3.5.3.1. SERVICE ENTRANCE ATS
Service Entrance rated ATS’s provide a manually initiated operation sequence which
signals the ATS mechanism to transfer from either connected source to the neutral
position to de-energize the ATS Load. This operation mode is activated by the Service
Disconnect control switch. Once in the Service Disconnected mode, the TSC 7320’s
transfer control outputs and engine start circuits are disabled. When the Service
Disconnect control switch is de-activated, the ATS will transfer back to the available
source to re-energize the ATS Load.
NOTE: the TSC 7320 programmable digital input for Service Disconnect mode must
be used in conjunction with a Service Disconnect control switch which changes the
source of control power to the TSC 7320 output contacts to enable transfer to the
neutral position.
NOTE
The controller will stay in Stop mode after moving the service
disconnect switch back to the Energized position. To resume
normal operation the user must press the auto mode button when
done.
