Introduction

Scope of Manual

This instruction manual includes installation and maintenance information for the Fisher LCP100 local control panel

(figure 1). This device is used with Fisher FIELDVUEt instruments in Safety Instrumented Systems (SIS). Refer to the

DVC6200 SIS Digital Valve Controllers for Safety Instrumented System (SIS) Solutions instruction manual

(D103557X012) or the DVC6000 SIS Digital Valve Controllers for Safety Instrumented System (SIS) Solutions

instruction manual (D103230X012) for additional information.

Unless otherwise noted, the information in this instruction manual applies to both DVC6200 SIS and DVC6000 SIS

digital valve controllers. For simplicity, the DVC6200 SIS model name will be used throughout.

Do not install, operate, or maintain an LCP100 local control panel without being fully trained and qualified in valve,

actuator, and accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is

important to carefully read, understand, and follow all of the contents of this manual, including all safety cautions and

warnings. If you have any questions about these instructions, contact your Emerson Process Management sales office

Instruction Manual LCP100 Local Control Panel D103272X012 November 2013 The LCP100 can be connected to a DVC6200 SIS that is part of an intrinsically safe system provided that you follow the instructions for the LCP100 Ex ic installation, as shown in figures 4 and 7. The overall intrinsically safe system would be rated as an Ex ic system. For all other approvals use zone 1 approved wiring practices.

Instruction Manual D103272X012 LCP100 Local Control Panel November 2013 Special Conditions for Safe Use 1. For Ex ic installations, it is not permitted to connect separate supplies to the LOOP+/LOOP and AUX+/LOOP terminals. 2. If the equipment is installed in a zone 2, the installer shall take suitable steps to indicate whether the equipment is installed as Ex e mb [ib] or Ex ic. Mounting Refer to figure 8 for dimensional information.

Instruction Manual LCP100 Local Control Panel D103272X012 November 2013 When connections are complete move the DIP switch to the appropriate power setting. If external 24 VDC is used to power the LCP100, make sure the switch is on the side that says “24VDC”. If loop power is used, slide the switch to the side that says “LOOP”. Note Factory default for the DIP switch power selector is 24VDC.

LCP100 Local Control Panel Instruction Manual November 2013 D103272X012 Emergency Demand through the Logic Solver 1. Reduce the current to the DVC6200 SIS to 4 mA (for de‐energize to trip operation). Note For a loop powered installation, a minimum current of 8 mA is required at the trip state / “Safety Demand” for proper functioning of the pushbuttons and lights. 2. Observe that the valve moves to its fail safe state. 3. Observe that the red light comes on solid and the yellow light stays off. 4.

The following parameters will be automatically set under Travel Alerts: d Hi Hi / Lo Lo Enable - Yes d Lo Lo Point (%) - 1 d Hi Hi Point (%) - 99 d Deadband (%) - 0.5 d DVC Power Up - Manual Reset D Continue to set up the digital valve controller according the normal set up procedure. D Remember to place the instrument back in service before disconnecting.

Instruction Manual LCP100 Local Control Panel D103272X012 November 2013 Note The primary safety function should be implemented by controlling the current (in point‐to‐point mode) or voltage (in multi‐drop mode) from the logic solver. The red button is not intended to perform the primary safety function for the process. Maintenance WARNING Electrostatic charge hazard. Do not rub or clean the LCP100 with solvents if a flammable vapor is present. To do so could result in an explosion.
