6 Programming and configuring the FCM*
6.1 Standard configuration
The FCM controls are supplied with the following default settings:
FCM00NTC00:
• NTC probes (range: -40°C÷100°C);
• display in degrees °C.
FCM0001000:
• temperature probes with 0÷10 V voltage output;
• range: -40°C ÷100°C;
• display in degrees °C.
FCM0002000:
• pressure probes with 4÷20mA current output;
• range: 0÷30 bar;
• unspecified refrigerant;
• display in bar.
The following configuration is valid for all models:
• “DIRECT” operating mode;
• use of probe 1 only;
• probe input 'filter' with time constant=1 second;
• set-point with min. value;
• operating range of the output 0÷10V: from 0% to 100%;
• soft-start at 2 seconds;
• cut-off at 0;
• speed-up disabled;
• combined action disabled;
• High and Low alarms disabled;
• digital inputs not used;
• digital output not used;
• display of the unit of measure;
• normally displayed value: measurement of probe 1;
• keypad and remote control enabled.
6.2 Initialisation of FCM* instruments
When programming the FCM* controller, follow these instructions carefully:
• first select the operating mode (parameter C00), as some parameters are normally hidden and are only accessible in particular
operating modes;
• select the type of probe used (if different from the default type) (C13 parameter), the type of refrigerant used (if necessary, param.
C14), and the minimum and maximum values of the probes (parameters C15 and C16);
• configure inputs and outputs (parameters C19, C29, C30, C31);
• set the remaining C parameters (configuration parameters);
• set the P parameters (frequently-used parameters);
• set the set-point.
OPERATING MODE. The operating mode is set by parameter C00.
C00=0 ÜÜ slave-direct operation. In SLAVE-DIRECT operation, the 0÷10V output of the control is directly proportional to the value of
probe 1. the minimum value of the probe (0V or 0mA or 4mA) corresponds to the minimum value of the output (param. C04);
the maximum value of the probe (10V or 20mA) corresponds to the maximum value of the output (param. C05).
In this operating mode not all parameters will be available. This operating mode is not available in model FCM00NTC00.
C00=1 ÜÜ slave-reverse operation. In SLAVE-REVERSE operation, the 0÷10V output of the control is inversely proportional to the
value of probe 1. The minimum value of the probe (0V or 0mA or 4mA) corresponds to the maximum value of the output (param. C05);
the maximum value of the probe (10V or 20mA) corresponds to the minimum value of the output (param. C04).
In this operating mode not all parameters will be available. This operating mode is not available in model FCM00NTC00.
C00=2 ÜÜ DIRECT operation. In DIRECT operation, the 0÷10V output of the controller increases as the values measured by the probes
increase, depending on the set-point (param. St1) and on the other control parameters.
C00=3 ÜÜ REVERSE operation. In REVERSE operation, the 0÷10V output decreases as the values measured by the probes increase,
depending on the set-point (param. St1) and on the other control parameters.
C00=4 ÜÜ DIRECT/REVERSE mode through digital input. This operating mode depends on the status of the digital input ID1:
ID1 not active (open) Ü DIRECT operation with main set-point and differential (St1 and P01);
ID1 active (closed) Ü REVERSE operation with main set-point and differential (St1 and P01);.
