1 General Safety Precautions
WARNING Do not attempt to disassemble, apply pressure, distort, subject to temperatures
of 100°C or more, or throw the E5ZE into fire. A lithium battery is built into the
E5ZE and any attempt to any of the above may result in fire, explosion, or
combustion.
WARNING Do not attempt to disassemble, modify, or repair the E5ZE. Any attempt to do so
may result in malfunction, fire, or electric shock.
Caution Do not use any terminal that is marked “Don’t use.”
2 Operating Environment Precautions
Caution Be sure to check polarity when connecting the terminals.
Caution Do not install power lines or high-tension lines alongside lines connected to the
E5ZE to prevent the E5ZE from being influenced by inductive noise. Install lines
connected to the E5ZE through an independent conduit or use a shielded cable
for the lines to protect them from inductive noise.
Caution Separate the E5ZE from devices generating a strong high-frequency, such as
high-frequency welding machines, or devices that generate surge.
Caution Do not operate the E5ZE in the following locations:
•Locations subject to exposure to water, oil, or chemicals.
•Locations subject to corrosive or flammable gases.
•Locations subject to temperatures or humidity outside the range specified in
the specifications.
•Locations subject to condensation.
•Locations subject to shock or vibration.
•Locations subject to severe changes in temperature.
•Locations subject to icing.
Caution Do not install the E5ZE in a location with obstructions preventing radiant heat
from escaping.
3 Application Precautions
WARNING Make sure that no metal particles or wire chips are accidentally left in the
product. Doing so may result in malfunction, fire, or electric shock.
WARNING Install a separate alarm to prevent the temperature from increasing excessively
if the E5ZE malfunctions. Insufficient safety precautions may cause serious
accidents if the temperature control malfunctions.

xiii
Caution Tighten the screws on the terminal block to the torque specified in the manual.
Loose screws may result in burning or malfunction.
Caution Do not connect loads to the E5ZE that exceed the specified ratings. Excessively
large loads may result in malfunction or burning.
Caution Always use the power supply voltage specified in the manual. An incorrect volt-
age may result in malfunction or burning.
Caution Confirm that no adverse effects will occur in the system before attempting to per-
form a hardware test. Insufficient confirmation may result in unexpected opera-
tions.
Caution Make sure that all the E5ZE set values are suitable for the controlled system.
Unsuitable set values may result in unexpected operations causing damage to
the product or accidents.

The components of the E5ZE contained within bold lines in the above diagram
are electrically isolated.
Note The covers of the CT INPUT, CONTROL, and ALARM connectors are con-
nected to the frame ground (FG).
For the E5ZE-8TC(Thermocouple Input Models), the thermocouple
inputs of the control points are insolated from each other.
1-3 Main Functions
The E5ZE is connected to platinum resistance thermometers or thermocouples,
depending on the model used. The type of temperature sensor is specified using
the INPUT selector on the front panel of the Unit. The input values can be ad-
justed using the input adjustment function.
The control outputs can be either voltage output or current output, depending on
the model. The control period and direct/reverse operation can be specified us-
ing the set values.
A maximum of 2 alarm outputs are possible. There are 12 alarm modes that can
be set for each alarm output according to set values. The outputs are compre-
hensive output for all control points.
The output values are limited by the following 2 limiters:
•Output limiter
•Output change rate limiter
If an output value is outside the upper or lower limit for the output, the output will
be limited to the preset upper or lower limit. The output change rate limiter limits
the rate at which output values change per unit time.
The ramp function is used to limit the control temperature (set point) from chang-
ing rapidly. If the set point changes quicker than the preset rate, the rate of tem-
perature change will be limited to the preset rate, and the temperature will gradu-
ally change until it reaches the new temperature. The ramp can be set by the
user.

PID and fuzzy constants can be set by executing auto-tuning (AT). If an offset
occurs during P or PD control, manual adjustment is possible using the manual
reset function. Temperature turbulence caused by external disturbances can be
suppressed and controlled using the fuzzy function.
Output short circuits caused by heater burnout or SSR failure can be detected.
Control can be switched between ON/OFF control and the normal 2-PID control
(with 2 degrees of freedom). Manual operation is also possible.
The memory banks store different sets of set values for the control points. There
are 8 memory banks for each control point. Memory banks allow the set values
for a control point to be changed as a group rather than resetting them individu-
ally. Use the external contact inputs or communications to designate the re-
quired memory bank.

Use appropriate Phillips screwdriver for the screws. Use of an inappropriate
screwdriver may damage the screws and cause insufficient tightening.
Mount the Units in an environment where anti-static electricity countermeasures
have been taken.
Store the removed screws carefully and use them again when required.
Model With Casing
1, 2, 3... 1. Remove the connector fixing screws (2 screws each for a connector) from
the Units (except for communication unit).
2. Remove the casing fixing screws (6 screws).
3. Remove the casing.
4. Mount the Units in the same manner as the model without casing.
5. Fix the connector to the case using the connector fixing screws with a torque
of 0.34 to 0.39 Nm.
6. Replace the casing in its original position using six casing fixing screws.

2-3 Setting Selectors and Switch
Observe the following precautions when operating the selectors and switch.
•Always make sure the power is OFF before changing the selectors and switch.
•Use a small flat-blade screwdriver to change the selector and switch settings,
and be sure that the selectors are correctly positioned.
2-3-1 UNIT Selector
UNIT INPUT
When serial communications are being used, the UNIT selector must be set so
that the host device can recognize the E5ZE unit number.
When more than one E5ZE Multipoint Temperature Controller is being used with
RS-422 or RS-485 communications, set a different unit number for each E5ZE.
•The selector settings 0 to F correspond to unit numbers 00 to 0F. The factory
setting of 0 corresponds to unit number 00.
2-3-2 INPUT Selector
UNIT INPUT
Set the INPUT selector according to the type of temperature sensor connected
to the E5ZE. The selector positions and corresponding temperature sensors are
as follows:
Selector
setting 0 1 2 3 4 5 6 7 8 9 A B C D E F
Thermocouple K J R S T E B N L U W PLII Not used.
Platinum

Pt JPt Not used.
•The factory setting is 0.
•The platinum resistance thermometer settings “Pt”and “JPt”indicate Pt100
and JPt100 respectively.

Baud rate (serial communications)
Set the baud rate using pins 1 and 2 to the baud rate of the host device con-
nected to the EZ5E.
Baud rate 19,200 bps 9,600 bps 4,800 bps 2,400 bps
Pin 1
Pin 2
The factory setting is 9,600 bps (pin 1 ON, pin 2 OFF).
Pin 3 is used to set the memory bank designation method.
Memory bank

Pin 3
The factory setting is for communications (pin 3 OFF).
When contact inputs are used to switch memory banks, the specified memory
bank will be used for all control points.
Pin 4 is used to specify when an E5ZD-SDL Setting Display Unit is connected.
E5ZD-SDL connection Not connected Connected
Pin 4
The factory setting is for no connection (pin 4 OFF). Set pin 4 to ON when an
E5ZD-SDL Setting Display Unit is to be connected to the E5ZE.
