Control System Operations Manual AGE Page 9 of 129
The new Coral Sea control system incorporates the very latest in powerful control system technology as
well as highly intelligent programming. At the core of the control system is the all new 32 bit
Programmable Logic Controller (PLC); this device provides constant supervision of your water maker.
Should any problem arise during operation this intelligent hardware will first analyze if this fault could
possibly damage the water maker, if so it classifies this error as ‘critical’ and shuts the unit down to
prevent damage. However, if the controller deems the current problem as ‘non critical’ the water maker
is allowed to continue operating; meanwhile the control system will alert operators that service is
required by beeping and displaying a warning notification on the system touch screen; the controller will
continue to monitor the situation closely and if the current problem should become ‘critical’ the control
system will take action to prevent damage and shut the water maker down. The reason for the
shutdown will be displayed on the system touch screen.
The new Coral Sea controller has also been designed to ensure maximum water maker productivity; the
system contains multiple programs to allow for operation even in ‘critical’ fault situations, ensuring that
whenever possible your water maker can produce the water essential for survival. Please see
“emergency operations” section for further details.
This manual has been written to help walk you through the various features offered by the installed
control system. During fault situations your water maker control system produces messages to help
point you to the problem; contained within this manual is a list of trouble shooting tips based on these
messages; each tip will detail the likely possibilities which resulted in the call for the associated fault
message.
The new Coral Sea control system also comes with an available Modbus interface. This Modbus interface
can be used to create an open communications interface between locally hosted control systems and
the Coral Sea water maker. Via the Modbus interface it is possible to monitor all control system inputs
and outputs; it is also possible to monitor data normally displayed on the control system touch screen
including alarm information, performance information, system pressure information and salinity
information.
For further information on the Modbus interface, please refer to the Coral Sea Modbus Specification
documentation.
