Acidic Operating Conditions
Refer to Chemical Compatibility on page 121. Contact your local OMRON representative for
more information.
Outer Arms
The outer arms are a composite assembly of carbon fiber and stainless steel. The interior
volume of the carbon fiber tube is sealed with an internal and external continuous epoxy bond.
Spring retainer pins are press-fit into the outer-arm ends with a slight interference to hold the
spring-retainer.
The outer arms may be cleaned either with wash-down in place on the robot, or removal and
tank cleaning.
Spring Assemblies
The outer arms are attached through the positive pressure of springs that are made of electro-
polished stainless steel. The springs attach to the arms via plastic retainers that fit over pins
on the arms. This open spring-assembly design allows inspection for contamination, as well
as wash-down.
Platforms
The iX4-650HS/800HS supports four types of platforms, depending on the amount of Theta
rotation and inertia needed. All four platform types are available in stainless steel for either the
iX4-650HS or iX4-800HS robot.
All platforms are designed to meet the basic criteria of wash-down compatibility and long life.
Please contact your local OMRON representative for more information.
6.5 Checking Safety Systems
Use the following steps to check all robot safety devices that may be present in the system.
These tests should be performed at least every six months.
IMPORTANT: Operating any of the following safety devices should disable
robot high power.
E-stop button on the Front Panel or connected to the XSYSTEM cable.
l
E-stop button and enabling switch on the pendant (if present).
l
Any other user-supplied safety devices that have been installed in the robot system.
l
IMPORTANT: The High Power indicator must be operational to satisfy safety
requirements. Refer to the following section.
High Power Indicator Check
The robot monitors current used by the High Power indicator. This is to ensure that a High
Power indicator device is connected and functioning properly to satisfy safety requirements.
If the robot does not detect a current between 10 mA to 500 mA when High Power is requested,
an error condition (-924) *Front panel HIGH POWER lamp failure* will be present and High
Power will not be enabled.
