CTC AC93X-94X Class I Division 2 Sensors Owner’s Manual

CTC AC93X-94X Class I Division 2 Sensors

Introduction

This document contains information on the installation, operation, and maintenance of Class I Division 2 (Zone 2) Vibration Sensors with an Ex nA (North America and Europe) rating.

Type of Protection: Ex nA is based on the principle that any equipment in a hazardous area prohibits any arcs, sparks or hot surfaces that could cause ignition. It may be integral with the safe-area equipment or separate for greater flexibility.

Compliance with the Essential Health & Safety Requirements

Assured by compliance with EN60079-0: 2004, EN60079-15: 2005, EN61241-0: 2006, EN61241-1: 2005.

Installation

Installation Procedure

The Class I Division 2 (Zone 2) Control Drawing INS10035 (located in the Overview tab for the product listing at ctconline.com) shows the installation requirements for CTC Class I Division 2 (Zone 2) Sensors.

Notes:

• a. Approved Class I Div 2 (Zone 2) Cable required.
  b. Mechanical locking connector or integral connection

  • CTC’s Q2A/Q2R connectors has the cable shield drain connected to the connector backshell.

Operation

Standards

Each sensor that is approved for Class I Division 2 (Zone 2) must meet or exceed the requirements for standards recognized by the countries that would use the sensors.

Specific Conditions of Use

Specific ambient conditions of use include:

1. -40 °C to 80 °C for all LP series, AC93X and AC94X series sensors (T4).
2. -40 °C to 125 °C for all AC93X series sensors (T3).
3. -40 °C to 121 °C for all AC94X series sensors (T4).

Class I Division 2/Ex nA IIC when installed using an approved Division 2 (Zone 2) rated cable and connectors in accordance with the CEC or the NEC. European installation shall conform to IEC60079-14 or the applicable local installation code. Suitability of final installation is to be determined by the authority having local jurisdiction.
