1 Introduction

This manual describes the installation and the basic operation of the OMD200 and OMD300 automatic
control units. The instructive part is followed by a section on available accessories.

Caution:

provides important information or warns about a situation that may have a detri-

mental effect on equipment.

General warning:

warns about a situation where something other than electrical

equipment may cause physical injury to a person or damage to equipment.

Hazardous voltage:

warns about a situation where a hazardous voltage may cause

physical injury to a person or damage to equipment.

Information:

provides important information about the equipment.
