Operating States & Output Modes
Operating States
The following operating states exist for the OS32C system.
1. OSSD ON State
The two safety outputs are in the ON state, and the machine run (green) indicator is lit. The protected machine
is allowed to operate. The state/diagnostic display indicates a state of monitoring zone set selection and a
response time.
2. OSSD OFF State
An object exists in a safety zone and it is being detected. The two safety outputs are in the OFF state, and the
machine stop (red) indicator and the intrusion indicators in the affected region(s) are lit. The protected
machine is not allowed to operate. The status/diagnostic display shows "- -".
3. Interlock State
This state waits for a start input (See p.17 for details.). The two safety outputs are in the OFF state, the red
STOP indicator and yellow interlock indicator are lit. The protected machine is not allowed to operate. The
status/diagnostic display shows "01".
4. Lockout State
A failure is being detected and the guarded machine is being stopped. The two safety outputs are in the OFF
state, the machine stop (red) indicator is lit and yellow interlock indicator is flashing. The protected machine is
not allowed to operate. The status/diagnostic display shows the error code that caused the lockout. The
OS32C system will remain in the lockout state until the problem is corrected and a start input is applied or
power on the unit is cycled.
