Abbreviations
The following table lists the main abbreviations used in parameters, diagrams, and in the text itself.
Note Scaled data is expressed in °C, m, g, and other engineering units. EU is used
as the minimum unit for engineering units For example, the smallest unit of
50.02 (m) is 0.01 (m) and 0.01 is thus one EU.
Parameter Notation
The following table shows the alphabet notation used for parameter abbreviations and settings dis-
played on the E5ZN-SDL Setting Display Unit.

About this Manual:
This manual describes how to use the E5ZN and includes the sections described below.
Before using your E5ZN, thoroughly read and understand this manual in order to ensure correct use.
Also, store this manual in a safe place so that it can be accessed whenever necessary.
The E5ZN Temperature Controller allows the user to perform the following:
• Control temperature for two channels with one Temperature Controller. The Temperature Controller
can be expanded to control up to 32 channels.
• Use an E5ZN-SDL Setting Display Unit to set the Temperature Controller.
• Input non-contact temperature sensors, analog voltages, thermocouples, or platinum-resistance ther-
mometers.
• Select heating/cooling control in addition to standard control.
• Select autotuning as the tuning function.
• Use multi-SP and a RUN/STOP function with event inputs.
• Use a HBA (heater burnout alarm).
• Use communications.
The E5ZN conforms to UL/CSA/ICE safety standards and EMC standards.
Precautions provides general precautions for using the E5ZN.
Section 1 describes E5ZN features, part names, and main functions.
Section 2 describes mounting, wiring, and other preparatory work that must be done before the E5ZN
can be used.
Section 3 describes the basic settings required by the E5ZN.
Section 4 describes scaling, SP ramp, and other functions to enable maximum use of the E5ZN func-
tions.
Section 5 describes performing communications for the E5ZN.
Section 6 describes how to operate the E5ZN-SDL Setting Display Unit.
Section 7 describes the parameters used to control E5ZN operation.
Section 8 classifies problems by situation and describes the methods for checking any possible mal-
functions.
!WARNING Failure to read and understand the information provided in this manual may result in per-
sonal injury or death, damage to the Temperature Controller, 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.
