2.3 – ANALOG INPUTS AND OUTPUTS
Note: All the analog input devices have functions to detect faults of open-circuit, short circuit, and out of range.

Entrada analógica 1:tipo 4-20mA fixa.
Entradas analógicas 2 e 3: a Control II usa módulos que permitem que diferentes tipos de sensores e sinais sejam utilizados;
o hardware correto deve ser ajustado a cada tipo de sensor.

Analog output 1:
Standard: 4-20mA signal, selectable function
Active variable speed control:
4-20mA Signal to frequency inverter; 4mA = minimum speed; 20mA = maximum speed.
The drive is activated and stopped by the output to relay R1; drive fault detection at digital input C4.
DIAGRAM OF MACHINE STATUS
The interface operational logic is presented in the diagram of machine status. The status block determines the functionality of the control
at each moment. The control can only be in one status at each moment. The control will move from one status to another according to the
defined input and output conditions of each block, and the defined connections between status blocks.
Definitions:
Fault: Is a detected abnormal condition that must be signaled to the operator and might require an automatic safety action, depending on
type and fault definition.
Start-up Fault(S): A start-up impediment fault is a condition that might represent danger or cause damage to the compressor if it starts while
the condition is present. Start-up impediment faults are only triggered when trying to start a motor in the "ready to start" condition. Interface
start-up impediment faults are not triggered during an automatic motor start-up sequence from standby condition. The interface start-up
impediment faults reset themselves. An interface start-up impediment fault code is shown when it is activated, but it is not recorded in the
faults register file.
Operation Impediment Fault (R): An operation impediment fault is a condition that might represent danger or cause damage to the compres-
sor if it starts while the condition is present. The operation impediment faults are only triggered if a motor start-up sequence is initiated. The
operation impediment faults reset themselves and do not prevent the compressor from going to start-up condition. An operation impediment
will keep the compressor in standby mode and allow the motor start-up when the condition is no longer present. A fault code is shown when
the fault occurs, but it will not be recorded in the faults register file.
Fault Alarm (A): A fault alarm is a warning of a condition that does not represent immediate danger or a potential risk to the compressor.
An alarm status will not shut down the compressor or affect its normal operation. A fault alarm code is shown, and must be reset manually
once the condition is solved or no longer exists.
Shut down fault (E): A shutdown fault is a condition that might represent danger or potential damage to the compressor, if the condition per-
sists. A shutdown fault will cause the interface to stop the compressor. A shutdown fault code is shown, and must be reset manually once
the condition is solved or no longer exists. Two types of shutdown faults are defined: a) Nonemergency shutdown, an immediate controlled
stop is performed; b) emergency shutdown, an instant shutdown is performed.
