• The default alarm type is "2".
*1: Upper and lower limits can be set for parameters 1, 4 and 5 to provide for
different types of alarm. These are indicated by the letter "L" and "H".
*2: Refer to the tables above for details of input types and alarm types.
*3: Only the value set to the ins: Temperature Input Shift parameter is applied to the
entire temperature input range. When the process value is 200°C, the process value is
treated as 201.2°C after input shift if the input shift value is set to 1.2°C. The process
value is treated as 198.8°C after input shift if the input shift value is set to -1.2°C.
*4: Operation is stopped when moved to the initial setting level.
(control/alarm are both stopped.)
*5: The four numeric digits of the product code are displayed in the No. 2 display.
The setting cannot be changed and there is nothing that you need to set.
* The grayed-out setting items are not displayed for some models and some
settings of other setting items.

Warning Symbols
CAUTION
Minor injury due to electric shock may occasionally occur.
Do not touch the terminals while power is being supplied.
Electric shock, fire, or malfunction may occasionally occur. Do not allow metal objects, conductors,
cuttings from installation work, or moisture to enter the Digital Controller, the Setup Tool ports, or
between the pins on the connectors on the Setup Tool cable. Attach the cover to the front-panel
Setup Tool port whenever you are not using it to prevent foreign objects from entering the port.
Do not use the product where subject to flammable or explosive gas. Otherwise, minor injury from
explosion may occasionally occur.
Never disassemble, modify, or repair the product or touch any of the internal parts. Minor electric
shock, fire, or malfunction may occasionally occur.
CAUTION - Risk of Fire and Electric Shock
a) This product is UL listed as Open Type Process Control Equipment. It must be mounted in an enclosure that
does not allow fire to escape externally.
b) More than one disconnect switch may be required to de-energize the equipment before servicing.
c) Signal inputs are SELV, limited energy.
d) Caution: To reduce the risk of fire or electric shock, do not interconnect the outputs of different Class 2 circuits.
If the output relays are used past their life expectancy, contact fusing or burning may occasionally occur.
Always consider the application conditions and use the output relays within their rated load and
electrical life expectancy. The life expectancy of output relays varies considerably with the output load
and switching conditions.
Loose screws may occasionally result in fire. Tighten the terminal screws to the specified torque of 0.43
to 0.58 N•m.
Set the parameters of the product so that they are suitable for the system being controlled. If they are
not suitable, unexpected operation may occasionally result in property damage or accidents.
A malfunction in the Digital Controller may occasionally make control operations impossible or prevent
alarm outputs, resulting in property damage. To maintain safety in the event of malfunction of the Digital
Controller, take appropriate safety measures, such as installing a monitoring device on a separate line.

Precautions for Safe Use
Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse effects on the
performance and functions of the product. Not doing so may occasionally result in unexpected events.
Use the product within specifications.
(1) The product is designed for indoor use only. Do not use the product outdoors. Do not use or store the product
in any of the following locations.
•Places directly subject to heat radiated from heating equipment.
•Places subject to splashing liquid or oil atmosphere.
•Places subject to direct sunlight.
•Places subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas).
•Places subject to intense temperature change.
•Places subject to icing and condensation.
•Places subject to vibration and large shocks.
(2) Use/store within the rated temperature and humidity ranges. Provide forced-cooling if required.
(3) To allow heat to escape, do not block the area around the product. Do not block the ventilation holes on the product.
(4) Be sure to wire properly with correct polarity of terminals.
(5) Use the specified size of crimped terminals (M3, width 5.8 mm or less) for wiring. To connect bare wires to the
terminal block, use copper braided or solid wires with a gage of AWG24 to AWG18 (equal to cross- sectional
area of 0.205 to 0.8231 mm ). (The stripping length is 6 to 8 mm.) Up to two wires of same size and type, or
2
two crimped terminals can be inserted into a single terminal.
(6) Do not wire the terminals which are not used.
(7) Allow as much space as possible between the controller and devices that generate a powerful high- frequency
or surge. Separate the high-voltage or large-current power lines from other lines, and avoid parallel or
common wiring with the power lines when you are wiring to the terminals.
(8) Use this product within the rated load and power supply.
(9) Make sure that the rated voltage is attained within two seconds of turning ON the power using a switch or relay
contact. If the voltage is applied gradually, the power may not be reset or output malfunctions may occur.
(10) Make sure that the Digital Controller has 30 minutes or more to warm up after turning ON the power before
starting actual control operations to ensure the correct temperature display.
(11) A switch or circuit breaker should be provided close to this unit. The switch or circuit breaker should be within
easy reach of the operator, and must be marked as a disconnecting means for this unit.
(12) Wipe off any dirt from the Digital Controller with a soft dry cloth. Never use thinners, benzine, alcohol, or any
cleaners that contain these or other organic solvents. Deformation or discoloration may occur.
(13) Design system (control panel, etc) considering the 2 second of delay that the controller's output to be set after
power ON.
(14) The output will turn OFF when you move to the Initial Setting Level. Take this into consideration when
performing control.
(15) The number of non-volatile memory write operations is limited. Therefore, use RAM write mode when
frequently overwriting data during communications or other operations.
(16) When disassembling the Temperature Controller for disposal, use suitable tools.
(17) Do not connect cables to both the front-panel Setup Tool port and the top-panel Setup Tool port at the same
time. The Digital Controller may be damaged or may malfunction.
(18) Do not exceed the communications distance that is given in the specifications and use the specified
communications cable. Refer to the E5@C-T Digital Controllers User's Manual (Cat. No.H185) for the
communications distance and cable specifications.
(19) Do not turn the power supply to the Digital Controller ON or OFF while the USB-Serial Conversion Cable is
connected. The Digital Controller may malfunction.
(20) The terminals can reach temperatures of up to 75°C.

Error Display (troubleshooting)
When an error has occurred, the No.1 display shows the error code. Take necessary measure
according to the error code, referring the table below.
No.1 display Meaning Action
Check the setting of the Input Type parameter, check the input wiring,
Input error
s.err
(S. Err)
and check for broken or shorts in the temperature sensor.
*
After the check of Input error, turn the power OFF then back ON again. If
A/D converter
the display remains the same, the controller must be repaired. If the display
e333
(E333) error
is restored to normal, then a probable cause can be external noise affecting
the control system. Check for external noise.
*
Turn the power OFF then back ON again. If the display remains the same, the
e111
(E111) Memory error controller must be repaired. If the display is restored to normal, then a probable
cause can be external noise affecting the control system. Check for external noise.
If the input value exceeds the display limit (-1999 to 9999), though it is within the control range, [[[[ will be displayed
under -1999 and ]]]] above 9999. Under these conditions, control output and alarm output will operate normally. Refer
to the E5@C-T Digital Controllers User's Manual (Cat. No. H185) for the controllable ranges.
* Error shown only for "Process value / Set point". Not shown for other status.
