No Load Test (Exerciser On)
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. A start signal will be sent to the generator.
Return from No Load Test (Exerciser Off)
Per the time and day set points on the HMI touch screen. The Exerciser will turn off after the duration time set point has expired. The
generator start request will be removed and cool down timer will begin timing (5 minutes).
Retransfer Inhibit (Maintain Emergency)
To inhibit retransfer, push the inhibit pushbutton on the control screen of HMI. The home and control screen will indicate retransfer
is inhibited. The system will remain on emergency system until the bypass pushbutton on the HMI is pressed or until retransfer
mode is put back into auto by pressing auto pushbutton on the control screen of the HMI.
10.8.2.2 Optional Main-Generator Configuration
Load Test – Closed Transition Mode
Push the load test pushbutton on the HMI screen. The system will initiate a closed transition retransfer, (if, the phase, voltage
and frequency at generator are in synchronization with that of utility) the emergency breaker will close after timer TDOL (100
milliseconds) expires and the normal main breaker will open. Return from Load Test – Closed Transition Mode (Retransfer from
Emergency to Normal).
Push the load test off pushbutton on the HMI screen. The system will initiate a closed transition retransfer, (if, the phase, voltage
and frequency at generator are in synchronization with that of utility) the normal main breaker will close after timer TDOL (100
milliseconds) expires and the emergency breaker will open. Once retransfer has occurred, the generator start request will be
removed and cool down timer will begin timing (5 minutes).
Load Test (Exerciser On) – Closed 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 closed transition retransfer, (if, the phase, voltage and frequency at generator are in
synchronization with that of utility) the emergency breaker will close and after timer TDOL (100 milliseconds) expires the normal
main breaker will open.
Return from Load Test – Closed Transition Mode (Exerciser Off)
Per the time and day set points on the HMI touch screen. The Exerciser will turn off after the duration time set point has expired. The
system will initiate a closed transition retransfer, (if, the phase, voltage and frequency at generator are in synchronization with that
of utility) the normal main breaker will close after timer TDOL (100 milliseconds) expires and the emergency breaker will open. Once
retransfer has occurred, the generator start request will be removed and cool down timer will begin timing (5 minutes).
Return from Load Test – Open Transition Mode (Retransfer from Emergency to Normal)
Per the time and day set points on the HMI touch screen. The Exerciser will turn off after the duration time set point has expired. 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 cool down timer
will begin timing (5 minutes).
