Stop Transfer Test – Source 1 – Open Transition Mode (Retransfer from Normal 2 to split bus)
Press the Stop Source 1 Test button on the control screen of HMI. The system will initiate an open transition transfer, the Tie
breaker will open and after timer TDOX (3 sec) expires the normal main breaker 1 will close.
Start Transfer Test – Source 2 – Open Transition Mode
Press the Start Source 2 Test button on the control screen of HMI. The system will initiate an open transition transfer, the normal
main breaker 2 will open and after timer TDOX (3 sec) expires the tie breaker will close.
Stop Transfer Test – Source 2 – Open Transition Mode (Retransfer from Normal 1 to split bus)
Press the Stop Source 2 Test button on the control screen of HMI. The system will initiate an open transition transfer, the Tie
breaker will open and after timer TDOX (3sec) expires the normal main breaker 2 will close.
10.8.1.2 Optional Main-Tie-Main or Main-Main Configuration
Start Transfer Test – Source 1 – Closed Transition Mode
Press the Start Source 1 Test button on the control screen of HMI. The system will initiate a closed transition retransfer, (if, the
phase, voltage and frequency of sources are in synchronization). The tie breakers will close after timer TDOL (100 milliseconds)
expires the main breaker 1 will open.
Stop Transfer Test – Source 1 – Closed Transition Mode (Retransfer from Normal 2 to split bus)
Press the Stop Source 1 Test button on the control screen of HMI. The system will initiate a closed transition retransfer, (if, the
phase, voltage and frequency of sources are in synchronization). The normal main breaker 1 will close and after timer TDOL (100
milliseconds) expires the tie breaker will open.
Start Transfer Test – Source 2 – Closed Transition Mode
Press the Start Source 2 Test button on the control screen of HMI. The system will initiate a closed transition retransfer, (if, the
phase, voltage and frequency of sources are in synchronization). The tie breakers will close and after timer TDOL (100 milliseconds)
expires the main breaker 2 will open.
Stop Transfer Test – Source 2 – Closed Transition Mode (Retransfer from Normal 2 to split bus)
Press the Stop Source 2 Test button on the control screen of HMI. The system will initiate a closed transition retransfer, (if, the
phase, voltage and frequency of sources are in synchronization). The normal main breaker 2 will close and after timer TDOL (100
milliseconds) expires the tie breaker will open.
10.8.2 Main-Generator Configuration
10.8.2.1 Standard Main-Generator Configuration
No Load Test
Push the no load test pushbutton on the HMI screen. The system will initiate a generator start request. To stop test, push the no
load test pushbutton on HMI screen.
Load Test – Open Transition Mode
Push the load test pushbutton on the HMI screen. The system will initiate a generator start request. Once the emergency system
becomes available (at 90% rated voltage and frequency as indicated by the emergency source available light) the normal main
breaker will open and after timer TDOX (3 seconds) expires the emergency breaker will close.
Return from Load Test – Open Transition Mode (Retransfer from Emergency to Normal)
Push the load test off pushbutton on the HMI screen. The system will initiate an open transition retransfer, the emergency main
breaker will open and after timer TDOX (3 seconds) expires the normal main breaker will close. Once retransfer has occurred, the
generator start request will be removed and the cool down timer will begin timing (5 minutes).
Load Test (Exerciser On) – Open Transition Mode
Per the time and day set points on the HMI touch screen. The Exerciser will turn on and be on for the duration set point on the HMI
screen. The system will initiate a generator start request. Once the emergency system becomes available (at 90% rated voltage
and frequency as indicated by the emergency source available light) the normal main breaker will open and after timer TDOX (3
seconds) expires the emergency breaker will close.
