The TC3001 thyristor unit operating voltage must be as close as possible to the
supply voltage to prevent problems of non-operation in the event of a voltage
drop less than 70 % of the nominal voltage (after calibration).
The calibration voltage (the operating voltage) is considered as the nominal
voltage of the thyristor unit.

The thyristor units can be fixed with their protective covers in place.
However, for configurqtion, the upper protective cover must be removed.
In order to do this, open the door by unfastening the front screw located at the top left of the
door. Then raise the door in order to release it from its notches and open it completely by
pulling it towards you.

Danger !
Cabling must be performed by personnel who are qualified to work with low
voltage electrical equipment.
It is the user's responsibility to cable and protect the installation in accordance
with current professional standards.
A suitable device guaranteeing electrical separation of the equipment and the
supply must be installed upstream from the unit in order to perform the operation
in complete safety.

Star with neutral configuration
If the load is wired in 'Star with Neutral' (4 wires), the neutral must also be connected to
the neutral terminal block (terminal 71) below the thyristor unit.
In the 'Phase angle' firing mode, the neutral current contains the sum of the 3rd harmonics of
each phase. For small firing angles (less than 60°), the current passing in the neutral of the
loads can be up to 2 times greater than the line current.

If retransmission of the controlled parameter has been configured, the internal feedback signal is
available between terminals 17 ('0 V ANA') and 12 in the form of a DC signal with a scale
0-10V. This retransmission represents:
• the mean of the squares of the three RMS currents,
• or the RMS voltage of the squared load,
• or the apparent power ( Iave.rms x Vrms load ).

The 'Current limit' corresponds to the value of the current threshold allowed by the load. This

The current limit setpoint can come from :

• or an external analogue signal in cascade with the front panel potentiometer.
The current limit setpoint can come from :

eliminate the DC component generated on each phase, firing rotation is performed (patented by
Eurotherm Automation).

For inductive loads, firing at zero voltage generates transient operation which may, in certain
cases, induce a saturation of the magnetic circuit (see fig.5-6,a) and a high speed fuse blow-out
(thyristor protection).
For inductive loads, firing at zero voltage generates transient operation which may, in certain
cases, induce a saturation of the magnetic circuit (see fig.5-6,a) and a high speed fuse blow-out

To prevent this saturation, the firing on each phase can be delayed with reference to the
corresponding zero voltage (see figure 5-6,b).

The 'Burst firing' mode is a proportional cycle which consists of supplying a series of

Thyristor firing and non-firing are synchronised with the supply and are performed at zero

order to rebalance the power consumption of the 3 phases and to eliminate the DC component
(firing signal rotation is covered by a Eurotherm patent).

THYRISTOR PROTECTION
The thyristors of the TC3001 series thyristor units are protected as follows:
The thyristors of the TC3001 series thyristor units are protected as follows:
•
the internal high speed fuse against significant over-currents
(e.g. short-circuit)
• the RC snubber and the varistor against too fast voltage variations
and transient over-voltages when the thyristors are not firing.
• the thermal switch (in the event of accidental overheating of the cooler
the thermal switch opens, which causes the thyristor firing to be stopped).
•
