CAUTION
CAUTION:
Great care has to be used when switching the standard mode of operation to “Delayed
Transition”. In this mode, the controller will not synchronize the two sources.
Adequate time delay for the DW and DT timers has to be selected to make sure any
rotating loads have enough time to coast to a stop before selecting the Delayed
Transition mode. If this is not taken into account, severe damage to rotating
equipment can occur!
Understanding setpoints
Any of the ATS setpoints may be viewed or altered by pressing the Setpoints soft-key.
Setpoints data is divided into four pages.
•
Configuration page: Information about the ATS configuration as well as system setup,
inputs, outputs, communications, CTs, and VTs, events, and data log.
• Operation page: Information about the two power sources, such as failure points for
voltage and frequency, and failure time delays.
• Control page: Operator access to different modes of operation.
• Security page: Information about the security and password features.
Press the Setpoint soft-key to scroll through the setpoints pages. When pressed for the
first time, the following screen is displayed.
