CHAPTER 7 SWING ARM SETUP AND OPERATION (EXCLUDING SMP)
7.1 OVERVIEW
Note: On the MultiLoad II SMP, swing arm operation is not possible.
A swing arm is mounted on an island and can be pulled to either of the two bays adjacent to the island.
On MultiLoad II, up to 12 swing arms can be assigned to a bay. A bay can have any combination of fixed load
arms and swing load arms, provided the total number of load arms does not exceed 12 per bay.
The two bays served by a swing arm will each have an MultiLoad II RCU. Inputs and outputs associated with a
swing arm's flow meter and control valve must reside on an external FCM(s) that are common to both MultiLoad II
RCUs. This FCM will receive the flow meter(s) input and operates the control valve(s) for this swing arm and will
communicate with the RCUs of both bays, but not simultaneously. A swing arm detector switch and a relay are
used to make the appropriate communication connection between the swing arm FCM(s) and the selected bay
MultiLoad II RCU. Each swing arm will employ two detector switches and one switching relay.
Please see Figure 7.1.
