Precautions
!CAUTION
If this product should malfunction and cease to provide
correct output, property damage may occur to the
equipment or device that is connected to it. To prevent
this, provide additional safety measures by also
connecting the equipment or devices to a separate alarm
system that will warn operators of temperature rises.
Precautions for Correct Use
1.
The thermocouple output and power supply are not isolated.
Make sure that unwanted circuit paths are not formed with the
equipment or device that is connected to the product.
2.
To prevent inductive noise, wire the product separately from high-
voltage sources and power lines carrying large currents. Also
avoid parallel wiring or shared wiring paths with power lines.
3.
Do not allow the filter to become soiled. Use air blow or use a thin
cotton swab to clean the filter.
Precautions for Safe Use
1.
Use the ES1B only within the ranges specified by its
specifications and ratings.
2.
Be sure to correctly wire the input sensor leads to the proper
positive and negative terminals.
3.
Do not use the product in the following locations:
•
Locations subject to icing or condensation.
•
Locations subject to excessive shocks or vibration.
•
Locations subject to dust or corrosive gases.
•
Locations subject to extreme temperature changes or direct
sunlight.
•
Locations subject to water splashing or oil contact.
1. Installation
•
Select a place where the emissivity is high for measuring the target.
If necessary, use black spray or black tape.
•
Use the supplied locknuts to fix the ES1B securely in place. Tighten
to a torque of 0.5 N·m max.
•
When measuring a high-temperature object, use a shield or similar
protection to prevent the temperature of the ES1B from rising.
2. Connection
•
Connect to the green output lead wire (+), white output lead wire
(
-
), orange power supply lead wire (+), and shield power supply
wire (
-
).
•
To measure the temperature difference between two locations, use
two isolated power supplies.

3. Adjustment
•
The output impedance of the ES1B is 1 to 4 k
W
. Normally, current
leaking to the ES1B from the burnout detection circuit of the
temperature controller will offset the measured temperature in a
range extending from several degrees to several tens of degrees.
When using a controller equipped with an input shift function, use
the input shift function to compensate for this offset error in the
vicinity of the measuring temperature. For details on this
compensation, see Input Shift Method below and the user's manual
of the controller being used.
•
If the length of a lead wire must be extended, use a K thermocouple
compensating conductor for the output lead wires (+,
-
), and
standard copper wire for power supply leads (+,
-
).
•
Do not bend lead wires repeatedly.
4. Cleaning
•
Do not use paint thinner or the equivalent for cleaning. Use
standard grade alcohol.
