1/2 <strong>DIN</strong> <strong>Process</strong> <strong>Control</strong>lerC501SS/C501_5Customized Application TemplatesTemplates are provided to make the basic configuration for aparticular application as simple as possible. When a template isselected the C501 assumes the preset form for that template(see below). The inputs and software blocks are soft-wiredautomatically to perform the selected function.Configuration time is greatly reduced as 90% of the choices youwould normally need to make in similar products are alreadypreconfigured.The C501 offers the following templates:1 Single loop controller with local set point2 Single loop controller with remote set point3 Auto manual station (low signal detection)4 Auto manual station (digital signal selection)5 Analog backup station (low signal detection)6 Analog backup station (digital signal selection)7 Single indicator/manual loader station8 Dual indicator/manual loader stationSequencing and Logic <strong>Control</strong>The C501 offers comprehensive sequencing, to complement itsadvanced analog control features, and six logic equations, withup to fifteen elements per equation. These logic equations, whencombined with delay timers, real-time alarms and extensive I/O,make the C501 a powerful interlocking controller.ABCDA . BC . DQ = (A . B) . (C . D)Intelligent Adjustable Power RecoveryTwo forms of plant power failure recovery are availableprogrammable between 0 and 9999s for recovery time:‘HOT’ restart – if the power is restored within the recovery timethe C501 defaults to Auto mode, allowing the process to be upand-runningwithout delay.‘COLD’ restart – if the power is not restored within the presetrecovery time, the controller defaults to Manual mode, or apredetermined control output. This ensures that after powerfailure the controller does not start to control the process withoutoperator acknowledgment.Industrial Robust DesignThe front face has been designed to meet IP66/NEMA4X ratingwith a unique moulded case and panel seal. A chemical resistantpolyester front panel ensures a secure investment for anyenvironment.Single Loop <strong>Control</strong> Template – ExampleSteamLocal Set PointLSPtLLRSteamConstant HeadReservoirRemote Set Point InputIP2RSPtWater/SteamInterfaceLTDrum LevelTransmitter<strong>Process</strong> Variable InputIP1CSPtPVPID<strong>Control</strong> LoopPID O/PWater withSteam BubblesBoilerDrumI/PFeedwater<strong>Control</strong> ValveFeedwater<strong>Control</strong> OutputOP1Manual Output6
