Chapter 1 - General description Selecting the language: • Open the menu by pressing on F1 (pushbutton at the rear of the PCI) • Select the required language using key F3 • Exit the menu using key F1

1.1 - General 1) General description The PCI07 is a micro-processor-equipped electronic module ® ® used to start and stop the ROLLAIR , to manage ROLLAIR faults and alarms, generate information on the operating status, and control condensate drain-off and remote transmissions and remote control. The PCI07 executes the following functions in particular : • Management of 2 anaputs: a temperature probe and a pressure sensor • Programming of compressor start-up and shutdown • Control, fault reporting and remote display of compressor operating status (option) • Automation of alternating operation between several compressors (option) • Timed On/Off management of a dryer (according to parameters)

2) Emergency stop, time-delayed stop WARNING: All compressors fitted with an electronic management board PCI07 must be provided with an emergency knock off push button which stops the compressor and the dryer. WARNING: The compressor shutdown time can be delayed by pressing the PCI07 O key, although there is a minimum of 30 seconds noload operation prior to full machine shutdown. The shutdown phase is indicated by the "STOPPING" and the green LED associated with the | key.

3) Analog sensors The PCI07 manages 2 analogue measurement channels to measure the service pressure (machine outlet) and the oil temperature (compression unit outlet).

• On (|) • Stop (O) • Stopped under pressure (F2) • Reset (F3) • Scrolling (F4) A connector situated behind PCI07 can be used for compressor remote control (option).

2) Data The PCI07 display and the Leds provide: • display of the operating status of the compressor at a given instant, • display of maintenance messages (alarms, defects, etc.) • display of compressor control parameters.

3) Regulation The PCI07 executes compressor regulation. These functions include: • control of no-load operation as soon as the pressure measured by the pressure analog sensor reaches the regulation pressure • control of load operation as soon as the pressure measured by the analog pressure sensor reaches the minimum regulation pressure (regulation pressure – regulation deviation) • ordering of motor shutdown after the period of no-load operation • inhibiting of motor restart if the pressure in the oil tank is above 1.5 bars (RLR 75 at 220 or automatic restart option).

4) Control of condensate drain-off The frequency and the duration of drain solenoid valve opening can be programmed in order to adapt to the size of the machine and the volume of condensate to be evacuated.

5) Signalling of maintenance operations As soon as a maintenance operation is required, either because the machine has reached a number of hours requiring work, or because a sensor has detected that a threshold has been reached, a yellow light flashes and a message indicating the operation to be executed is displayed. The machine does not stop.

4) Battery replacement

6) Management of operating defects

The battery is used to keep date and time when the power supply is off. Its working life depends upon the length of time the machine is off. We recommend replacing the battery every 4 years. However, should the date and time disappear, change the battery as follows (no other parameter is lost): • Turn the power off • Open the flap at the rear of the PCI07 • Replace the old battery with a new one ref. CR2032 • Close the flap • Reset the date and time

As soon as a fault signal appears, the PCI07 stops the compressor, signals the fault through the red light of the reset key and displays a message allowing the cause of the incident to be quickly located. The 8 last faults occurring on the compressor are kept in the memory and can be displayed by a technician holding the electronic key (See 2.3).

1.2 - Functions 1) Control

7) Programming compressor startup and stopping After programming the timers, the real-time clock on the PCI07 allows automatic starting and stopping of the compressor. The clock which operates when the compressor is deenergized is supplied by a lithium battery with 8 years' service life. The maximum battery service life is 8 years with the compressor energized.

5 keys on the front face of the PCI07 can be used by the operator to control and monitor the compressor:

2) Keys Under-pressure shutdown key (F2) Color: red Symbol: oil tank which empties Pressing the "under-pressure shutdown" key: • when the machine is operating, enables the machine to be stopped while maintaining the air pressure in the internal machine circuit during 2 or 3 minutes in order to: - drain the oil more easily, - carry out a check on the leaktightness of circuits under pressure, • when in the programming or initializing menu, enables validation of selected settings.


