Check for low oil level, partially closed oil sup- ply valves, clogged oil filters. Check for oil loss or excess refrigerant charge. Check for condensation in transducer connector. Follow safe practices when using ladders. Check for closed valves or restriction in motor cooling lines. Measure the DC bus potential with a voltmeter while standing on a non-conductive surface and wearing insu- lated gloves V.
The detected fault message is maintained on the display until it is cleared by pressing the RESET softkey. Check that CCM transducer voltage reference is between 4. The UPC Open controller is protected by internal solid-state polyswitches on the incoming power and network connections. If pressure transducers are not installed, check for presence of resistors and jumpers on lower CCM terminal block J3.
Traces of vapor should be displaced with dry air or nitrogen and the work area should be well ventilated. MOST CODES require that upstream branch circuit protection be pro- vided to protect input power wiring.
Check VFD control power breaker, transformer and fuses. The total weight for Frames 6 and 7, including drive weight and enclosure, is lb. Check that VFD refrigerant cooling modulating valve is closing. CCN has signaled the chiller to stop. A type 2 non-configurable alarm condition exists and the drive cannot be started. The orifice looks like one of the O-ring face seal connectors and in fact is used as one of the connections on the coolant tubing. Remove any dirt or debris.
Check entering condenser water temperature and water flow rate. Check VFD Fault History for Values. Check for high lift or low load. When running, the drive continues to run. Drive cannot be started until fault condition is cleared. READ AND UNDERSTAND this manual and other applicable manuals in their entirety before proceeding.
Error Lights based on controller status. Do this again before start-up.
Check for sensor wiring and accuracy. Check for high Evaporator or Condenser approaches. This temperature dif- ference is great enough to be easily felt.
