Product Description

GENERAL INFORMATION

ZLS series limit switches are specifically designed for worldwide applications and is supported by Honeywell global

resources for sales and after sales service.

ZLS series limit switches are designed to the latest IEC standard are available and include a wide range of EN50041 and EN50047 type switches. Miniature EN50047 limit

switches are available in metal and double insulated enclosures and a metal enclosed 3-cable entry version (EN50047 mounting compatible) is also offered.

Standard ZLS switch circuit variations include 2 and 3-circuit versions with forceddisconnect mechanism. ZLS includes features to make quick installation easier and safer. Customers will benefit from Honeywell's vast experience in serving world industries over many years.

Most ZLS versions are interchangeable with almost all other makes of EN50041/47 switches.

STANDARDS

IEC 947-1 explains the general rules relating to Low-voltage switchgear and controlgear. The purpose of this standard is to harmonize as much as possible the product performance and test requirements for equipment where the rated voltage does not exceed 1,000 VAC or 1,500 VDC.

IEC 947-5-1 is part 5 of the general rules which relates to Controlcircuit devices and switching elements. Also within this part there is a section which considers Special Requirements. For Control Switches With Positive Opening Operation. Any control switch which has this positive opening operation and conforms to these special requirements will be marked on the outside of the product with this symbol:

The Contact Element Form defines the configuration of the contacts and the number of contacts within the switch. e.g.
   Form Za - both contact elements have the same polarity.

   Form Zb - the two contact elements are electrically separated.

The Utilization Category defines the type of current carried (AC) Alternating current,(DC) Direct current and the typical application in which the switch is used e.g.

   AC15 - Control of Electromagnetic Loads (less than 72VA)

   DC13 - Control of electromagnets.

The contact rating Designation relates to the utilization categories and defines the conventional thermal current lth (A), rated operational current le (A) at rated operational voltages Ue and the VA rating e.g.

   A600 - The ''A'' denotes the maximum VA rating (AC) and the ''600'' denotes the           maximum rated (AC) voltage.

   Q300 - The ''Q'' denotes the maximum VA rating (DC) and the ''300'' denotes the     maximum rated (DC) voltage.

These IEC standards have been adopted by CENELEC (The European Commitee for Electrotechnical Standardization) and have been identified by replacing IEC with EN 60 e.g.

   IEC 947-5-1 then becomes EN 60947-5-1.

CENELEC has defined the dimensions and characteristics of two types of limit switch in the standards EN 50041 and EN 50047. These standards relate to Low voltage switchgear and controlgear for industrial use and define the enclosure dimensions, the operating point for various head actuators, the earth terminal requirement, the terminal marking and the minimum degree of IP protection.
