• 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 specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. To connect bare wires to the 

terminal block, use copper braided or solid wires with a gage of AWG24 to AWG14 (equal to cross- sectional 
area of 0.205 to 2.081 mm

2

). (The stripping length is 5 to 6 mm.) Up to two wires of same size and type, or 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) Always turn OFF the power supply before pulling out the interior of the product, and never touch nor apply 

shock to the terminals or electronic components. When inserting the interior of the product, do not allow the 
electronic components to touch the case. 

(13) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol. 
(14) Design system (control panel, etc) considering the 2 second of delay that the controller’s output to be set after 

power ON.

(15) The output may turn OFF when shifting to certain levels. Take this into consideration when performing control.
(16) The number of non-volatile memory write operations is limited. Therefore, use RAM write mode when 
 

  frequently overwriting data during communications or other operations.

(17) The product's Setup Tool port and Infrared communication port are internally connected in models. Stop 

transmission from Infrared communication port before using the Setup Tool port.

(18)   Read the information provided in the catalog and manual and be sure you understand it before attaching a Control 

Output Unit. 

(19)  Always use suitable tools to dismantle the product for disposal.

In this level, the SPs and times 
are input for the programs. 

*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". 

  • The default alarm type is "2"

*2: Error shown only for "Process value / Set point". Not shown for other status. 

When an error has occurred, the No.1 display shows the error code. Take 
necessary measure according to the error code, referring the table bellow.

If the input value exceeds the display limit ( -19999 to 32400), though it is within the control 
range, 

[[[[

will be displayed under  -19999 and        

]]]]

 above 32400. Under these conditions, 

control output and alarm output will operate normally.
For information on the controllable range, refer to the 

E5CN-HT/E5AN-HT/E5EN-HT Digital Controllers 

User's Manual 

(Cat. No. H169).

Turn the power OFF then back ON again. If the 
display remains the same, the 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.

After the correction of A/D converter error, turn the 
power OFF then back ON again. If the display 
remains the same, the 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.
