11.2.2 Gaining ECS Control
When attempting to gain ECS Control, there are three things that govern whether or not ECS Control can be
obtained:
1. LOC Priority.
2. LOC Lockout.
3. User profile access control.
11.2.2.1 LOC Priority
LOCs are assigned (through panel or SKSS-2 programming of the ECS-VCM or ECS-RVM) an LOC priority of
low, normal, or high. LOCs with a higher priority are always able to gain control from a lower priority LOC.
11.2.2.2 LOC Lockout
When LOCs are programmed to the same priority, the setting LOC lockout applies. LOC lockout will not allow
an LOC to gain ECS Control from the LOC with ECS Control until one of three things happen:
1. The LOC lockout timer expires. Once the LOC lockout timer expires, an attempt to gain ECS Control can be
made again.
Note: The lockout timer must be programmed to expire sometime other than Never.
2. The user at the second LOC requests ECS Control from the LOC with ECS Control and that LOC grants the
request. (See Section 11.2.7). If the ECS lockout timer expires while an ECS Control request is in progress,
the system will automatically pass ECS Control to the requesting LOC.
