About this Manual:
This manual describes the operation of the E5ZD Multipoint Temperature Controller and includes the sec-
tions described below. The Current Transformer (E54-CT1 or E54-CT3) is not provided with the E5ZD
Multipoint Temperature Controller. Purchase current transformers as required for heater burnout detec-
tion. The Terminal Block, I/O Block Unit, and cable are not provided with the E5ZD-8HjjM-E. For de-
tailed operating commands of the accessories, refer to their operation manuals.
Please read this manual completely and be sure you understand the information provided before attempt-
ing to operate the E5ZD Multipoint Temperature Controller.
Section 1 introduces the E5ZD, describing the various models available and the basic type of system
application.
Section 2 provides the steps necessary to prepare for operation, including switch settings and wiring
specifications, and also describes the components of the E5ZD.
Section 3 describes the basic operations used to control the E5ZD, including the communications
formats necessary for communication from a host computer or PC.
Section 4 describes each of the commands used to control E5ZD operation and the responses re-
turned by the E5ZD to indicate execution status.
Section 5 shows how to compute the time required to write data and have that data become effective
in operation, and the time required to read data.
Section 6 describes basic troubleshooting via lists of the possible causes and solutions to some
common operational problems.
Appendix A provides the technical specifications of the E5ZD and the optional Current Transformers
which are used for HB and HS alarms.
Appendix B provides lists of commands by function, showing the header codes, factory-set default
values, and setting limits.
Appendix C provides a short list of the end codes returned with E5ZD responses to indicate execu-
tion status.
Appendix D provides a table of the error code used in E5ZD communications.
Appendix E provides a table of the ASCII code used in E5ZD communications.
WARNING Failure to read and understand the information provided in this manual may result in
personal injury or death, damage to the product, or product failure. Please read each
section in its entirety and be sure you understand the information provided in the section
and related sections before attempting any of the procedures or operations given.
