6 ADJUSTMENTS
6.1 Configuration of the machine
Using a wizard (Constructor menu), it is possible to configure the machine with help. The first choice involves
the number of circuits (1 or 2) through the parameter PG01; in the case of a bi-circuit, the choice of
condensation type, either singular or separate (PG30), becomes important as does the presence or absence of
expansion (PG02). These 3 parameters define the type of machine and the hardware that supports it, as is shown
in the following table.

(*) Note: Temperature is transformed into pressure by selecting the type of cooling (coolant) gas that is used
(parameter PH31).
Using the same wizard, the number of compressors and fans for each circuit are also set, as is the presence of
the inverter for the compressors and fans, the number of throttlings and safety measures for the compressors
and the activation of the fans. A check will verify whether the necessary hardware resources for the machine
type are sufficient or not, generating an eventual AH01 hardware configuration alarm.
Note: Enabling the inverter for the adjustment of the compressors, the FIRST compressor will be the one
controlled by the inverter, while any other subsequent compressors will be sealed (without throttlings) and will
be controlled by digital relay output.
Similarly, enabling the inverter for the adjustment of the fans, the FIRST fan will be the one controlled by the
inverter, while any other subsequent fan with be controlled by digital relay output.
For each inverter it must be configured the position of the device activation consent digital outputs.
