Get out with a percorso.
A single hub to connect symptom, circuit, component, manufacturer, manual and equipment. Thinked for the technician who must quickly understand where to look and how to continue.

Six entrances.
The same answer ordered.
We do not force the technician to know the structure of the site: can start from the symptom, component, plant, brand or document it has in hand.
01 / SOSI have a fault
100 answers: symptoms, first controls and path of diagnosis.
Open 100 responses → 02 / PARTI look for a componentFunction, selection, documents and Tools & equipment.
Open the routes → 03 / SYSWork on a plantBank, cell, central, chiller or process.
Choose the application → 04 / OEMI look for a manufacturerOfficial website, families, documents and support.
Open the directory → 05 / PDFI need a manualBrand, model, language, revision and official source.
Enter Manual library → 06 / TOOLI look for a toolFrom work to the relevant professional category.
Go to Tools & equipment →Guided diagnostics
The symptom is the beginning,
not the conclusion.
These cards do not replace a diagnosis on the field: organize the first data to collect and lead to the correct sources and tools.
Open the 100 RESPONSE →Search by symptom, component or alarm code.
SINTOMOPRIMI RISCONTRICONTINUARY WITH
02High pressureCondensation outside the field
Air/water flow, cleaning, fans, room temperature, charge, presence of non-condensables and calibration.
03Low pressureReduced evaporation power supply
Thermal load, airflow, frost, valve, filter, charge, oil return and control settings.
04Compressor not partCheck, protection or circuit
Request for gear, power supply, protections, switches, thermal, winding, Drives and reboot conditions.
05_ Ineffective frostice or irregular repair
temperature probe evaporator, resistors or hot gas, duration/end sfrost, drainage, fans and infiltrations.
06Loss of refrigerantSearch and confirmation of the estate
Historic load, joints, oil traces, compatible search method, leak-tightness test and qualified repair.
07Check alarmCode without operating context
Brand, model, full code, I/O status, probes, historical events, software review and link scheme.
SECURITY / COMPETENCE
Controls on refrigerants, pressure parts and electrical equipment are intended for qualified personnel. Before the intervention apply manual of the manufacturer, business procedures and regulations in force.
