  • Page 9: Section Ii - Description

    The compressors can be delivered with or without integrated refrigerant air dryer. QOF is the type designation of the compressor variant without integrated dryer. On QOF, the compressed air of each compressor module flows via an individual check valve to a common air cooler and leaves the compressor via the air outlet valve. QOF with dryer compressors are QOF compressors provided with a refrigerant air dryer, integrated in the bodywork. The dryer removes moisture from the compressed air by cooling the air to near freezing point and automatically draining the condensate. QOF 30 with dryer, front view Quincy Compressor...
  • Page 10 Section II - Description Electronic controller Emergency stop button Hour meter QOF 30 with dryer, rear view Compressor module Refrigerant dryer Air cooler Compressed air outlet valve Compressor element operating principle Each compressor element consists of a fixed scroll shaped housing and a scroll shaped rotor. Air enters the compressor element through inlet opening (1). Once the air is drawn in, the orbiting scroll (4) seals the inlet opening and forces the air into a continuously decreasing space. As scroll (4) keeps orbiting, this process of compression is constantly repeated, resulting in discharging of oil free compressed air through outlet opening (3). Quincy Compressor...

  • Page 15 The complete electrical diagram is available in the electric cubicle of the compressor. For connection of the supply wires, please see section Electrical connections. Temperature protection The compressor is equipped with an ambient temperature sensor. The sensor creates a warning message on the controller if the ambient temperature rises above 40 °C (104 °F). If the ambient temperature reaches 45 °C (113 °F), the compressor is stopped. Condensate drain connections Automatic condensate drain outlet Manual condensate drain valve Ambient temperature sensor Each compressor element is protected by a PT 1000 sensor (6) in the outlet pipe. The sensor is connected to the electronic regulator. When the maximum temperature is exceeded, the compressor element is stopped during 2 minutes before it can restart. If this happens 2 times within a time span of 2 hours, the element will be stopped during 10 minutes. If the compressor element stops a third time within the 2 hours time span, the element will be shut down and must be reset manually. Quincy Compressor...

  • Page 17 The refrigerant enters evaporator (2) where it withdraws heat from the compressed air by further evaporation at constant pressure. The heated refrigerant leaves the evaporator and is sucked in by the compressor. The condenser (6) pressure must be kept as constant as possible to obtain stable operation. Fan control switch (P) therefore stops and starts the condenser cooling fan. If, under partial or no load, the evaporator (2) pressure drops to approximately 2.25 bar(e) (32.63 psig), the hot gas bypass valve (5) opens and hot, high-pressure gas is fed to the evaporator circuit to prevent the evaporator pressure from dropping any further. Automatic drain The dryers are equipped with an electronic condensate drain (EWD). The condensate from the condensate trap accumulates in a collector. When the condensate reaches a certain level, it is discharged through the drain outlet (1). The condensate can also be drained by pressing the test button (2). The drain filter can be cleaned by opening the manual drain valve (3), see section Preventive maintenance schedule. Quincy Compressor...

  • Page 44 Service Overview Service plan Next service History • Scroll through the items to select the desired item and press the Enter key to see the details as explained below. Overview Text on image Overview Running Hours Real Time (hours) Reset Example for service level (A): The figures at the left are the programmed service intervals. For Service interval A, the programmed number of running hours is 500 hours (upper row) and the programmed number of real time hours is 2190 hours, which corresponds to one year (second row). This means that the controller will launch a service warning when either 500 running hours or 2190 real hours are reached, whichever comes first. Note that the real time hours counter keeps counting, also when the controller is not powered. A new algorithm is implemented for a better protection of the compressor elements. The running hours will be recalculated depending on the ambient temperature. A compressor continuously running in an ambient temperature between 30 °C (86 °F) and 35 °C (95 °F) is working in harder conditions than an element running at 20 °C (68 °F). Therefore a service done earlier (a time reduction of 30 % is applied in this temperature zone) will protect the element in a better way. In the zone between 35 °C (95 °F) and 40 °C (104 °F), the time reduction is 60 %. The figures within the bars are the number of hours to go till the next service intervention. In the example above, the compressor was just started up, which means it still has 500 running hours or 2187 hours to go before the next Service intervention. Service plans A number of service operations are grouped (called Level A, Level B, etc...). Each Quincy Compressor...

  • Page 91 Section VII - Adjustments and servicing procedures Replacement of the outlet pipe (only applicable to QOF 20) Description The scroll element outlet pipe (1) contains a plastic insert (3). Due to the heat of the compressed air, the plastic insert can become brittle. Therefore it is recommended to replace the outlet pipe together with the insert when that is the case. Both parts are available as a kit (outlet pipe set). See the Spare Parts List for part number. The outlet pipe set contains two parts: • The plastic insert (3) • The metal outlet pipe (1) Procedure 1. Stop the compressor, depressurize and switch off the voltage. 2. Loosen the coupling (3) while fixating the nipple (2) with a spanner. 3. Remove the outlet pipe together with the nipple 4. Fit the nipple to the new outlet pipe and tighten. Use only PTFE tape. 5. Fit the plastic insert in place as indicated on the drawing and assemble the outlet pipe with a maximum torque of 10 Nm (7.4 lbf.ft) plus maximum one turn (360°).

  • Page 99 • Size of the PE cable: use following rule of thumb: • For supply cables up to 16 mm²: same size as supply wires • For supply cables between 16 mm² and 35 mm²: 16 mm² • For supply cables larger than 35 mm²: half the size of the supply wires Always check the voltage drop over the cable (less than 5 % of the nominal voltage is recommended)! Example: For QOF 15 T 400 V 50 Hz IEC, Itot = 52 A, ambient temperature is 40 °C, recommended fuse: maximum 63 A. • In case of single supply cables (3 phases + PE - configuration (1)): • I = 52 A + 10 % = 52 x 1.1 = 57.2 A • The table for installation method B2 allows a maximum current of 54 A for a 16 mm² cable. For a cable of 25 mm², the maximum allowed current is 70 A, which is sufficient. Therefore, use a 3 x 25 mm² + 16 mm² cable. If method C is used, 16 mm² is sufficient (maximum 66 A at 40 °C). Use a 3 x 16 + 16 mm² cable. • Install 63 A fuses. • In case of parallel supply cables (2 x 3 phases + PE - configuration (2)): • I = (52 A + 10 %)/2 = (52 x 1.1)/2 = 28.6 A • For a cable of 6 mm² and installation method B2, the maximum current is 30 A x 0.8 = 24 A, which is insufficient. For a cable of 10 mm², the maximum allowed current is 50 A x 0.8 = 40 A. So 2 parallel cables of 3 x 10 mm² +10 mm² are sufficient. In case of installation method C, the maximum current of a 6 mm² cable at 40 °C is 36 A x 0.8 = 28.8 A. 2 parallel cables of 3 x 6 + 6 mm² will be sufficient. • Install 32 A fuses on each cable..
