1 INTRODUCTION

1.1 Scope and definitions

This manual provides installation, operation and maintenance instructions for the Edwards IS16K Vacuum Interlock
Switch. Read this manual before attempting to install and operate the IS16K.

This manual contains essential safety information which supplements the safety features of the IS16K. Safety
procedures are highlighted as WARNING and CAUTION instructions. You must obey these instructions. The use of
WARNINGS and CAUTIONS is defined below.

CAUTION

Cautions are given where failure to observe the instruction could result in damage to the equipment, associated
equipment and process.

1.2 General description

The Edwards IS16K Vacuum Interlock Switch is designed for applications where the electrical circuits within the
vacuum chamber must be de-energised when the vacuum system is let up to atmosphere.

Typical applications would be the in terlocking of H.T. and R.F. power supplies on va cuum coating systems. The
interlocking switch consists o f a positive break microswitch operated by a snap action diaphram to ensure rapid
separation of the microswitch cont acts.

The diaphram is enclosed within the vacuum switch housing which is surrounded by atmospheric pressure and is
coupled to the vacuum system by a NW16 flange. The absolute switch point pressure will therefore vary by the same
amount as the atmospheric pressure.

The set-point is non-adjustable and cannot be tampered with.

WARNING

Warnings are given where failure to observe the instruction could result in injury or death to
people.