Pressing on the O key: • stops the machine. Since the machine only stops after 30 seconds no-load operation minimum, stopping can be time lagged. During the period of time-lagged stopping of the compressor, this can be restarted by pressing on the | key. • when the machine is stopped, enables the display of pressure, temperature and compressor status.

Data scroll key (F4) Color: yellow Symbol: • •

briefly pressing this key allows successive displays of machine status data. pressing on the key for more than 3 seconds generates an input on the programming menu.

3) Display The 2-line, 16 character back-lit liquid crystal display can be used to display status, alarm, fault messages together with operating parameters (pressure, temperature, etc.). On energizing the compressor, an initialising message gives the version of the software displayed (e.g.: EPROM P01PCI21). After initialising, the display of the data and the time is used to detect an eventual disturbance in the memory.

1.5 - Definitions • Alarm

An alarm informs the that a maintenance operation is necessary either because the machine has reached a certain number of hours' operation, or because a sensor has detected a threshold. An alarm does not lead to compressor shutdown. It is indicated visually by the yellow alarm indicator light LED flashing and by a message informing the operator of the nature of the alarm or the operation to be executed.

• Fault

A fault leads to compressor shutdown and is linked to a machine malfunction. It is signalled by the red LED associated with the F3 reset key and by a message informing the operator of the nature of the defect (e.g.: overpressure, temperature fault, etc.).

• Analog sensor

An analog sensor is a sensor which has a continuous measuring range. The PCI07 manages two analogue inputs: one for the pressure sensor (0 to 17 bar), and one for the oil temperature probe (-20 to +151°C).

• Timer

A timer is used to program automatic startup and shutdown of the compressor. Starting and stopping can be programmed for one day of the week, work days (Monday to Friday), week-end or every day of the week. 8 timers can be programmed. Examples: • Timer 1 active for Monday, Start timer 1 = 8 a.m. and stop timer 1 = 4 p.m. Î the compressor will operate on Mondays from 8 a.m. until 4 p.m.. • Timer 5 active for Thursday, Start timer 1 = 6.30 a.m. and stop timer 1 = 8.15 p.m. Î the compressor will operate on Thursdays from 6.30 a.m. until 8.15 p.m..

When a compressor is pending restart by a timer, the message « WARNING AUTO RESTART BY TIMER » moves through the display. If the compressor is pending restart by a timer, the compressor can be forced to start manually by dual pressing on the start key ( I ). This forced operation will not alter the timer settings. Examples : In the examples above, if the key is double pressed before Monday 8.00 a.m. or Thursday 6.30 a.m., the compressor will start and stop automatically on Monday at 4 p. m. or on Thursday at 8.15 p.m..

• Regulation pressure / differential pressure

The regulation pressure is the use pressure from which the compressor will begin operating in a no-load configuration. The differential pressure defines the no-load operating range of the compressor. Load operation restarts when the machine outlet pressure has fallen from the regulation deviation relative to the regulation pressure.

• Remote control

Possibility of starting and stopping the compressor remotely. In all cases, local mode shutdown has priority. If the compressor is stopped remotely, it will be possible to restart it remotely and the ‘stopping’ message will be displayed. If the compressor has been stopped locally, its remote restart will be impossible. The remote start/stop mode has priority over timer operation: - When a compressor is stopped remotely, the « WARNING: REMOTE RESTART » message moves through the display. - If a compressor is started remotely when outside the operating times programmed on the active timers, the « WARNING AUTO RESTART BY TIMER » message moves through the display.

• Remote control option

This option allows the compressor to be started or stopped remotely and a general fault reported (light, siren, etc.). - Operation as main compressor and back-up for 2 compressors (serial cable). - To control and display the status of a remote compressor (serial interface).

• Serial port option

Using an interface, this option allows alternating operation of 2 compressors or all the operating parameters from the compressor to be displayed on the PC.

• Automatic restart

This option enables automatic restart of the compressor after a power outage.

