  • Page 113: Introduction

    Introduction Section 6-1 Introduction 6-1-1 Outline The E5ZN-SDL Setting Display Unit is used to set and display parameters for E5ZN Temperature Controllers. Using the E5ZN-SDL simplifies the initial settings and maintenance of the E5ZN. 6-1-2 Preparation The E5ZN-SDL uses serial communications to display the settings for the E5ZN Temperature Controller.

  • Page 114: System Configuration

    • Keep the total cable length to 500m maximum. • Attach a terminator to both ends of the transmission path. Note Communications with the E5ZN-SDL will be cut if the E5ZN-2 connection to the E5ZN- SCT24S-500 is broken The E5ZN Temperature Controller and the E5ZN-SDL are connected by serial communications.
