84Control Test — The Control Test feature can check all thethermistor temperature sensors, pressure transducers, pumpsand their associated flow devices, the guide vane actuator, andother control outputs such as tower fans, VFD coolingsolenoid, shunt trip relay, oil heaters, alarm relay, and hot gasbypass. The tests can help to determine whether a switch isdefective or a pump relay is not operating, as well as otheruseful troubleshooting issues. During pumpdown operations,the pumps are energized to prevent freeze-up and the vesselpressures and temperatures are displayed. The Pumpdown/Lockout feature prevents compressor start-up when there is norefrigerant in the chiller or if the vessels are isolated. TheTerminate Lockout feature ends the Pumpdown/Lockout afterthe pumpdown procedure is reversed and refrigerant is added.LEGEND TO TABLES 16A-16JTable 16 — Alarm and Alert MessagesA. MANUAL STOPB.
