General safety instruction instructionss
Loss or decrease of plant safety !
DANGER
Retrofitting or modifications on the system can reduce its level of safe- ty! The results could be serious personal, material or environmental damage. Possible retrofitting or modifications on the system with equipment components from third party manufacturers must there- fore first be cleared by us.
Loss of protection from contact to hazardous zones!
DANGER
The side panelings of the system are a part of the contact protection system to protect personnel from ventilator wheels that start up auto- matically, moving machine parts, hot surfaces and dangerous voltag- es! Furthermore, they are required for sound insulation for the cool- ing air conduction. Therefore they may not be removed in the normal operating mode of the system.
Injuries caused by ventilator wheels that start automatically, moving machine parts, hot surfaces or escaping coolant mist!
DANGER
Installation, service or repair work on the components of the system must, if not otherwise described, be categorically carried out only on a switched-off, sufficiently cooled-off and pressure-free system! The system must be secured against an illicit or accidental switching-on. The shut-off device for the compressed air grid must be closed. If measuring or testing work is required on the electrical components while the system is in operation, they must be carried out by electri- cians observing all the relevant safety regulations.
6
Damage to the sense organs!
DANGER
Compressed air streams may not be directed towards persons. When applying compressed air, dust particles can be raised by the air st- ream. Therefore, when working with compressed air, protect your eyes with safety glasses.
Loss or decrease of plant dependability! Only original spare parts and lubrications may be employed!
NOTICE
We recommend that a set of service parts subject to wear be kept on stock, in order to guarantee high plant availability. Our customer service would be glad to help you with your selection. Tel: (+49) 0180 5258700.
Damage to the system may result in environmental damage! Before the initial commissioning, the system must have been correctly installed according to Chapter 6! NOTICE
Plants greater than 100 kW may be taken into operation by qualified personnel. Dispose of all used or defective materials in a proper way! This is especially true for components/materials containing cooling liquid. Please note that the accumulated condensation containing cooling liquid may not enter the sewerage system! We offer an appropriate coolant/water separator for condensation processing.
Compressed air receivers require regular technical inspections! Please notify the commissioning of the system at the technical inspection authority responsible for you. They will inspect the system and provide a receiver test book.
Document all the activities carried out (e.g. in some table format). 7 Carry out the activities in all of the following chapters in the order given.
2. Functional description 2.1
Drive
The frequency converter in the switching cabinet supplies the electric motor with power. For the operating principle of the frequency converter converter,, please refer to the instructions in the switching cabinet. The electric motor drives the compressor stage via a flexibly supported coupling.
2.2
Air path
Fresh air supplied by the integrated cooling air ventilator is filtered through the intake filter(s). The air is then directed via the intake regulator into the compressor stage, where it is compressed to the final compression pressure together with injected coolant. In the coolant reservoir, the compressed air is separated 98 % from the cooland and the downstream coolant separator removes the remaining coolant from the compressed air. The air then flows via the minimum pressure one way valve into the compressed air afte rcooler and is cooled down to 10 - 15 C above the ambient temperature before it leaves the compressor through the compressed air port. °
The intake regulator opens shortly after the compressor has started up for generating compressed air. It closes when the compressor changes over to off-load operation and/or comes to a standstill and unloads the system via the relief valve. 2.3 2. 3
Cool Co olan antt cir circu cula lati tion on
The coolant is sprayed into the compression stage and has the following functions: •
heat removal heat removal of the the tempera temperature ture inc increas rease e caused caused by by the comp compres ressio sion n process
•
sealing sealin g lubric lubricati ation on of the the rotors rotors to each each other other and and to the the housi housing ng with with a coolant film
•
bearing lu lubr briication
• noise dampening The coolant leaves the compression stage together with the compressed air as a hot coolant return air mixture. The coolant is separated from the compressed air into the coolant container by the coolant separator separato r and when separated, it streams to the coolant heat exchanger. The coolant temperature regulator mixes the cooled down coolant with the coolant heat exchanger-bypass hot coolant as defined by the setpoint temperature. Lastly, the coolant filter cleans the coolant, before it is again injected in the compression stage. If desired by the customer, an additional heater can be installed in the coolant container either originally or subsequent to purchase. It prevents condensation damages dam ages in the case ofcold or damp compressor plant environments, for example.

