2 GENERAL
2.1 FST-110
The High Voltage FST-110, FST-110, is intended for testing of dielectric withstand voltage at
the specified voltage. The FST-110 measures the leakage current cause by the voltage and
isolation. The current limit is user adjustable between 0 to 100mA.
ANY UNAUTHORIZED OPEING OF THE EQUIPMENT WILL VOID THE WARRANTY.
2.2 FST-110 control modes
The FST-110 can be controlled either locally by means of the front panel buttons, indicators
and analogue meter or in automatic test systems by a computer. Other remote control possibilities exist by using the D25 connector in the back panel.
2.3 Calibration
The FST-110 is factory tested and calibrated to meet the accuracy requirements. We recommend to calibrate FST-110 regularly once a year. The equipment may be calibrated in our
factory or by other means agreed separately. There is a replaceable measurement module,
which can be sent to calibration.

3 SAFETY PRECAUTIONS
3.1 General
The operator should study carefully the instruction manuals and operation of the FST-110 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-110
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-110 is high enough to cause convulsion and potentially to get
trapped to the parts under high voltage. The FST-110 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-110 IS
SWITCHED ON!

------------------------------------------------------------------
4 INSTALLATION
4.1 General
FST-110’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-110 is
not allowed to be carried from the front panel handles. For carrying FST-110 the handles on
the side of the equipment should be used.
The FST-110 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-110, 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-110 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-110 wiring diagram. When the safety
circuit is open the “Fail” –indicator is flashing, if trying start testing. See back panel figure.
The FST-110 internal safety circuit is not an approved safety relay system! The safety circuit
of FST-110 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-110 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-110.
4.5 Mains supply and Switching On the FST-110
Connect the FST-110 to the mains supply in following order:
- Check that the position of the front panel POWER switch is 0.
- Connect the control and high voltage cables to the FST-110.
- Plug the mains cord to the FST-110.
- Plug the mains cord to a mains outlet
- Switch ON the FST-110

5.6.1 Timer
There is timer for semiautomatic testing. Timer stops testing automatically when setting time
has been reached. It is possible stops test by “stop”-button. In Timer off –mode test is ON until
the “Stop”-button is pressed (however max 120s).
5.6.2 Spark detector (SPdet)
It is possible that during the dielectric withstand test some partial discharge caused sparks
may occur. The FST-110 has special detector for this situation. Detector sensitivity must be
checked and adjusted every time when test parameters or type of device under test and
ambient conditions are changed. The sensitivity is higher with value 1 and lower at value 99.
If there are high capacitance in device under test, detector can make fail without reason. The
detector may cause a test fail if for instance a large capacitance connected to the test circuit.
This may occur especially with fast ramp up times in connection with capacitance.

5.6.3 AC/DC Output
Standard FST-110 has an AC output voltage and optionally available DC output.
The DC option has a full wave rectifier and 5nF filter capacitance. The equipment also has an
automatic discharge resistor (4,5M / 1,5W ) if the DC option is used. The user should be
aware that if the D.U.T. capacitance and test voltage are very high, voltage might still be
on a dangerous level even the FST unit has been switched off.
5.6.4 Voltage Ramp
There are two different methods to impose the high voltage on the D.U.T.
Press the TEST On and start increasing output test voltage gradually by changing the set value
of the voltage (Parameter setting mode).
In automatic ramp up and ramp down mode the voltage ramp up time and ramp down time is
set in the parameter RAMP. Test time starts when voltage is up.
5.7 Testing
The test voltage is switched on by pressing the “Start” -button. The recommended minimum
measurement time is at least 1 second. The leakage current and other information can be seen
on the display:
Test voltage is switched off by pressing “Stop” –button (if there is timer used, then according
to timer setting)
After that the measurement can start again with “Start”-button or return to “Ready” –display
by pressing “Stop” –button.

7 OPERATION WITH COMPUTER
7.1 General
The FST-110 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 equipment is delivered standard with RS485 interface. By using this interface all
FST-line equipment can communicate with each other.
7.2 Connections
The RS485 connection to other FST-110 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.

This means a possibility to incorporate the FST-110 in less sophisticated automatic test
systems. The FST-110 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-110 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. It also has two additional programmable outputs.
“Test On” output is on, when voltage is on.
“Fail” output is 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. It also has two additional
programmable inputs.
“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 is not connected.
Please see the main circuit diagram for these connections.
