1 Self-Contained Loader, Gravity Gate Discharge, Fill by Time:
A material call is triggered when the gravity gate swings shut. The LSR powers the self-contained vacuum motor, and the loader fills according to a timed cycle. An alarm is activated if the material reaches an optional high-level sensor. Once the loader is full, it immediately discharges via the gravity discharge gate.
2 Self-Contained Loader, Gravity Gate Discharge, Fill to Level:
A material call is initiated when the gravity gate swings shut. The LSR powers the self-contained vacuum motor, and the loader fills until it reaches the high-level sensor. An alarm is triggered if the material fails to reach the high-level sensor within the maximum fill time. Once the loader is full, it discharges immediately through the gravity discharge gate.
3 Single Central Receiver, Gravity Gate Discharge, Fill by Time:
A material call is initiated when the gravity gate swings shut. The LSR controls the fill valve, vacuum breaker valve, and vacuum pump motor starter; the receiver fills according to a timed cycle. An alarm is triggered if the material reaches an optional high-level sensor. Once filling is complete, the receiver discharges immediately through the gravity discharge gate.
4 Single Central Receiver, Gravity Gate Discharge, Fill to Level:
A material call is initiated when the gravity gate swings shut. The LSR controls the fill valve, vacuum breaker valve, and vacuum pump motor starter; the loader fills up to the high-level sensor. An alarm is triggered if the material fails to reach the high level.
Level sensor within the maximum fill time. After filling, the receiver discharges immediately via a gravity discharge gate.

5 Self-Contained Loader, Powered Gate Discharge, Fill by Time:
A material call is initiated when the power gate closes. The LSR powers the self-contained vacuum motor, and the loader fills according to a timed cycle. An alarm is triggered if the material level reaches an optional high-level sensor. Once filling is complete, the loader retains the material until a refill request is received from downstream equipment (e.g., KCM).

6 Self-Contained Loader, Powered Gate Discharge, Fill to Level:
A material call is initiated when the power gate closes. The LSR activates the self-contained vacuum motor, and the loader fills until it reaches the high-level sensor. An alarm is triggered if the material fails to reach the high-level sensor within the maximum fill time. Once filled, the loader holds the material in place until a refill request is received from downstream equipment (e.g., KCM).
7 Single Central Receiver, Powered Gate Discharge, Fill by Time:
A material call is initiated when the power gate closes. The LSR controls the fill valve, vacuum breaker valve, and vacuum pump motor starter; the receiver fills according to a timed schedule. An alarm is triggered if the material level reaches an optional high-level sensor. Once filling is complete, the receiver retains the material until a refill request is received from downstream equipment (e.g., KCM).
8 Single Central Receiver, Powered Gate Discharge, Fill to Level:
A material call is initiated when the power gate closes. The LSR controls the fill valve, vacuum breaker valve, and vacuum pump motor starter, and the receiver fills up to the high-level sensor. An alarm is triggered if the material fails to reach the high-level sensor within the maximum fill time. Once filling is complete, the receiver retains the material until a refill request is received from downstream equipment (e.g., KCM).
9 UnLoader (Self-Contained or Single Central):
Switches the self-contained vacuum motor or vacuum pump motor starter on and off for predefined durations ranging from 3 to 360 seconds.