2.4
Cooling
The compressed air after-cooler of the coolant heat exchanger is cooled either by •
a bui builtlt-i -in n coo cooliling ng ai airr ven ventitila lato torr or or
• water cooling. The electric motor is always cooled by its own ventilator fan. In the case of water-cooled compressors, a fresh air ventilator additionally ensures sufficient fresh intake air for the removal of radiated heat.

The text “AUTOMATIC” is displayed in the basic display. After reaching the switch-off pressure, the system goes into idling mode (after-run time) for the duration of the after-run time and in the basic display; the text “afterrun time” appears with the respective residual time. At the conclusion of the after-run time, the motor switches off. The compressor can be started up automatically at any time after falling below the switch-on pressure. Operation mode “Load/Idling”
The text “LOAD/IDLING” is displayed displa yed in the basic display. The compressor switches between full load run and idling, which means that its after-run time is unlimited.
Operation mode “Automatic Optional”
The text “AUTOMATIC OPT.” OPT.” is displayed in the basic display. After reaching the switch-off pressure, the system goes into idling. After 10 and after 40 seconds sec onds the grid pressure is measured. If the pressure drops above the threshold “Max. pressure drop”, then the system is in the idling state for the duration of the after-run time. In the basic display, the text “After run” appears with the residu al time as defined. If the value lies below the threshold “Max. pressure drop”, then the system switches off after completing the standstill time. Max. switching cycles
If the number of the maximum possible switching cycles per hour for the motors is exceeded, then the compressor temporarily switches to the operation mode load/idling.

Switching times as well as pressure times can be programmed with the timer independently of each other. When programming switching times, the compressor need no longer be manually switched on and off. This is to prevent the possibility that the compressor might for instance start up itself at night in order to compensate for loss in the compressed air grid. For a limited time, deviating values from the preset limit values (see Chapter 5.3.4.1) can be set for the switch-on and the switch-off pressure. In this way only the minimal required operating pressure is always generated so that energy is saved.

StartStar t-up up lub lubri rica cati tion on of of the the compressor stage
After an extended standstill time, for example between factory delivery and commissioning or during a longer company vacation, there might no longer be any coolant in the rotor chamber of the compression stage. This coolant is absolutely necessary for bearing and rotor lubrication in the startup phase.
1. Before switch switching ing on the compressor compressor plant, fill approx. approx. 0.2 liter liter coolant coolant into the filler screw of the intake regulators. 2. Rotate the compressi compression on stage only by hand in rotatio rotational nal direction direction until until the noticeable resistance dwindles and the coolant passes through the compression stage. 3. Finall Finallyy, tighten tighten the fille fillerr screw of the intake regula regulators tors (05). (05).
36 If no extra coolant is available (only coolant of the same variety may be employed!), the coolant can be taken from the coolant drain. If the system is employed only very irregularly or shut down weeks on end, it should run an hour in idling mode once a week in order to avoid corrosion damage caused by standing condensation.

The absorption capacity of water humidity in the air • falls with increasing pressure • rises wi with in increasing te temperature. Sufficiently high compressor temperature guarantees that the intake air humidity does not precipitate as condensation. The frequent switching on and off of the compressor can result in the compressor not achieving the required operating temperature.
Condensation in the coolant circulation can lead to damages to the compressor. If you have determined that there is condensation in the coolant container, immediately get in touch with customer service! NOTICE
Condensation damages lead to the loss of the guarantee!
Since water is heavier than coolant, after extended standstill times (e.g. on a weekend) the condensation collects in the bottom of the coolant containers. It can be simply drained off by the discharge drain.
