6.5.7.2. Annunciator Alarm. The solid-state alarm annunciator panel is on the end of the PCP. It
contains small windows (about 25 millimeters by 38 millimeters [1 inch by 1.5 inches]) arranged
in rows and columns with alarm points engraved on them. Typical examples are LLA, HLA,
HHLA, pump failure, and microprocessor system faults. In addition to the windows illuminating
and flashing, there are two different audible alarm horns to alert personnel to the emergency. One
is a vibrating horn and the other is a resonating horn. Should an alarm condition occur, the visual
indicator flashes and the horn sounds. This condition must be acknowledged by pressing the
acknowledge button. This causes the alarm to stop and the flashing indicator to show a steady
light. The indicator will stay lit until the alarm condition is rectified. Should another alarm occur,
the process would be the same.
6.5.7.2.1. Vibrating Horn Alarms. The following conditions will cause the vibrating horn to
sound (system fault alarm is initiated upon detection of system fault):
6.5.7.2.1.1. Pump #1 failure.
6.5.7.2.1.2. Pump #2 failure.
6.5.7.2.1.3. Pump #3 failure.
6.5.7.2.1.4. Pump #4 failure.
6.5.7.2.1.5. System 1 fault.
6.5.7.2.1.6. System 2 fault.
6.5.7.2.1.7. Product recovery tank OV closed.
6.5.7.2.1.8. Product recovery tank leak.
6.5.7.2.1.9. High-level, product recovery tank.
6.5.7.2.1.10. High-level, oil/water separator.
6.5.7.2.1.11. High-level, operating tank #1.
6.5.7.2.1.12. High-level, operating tank #2.
6.5.7.2.1.13. High DP, receiving F/S.
6.5.7.2.1.14. Engine generator fault.
6.5.7.2.2. Resonating Horn Alarms. The following conditions will cause the resonating horn
to sound:
6.5.7.2.2.1. Emergency stop.
6.5.7.2.2.2. Low-level, operating tank #1 (if the outlet valve is not fully closed).
6.5.7.2.2.3. Low-level, operating tank #2 (if the outlet valve is not fully closed).
6.5.7.2.2.4. High-high-level, operating tank #1.
6.5.7.2.2.5. High-high-level, operating tank #2.
6.5.7.3. Pressure/Flow Recorders. Mounted on the PCP is a three-channel, continuous-plotting,
two-speed strip recorder. It uses three pens of different colors to record system activity. One pen
records system pressure (0 to 300 psi), another is for issue flow rates (0 to 9085 liters per minute
[0 to 2400 gallons per minute]), and the last one records return flow rates (0 to 3028 liters per
minute [0 to 800 gallons per minute]). The strip moves at either 25 millimeters (1 inch) per hour
