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.
3Application Precautions
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.
xii
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.
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 operations.
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.

Ramp
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 adjusted 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 using 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 comprehensive 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 changing rapidly. If the set point changes quicker than the preset rate, the rate of temperature change will be limited to the preset rate, and the temperature will gradually change until it reaches the new temperature. The ramp can be set by the
user.

Main Functions
Section 1-3
Control Adjustment
Heater Burnout and SSR
Failure Detection
Control Method Selection
Memory Banks
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 individually. Use the external contact inputs or communications to designate the required memory bank.

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
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.

Operation Mode Change
The factory setting is for degrees Celsius (pin 6 OFF).
When the temperature unit is changed, the temperature data does not automati-
cally change, so make sure to reset the temperature using the following procedure.
2. Recalculate the data according to the following conversion formula and reset the control data within the setting range.
(value in F) = 1.8 x (value in C) + 32
3. Store the settings in memory.

Mount the Unit using the methods shown here. The Unit will not operate properly
if other methods are used to mount the Unit.
• Use the following mounting screws. Make sure the length of the screws is appropriate for the mounting panel used.
E5ZE-8B: 4 x M4 screws
• Use spring and flat washers and tighten to a torque of 0.43 to 0.58 N m {4.4 to
5.9 kgf cm}.
• Do not mount the terminal block with the connectors facing upwards. Doing so
may cause measurement errors.

2-5 Power Supply and Input Wiring
2-5-1 Terminal Block
The input terminal block has been designed with a removable terminal-screw
panel. When connecting the power supply or temperature sensor, the terminalscrew panel can be conveniently removed before wiring.
• To remove the terminal-screw panel, loosen the two screws alternately indicated by A in the above diagram.
• To mount the terminal-screw panel, insert it into the terminal block and secure
the two screws (A) alternately.
• If the terminal block has been removed from the E5ZE Thermocouple Input
Model, when reconnecting make sure that the E5ZE’s lot number and serial
number are the same as those of the terminal block. Accuracy cannot be guaranteed for a Unit that has been connected to a terminal block with a different lot
number and serial number.
2-5SectionPower Supply and Input Wiring
2-5-2 Wiring
• Always turn OFF the power supply before performing any wiring.
• Be sure to check polarity when connecting the power supply and temperature
sensor.
• Wire the power supply cables separately from the temperature sensor cables
to prevent noise interference.
• Use either crimp terminals or solder the wire ends when wiring terminals.
• Tighten the terminal screws.
• Wire the power lines close to the terminal block to prevent external force being
exerted on the power lines from torsion or weight.
• Do not use the terminals that are marked “Don’t use.”
• Do not bend the crimp terminals after they have been connected and the
screws have been tightened.
