Section 1 Introduction

1-5-3 Microprocessor Transmitter with or without Inductive Alarms

This combined system provides both the sophistication of the

microprocessor along with the simplicity of one or two switch inductive

alarms. Specifications for the transmitter are as stated previously and

specifications for the front adjustable alarms are as described in the

section Inductive Alarm Switches.

Wiring diagrams

Refer to Figures 1-4, 1-6 and 1-8

For Division 1 explosion proof installations, the optional explosion proof

enclosure must be used. This enclosure does not use the auxiliary

terminal box, as shown on some of the installation diagrams. All

connections are made directly within the housing.

For Division 2 non-incendive installations, either the standard enclosure or

the explosion proof enclosure may be used.

For both Division 1 explosion proof and Division 2 non-incendive

installations, the barriers shown in the installation drawings are optional.

Wiring must be done in accordance with the applicable electrical codes,

i.e., NEC Chapter 5 and CEC Section 18, Canadian Electrical Code and

any local codes.

Transmitter accessories

General purpose and intrinsically safe HART compatible power supplies

are available in 120V and 240V.
