1.2 INSTALLATION AND STA T UP
1.2.1 INSTALLATION P OCEDU E
The installation procedure consists of the following steps:
•Unpacking the equipment;
•Selecting the site where the equipment will be used;
•Connecting the Heat Station (if remote Heat Station is provided);
•Connecting accessories or interfacing the system with other controls (if necessary);
•Completing the Power and Ground/Earth connections.
POWER AND GROUND/EARTH CONNECTIONS MUST BE MADE LAST. FAILURE TO DO SO WILL
CREATE A HAZARDOUS CONDITION THAT MA RESULT IN EQUIPMENT DAMAGE, PERSONAL
INJUR , OR DEATH.
NOTE: Ultraflex has a staff of field engineers who are available to supervise the installation of the equipment. If
installation service is required, contact our Technical Service Department for additional information.
Provisions for facility electrical power service are customer furnished. Requesting field engineering assistance before

1.2.2 UNPACKING AND INSPECTION
This equipment has been thoroughly inspected and tested prior to packing and is ready for operation. After careful
unpacking, visually inspect for shipping damage BEFORE attempting to operate. If any indication of damage is found,
file an immediate claim with the responsible transport service and advise your sales representative.
INSPECT EQUIPMENT BEFORE INSTALLING. DAMAGED EQUIPMENT MA RESULT IN IMPROPER
OPERATION AND CREATE A HAZARDOUS CONDITION RESULTING IN PERSONAL INJUR OR
DEATH.
THE CARRIER IS RESPONSIBLE FOR ALL DAMAGE CAUSED IN SHIPMENT INCLUDING CONCEALED
DAMAGE.
1.2.3 SELECTING THE DEVICE SITE
Consider the following when choosing a location for the device:
•Make sure the system is installed in a debris free zone;
•The device has to be connected to a power source;
•Make sure the device is easily accessible by the operator;
•evice has to be seated on a mechanically secure surface;
1.2.4 COOLING EQUI EMENTS
The power transistors and rectifiers in the Power Supply are maintained within their safe operating temperature
range by means of forced air cooling (fans). The fan inlets must be kept clean from obstructions in order to insure
proper air circulation. If installed in confined spaces, care must be taken that the ambient temperature (the
temperature of the space immediately surrounding the Power Supply, does not rise above the limit specified as 40°C.
Periodic cleaning of the Power Supply exterior is recommended.
1.2.5 AC INPUT CONNECTION
The Power supply connects to the power network through a 6 ft (1.80m), power cord (supplied). Additional fuse or
circuit breaker and residual current circuit breaker on that power branch is a good choice since it will provide extra
protection in addition to the unit’s internal protection. A mechanical switch is also recommended within the
operator‘s range and vision and possibly closer to the Power Supply.
Only trained personnel should open the unit cover and operate the breakers.

NOTE: LOCAL CODES MA HAVE STRINGENT REQUIREMENTS. IT IS THE CUSTOMER‘S
RESPONSIBILIT TO BE FAMILIAR WITH AND TO COMPL WITH ALL APPLICABLE CODES
CONCERNING CONDUCTOR RATINGS AND WIRING PROCEDURES. AN ELECTRICIAN FAMILIAR
WITH THE LOCAL REGULATIONS SHOULD DETERMINE PROPER WIRING CONNECTIONS.
1.2.6 STA T-UP
1. Connect the AC and ground connections as described in Section 1.2.5;
2. Turn the Power Switch on to power the system. Check for any Fault or Alarm messages. If the status screen
shows “100% Power” message, then the system is ready for operation.
See Section 2 of this Manual fo Connections Diag ams.
1.2.7 USING THE MACHINE
1. Connect the machine to the electric supply 220/230 VAC – single phase;
2. Crucible. Check that your crucible is good enough to make a melting. A too much used crucible can make the
casting very slow. Check also that the bottom is not too thin, you risk that it brakes during the melting causing the
metal going out.
3. Place the crucible in the melting chamber. The purpose of the thermocouple is to read the temperature of the
induction coil in order to protect it from overheating.
4. Switch on the machine pressing the main switch (fig. 2.2-2) positioned on the back of the machine;
5. On the control panel you have the possibility to adjust 2 parameters:
- Power. This parameter determines how fast the melting will be done. We suggest to use 100 % power;
- Time. This timer can be set in 2 states – OFF or time in minutes 1 – 30. If the time is set (1 – 30 min) after starting
melting cycle, the timer will start to count down. When the set time expires, melting cycle stops. The purpose of this
timer is “time out“ for heat on. If you do not like to use the timer, set it in “OFF” state.

6. Choice of parameters. In order to choose the parameter, push the “SELECT” (fig. 2.3-10) button. The
corresponding red LE (fig. 2.3-6, 7, 8) will flash and shows the parameter you want to modify. With the arrow
buttons (fig. 2.3-9) you can adjust needed value and check it on the display (fig 2.5-5).
7. Melting. Put the metal into the crucible and push the “START” (fig. 2.3-2) button. The green LE (fig. 2.3-4) will
flash and machine will start to heat at previously set power level. Output power level can be changed during melting
cycle using arrow buttons.
8. The heating cycle can be stopped at any time by pressing “STOP” button (fig. 2.3-1).
9. If something is wrong the machine will go in “ERROR” state and the red LE (fig. 2.3-3) will flash. If the reason for
alarm condition is removed, you can escape “ERROR” state by pressing “STOP” button (fig. 2.3-1).
1.3 MAINTENANCE
1.3.1 SCHEDULING
The Power Supply is not designed for continuous operation. Every “HEAT ON” cycle must be followed by at least 5
minutes “HEAT OFF” period with working cooling fans. The frequency of any maintenance program is a function of
environment, degree of equipment use, and operator experience.
1.3.2 PE SONNEL
Qualified personnel must perform inspection and maintenance procedures only. Personnel must read and be
thoroughly familiar with all safety precautions discussed in this manual.
1.3.3 INSPECTION AND MAINTENANCE P OCEDU E
The following describes inspection procedures to be performed on a daily, weekly, and monthly basis.
Daily/Weekly Inspection: It is good practice to do a quick visual inspection of the unit, wiring and connections on a
daily and/or weekly basis. Report any apparent changes in performance to responsible personnel so that potential
problems can be investigated.
Monthly Inspection:
Perform the following on a monthly basis:
1. Ensure all wiring connections are secure. Visually inspect for any wear on cabling;
2. Verify that none of the enclosure hardware has become loose;
3. Remove any build-up debris that may occur around the fan inlet using a cloth or a vacuum cleaner. Using of
compressed air is not recommended;
4. Wipe the Control Panel with a damp cloth to remove any dirt, prints or spots;
5. Wipe the enclosure down with a damp cloth or paint friendly cleaner, if desired.

2.2.5 CONT OL MODES
Control Modes of Operation
There are two control modes of operation:
[Auto] –In this mode device automatically holds up previously set temperature of the crucible. In this mode thermo
regulator is switched ON (see Fig.2.6).
[Manual] – In this mode it is supposed that there is not thermocouple mounted. Thermo regulator is switched OFF
(see Fig.2.6) and operator has to watch crucible temperature.
Note:
When thermo regulator is switched OFF, the parameter “TEMPERATURE” is invisible on the 7 segment LED display.
3TUNING AND T OUBLESHOOTING
3.1 LOAD TUNING GUIDE
Because of fixed tank circuit and load (graphite crucible) device is factory tuned and doesn’t need additional load
tuning.
