1.07.004 LOGIX panel - Signal Conditioner (Phoenix Contact brand) - Gas Engine drive with Dip Switch Positions

This Policy is completed waiting on Field Service, Engineering, and Safety dept approval

Purpose

The purpose of this procedure is to establish the minimum requirements for setting up the Phoenix Contact brand Signal Conditioner on the Gas Engine drive LOGIX control panel.

Phoenix Contact part # MINI MCR-SL-I-U-4

Flogistix NetSuite part# 009-034-009

This procedure applies to all Gas Engine type LOGIX panels equipped with the Phoenix Contact brand Signal Conditioner (Not Red Lion type) that converts an incoming battery voltage to a readable voltage signal referred to as a Low Resolution Signal that the LOGIX PLC will accept. This procedure is to ensure the proper set up of the Phoenix Contact brand Signal Conditioner to ensure the proper output voltage for a Low Resolution Signal that the LOGIX panel will accept as laid out in this procedure.

Procedure

This procedure applies to all Gas Engine Drive units that are equipped with a LOGIX panel that has a Phoenix Contact brand Signal Conditioner for Battery Voltage that is currently in service in the Field, Test Loop, at a Repair Shop, or in Storage Yards. Flogistix Service Technicians will perform the task of the proper set position of the Dip Switches on the Phoenix Contact brand Signal Conditioner in the LOGIX panel as laid out in this procedure.

The LOGIX touchscreen displays battery voltage and the PLC will monitor high and low battery voltage. The PLC operates on a minimum of 20 VDC to a maximum of 28 VDC. The LOGIX PLC can only accept Analog & Digital siginals along with one (1) Low Resolution signal. The Low Resolution signal going into the PLC can only be a zero (0) to ten (10) volt DC signal. For the PLC to accept a incoming voltage greater than the ten (10) VDC of the Low Resolution input a Signal Conditioner must be used to convert the the signal to the acceptable Low Resolution voltage. For Gas Engine drive LOGIX panels the battery voltage on 12 VDC or 24 VDC must be ran through a Signal Conditioner to be converted to a 0 to 10 VDC signal that the PLC will accept.

Before any work is performed a JSA needs to be done according to Flogistix procedure along with any Customer requirements before any work is started.

When replacing a Phoenix Contact brand Signal Conditioner the Dip Switches on the Signal Conditioner need to be in the proper position for the incoming battery voltage and the proper output voltage referred to in this procedure as the Low Resolution Signal.

This procedure can also be used on existing LOGIX panels to verify the proper position of the Phoenix Contact Signal Conditioner Dip Switches for diagnostic of the LOGIX incoming battery voltage and the Low Resolution signal going to the PLC.

To properly set up the correct position of the Dip Switches use a small pointed tool or object to flip the switches either up or down to the On or Off position according the example below..

Responsibilities

Management - Management is responsible for implementing, supporting, and enforcing the requirements of this procedure to their respective locations/area.

EHSS - Responsible to assist in the implementation of this procedure and to review for effectiveness.

Employees, Contractors, Vendors, ETC. - Are responsible to follow the requirements outlined in this procedure and ask for assistance

Scope