• Max. number of starts authorized per hour

This function is for defining the minimum operating time of the motor between its last startup and automatic shutdown as a result of prolonged no-load operation. If, on a prolonged no-load operation, the motor no-load operating time is exceeded, compressor shutdown will only be authorized if the number of maximum restarts per hour is complied with. Example: - The maximum number of restarts authorized per hour is set at 3, - the motor operating time is 10 minutes. In these conditions, the motor must be capable of operating for 20 minutes minimum before its shutdown is authorized (60/3). If, 5 minutes after restarting the motor, the compressor transfers to no-load operation, motor shutdown will take place 5 minutes after the end of the motor time lag in order to reach the 20 minutes minimum operating time (5+10+5 minutes).

• Stand-by pressure and differential stand-by

Regulation pressure and differential pressure of the stand-by compressor when 2 compressors operate simultany (OPTION).

• Onload operation

The compressor is generating at full load (inlet valve 100% open) or at part load (inlet valve partly open).

• Offload operation

The compressor operates at nil flow and with the oil tank empty.

HIGH PRESSURE FAULT

HIGH TEMPERATURE FAULT

WATER FLOW FAULT

SERIAL INTERFACE FAULT


The HP is tripped after detecting overpressure in tank or the analog pressure sensor at the machine output has reached the safe HP level (max. pressure+1bar) . Compressor stops. Possible cause: • intake chamber valve does not close • Analog pressure sensor fault Restart possible if pressure falls below HP trip value after resetting by pressing on reset key F3. The analog temperature probe measures a temperature at the element outlet which is above the compressor maximum operating temperature (temperature protection). The compressor is stopped. Possible causes: • low oil • ambient temperature too high • obstruction of cooling air age through oil radiators • clogging of oil/water exchanger • obstructed oil circuit • stopped fan • defective temperature probe Restart possible if the temperature has fallen below the maximum safe temperature and after resetting by pressing on reset key F3. This fault is detected when the compressor is onload or offload (water cooling). The fault is displayed after a 6 second confirmation time laps. The compressor stops. Possible causes: • general inlet closed • solenoid valve has not opened • clogging of exchangers • water flow controller defective Restart is possible after having eliminated the fault and after resetting by pressing on reset key F3. The compressor is operating with the serial interface option. The EXTERNAL regulation mode has been selected. The serial interface is not detected by PCI07. The compressor stops. Possible causes: • the communication cable connecting the electronic board to the serial interface has not been connected • the serial interface is not supplied • communication cable fault • serial interface electronic board fault. Restart possible after eliminating the fault and resetting by pressing on the reset key F3.

Chapter 4 - Options The 8-pole connector situated behind the PCI07 is used to connect up the 2 following options: - Serial cable - Serial connection interface In order to connect one of the options, PCI07 has to be set to 'SERIAL CONNECTION OPTION ON' (machine configuration menu).

Alternancy: The operation described previously is reversed every 24 hours or every week based on the selected operating mode. During a permutation, compressor A is regulated according to the main set point and compressor B according to the backup set point. On the next permutation, compressor A regulates according to the backup set point and compressor B according to the main set point.

Timer management:

This option can be used to operate 2 compressors alternately after connecting their PCI07 using the connection cable.

Each compressor operates through its own timers. As soon as one compressor is outside its programmed operating times, the « CAUTION: AUTOMATIC RESTART BY TIMER » message is displayed. The second compressor then operates independently and based on its own settings and its own sensor. The « MAIN » and « BACKUP » display disappears. When both compressors are in their programmed operating times, the main/backup mode is automatically reactivated.

Configuration of the PCI07:

Protection management

To allow alternating operation of 2 compressors, configure the PCI07 of both compressors using the explanatory notice ref. 62 139 391 11.

On a malfunction of one of the two compressors or shutdown under pressure, this transfers to autonomous operation and each one regulates according to its own measured pressure and its own regulation set point. Thus, if a fault appears on one set or if it is stopped by a , the other set is not blocked and transfers onto autonomous operation.

4.1 - Serial cable Alternating operation of 2 compressors (Kit ref.: 62 590 810 00, cable ref.. 62 363 691 00)

Cabling: The PCI07 of the two compressors must be with the option cable by their X6 optional connectors. The shielded cable must be connected to the earth of each PCI. The shielded cable must not be installed near the main supply cables. WARNING : The earth connections of the two machines must be equipotential.

