Revision 1 –04.12.2015 8/28
EXAMPLE OF CONNECTION TO SECURITY PRESSURE SWITCH
Alarm related to security pressure switch A21 is joined to the lacking phase to all the digital inputs.
This is a shut off alarm: below you can find the connection drawing both to contactors 24Vac and/or 230Vac.
Contactors 230Vac
If the operation of the contactors and
solenoid valves comes through 230 Vac, the
digital inputs have to be connected to 12
Vac; next to the contact of the pressure
switch, place and energize an auxiliary
relay and put the contact in serie to
12 Vac (L) (see drawing on the right).
When the pressure switch is closed, the
auxiliary relay with contact closed supply
power to the digital inputs; the power
supply of the controller is connected before
the contact of the relay.
When the pressure switch opens, the
auxiliary relay opens power to the digital
inputs; the controller detects all the digital
inputs open and signal the alarm “SEC.
PRESSURE SWITCH”.
Contactors 24Vac
If the operation of the contactors and
soenoid valves come through 24 Vac, the
digital inputs have to be connected to 24
Vac (see drawing on the right); on this
way when the pressure switch opens due
to high pressure, 24 Vac lacks and
deenergize all the contactors, solenoid
valve and digital: the controller detects
all the digital inputs opened and signal
the alarm “SEC. PRESSURE SWITCH”.

CONNECTION SERIAL NET RS485
To connect a serial net you have to pay carefully attention to some executive aspects:
1) Use flexible cable, shielded, twisted 22 AWG type.
2) Connect D- and D+ to two conductors of same couple and 0 to a third one (if available) or both conductors of a
second couple.
3) Connect the cable’s shield to only one end of 0.
4) DO NOT CONNECT the cable’s shield to the electrical ground of the plant.
5) The net MUST NOT BE LONGER than 400 meters.
6) Max connectable units through serial net RS 485 is 32.
7) In case of connection via serial line RS485 you have to set the parameter C08 into menu 04 Compressor setup:
this is the number you need to combine to the recognition of the controller.
8) The units on serial net RS485 must be connected without any reversal: pole D+ to D+, pole D- to D-, pole 0 to 0.
9) In case of connection with more than 2 units it is necessary to provide only one line without any deriving.
At the terminal both starting and ending the net it is possible to place (in parallel to D- and D+) a termination
resistance 120 Ohm.
In the picture below you can see the connection of 4 units on serial net RS485 by using a shielded cable with two
twisted couples.
NOTES ON THE WIRING: wrong wiring can damage both the controller and other devices connected to the
serial port.
WARNINGS TO THE WIRING RS485
1) The cable must be placed into a TRUNK SEPARATED by power cables and any potentially dangerous cables as
lighting plant and so on.
2) DO NOT PLACE signal cables next to power bar, lighting lamps, antennas, transformers;
3) Keep signal cables FAR 2 METERS MINIMUM from units with heavy inductive (distribution cabinet, motors,
inverter).
4) Don’t pull the cables with a strength over 12 Kg; stronger strength can damage the wires and reduce the signal
transmission on the line.
5) DO NOT: twist, knot, crush or fray the conductors.
6) Do not make any joints between lengths of cable: always use only one cable to connect any single unit to each
others. Strip the end part carefully, do not crush the cable next to core-hitches or safety supports.
7) Always respect the position of the colors at the both sides of the connection.
Once the wiring is complete, visually and physically check the cables are undamaged and properly placed

NOTES:
C01–RESTART: in case of power off, by selecting “Man”, the compressor doesn’t start automatically and the display
visualizes "POWER OFF"; by selecting “Aut.”, the compressor restart automatically according a delay time set Wt5: during
this time the display visualizes the “WAIT”.
If you change the default setting, it is recorder into the alarm buffer and you can cancel it by general reset only.
C05–SAFETY: if you set “YES”, once the timer “CAF” will be over, the display visualizes the message “Shut-off for safety”;
you can erase it into this parameter only and set it as “Safety = NO”; in this case the alarm code change into “Change air
filter”.
C07–MULTIUNIT OPERATION: set “0”, the compressor works by standing alone.
Set “1”, the compressor communicates with a second unit via serial RS232 as Master/Slave (see related working program)
and the controller visualizes the parameters 07.1 e 07.2.
C07.1–TIMER MASTER / SLAVE: time to switch Master into Slave; if the difference of working hours between the two
compressors is bigger than the setting of this parameter, the unit with more hours will not be Master as long as the other
will reach the same.
C07.2–TIMER SLAVE: after power ON, if the Master unit has not reached the stop pressure until the time setting in this
parameter, the Slave will start to support.
C08–COMPRESSOR Nr.: in case of Master/Slave enabled, the compressor set as 1 will be the Master unit.
C09–SERIAL NUMBER: LCD visualizes the serial number on the third lower right side row from the bottom.

