Auto Transfer Switch Control Module

This is an obsolete product, no longer available for purchase.

Features

The 530 is a fully configurable Automatic Transfer Switch control module. It is designed to monitor the
incoming AC mains supply (1 or 3 phases) for under/over voltage and under/over frequency. Should these fall out of limits, the module will issue a start command to the generating set controller. Once the set is available and producing an output within limits, 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 shut down the generator after a suitable cooling run. Various timing sequences are used to prevent nuisance starting and supply breaks.

Configuration is by PC based software and the 808 interface using an FCC68 socket on the rear of the module. This allows rapid and secure configuration of the module and also allows the 157 relay
expansion module to be utilised. The FCC68 socket also provides full real-time diagnostics of inputs and outputs.

Configuration and connection options allow for a wide range of higher functions such as ‘Auto start inhibit’, ’Manual restore to mains’, ‘Load inhibit’ (both mains and gen-set), ‘Lamp test’, Push-button transfer control, External mains or Gen-set failure inputs, etc.

The four position key-switch allows for mode selection:

AUTO MODE
AUTO MODE WITH MANUAL RETURN TO MAINS
RUN GENERATOR OFF LOAD
RUN GENERATOR ON LOAD

A clear mimic diagram, with International symbols and LED indications, provides ‘at a glance’ information as to supply availability and load switching status. Further LED indication is provided for ‘Start delay in progress’ and ‘Mains return timer active’.

Two user configurable LED’s are provided to allow the user to display specific states. Five user configurable relays are provided to allow control of contactors, different breaker types and engine control
modules and alarm systems. The module features a self seeking power supply which will utilise power from the Mains AC supply or the Generator AC supply. A DC supply to the module is not essential for basic operation, though some ‘higher’ functions require it (such as breaker tripping).

The module is mounted in a robust plastic case and connection is via plug and socket connectors.

DC SUPPLY

The 530 is normally powered from the AC sensing supplies. It will only draw power from the DC supply if both AC supplies are not present. The module DC is powered from the plant battery or from a low voltage supply between 8 V to 35 V Continuous. It is able to operate at 0 V for 50ms during cranking, providing supply was at least 10 V before dropout and supply recovers to 5 V. This is achieved without the need for internal batteries.

MAXIMUM OPERATING CURRENT
150mA @ 12V, 95mA @ 24V.

MAXIMUM STANDBY CURRENT
(AC POWERED SUPPLY)
35 mA @ 115V. 16mA @ 230V.
