Important
To be read, and understood, in conjunction with the FTC – FasTrak Compact
Instruction Manual 4049.

Figure 1 – example of label
Positioners series FTC-Ixxxxxx are designed to “pilot” and control the position of a valve on which they are
mounted; they receive an “intrinsically safe” analogue input signal 4-20 mA (SETPOINT), which is also an
info about the required position of the valve. Then, it controls the position of the valve through an internal
sensor (potentiometer connected to a rotating shaft): the result is elaborated by the μP, which activates an
I/P converter, to modulate air or nitrogen [or, in specific conditions, natural gas (CH4)] sent to the chamber(s)
connected to the actuator.
As an additional (optional) function, the FTC-Ixxxxxx may modulate a passive 4-20 mA analogue signal
(FEEDBACK), to indicate the current position of the valve. From the Intrinsic Safety point of view, the 2
circuits are totally independent.
Configuration and diagnostic of the device is possible by the integrated local interface (display & keyboard)
or using the HART capability. Additionally, it is possible to have the benefit of high speed connection using
the ‘FTx positioner connection cable’ on port X4.
Warning
X4 connection facilities is restricted to use in a non-hazardous area following the
below 2 indication:
- Only the ‘FTx positioner connection cable’ can be used.

- The laptop used must be powered from battery or by a power supply unit in
compliance with IEC 60950-1 with Maximum Output Voltage (Um) ≤ 30V.
Warning
In case of “minimum ambient temperature” below -40°C, the optional FEEDBACK
cannot be connected and the jumpers on the PCB FTCompact-PW, for internal
circuit connection, must be removed by the User.
Figure 2 – FTC-I electric circuit
Warning
Highlighted in the red circle are the jumpers (JP1, JP2 and JP3) that must be
removed to exclude the feedback circuit when the minimum temperature can be
below -40°C.
Important
Positioners series FTC-Ixxxxxx are designed and certified in conformity to the
European Directive 2014/34/EU, and according to the International IECEx Scheme.
The Positioners shall be connected to 1 or 2 [Ex ia] or [Ex ib] Associated Apparatus (Diode Safety Barrier or
Galvanic Isolator), in compliance with the maximum voltage (Ui), current (Ii) and power (Pi) values stated in
the label (see "Rated characteristics"). In both cases the Positioner can be installed in Zone 1 (or Zone 2),
but when the whole system has "ib" protection level, the Positioner shall not be used to modulate natural gas
(CH4). In case the system has "ic" protection level, the Positioner may be installed only in Zone 2 and, of
course, it cannot be used to modulate natural gas (CH4).
The Positioner shall be installed in compliance with EN IEC 60079-14 Standard (current Issue) and any
inspection maintenance shall be carried out following the provisions of EN IEC 60079-17 Standard (current
Issue); all Intrinsically Safe circuits shall be included in Descriptive System Documents (EN IEC 60079-14,
art. 4.2 and EN IEC 60079-25, art. 4).

3 COMMISSIONING
1. Before commissioning a safe electrical equipment, in a system or plant, the user shall check its
compliance with the design data and its correct installation. An Initial Inspection shall be carried out
by suitably qualified personnel, according to the requirements of the Standard EN IEC 60079-17
(current Issue).
2. Verify that any special conditions for safe use, detailed on the EU Type Examination Certificate or
on the IECEx Certificate of Conformity, are complied with, paying special attention to the installation
conditions, if any.
3. Check that the Positioner supplied is suitable for the specific hazardous area classification (Zone 1
or Zone 2, gas group IIA, IIB, or IIC, according to the System Protection Level).
Warning
The Device is NOT suitable neither for zone 0 nor for Locations with Combustible
Dusts.
4. Verify that the temperature class, marked on the Positioner, is correct for the area classification,
according to the actual ambient temperature.
5. Check that the Positioner is connected to the Associated Apparatus (1 per channel) provided for in
the corresponding Descriptive System Document.

4 MAINTENANCE
Warning The following instructions must be respected:
1. Maintenance shall be carried out by suitably qualified personnel only, trained in
the specific features of the equipment, and on the Intrinsic Safety technique, in
compliance with the provisions of the Standard EN IEC 60079-19 (current Issue).
The replacement of any part of the Positioner series FTC-I shall be done only
with original parts supplied by STI S.r.l.
2. Periodic Inspections shall be carried out, by suitably qualified personnel, in
compliance with the provisions of the Standard EN IEC 60079-17 (current Issue).
3. The replacement of any part of the Positioner series FTC-I shall be done with
original parts supplied by STI S.r.l.
4. The use of Positioners that have undergone work not authorized by STI S.r.l.
absolves
STI S.r.l.
from all liability and invalidates the relative warranty.
