MONITORING SYSTEM CMB-3 FOR SB AND SF BRAKES BRAKING UNLIMITED

MONITORING SYSTEM CMB-3 FOR SB AND SF BRAKES NEW FEATURES • Profibus or Profinet system possible • Automatic power supply range switch 110-240 V AC • One CMB-3 box can handle up to: - 2 brakes SB28 / SB23 / SB16 - 2 brakes SF10...SF40 - 1 dual caliper brake SF50 • Cable for sensors have a plug M12 on each end for easy troubleshooting • Same type of box for SF and SB brake types After many years of successful operation in the market, the brake condition monitoring systems CMB-2 have been improved. The new system CMB-3 can handle double amount of sensors. FEATURES • Industrial display with 4...

MONITORING SYSTEM CMB-3 FOR SB AND SF BRAKES 1. Parts of CMB-3 system for SB brakes If the minimum brake pad thickness is reached, the sensors (A) send a signal to the CMB-3. A pair of Pt100 sensors (B) measures the temperature of the each brake pad. If the temperature is too high or if the temperature is unequal from left to right side the unit generates a signal that is displayed in the panel. This error signal is given also on the Profibus / Profinet connection. Stroke sensor The analogue sensor measures the position of the thruster piston rod. The reserve stroke is measured and checked...

MONITORING SYSTEM CMB-3 FOR SB AND SF BRAKES Parts of CMB-3 system for SF brakes A pair of Pt100 sensors measures the temperature of the each brake pad. If the temperature is too high or if the temperature is unequal from left to right side the unit generates a signal that is displayed in the panel. This error signal is given also on the Profibus / Profinet connection. Temperature sensor Analogue sensors measure the stroke of each cylinder. If the stroke exceeds the maximum of 2.5 mm, a warning signal and an error message will be generated. The maximum measurement range is 3 mm. Analogue...

MONITORING SYSTEM CMB-3 FOR SB AND SF BRAKES All measured analogue signals, digital signals and error messages are shown on the display in English language. Other languages are available on request. The display is readable under direct sunshine and has a LED backlight for use in a dark environment, such as steel mills. With the internal keypad, the user can adjust parameters such as changing the temperature display from Celsius (°C) to Fahrenheit (°F) or setting of the Profibus address. The LED pushbutton on top of the electronic box indicates a wrong brake adjustment by a flashing red...
