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.
