Omron OS32C Series User Manual page 7

The machine requirements
The guarded machine must be able to stop anywhere in its cycle. Do not use an OS32C on a press
with a full-revolution clutch.
The guarded machine must have a consistent stopping time and adequate control mechanisms.
All safety-related machine control elements must be designed so that an alarm in the control logic
or failure of the control circuit does not lead to a failure to danger.
Do not use the auxiliary output or warning output for safety applications. A human body may not be
detected even if a failure of OS32C occurrs, resulting in serious injuries.
Installation
The main unit must be securely mounted and its cable connectors must be tightly attached.
A start switch to release interlock must be installed where an operator can observe the monitored/
guarded zone as a whole and cannot operate the switch within the hazardous zone.
A protective mechanism must be installed to prevent a hazardous condition in the event of a
subsequent machine component failure. The OS32C does not protect against ejected flying
material.
Severe smoke and particulate matter may degrade the efficiency of an OS32C, causing it to
unexpectedly enter a Machine Stop state.
Use of mirrors or mirror-like objects in the protection plane must be avoided, as they can hide part
of the area to be monitored/guarded.
Additional guarding may be required to prohibit access to dangerous areas not covered by the
OS32C system.
Perform the test procedure in this document at installation, after maintenance, adjustment, repair
or modification to the machine controls, tooling or the OS32C system. See page 144.
Perform only the test and repair procedures outlined in this manual.
Additional measurement error resulting from reflective backgrounds may need to be added to the
measurement error of the OS32C.
