L’allarme interviene anche con compressore fermo e/o unità in "Stand-by".

Viene fermato solo il compressore 2.

Remotizzazione allarme con contatto pulito su scheda Board B uscita C6.

Ripristino automatico (primo intervento).

Ripristino manuale (secondo intervento in 15 minuti).

AL18 - Alta Pressione Compressore 2 (sonda) Scheda Board B ingresso analogico B 6 (con "High pressure probe present = Y").

L’allarme interviene quando il valore rilevato dalla sonda di pressione (Hi press. 2) supera il set impostato nel parame- tro "Maximum Pressure Value".

Viene fermato il compressore 2.

Remotizzazione allarme con contatto pulito su scheda Board B uscita C6.

Ripristino Manuale.

AL19 - Alta Pressione Compressore 2 (pressostato) AL19 - Termico ventilatore condensatore

Scheda Board B ingresso ID 2. (Configurazione 2 Com- pressori con 2 circuiti)

L’allarme interviene immediatamente all’apertura del con- tatto.

Viene fermato il compressore 2.

Viene posto a 0V il segnale di uscita proporzionale per il controllo di condensazione Y1 (Board B). Remotizzazione allarme con contatto pulito su scheda Board B uscita C6.

Ripristino Manuale.

Alarm remotization with voltage free contact on Board B, output C8.

If the “Hi/Lo Humidity Alarm delay time” set is preset to 0, the alarm is deactivated.

Automatic reset .

AL 15 – External Alarm 1

Board B, input ID 8.

The alarm is available and is activated starting from the opening of the relative input.

The alarm is only signalled. Automatic reset.

AL 16 – External Alarm 2

Board B, input ID 9.

The alarm is available and is activated starting from the opening of the relative input.

The alarm is only signalled. Automatic reset .

AL 17 – Compressor 2 Thermal Relay

Board A, input ID 7 (Configuration: 2 Compressors with 1 circuit).

Board B, input ID 1 (Configuration: 2 Compressors with 2 circuits).

The alarm stops compressor 2, waiting for the natural reset of the thermal relay; then, the compressor is restarted.

If the thermal relay is activated again, within 15 minutes, the compressor is locked and, also after reset, it is necessary to intervene and to perform a reset from the keyboard.

The alarm is activated also when the compressor is stopped and/or the unit is in standby.

Only Compressor 2 is stopped.

Alarm remotization with voltage free contact on Board B, output C6.

Automatic reset (first activation).

Manual reset (second activation in 15 minutes).

AL 18 – Compressor 2 High Pressure (probe)

Board B, analog input B6 (with "High pressure probe present = Y").

The alarm is activated when the value measured by the pressure probe (Hi press. 2) exceeds the set of the "Maxi- mum Pressure Value" parameter.

Compressor 2 is stopped.

Alarm remotization with voltage free contact on Board B, output C6.

Manual reset .

AL 19 - Compressor 2 High Pressure (pressure switch) AL 19 – Condenser Fan Thermal Relay

Board B, input ID 2 (Configuration: 2 Compressors with 2 circuits).

The alarm is activated just after the contact opening. Compressor 2 is stopped.

The proportional output signal Y1, for the condensing control, is set to 0V (Board B).

Alarm remotization with voltage free contact on Board B, output C6.
