The control system monitors the status of the compressor parameters by using sensors,
transducers and protective devices that are listed in Table 2 and 3.The presence of the
sensors in the system depends on the particular compressor configuration and can't
exceeds the amount of three analogue sensors and eight digital sensors.
The control system is equipped with the 6 relay outputs monitored by the PLC controller.
Each of them can be set to one of several functions that are presented in Table 3. A part of
the outputs is closely related to the compressor configuration and its functions can not be
changed. The relay outputs are switched off when the PLC is without power or is in STOP
mode.

Table 4 Relay's outputs functions.
Name ON State
Fault The relay is switched on when the controller registers an event causing
the compressor to stop.
No fault The relay is switched on when the controller registers no event causing
the compressor to stop.
Load solenoid The relay is switched on when the compressor is to discharge.
Ready The relay is switched on when the compressor has been activated.
Heater The relay is switched on when the compressor is not running and when
the oil temperature is lower than the temperature set point. The relay is
switched off when the temperature rises by the set point value above the
heater activation temperature or when the compressor starts.
Dryer The relay is switched on before the compressor starts, and the
compressor itself is waiting to start for a preset dryer start time. The relay
is switched off after a preset time since switching the compressor off.
Operation The relay is switched on when the compressor is running.
Service The relay is switched on when it is necessary for the compressor to
undergo servicing.
Compression The relay is switched on when the compressor is compressing.
Slave
compressor
The relay is switched on when the compressor is running, and the air
pressure is lower than the set threshold. The relay is switched off when
the air pressure is higher than the set threshold or when the compressor
switches off.
Condensate

The relay is switched on at a certain time for a certain time. The time
between activations is counted only when the compressor is running.
Softstart start The relay is switched on when the compressor is to run.
Star contactor The relay is switched on when the compressor is starting.
Line contactor The relay is switched on when the compressor is to run.
Delta contactor The relay is switched on after the compressor has started.
Fan The relay is switched on after the compressor has started, and switched
off when the compressor is not running.
Temperature fan The relay is switched on when the compressor is running and the oil
temperature is higher than the set switch-on threshold. The relay is
switched off when the oil temperature is lower than the switch-off
temperature, or when the compressor is not running.
Always ON The relay is switched on when the PLC is operating in RUN mode.
Always OFF The relay is never switched on.

3. Algorithm of the compressor operation
The compressor may be inactive (the compressor is not started when pressure drops below
the switching on pressure threshold)or active (the compressor is started when pressure
drops below the switching on pressure threshold). Activation of the compressor is carried out
in different ways depending on the selected operation mode. Below there are presented the
available operation modes including the ways of the compressor activation:
•AUTOmode – the compressor activation requires pressing the START key (active
only in this mode)on the control panel (pressing the STOP key will deactivate the
compressor)
•REM mode – the signal for the compressor activation is closing the external
potential-free contact connected to the compressor terminal block (the contact
opening results in the compressor deactivation)
•CAL mode – the compressor activation and deactivation occurs according to the
setting calendar
•NET mode - the compressor activation and deactivation occurs according to the
commands sent in the Modbus TCP protocol
The signal that causes the compressor to start and its loading is the signal from B3
transducer. Fig. 2 presents an example diagram of pressure changes in time with indicated
states of the compressor operation.
Fig. 2 Algorithm of the compressor operation.
The above diagram assumes that the compressor is active all the time. If the present
pressure (PA) drops below the switching on pressure threshold (PL),the compressor will
start and change from the stop state (0) to the compression state (2).

The operator panel supports four menu languages: Polish, English, Russian and German.
To change the language, press the flag symbol placed in the upper left corner of the menu
screen. Switching is sequential and cyclical. Changing the language also changes the flag
symbol.

4.7 Record of events
The controller records many events that are saved together with event occurrence time in
the memory of the control panel.If a number of events is higher than the available memory,
part of them is erased to make space for new records. Moreover, the controller displays
currently active events.To view records, use the list of events screen that is shown in Fig. 8.
When an event occurs, the status LED changes their colour in accordance with the Tab.
5.To identify an event occurred, go to the screen of active events by entering the menu and
clicking the key number 3 described as the event or by clicking events icons on the main
screen.

Texts on the list of active events remain visible until a user confirms reading of events with
the key located under the list.
