Essential details：323174-01 ADAPT (ESD) Emergency Shutdown Device
The 3701/55 Emergency shutdown Device, (ADAPT ESD) is asafety PLc with a graphical logic programming interface andintegrated overspeed detection. ADAPT ESD is designed foremergency shutdown of rotating machinery such as steamgas, and hydro turbines, expanders, and other processequipment.
ADAPT ESD is a compact, standalone, triple-redundant, safetyshutdown device that is designed to meet a broad range ofuser scenarios and applications. The design offers anelectrical and mechanical package with attention toreliability and availability as well as extensive self-diagnosticsand compliance to industry standards.
Inputs
Inputs to the system are processed using three CPU modulesto provide triple modular redundancy (TMR). Each CPUprocessing module processes two unique speed inputchannels, for a total of six speed channels for the system. Theprocessing modules also monitor an array of 32 discrete (Dl)and process variable (PV)signal inputs. Twelve channels ofthis input signal array may be configured either as discreteinputs or 4-20 mA analog inputs. Remaining channels in thearray are reserved for discrete input signals only.
Outputs
Machinery shutdown functionality of the 3701/55 ADAPT ESDsystem is actuated by TR relay output modules. Each relayoutput module has five relays with a level of configurabilitythat accommodates a variety of applications andrequirements. Four of the five relays in each module are usedto annunciate system logic. The remaining relay reflects theOK/NOTOK status of the associated protection path. The

Bently Nevada Monitor Configuration softwareprovides a graphical interface to configurerelay logic. The state of each relay isdetermined by the system inputs andconfigured system logic in conjunction with thecontrol state of the relay. Relay control statesdepend on the application, and may be set asnormally energized/de-energized andindependent one-out-of-one, (lool), voting orTMR two-out-of-three, (2oo3),voting. Each CPUmodule in the system has two, internallypowered, 4-20 mA recorder outputs controlledby the full-scale speed set by the user throughthe Monitor Configuration software.

Typical (and recommended) applications ofthe ADAPT ESD will use a triple modularredundant architecture. in this configuration,each processor module physically connects toan array of 32 input channels, 12 of which areconfigurable as discrete inputs or 4-20 mAanalog inputs, as well as two speed inputs. TheBently Nevada Monitor Configuration softwareallows you to configure large combinations oflogic blocks in order to manage the system triplogic. This logic dictates how the tripmechanisms for the system are driven. TheADAPT ESD system can drive 12 independent triprelays. of the 12 relays, six of these signals canoptionally be configured for two-out-of-three.(2oo3), voting. in the 2oo3 arrangement, the