You can select the characters by the arrows buttons; by shift forward to the next character or enter a new one, by ESC
shift back to the previous one; you can delete the editing by pushing ESC when the cursor in on the first character.
You can save the data by enter two SPACE in a row or by reaching the max. number of characters (15).
C17–Shut-off for C—h: alarm related to the maintenance timer C—h (check compressor); if you set “YES”, 100 hours
before the timer is over, the compressor stops showing alarm STOP FOR AL32 –CHECK COMPRESSOR.
You can reset the alarm and restart the compressor for the next 100 hours and every 50 working minutes the display
remind to maintenance C—h.
Once the residual 100 working hours are over, the compressor will stop again; you can reset such alarm by resetting the
maintenance timer only.
C18–Output 4/20mA: allow to upload factory default parameters in menu M1-9. Two different default set are provided
according regulation is related to the working pressure or air end temperature.
C22-C23: These parameters are enabled if one of the relay is configured as per setting value 7 (lubricating). In this case
the relay allows automatic lubricating according the setting on C22 and C23. The time to lubricate is calculated on BL timer
that is not visible for the reason used on this function.

NOTE:
If you set the parameter a value different from 0 on the parameter DR0, you enable the inverter operation via RS485 and
related alarms 60, 61,62.
After the last parameter DA9 comes “Setup Drive” that allows to start the setting of the inverter; it means to send the
parameters from DR1 to DA9 to the inverter. Moreover all the required settings to make the system Logik26S+Drive
working, such as drive PID enable, drive PID setpoint and feedback source and so on, are programmed to the drive also.
Confirming “Setup Drive” the LCD visualizes the following screen:
In the middle of the LCD is visualized the drive status.
When the download is in progress, above the drive status comes the progress status (in percentage) of the setup.
Pressing the setup start. Setup required approximately 5minutes.
Pressing R the setup abort and it is possible to go back to menu M1-8.

M1-9 ANALOG OUTPUT
This menu is visualized only if the safety pressure transducer has been configured in the menu Compressor setup
(parameter C18 different from 0).
The analog output is determined by a PID calculation.
The analog output can be eventually connected to the electrical motor inverter or fan motor inverter. Parameter C18 must
be set 1 for electric motor or 2 for fan motor.
In case of electric motor the regulation is made by the pressure. The setpoint of the PID calculation is placed in the middle
of the interval between start pressure WP3 stop pressure WP4. Example: WP3=7bar and WP4=8bar, setpoint will be 7.5bar
and PID will try to keep the working pressure around such reference value by increasing the inverter output (frequency as
well) in case the pressure is lower than the set and decreasing in case the pressure is higher.
In case of the fan motor the regulation is made by the temperature. The sepoint of the PID calculation is the value set on
WT3 (fan start). PID will try to keep the air end temperature around such reference value by increasing the inverter output
(frequency as well) in case the temperature is higher than the set value and decreasing in case the temperature is lower.
Menu M1-9 allows to visualize/set the parameters related to the PID regulator.

NOTE:
For all the above parameters two default set are provided according the way of control (set on parameter C18).
PID output (limited to the interval 0..1) is transposed to output current: frequency FR1 (PID output=0) correspond 4mA,
frequency FR2 (PID output=1) correspond 20mA.
You have to set the frequency reference on the inverter so that 4mA/20mA input correspond the frequency ranged you
need. You have to set such range both on parameters FR1 and FR2.
PT3 is the duration of the acceleration/deceleration time in case the compressor has to reach the download status; in this
case inverter reaches the minimum frequency FR1 according ramp PT3.
In case of compressor loading the ramps are PT1, while the speed goes up and PT2 while speed goes down.
In case of pressure regulation, PM1 alters the integrating effect of the error on the setpoint; specially integral time PI2 is
multiplied for PM1 when the pressure is over setopint.
Set PI2 or PI3 zero, the related integration or derivative action is disabled.

The counting is related to the ON time of the line contactor (RL1) and goes on backward: when the counting reaches 0, the
display shows the related message and goes on as negative counting.
The storage of the hours comes every 15 minutes; if the power goes off during the counting such 15 minutes are missed.
If parameter C--his set 10.000, the alarm “CHECK COMP.” is not enabled.
If parameter C-BL is set 29.999, the alarm “BEARING. LUB.” is not enabled (bearing lubricating).
By changing the set value than the count in progress is re-calculated.
Example: CAF, set 2000h, the counter is 1600, it means 400h has passed from reset. If yu change the set, for example
3000, the counter will change into 2600.
M1-11MAINTENANCE LIST
