configuring the communication parameters.
• Reading and changing counters.
• Commands for erasing the thermal image.

It allows the user to prepare all the settings and relay configurations without having the relay connected to the PC (offline mode), reducing engineering and commissioning time. PBCom software uses Modbus protocol, so ports with this protocol are required to establish the communication.

* Fanox offers a wide selection of current transformers.
