1 General description

1.1 Introduction

Description

The air dryer removes moisture from compressed air by cooling the air to near freezing point. This causeswater to condense. The condensate is automatically drained. The air is warmed up before leaving the dryer(approx. 5 ˚C (9 ˚F) below the incoming air temperature).

The electronic controller keeps the pressure dew-point stable at no load by opening or closing the solenoid valve of the hot-gas by-pass.

The condenser has a cooling fan controlled by a pressure sensor.

Description

Compressed air enters heat exchanger (101a) and is cooled by the outgoing, cold, dried air. Water in theincoming air starts to condense. The air then flows through heat exchanger/evaporator (101b) where therefrigerant evaporates causing the air to be further cooled to close to the evaporating temperature of therefrigerant. More water in the air condenses. The cold air then flows through separator (102) where all thecondensate is separated from the air.

The condensate collects in the Electronic Water Drain (EWD) (401) and is automatically drained. The cold,dried air flows through heat exchanger (101a), where it is warmed up by the incoming air to approx. 5 ˚C (9˚F) below the incoming air temperature.

Condensation in the air net cannot occur unless the air is cooled to below the pressure dew-point indicatedon the control panel.

1.3 Refrigeration system

Refrigerant flow diagram


Description

Refrigerant compressor (209) delivers hot, high-pressure refrigerant gas, which flows through condenser(202), where most of the refrigerant condenses.

Instruction book

2920 1822 00 9

The liquid flows through refrigerant dryer/filter (206) to thermostatic expansion valve (204) via sight-glass(211). The refrigerant leaves the thermostatic expansion valve at evaporating pressure.

The refrigerant enters evaporator (101b), where it withdraws heat from the compressed air by furtherevaporation at constant pressure. The heated refrigerant leaves the evaporator and is sucked in by refrigerantcompressor (209) via liquid separator (207).

The dryers are provided with a sight-glass (211). The sight-glass allows the refrigerant flow in the line to bechecked. During normal operation, the liquid flow must be clear. In general, vapour bubbles indicate a shortageof refrigerant. Note that fluctuations in the load may cause bubbles to pass in the flow for a short time. Thecentre of the glass is provided with a moisture indicator which is green when the liquid refrigerant is free ofmoisture. It will turn yellow when the refrigerant contains moisture, indicating that the refrigerant dryer/filter(206) needs to be replaced.

1.4 Automatic regulation system

Air and refrigerant flow diagram


Description

The condenser pressure must be kept as constant as possible to obtain stable operation, therefore:

Instruction book

2920 1822 00 11

• The controller stops and starts the cooling fans

When at partial or no load the dew-point pressure stays below the set-point, the controller opens solenoid valve (210) and hot, high-pressure gas is fed through hot-gas by-pass valve (208) to the evaporator circuit to prevent the evaporator temperature from dropping below 0 ˚C (32 ˚F).

2 Supply line3 Pilot valve4 Diaphragm5 Sensor6 Collector7 Valve seat8 Outlet

The condensate enters the Electronic Water Drain (EWD) via inlet (1) and accumulates in collector (6). Acapacitive sensor (5) continuously measures the liquid level.

The pilot valve (3) is activated as soon as the collector is filled up to a certain level. Diaphragm (4) opensoutlet (8), discharging the condensate.

When the collector has been emptied, the outlet closes quickly without wasting compressed air.

When the controller registers a malfunction, the red alarm LED on the control panel of the EWD starts flashing, a warning appears on the display of the controller and the electronic drain valve will automatically change to the alarm mode, opening and closing the valve according to a sequence as shown above. This condition continues until the fault is remedied. If the fault is not remedied automatically, maintenance is required.

Testing the Electronic water drain

Control panel, EWD

Briefly press the TEST button and check that the valve opens for condensate discharge.

Checking the alarm signal

• Press and hold the test button for at least 1 minute.• Check that the alarm LED flashes.• Check that a warning is generated on the display of the controller.• Release the test button.

Dryer protection

The unit is provided with a phase sequence relay (K25).

The high-pressure shut-down switch (S1) stops the compressor motor when the pressure in the refrigerantcircuit reaches the upper set-point of the switch.

After tripping:

• The switch must be reset manually by pressing its reset knob and by pressing reset key (//) on the controller (electronic controller).

The compressor motor has a built-in thermic protection. If the thermic protection trips, the compressor motorwill be stopped. The compressor will restart when the motor windings have cooled down, which may take upto 3 hours.

2 Air Logic controller

2.1 Air Logic controller

Control panel

General description

The electronic controller automatically controls the dryer, i.e.:

• keeps the pressure dew-point stable• stops the dryer whenever necessary• restarts the dryer when required

In order to control the dryer and to read and modify programmable parameters, the controller has a control panel provided with:

• LEDs indicating the status of the dryer• a display indicating the operating conditions or a fault• keys to control the dryer and to access the data collected by the controller• buttons to manually start and stop the dryer

In general, the controller has following functions:

• controlling the dryer• protecting the dryer• automatic restart after voltage failure (made inactive)

Controlling the dryer

The controller keeps the pressure dew-point stable at no load by opening or closing the solenoid valve of the hot-gas by-pass.

In order to keep the condenser pressure constant:

• The controller starts and stops the fan motor(s) as necessary.

Instruction book

2920 1822 00 21

Protecting the dryer

Shut-down

• In case the pressure in the refrigerant circuit is too high, the dryer will be stopped.• The dryer will also be stopped if there is an overload of a fan motor.

Warning

• A warning message appears if the EWD is malfunctioning.

Automatic restart after voltage failure

The controller has a built-in function to automatically restart the dryer if the voltage is restored after voltage failure. For dryers leaving the factory, this function is not activated. If desired, the function can be activated. Consult the Customer Centre.

If activated and provided the controller was in the automatic operation mode, the dryer will automatically restart if the supply voltage to the module is restored within a programmed time period.The power recovery time (the period within which the voltage must be restored to have an automatic restart) can be set between 15 and 3600 seconds or to ‘Infinite’. If the power recovery time is set to ‘Infinite’, the dryer will always restart after a voltage failure, no matter how long it takes to restore the voltage. A restart delay can also be programmed, allowing for example the dryer and the compressors to be restarted one after the other.

Overview

Text on figure

(1) Overview(2) Running Hours (green)(3) Real Time hours (blue)

Example for service level (A):

The figures at the left are the programmed service intervals. For Service interval A, the programmed numberof running hours is 4000 hours (upper row, green) and the programmed number of real time hours is 4000hours, which corresponds to six months (second row, blue). This means that the controller will launch a servicewarning when either 4000 running hours or 4000 real hours are reached, whichever comes first. Note that thereal time hours counter keeps counting, also when the controller is not powered.

The figures at the right 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 4000 running hours or 3976 real time hours to gobefore the next Service intervention.

Service plans

A number of service operations are grouped (called Level A, Level B, etc...). Each level stands for a numberof service actions to be carried out at the time intervals programmed in the electronic controller.

When a service plan interval is reached, a message will appear on the screen.

After carrying out the service actions related to the indicated levels, the timers must be reset.

From the Service menu above, select Service plan (3) and press Enter. Following screen appears:
