GENERAL OPERATION
RONK ATS GENERAL OPERATION
The ATS switch in combination with the controller module will
allow for the automatic transfer of an electrical load to a standby
power source in the event of an over/under voltage or frequency
condition on any or all phases of the utility power supply.
In the event of an over/under voltage or frequency condition of
utility power, the onboard controller sensing circuitry will begin
the initiation of the transfer process. Upon initial sensing of a
loss of utility power, the transfer switch is specifically designed
to allow an engine start time delay period (Parameter 502) to
expire before starting the generator. This engine start time delay
is user-adjustable from the switch, preventing unnecessary
engine starts from a temporary loss of utility. In the event the
utility source is not restored after the engine start time delay has
expired, the remote contacts will close, sending a signal to the
generator’s automatic start controller.
When the ATS controller senses that the generator has started,
and is within acceptable limits, the transfer switch will wait until
the utility to generator time delay (Parameter 503) has expired
before switching to the generator position. All connected loads
will be transferred to the generator power source.
While the transfer switch is in the generator position, the
controller will constantly monitor the utility source voltage
and frequency status. Once the utility source is restored, the
transfer switch will wait until the generator to utility time delay
(Parameter 510) has expired before switching back to the utility
position. All connected loads are transferred to the utility power
source.
When connected loads are transferred back to the utility power
source, an engine cooldown period (Parameter 511) will be
initiated, allowing the generator to run in a no-load condition.
This engine cooldown time delay is user-adjustable from the
controller, allowing the generator to continue running for an
adjustable period after the utility is restored.
