2 Safety Warning
During operation, parts of the FT 3000 are under dangerous voltages. The units conform to protection class 1 and
require an earth connection on the corresponding module connector and/or terminal on the 19" rack.
The units have been designed and tested in accordance with IEC 348 and have left the factory in perfect condition.
These operating instructions include information and guidance on the safe operation of the equipment and installation.
Please specially note section 6.
If in doubt about the condition of any part following electrical, environmental or mechanical damage, the unit should be
returned for repair.
3 Applications
FT 3000 tachometers are used to monitor and measure frequencies in the range 0 to 30000Hz eg from frequency
proportional sources such as rotational speed.
The FT 3000 family comprises of the following modules:
•Monitoring module (Motherboard) FTFU 3024
with input card -E01 FTFU 3024- E01 Art. Nr. 377Z-03981
with input card -E02 FTFU 3024- E02 Art. Nr. 377Z-03982
with input card -E03 FTFU 3024- E03 Art. Nr. 377Z-03983
•Trip Chain Control card FTBU 3034 Art. Nr. 377Z-05030
•Frequency to current converter FTW 3013 Art.Nr.377Z-03984
(Auxiliary module)
•Relay card (Auxiliary module) FTV 3090 Art. Nr. 377Z-03985
•Comms module FTK 3072 Art. Nr. 377Z-03986
•PSU 116/230Vac FTZ 3061 Art. Nr. 377Z-04065
•PSU 24/48Vac FTZ 3062 Art. Nr. 377Z-04073
•PSU 14...70Vdc FTZ 3064 Art. Nr. 377Z-04074
•PSU 75...372Vdc FTZ 3065 Art. Nr. 377Z-04075
•Mains filter (2 wire) FTZ 3069 Art. Nr. 804D-35886
FT 3000 3 channel speed monitoring and over speed protection systems comprise of 3 independent channels, from
speed pick ups through to limit signalling. High integrity operation is provided for in the rack through the use of 2
redundant power supplies to each module via diode decoupling. Rack module supply requirements are matched to the
incoming supply by the 2 redundant power supplies.
4 Construction
The modules are plug in units in a 19" rack, with height 3 HE and with 4, 12 or 20 TE in accordance with DIN 41494.
Compatible card frames with up to 21 locations at 4 TE are used for mounting and wiring the modules. The card frames
are built by JAQUET to customer requirements. Connections for speed sensors, control and output signals along with
power supplies are normally provided at the back via screw terminals or Termi-Point connections.The setting of
measuring range, monitoring and relay parameters is via front panel RS 232 interface on the FTK 3072 comms module
to a PC. This module controls the data flow between the PC and individual modules in the rack (RS 485 rack bus). The
parameters are stored in EEPROM’s and protected against mains failure.
