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 descripti on 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 analog inputs: a temperature probe probe and • a pressure sensor Programming of compressor start-up and shutdown • Control, fault reporting and 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 fi tted 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 Signallin g 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 replacement

6) Management Management of operating 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

7) Programming Programming compressor startup 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

•

•

Alarm An alarm informs the user 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.

•

Remote control

Automatic restart restart

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.  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.  the compressor will operate on Thursdays Thursdays from 6.30 a.m. until 8.15 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

•

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 i s 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.

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 display the status of a remote compressor (serial interface).

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.

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

3.5 - Faults SHORT CIRCUIT IN TEMPERATURE

Compressor stopped. Possible causes:













HIGH PRESSURE FAULT

HIGH TEMPERATURE FAULT

WATER FLOW 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 passage 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 •













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 user, 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:













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 m ode 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)

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.