Regulation: When one of the 2 compressors is started by pressing on the | key, this compressor operates separately its own regulation settings and pressure sensor. As soon as two compressors operate simultaneously, the main/backup mode is activated. The pressure sensor used for regulation is then the compressor A sensor. On main/backup dual operation, the following are displayed: - regulating compressor as main compressor: ‘DUTY ONLOAD’ ‘DUTY OFFLOAD' - compressor acting as backup: ‘ST-BY ONLOAD’ ‘ST-BY OFFLOAD’ •

When the pressure exceeds the backup pressure, compressor the backup set transfers onto vacuum operation and is then stopped by its motor time-delay and its number of startups per hour. • When the pressure exceeds the regulation pressure, compressor the main set transfers onto no-load operation and is then stopped in relation to its motor time-delay and its number of starts per hour. • If the pressure falls below the regulation pressure less the regulation deviation, the main compressor transfers onto load operation. • If the pressure falls below the backup pressure less the backup deviation, the backup compressor restarts if it had stopped and transfers onto load operation.

4.2 - Serial interface (Kit ref.: 62 590 879 00, interface ref.: 62 363 784 00) This option is used for remote control and display of compressor status.

Interface description: The bidirectional serial interface continually communicates with the electronics board controlling the compressor. The data are sent from the board to the interface and vice versa via a cable. This option takes the form of a box fixing on DIN rail. The controls and data available on the interface are: - Remote start / stop of the compressor - Load / no-load start of the compressor - Pressure switch type output (load/no-load) - Regulation mode (internal or external) - Compressor start (motor rotation) - Machine availability - General fault reporting If this option is used, it will require selection of the type of regulation in the programming menu: Internal (regulation by the settings given by PCI07 and the internal pressure sensor) - External (use of load/no-load operation input)

Configuration / Cabling: See diagram ref. 62 139 444 00.


Inputs / outputs: (See diagram ref. 62 139 444 00) Inputs: • input 1: remote start / stop This input controls starting and stopping of the compressor. • input 2: load / no-load operation This input can be used to force load or no-load operation of the compressor. The input is activated if the external regulation mode is selected in the programming menu. Outputs: • output 1: unused • output 2: compressor internal regulation status Pressure switch type output reflecting the compressor theoretical operating mode (load or no load) relative to the regulation instructions set on PCI07. Active output when operating with load. • output 3: local / remote regulation This output reflects the regulation mode configured on PCI07 (internal or external regulation). With internal regulation, the compressor uses its own settings and internal pressure sensor to regulate operation. In external regulation, input 2 is used for the load or no-load start order. Active output in external regulation. • output 4: load operation Active output when the compressor motor is rotating • output 5: availability Active output when the compressor is ready to operate (no fault, machine energized and start pressed) • output 6: general fault Active output when no fault. On a break of the communication cable connecting PCI07 and the interface, the outputs are inactive (open). If PCI07 is configured for external regulation, this changes to fault.

Chapter 5 - Temperature protection test The temperature protection trip of a compressor can be tested. This test has to be carried out once every year in order to check that this protection operates properly.

Test procedure: • • •

Set the compressor to shut down, and energize. When the temperature measured by the analog sensor exceeds 60 °C, place the cursor in the programming menu (press on key F4 longer than 3 seconds). In the programming menu, press on keys Ο and | simultaneously. The « TEMPERATURE SYSTEM TEST » message comes on.

When the « TEMPERATURE SYSTEM TEST » message is displayed, the compressor is ready to carry out a temperature protection trip test. For this test, the maximum operating temperature setting is less than 60 °C in order to cause tripping of a protection in the normal conditions of operation. • • • •

Set the compressor to On by pressing on key |. Wait for the temperature protection to trip. Check that this trip takes place at 60 °C. After tripping the protection, the « SENSOR OK » message is displayed. The fault indicator is on. The test is valid. Eliminate the fault by pressing on the reset key F3.

After eliminating the fault, the maximum temperature setting automatically adopts its initial value. The compressor is able to operate normally .
