The NEPEAN Power Belt Slip and Speed Monitor is designed to fulfill the needs of speed and slip measurement forconveyor systems. The Belt Slip Relay is compliant with AS/NZS 4024.3611:2015 which corresponds to “Safety of Machinery. Conveyors-Belt conveyors for bulk material handling. Clause 2.8.2.2”.

Slip Monitoring

• Measures slip between a belt speed (input S1) and two other driven rollers (inputs S2 & S3). Or the slip of one roller from its normal run speed
• Provides the maximum slip measurement (0-50%) on a 4-20mA output
• Provides a proximity sensor fault indication by closing the PROX fault relay output
• A fail-safe relay can provide a trip signal when slippage limits are exceeded

Speed Monitoring

• Measures and displays speed of up to three rollers (via proximity inputs)
• Provides the speed measurement (0-150% of normal run speed) on 4-20mA outputs (for remote monitoring)
• Provides a system healthy indication by closing the 80%-Relay after both start signal and 80% speed is detected
• Both under-speed and over-speed conditions can cause the fail-safe signal to trip
