h When the difference between setting value and processing temperature is large when
the temperature falls.
Fluctuation is given at the temperature 20°C (°F) or higher than the setting value.
8. Mounting to the control panel
8.1 Site selection
Mount the controller in a place with:
(1) A minimum of dust, and an absence of corrosive gases.
(2) No mechanical vibrations or shocks.
(3) No exposure to direct sunlight, an ambient temperature of 0 to 50°C (32 to122°F)
that does not change suddenly.
(4) An ambient non-condensing humidity of 35 to 85%RH or less.
(5) The controller away from large capacity electromagnetic switches or cables
through which large current is flowing.
(6) No water, oil or chemicals or where the vapors of these substances can
come into direct contact with the unit.
