ATI RANGE
Load Transfer Panel
Olympian Generating Sets introduces a new
range of intelligent load transfer panels, which
operates in conjunction with our autostart
genset control panels and incorporates the latest
state of the art control technology.
The panels use a mechanically held motorised
switch to transfer the load between the mains
and the genset and vice versa. In the event of
mains failure, the control logic will automatically
start the genset and transfer the load. The
connection between the control panel and
the ATI panel incorporates a two wire control
system.

The motorised switch can also be manually
operated in the event of failure of any other part
of the system. A further benefit of the switch is
that it will remain mechanically held in position
despite any fluctuations in supply. In addition,
should maintenance be required on the control
system, the switch will stay in position and can
be operated manually.
The electronic control module is situated on the
front of the unit. The module will operate with
any three phase voltage from 190 to 480 volts
(50 or 60 Hz), with easy conversion to single
phase operation.
All models have been designed with customer
accessibility in mind, boasting features such as
a removable front cover, entry gland plate, cable
access plate and a removable control module
and/or motor.
