1 Self Contained Loader, Gravity Gate Discharge, Fill by Time: 
A call for material is established when the gravity gate swings closed. The LSR powers the self-contained vacuum motor and the loader fills by time. An alarm is generated if material reaches an optional high level sensor. After filling the loader dumps immediately via gravity discharge gate.
2 Self Contained Loader, Gravity Gate Discharge, Fill to Level: 
A call for material is established when the gravity gate swings closed. The LSR powers the self-contained vacuum motor and the loader fills to the high level sensor. An alarm is generated if material does not reach the high level sensor within the maximum fill time. After filling the loader dumps immediately via gravity discharge gate.
3 Single Central Receiver, Gravity Gate Discharge, Fill by Time:
A call for material is established when the gravity gate swings closed. The LSR controls the fill valve, vacuum breaker valve, and vacuum pump motor starter; the receiver fills by time. An alarm is generated if material reaches an optional high level sensor. After filling the receiver dumps immediately via gravity discharge gate.
4 Single Central Receiver, Gravity Gate Discharge, Fill to Level:
A call for material is established when the gravity gate swings closed. The LSR controls the fill valve, vacuum breaker valve, and vacuum pump motor starter; the loader fills to the high level sensor. An alarm is generated if material does not reach the high
level sensor within the maximum fill time. After filling the receiver dumps immediately via gravity discharge gate.

5 Self Contained Loader, Powered Gate Discharge, Fill by Time:
A call for material is established when the power gate closes. The LSR powers the self-contained vacuummotor and the loader fills by time. An alarm is generated if material reaches an optional high level sensor. After filling, the loader holds material until a refill request is received from equipment below (e.g. KCM).

6 Self Contained Loader, Powered Gate Discharge, Fill to Level:
A call for material is established when the power gate closes. The LSR powers the self-contained vacuum motor and the loader fills to the high level sensor. An alarm is generated if material does not reach the high level sensor within the maximum fill time. After filling, the loader holds material until a refill request is received from equipment below (e.g. KCM).
7 Single Central Receiver, Powered Gate Discharge, Fill by Time:
A call for material is established when the power gate closes. The LSR controls the fill valve, vacuum breaker valve, and vacuum pump motor starter; the receiver fills by time. An alarm is generated if material reaches an optional high level sensor. After filling,the receiver holds material until a refill request is received from equipment below (e.g. KCM).
8 Single Central Receiver, Powered Gate Discharge, Fill to Level:
A call for material is established when the power gate closes. The LSR controls the fill valve, vacuum breaker valve, and vacuum pump motor starter and the receiver fills to the high level sensor. An alarm is generated if material does not reach the high level sensor within the maximum fill time. After filling, the receiver holds material until a refill request is received from equipment below (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 predetermined times between 3 and 360 seconds.
