Nameplate
Every Master Station includes a nameplate detailing serial number and model number. The serial number uniquely identifies the Master
Station and can be used by the Rotork factory to trace the manufacturing details of the unit. This is a useful reference for upgrades
and spares enquiries. The model number defines the build configuration of the Master Station, whether it is hot standby, dual or single
configuration, the power supply rating, how many FCUs can be connected and which Add In Modules (AIMs) are fitted.
