■Setting Level Configuration and Panel Key Operations
Parameters are split into groups, which are referred to as levels. Each of the set values (set items) in these levels are referred to as parameters.
E5EZ-PRR parameters are categorized into the following 7 levels:
Note1:When returning from the initial setting lever to the operation level, the
operation level's initial value will be displayed.
2:When returning from the protect level to the operation level, the
operation level's initial value will be displayed.
∗: Set the initial/ communications protection parameter in protect level to 0, in order to activate the advanced function setting level.
❍: Indicates items that can be set. In these cases, the initial setting level, communications setting level, and advanced function setting level
can only be used when controls are stopped. Please take note of the fact that when any one of these three levels is selected, the controller's
output will be stopped.

■Descriptions of Each Level
• Protect Level •In order to switch to this level, it is necessary to press the and
Mkeys simultaneously for at least 3 seconds. This level is used to
prevent unnecessary or accidental revisions to the parameters.
The protected level is not displayed, so that no changes can be
made to parameters within this level.
• Operation Level •Once a power supply is connected, this level is displayed. It is
possible to switch from this level to protect level, initial setting lev-
el, and adjustment level.
•During regular operations, this level is selected. It is possible to
view process value and MV during operations, as well as viewing
and revising set values, alarm values, and upper and lower limits.
• Adjustment Level •In order to switch to this level, press the key for less than 1
second.
•Input in this level is used in controlling set values and shifted val-
ues. This level contains parameters used in setting up AT (auto-
tuning), communications writing enabling/ disabling, hysteresis,
multi-SP, input shift, and PID constants. It is possible to switch
from this level to the peak parameters in the initial setting level,
protect level, or operation level.
• Manual Control Level •Pressing the Akey for at least 1 second in operations/ adjust-
ment level will place you in manual mode and bring you to man-
ual control level. During manual operations, nothing besides
process value/ set value/ percentage of valve opening (manual
MV) can be displayed. In manual control, with process value/ set
value/ percentage of valve opening (manual MV) displayed,
pressing the Akey for at least 1 second will move you into auto-
matic mode and switch you to the operation level, displaying op-
eration level's initial data. In this mode, it is possible to perform
MV manual operations.
• Initial Setting Level •To switch to this level, it is necessary to press the key in op-
eration level or adjustment level for at least 3 seconds. One sec-
ond later, the PV display will flash. This level is used for
designating input types, selecting control methods and control
times, as well as setting direct/ reverse operations and alarm
types. From this level, it is possible to switch to the advanced
function setting level or communications setting level. Press the
key for at least 1 second to return to operation level. Press the
key for less than 1 second to switch to the communications

• Advanced Function Setting Level •In order to activate the advanced function setting level, set protect
level's initial setting/ communications protection to 0, and then in-
put the password (-169) in the input initial setting level.
•It is possible to switch from this level to the initial setting level.
•This level is used to set the display mode, event input assign-
ment, standby sequence, alarm hysteresis, and alarm delay.
• Communications Setting Level •To switch to this level, press the key in the initial setting level
for less than 1 second. When using the communications function,
the conditions of communication are to be set in this level. Com-
munications with a personal computer (host computer) allows set
values to be read and written, and manipulated variables to be
monitored.

■Setting the Type of Input
Types of input include thermocouple, platinum resistance thermometer, infrared temperature sensor,
and analog inputs. Please set your input type in accordance with the sensor to be used. Product spec-
ifications also include multi input types, such as thermocouples/ plastic resistance thermometers, and
analog input types, resulting in differences between set values. Please confirm the model that you are
using.

■Operation/ Adjustment Protection
The relationship between the set values and the range of protection is as shown below.
• When the set value is 0, there is no protective function.
• The initial value is 0.
■Initial Setting/ Communications Protection
This protect level restricts movement to the initial setting, communications setting, and
advanced function setting levels.
• Default setting: 1.
■Setting Change Protection
Places restrictions on changes to settings with keys.
off:Able to use unit keys to change settings.
on: Unable to use unit keys to change settings, but this level can be changed.
■Automatic/ Manual Key Protection
• Initial value is "off".
■Setting Communications Parameters
Configures the E5EZ-PRR's communications specifications, so that its communications
with the host computer can be configured properly. In a layout where one point communi-
cates with multiple points, in addition to all of the communication unit numbers, all other
settings should match. Each unit must have a single communication unit number set for it.

■Trouble shooting When an error occurs, the main display alternately shows an error signal and
the current item for display.
This section explains how to inspect an error signal, as well as corresponding
rectification measures.
• Meaning The figure inputted has exceeded the designated input range (the designated
range is between -1999 (-199.9) to 9999 (999.9)).
• Rectification Measures Check to make sure that the input line has not been connected incorrectly,
unplugged, a short-circuit, or is incompatible with this input type.
If there are no problems with the line type or the connection, power off and then
restart the unit. If the display remains unchanged, it will be necessary to change
the E5EZ-PRR. If the display is recovered, the root of the problem may have
been that noise from the energy flow was affecting the control system. Check for
any such noise.
• Operations with Errors The control output will be determined according to the designated value for
error MV.
The alarm output function will be the same as it is when the upper limit is
crossed.
After setting I/O error (advanced function setting level) on, alarm 1's output will
be activated in cases of error.
In process value or process value/ set value/ valve open percentage display
mode, error information will be displayed.
• Meaning Even though this is not really an error, when the range of control exceeds the
range of display (-1999 (-199.9) to 9999 (999.9)), and the process value is
beyond the range of display, this signal will appear.
•Will display [[[[ when the figure is less than -1999 (-199.9).
•Will display ]]]] when the figure is more than 9999 (999.9).
• Operations with Errors Control will continue and operations will remain normal. In process value or pro-
cess value/ set value/ valve open percentage display mode, error information will
be displayed.

Digital Position-Proportional Controllers E5EZ-PRR 47
• Meaning
• Rectification Measures
• Operations with Errors
There has been an error in the internal memory.
Power off and then restart the unit. If the display remains unchanged, it will be
necessary to change the E5EZ-PRR. If the display is recovered, the root of the
problem may have been that noise from the energy flow was affecting the control
system. Check for any such noise.
Control output and alarm output will be shut off.
• Meaning
• Rectification Measures
• Operations with Errors
Errors appear in potentiometer input. Valve opening has exceeded its regular
range of -10% to 110%.
Check to see if there have been any wiring errors, burnouts, or short-circuits in
the potentiometer.
If there are no problems with the wiring, you can restart the power supply. If the
display remains unchanged, it will be necessary to change the E5EZ-PRR.
If the display, the root of the problem may have been interference, which should
be avoided in the future.
The control output will be determined according to the designated value for error
MV.
Alarm output will operate as normal.
• Meaning
• Rectification Measures
• Operations with Errors
Electro-mechanical calibration was not properly completed.
After confirming the potentiometer and the wiring of the motor driving valve, per-
form electro-mechanical calibration again.
Control output and alarm output are OFF.

Ceramic Furnace Position Proportional Control
Reading the extent of the valve's opening with a potentiometer, and using open and close tuning control is referred to as position proportional con-
trol or on/ off servo control.
■Examples of Application
When using position proportional methods to control gas combustion furnace valves, position propor-
tional control should be applied. See the following figure for measurement devices:
The SP ramp function allows limits to be placed on temperature changes
which control the temperature within a specific range. This is useful for
ceramic furnace, in which severe temperature changes may cause dam-
age or corruption.
