Operating Environment - Yamaha RCX142 User Manual

3. Operating environment

Operating temperature 1
The ambient temperature should be maintained within a range of 0 to 40°C during
operation. This is the range in which continuous operation of the robot controller is
guaranteed according to the initial specifications. If the robot controller is installed in a
narrow space, then heat generated from the controller itself and from peripheral equipment
may drive the temperature above the allowable operating temperature range. This may
result in thermal runaway or malfunctions and may lower component performance along
with shortening their useful service life. So be sure to install the controller in locations
with a vent having a natural air flow. If this proves insufficient, provide forced air-cooling.
Storage temperature
The controller should be stored in a location at an ambient temperature between -10 and
+65°C when not being used. If the robot controller is stored in a location at high
temperatures for extended periods, deterioration of the electronic components may occur
and the memory backup time may decrease.
Operating humidity
The ambient humidity of the robot controller should be 35% to 85% RH (no condensation)
in order to guarantee continuous operation within the initial specifications. Installing the
robot controller inside an air-conditioned or cooled housing is recommended when the
ambient humidity is higher than 85% or when condensation occurs.
Storage humidity
The controller should be stored in a location at an ambient humidity below 95% RH (no
condensation) when not being used. If the robot controller is stored in a location at high
humidity for an extended period of time, rust may form on the electronic components.
Vibration and shock
Do not apply excessive shocks to the robot controller. Install the robot controller in a
location that is not subject to vibrations.
Atmosphere (gas, etc.)
Do not install the robot controller in locations where conductive dust particles, hydrogen
sulfide gas or sulfurous acid gas are present. Such an atmosphere may cause the components
to erode or poor installation. If such dust particles or gases are generated at the current
location, then installing the robot controller in an air-conditioned or cooled housing is
recommended.
Installation location
Always install the robot controller indoors, at a height of less than 1000 meters above sea
level.
This robot controller is neither dust-proof nor water-proof. Do not install it in locations
exposed to oil mist, cutting fluids or cleaning agents.
