Exemption from Responsibility
Make sure that all of the precautions are strictly adhered to. Yokogawa Electric Corporation assumes no liability
for any damage resulting from use of the instrument in contradiction to the precautions.
Also, Yokogawa Electric Corporation assumes no liability to any party for any loss or damage, direct or indirect,
caused by the use or any unpredictable defect of the instrument.
CAUTION
To prevent electric shock, the source of power to the controller must be turned off when mounting the controller
on to a panel.
NOTE
To install the controller, select a location where:
1. No-one may accidentally touch the terminals;
6. There are no resulting magnetic disturbances;
2. Mechanical vibrations are minimal;
7. The terminal board (reference junction compen-
3. Corrosive gas is minimal;
sation element, etc.) is protected from wind;
4. The temperature can be maintained at about 23
°
C with
8. There is no splashing of water; and
minimal fluctuation;
9. There are no flammable materials.
5. There is no direct heat radiation;
Never place the controller directly on flammable items.
If the controller has to be installed close to flammable items or equipment, be
sure to enclose the controller in shielding panels positioned at least 150mm
away from each side. These panels should be made of either 1.43mm thick
metal-plated steel plates or 1.6mm thick uncoated steel plates.
●
Mount the controller at an angle within 30
°
from horizontal with
the screen facing upward. Do not mount it facing downward.

• The left (upper) lamp is lit in orange during control output of standard type.
• In heating/cooling control, the left (upper) lamp lights up in orange when the heating-side output
is active; while the right (lower) lamp lights up in green when the cooling-side output is active.

• Pressing the key for 3 seconds or longer in the operating display retrieves the
operating parameter setting display.
• Pressing the key for 3 seconds or longer in either an operating or setup parameter
