water in the air condenses. The cold air then flows through separator (3) where all the condensate from the air.The cold, dried air flows through heat exchanger (1) where it is warmed up by the incoming air.The condensate is automatically drained by the electronic condensate drain (9).

Refrigerant circuit

Compressor (4) delivers hot, high-pressure refrigerant gas which flows through condenser (6) whthe refrigerant condenses.The liquid flows through liquid refrigerant dryer/filter (7) to capillary tube (8). The refrigerant lecapillary tube at evaporating pressure.The refrigerant enters evaporator (2) where it withdraws heat from the compressed air by further eat constant pressure. The heated refrigerant leaves the evaporator and is sucked in by the compreThe condenser (6) pressure must be kept as constant as possible to obtain stable operation. Fan con(P) therefore stops and starts the condenser cooling fan. If, under partial or no load, the evaporator drops to a pproximately 2.25 bar(e) (32.63 psig), the hot gas bypass valve (5) opens and hot, high-prgas is fed to the evaporator circuit to prevent the evaporator pressure from dropping any fur ther.

Condensate drain system

The dryers are equipped with an electronic condensate drain (EWD). The condensate from the cotrap accumulates in a collector. When the condensate reaches a certain level, it is discharged thrououtlet (1).The condensate can also be drained by pressing the test button (2).

3 Electronic regulator

3.1 Electronic regulator Control panel

Introduction

The regulator performs following functions: Controlling the compressor Protecting the compressor Monitoring components subject to service

Automatic restart after voltage failureControlling the compressor

The regulator keeps the net pressure within programmable limits by starting and stopping the commodules, depending on the air consumption. The regulator also distributes the running time amoncompressor modules, taking into account the availability and number of running hours of each comodule.When the compressor has stopped automatically and the net pressure decreases, the regulator wilcompressor module before the net pressure has dropped to the starting pressure to prevent the nefrom falling under the programmed minimum level.

Protecting the compressor

If one or more compressor modules are shut down due to a protection function, a warning messashown on the display.The compressor will be shut down in case the temperature sensor trips.

Monitoring components subject to service

A number of service operations are grouped in plans (called Service plans A, B and D).Each Service plan has a programmed time interval. If a time interval is exceeded, a message willthe display to warn the operator to carry out the service actions belonging to that plan.

Automatic restart after voltage failure

The regulator has a built-in function to automatically restart the compressor if the voltage is restovoltage failure. For compressors leaving the factory, this function is made inactive. If desired, thecan be activated. Consult Atlas Copco.

If activated and provided the regulator was in the automatic operation mode, thecompressor will automatically restart if the supply voltage to the module is restoredwithin a programmed time period.

The power recovery time (the period within which the voltage must be restored to havean automatic restart) can be set between 15 and 3600 seconds or to infinite. If thepower recovery time is set to infinite, the compressor will always restart after a voltagefailure, no matter how long it takes to restore the voltage. A restart delay can also beprogrammed, allowing e.g. two compressors to be restarted one after the other.

3. Delivery pipe.The pressure drop over the air delivery pipe can be calculated as follows:p = (L x 450 x Qc1.85) / (d5 x P), withd = inner diameter of the pipe in mm

p = pressure drop in bar (recommended maximum: 0.1 bar (1.5 psi))L = length of the pipe in mP = absolute pressure at the compressor outlet in bar Qc= Free air delivery of the compressor in l/s

4. Ventilation: The inlet grid(s) and ventilation fan should be installed in such a way that any recof hot cooling air to the inlet gratings of the compressor/dryer is avoided.The air velocity to the grid(s) has to be limited to 5 m/s (16.5 ft/s).Maximum allowable pressure drop over cooling air ducts is 50 Pa (0.12 in WC).When 50 Pa is exceeded, a ventilation fan is needed at the outlet of the cooling air ducts. The air temperature at the compressor intake opening is 40 C (104 F), the minimum is 0 C (32 Alternative 1 and 3: The required ventilation to limit the compressor room temperature can befrom :Qv = 0,92 N /twithQv = required ventilation capacity in m3/s N = shaft input of the compressor in kWt = temperature increase in the compressor room in CAlternative 2 and 4: The fan capacity should match the compressor fan capacity at a pressure to the pressure drop caused by the cooling air ducts.

A DD filter for general-purpose filtration. The filter traps solid particles down to 1 micron. A PD filter for filtration down to 0.01 micron. A PD filter must always be installed downstrfilter.

It is recommended to provide bypass pipes and valves across the filters in order to isolate the filmaintenance without disturbing the compressed air delivery.

4.3 Electrical connections

Attention

The electrical installation must correspond to the local codes. The mains supply andearthling lines must be of suitable size.The installation must be earthed and protected by fuses in each phase. An isolating switchshould be installed near the compressor.Make sure that this switch is open to isolate the compressor from the mains beforecarrying out any connection.To preserve the protection degree of the electric cubicle and to protect its componentsfrom dust from the environment, it is mandatory to use a proper cable gland whenconnecting the supply cable to the compressor.
