Operating instructions in accordance with the 97/23/EC Pressure Equipment Directive Operating instructions in accordance with the 97/23/EC Pressure Equipment Directive ® The DRYPOINT RA 1080-8800 compressed-air refrigeration dryer contains pressure equipment in the sense of the 97/23/EC Pressure Equipment Directive. Therefore, the entire plant needs to be registered with the supervisory authority if required in accordance with the local regulations.
Transport Transport Check the packaging for visible loss or damage. If no visible damage can be ascertained, place the unit in close proximity to the place of installation and unpack the device. During this procedure, the dryer must always remain in an upright position. The components may be damaged when the unit is tilted or turned upside down.
Installation Installation Place of installation Note! Ambient conditions! In the event that the dryer is not installed under suitable ambient conditions, the ability of the device to condense refrigerant gas is impaired. This can result in a higher load of the refrigerating compressor, and in a loss of efficiency and performance of the dryer.
Installation Installation plan - A - Air compressor Aftercooler Condensate separator Prefilter Bypass group Dryer Compressed-air tank - B - Final filter BEKOMAT condensate drain Installation type A is recommended when when the total consumption corresponds to the throughput rate of the compressor.
Installation Connection to the compressed-air system Danger! Compressed air! All works must only be carried out by qualified skilled personnel. Never work on compressed-air systems which are under pressure. The operator or the user must ensure that the dryer is never operated with a pressure exceeding the maximum pressure value indicated on the name plate.
Installation Electrical connections Danger! Supply voltage! The connection to the electric mains should only be carried out by qualified skilled personnel and must correspond to the legal provisions in force in your region. Prior to connecting the device, please check the name plate to avoid exceeding the indicated values. The voltage tolerance is +/- 10%.
Start-up Danger! Supply voltage and missing earth connection! Important: ensure that the plant is connected to earth. Do not use plug adapters at the power plug. Possible replacement of the power plug must only be carried out by a qualified electrician. Condensate drain Danger! Compressed air and condensate under pressure!
Start-up Initial start-up Note! The dryer must not be started up more than six times an hour. Wait at least five minutes prior to every restart. The user is responsible for the compliance with these provisions. Irreparable damage can be caused by starting up the device too often.
Start-up Start-up and shut down During short-term shut down (max. two to three days), it is advisable to leave the dryer and the control panel connected to the supply current circuit. Otherwise, it would be necessary at a restart of the dryer to wait two hours, until the oil in the compressor has reached the specified operating temperature.
11 Technical description 11.1 Control panel The control panel explained below is the only dryer user interface. reset info Main switch Electronic control unit DMC 24 Air and refrigerant-gas flow chart 11.2 Functional description Operating principle – All dryer models described in this manual function according to the same principle. The hot and moisture-loaded air is led into an air/air heat exchanger.
Technical description 11.5 Refrigerating compressor The employed refrigerating compressors are constructed by leading manufacturers. The hermetically sealed construction is absolutely gastight. The integrated safeguard protects the compressor against overheating and excess current. The protection is automatically reset as soon as the nominal conditions are reached again. 11.6 Condenser (air-cooled) The condenser is the component in which the gas coming from the compressor is cooled down, condensed and liquefied.
Technical description 11.14 Compressor crankcase heater During a longer downtime, the oil can intermix with the refrigerant. Therefore, "hydraulic shocks" may occur during the start-up of the compressor. To prevent this, a heating resistor was installed in the housing of the compressor which maintains a corresponding oil temperature when the control panel is switched on and the compressor is idle.
Technical description 11.15.2 Switching the dryer off Press for at least two seconds from any menu. The display shows 11.15.3 Indication of the operating parameters – Info menu The Info menu shows the dynamic operating parameters of the dryer. When the dryer is ON and you are not in other menus, press info for at least one second to access the Info menu.
Technical description 11.15.4 Indication of a service warning A service warning is an exceptional event and requires the attention of the operator/service technician. Such a warning will usually not stop the dryer (unless a high dew point parameter was adjusted to stop the dryer). When a service warning is active, the LED flashes.
Technical description 11.15.5 Alarm indication An alarm is an exceptional event which, to avert damage from to the machine and the operator, always leads to the disconnection of the dryer. When the alarm is active, the LED flashes. When the alarm was not automatically reset, it is stored and the LED is on (in any case, the dryer remains OFF).
Technical description 11.15.6 Display of the alarm memory – log menu The log menu includes a list of the last 10 alarms (only alarms, no service warnings). They appear in chronological order (LIFO logic). When the dryer is ON or OFF, and when you are not in another menu, press the button for at least one second to access the log menu.
Technical description 11.15.10 How to change operating parameters – SETUP menu The setup menu can be used to change the dryer’s operating parameters. Only qualified personnel must be allowed to access to the setup menu. The manufacturer is not responsible for malfunctioning or failure due to modification to the operating parameters. info With dryer ON or OFF and not in other menus, simultaneously press buttons for at least 5 seconds to enter...
Technical description 11.16 Electronically level-controlled BEKOMAT condensate drain The electronically level-controlled BEKOMAT condensate drain boasts a special condensate management which ensures that condensate is discharged safely and without an unnecessary loss of compressed air. This drain has a condensate collection container in which a capacitive sensor continuously monitors the liquid level. As soon as the switching level is reached, the capacitive sensor transmits a signal to the electronic control and a membrane solenoid valve opens to discharge the condensate.
