Carlo Gavazzi Monitoring Relay Generator Speed Din-Rail DFC02T724

Carlo Gavazzi Monitoring Relay Generator Speed Monitoring, Range: 20-450VAC / 4-100Hz, DIN-Rail, 3x SPDT, Supply: 24VDC.

Normal mode: If the generator isn't running all the relay are ON and the two-color LED is RED. As soon as the ignition speed (plus hysteresis) has been reached, the relay 1 turns OFF. If the speed is below the set level, relay 1 is turned ON. When the speed is above the lower setpoint,  (plus hysteresis) the relay 2 is OFF. If the speed is below the set level for more than the set delay time, relay 2 is turned ON. If the speed is above the upper level for more than the set delay time, the relay 3 is turned OFF. When the speed is below the upper setpoint (minus hysteresis), relay 3 is ON.

Reverse mode: If the generator isn't running, all the relays are OFF and the two-colors LED is red. As soon as the ignition speed (plus hysteresis) has been reached, the relay 1 is turns ON. If the speed is above the lower setpoint (plus hysteresis), the relay 2 is ON. If the speed is below the set level for more than the set delay time, relay 2 is turned OFF. If the speed is above upper level for more than the set delay time, the relay 3 is turned ON. When the speed is below the upper setpoint (minus hysteresis), relay 3 is OFF.
