The 500 is an automatic transfer switch control module.
It is designed to monitor the incoming AC mains supply (3
phases) for under voltage. Should this fall out of limits the
module will issue a start command to the generating set
controller. Once the set is available the ATS module will
control the transfer devices and switch the load from the
mains to the generating set. Should the mains supply
return to within limits the module will command a return to
the mains supply and stop requesting the generator.
A clear mimic diagram with ‘International' symbols and
LED indications provide ‘at a glance' information as to
supply availability and load switching status.
In the even of a Mains failure the module operation would
normally be as follows:-‘Mains available' LED extinguishes and the module de-energises
the ‘Run Generator' Relay, causing the ‘Run'
contacts to close. A generator start module receives this signal
and initiates the engine start.
