Testing Alarm Conditions
Testing the IOC Operating Modes
Warm-up Mode
The IOC enters and remains in the Warm-up mode for approximately 30 minutes
after you apply power to the shelf, or when you install the IOC into the shelf. The
following actions occur when an IOC enters the Warm-up mode:
The Power LED on the IOC flashes green
An event is generated and stored in the event log
To verify that an IOC is in warm-up mode:
1. Apply an appropriate signal to the INP1, INP2, and/or PRS inputs.
2. Visually inspect the Power LED on the appropriate IOC. The LED is flashing
green in the Warm-up mode.
3. Type RTRV-ALM::IOC1; (or RTRV-ALM::IOC2; ). The TimeProvider responds
with a complied message indicating that the designated IOC is in alarm.
Locked Mode
The IOC enters and remains in the locked mode after it has completed the warm-up
cycle. The following actions occur when an IOC enters the Locked mode:
The Power LED on the IOC is green
An event is generated and stored in the event log
To verify that an IOC is in locked mode:
1. Visually inspect the Power LED on the appropriate IOC. The LED is continually
green when the IOC is tracking at least one input.
2. Type RTRV-LOG::IOC1:::EVT; (or RTRV-LOG::IOC2:::EVT; ). The
TimeProvider responds with a list of events related to the specified IOC. Look for
the entry with the text “Clock entered lock mode.”
