3 SAFETY PRECAUTIONS
3.1 General
The operator should study carefully the instruction manuals and operation of the FST-120 as
well as testing instructions for the product to be tested before starting any tests. As a further
safety precaution the operator should be aware of emergency first aid actions. The FST-120
shall only be used strictly according to this user manual. All modifications are not allowed.
3.2 High voltage WARNING
The high voltage connectors in rear panel have a dangerous high voltage during the test.
The current supplied by the FST-120 is high enough to cause convulsion and potentially to get
trapped to the parts under high voltage. The FST-120 measures the current in the circuit and
shall switch the voltage off if the current exceeds the set current limit, THIS FEATURE
CANNOT BE USED AS A SAFETY MEASURE!
NEVER TOUCH THE HIGH VOLTAGE CONNECTORS OR TEST LEADS IF THE FST-120 IS
SWITCHED ON!

4 INSTALLATION
4.1 General
FST-120’s depth is about 370mm and connectors need about 150mm space from rear. The
handles mounted on the front panel are elevated about 40mm from the panel. The FST-120 is
not allowed to be carried from the front panel handles. For carrying FST-120 the handles on
the side of the equipment should be used.
The FST-120 can be used in its own case only in dry and clean environment. The ventilation,
however, should not be prevented.
4.2 Mounting into 19” Module –Rack or Case
When installed into a rack or a similar case it is mandatory to use mounting rails due to the
weight of the device. The holes in the front panel are intended for locking the device in its
place not for backing the whole device. If there are legs below of FST-120, they must take off
before installation to 19” rack. Care must be taken of the air circulation in the rack in order to
avoid temperature rise above +35 °C.
Here are some examples of how build the support for rack installation.

------------------------------------------------------------------
4.3 High voltage connectors
There are three high voltage sockets in back panel. High voltage outputs are two connectors
in rear side. The connections are made according to the below figure.
“Shield” –connection can be used for protection against electrical noise. Connected shield
(assuming that shielded cable is used) reduces measurement errors, which can be caused by
cables, line noise or some other leakage currents. If you suspect measurement errors, use
shielded cable and connect shield to the respective place in the unit. The shield of the LOWER
connector must be connected to the SHIELD- connector at the back panel. Cables and connectors must be specified to high voltage use. Please check with the manufacturer!
See the below picture for connection recommendations.

------------------------------------------------------------------
4.4 External Safety Circuit, Emergency Switches
The FST-120 provides an external safety circuit; which prevents connection of the test voltage, when external safety circuits are open. The safety circuit connector is a part of the external D25 connector. The wiring diagram is shown in FST-120 wiring diagram. When the safety
circuit is open the “Fail” –indicator is flashing, if trying start testing. See back panel figure.
The FST-120 internal safety circuit is not an approved safety relay system! The safety circuit
of FST-120 is designed for indication that for instance doors and test covers are closed or
respectively open. The safety device shall have potential free contact “open” when activated.
The safety circuit can be wired by signal cable; the voltage is about 25 V. To take the safety
circuit in use a jumper J1 (Safety) has to be removed. Location of the jumper J1 are in connection board inside FST-120 near back edge. The jumper is removed by lifting and can be stored
by pressing it to one of the pins. Cables to external control lines are recommend to be kept
short or use relays near FST-120.

-----------------------------------------------------------------5.6.2 Integration time (Integr)
Tester takes measurements and calculates resistance values. Integration time means measurement time, during A/D-converter takes samples. Units are NPLC, it means “number of
power line cycles”, and as an example setting of 100 equates to 2 seconds. A higher integration time value results in a better measurement accuracy, but at same test times sampling
time gets longer. Test time starts when voltage is at the set value.
5.6.3 Ramp up time (Ramp L)
Test voltage ramp up time. Voltage goes from 0 to set value with the user preset ramp up
time.
5.6.4 Use of timer (Timer)
FST-120 has a programmable timer for semiautomatic testing. Timer stops testing automatically when preset time is elapsed. It is still possible to interrupt the test by pressing “stop”button. This will however result in a “fail”-alarm and “interrupted” text in display. In Timer off
–mode test is ON when pressed “Stop”-button (however never exceeding 120s).
5.7 Testing
The test voltage is switched on by pressing the “Start” -button. The minimum measurement
time is recommended at least 1 second.
Test voltage switched off by pressing “Stop” –button (if timer used, then according to timer
setting)
After that the measurement can start again with the “Start”-button or return to “Ready” –
display by pressing “Stop” –button.

7 OPERATION WITH COMPUTER
7.1 General
The FST-120 can be incorporated in an automatic test system providing automatic control
and recording of the test results and other applications. Almost all operations are controlled
by the computer or easier by using a Finero’s specific proprietary application program
Safetest. The command list for computer operation mode is appendix of this manual. The
control interface, like USB, GPIB, RS232 or Ethernet, is optional and it must be ordered separately factory installed. All FST-line equipments are delivered standard with RS485 interface.
By using this interface all FST-line equipments can communicate with each other.
7.2 Connections
The RS485 connection to other FST-120 must be done by a shielded Cat5 cable (STP) RJ45 (8
pin connector).
Other computer interfaces like USB, GPIB, RS232 and Ethernet, are connected with commercially available and compatible cables. The cables are not part of the delivery scope.

8 REMOTE CONTROL AND LOGIC OPERATION
8.1 General
This means a possibility to incorporate the FST-120 in less sophisticated automatic test
systems. The FST-120 operates as in the manual mode but has a provision for extra output
contacts for indicators and logic inputs for the control buttons.
8.2 Start-up
Basically the FST-120 will be put into operation as in manual mode. In addition the wiring of
the operator connector at the rear is to be done. The connector is a 25-pin D-type female
connector. In the main circuit diagram connections of the D25 connector are explained.
Maximum output from +25V are 300mA (7,5W).
8.3 Logic Connections
Contacts are available to show state of test and test result. Also there are two extra outputs,
which are possible programmed.
“Test On” output are on, when voltage is on.
“Fail” output are on, when test current is higher than limit value. At the same time the test is
interrupted.
The connector has logic inputs like the start and stop buttons. Also there are two extra inputs,
which are possible programmed.
“Start” signal switches the test voltage on.
“Stop” signal disconnects the test voltage.
The connector has inputs for the safety circuit, if circuit is open high voltage are not connected.

11 FAULT FINDING

No indicator is lit


Check the power cord connectors are
properly plugged at both ends
Check the voltage in the mains socket.
Check the main fuses (F1 and F2) of
the FST-120. The fuses are located in
the fuse box below the power cord
connector. Check the fuse by a multimeter for conductivity and replace
with the similar one if necessary.
Indicators are lit but buttons don't func- 
tion

Check the safety circuit
Check set values in “Setting” menu.
FST-120 functions but high voltage is 
missing or voltage output is wrong
Possibly the temperature switch
inside the unit transformer has caused the
equipment to stop
Wait for a moment and try again
If the occurs several times please
contact Finero Service


If the above remedies do not remove the problem, please contact the Finero Service or Finero
authorized service point.
