INSTRUCTION
Triac controller for proportional control
of electric heating
220
TTC40FX is a proportional controller for electric heating with
automatic voltage adjustment. TTC40FX pulses the whole load On -
Off. The ratio between On-time and Off-time is varied 0 - 100% to
suit the prevailing heat demand. The current is always switched at
zero phase angle to prevent RFI.
TTC40FX can control both symmetrical Y-connected 3-phase
heaters and symmetrical or asymmetrical Delta-connected heaters.
TTC40FX is only intended for electric heating control. The control
principle makes it unsuitable for motor- or lighting control.
TTC40FX is intended for DIN-rail mounting.
Installation
Mount TTC40FX on a DIN-rail in a cabinet or other enclosure.
Mount TTC40FX vertically with the text right side up.
Protection class: IP20.
Ambient temperature: 0 - 40°C
N.B. TTC40FX emits approx. 70W of heat at full output which must
be dissipated.
Supply voltage (fig 1)
Terminals L1in, L2in and L3in.
Supply voltage: 210-255 or 380-415V AC
3 phase, 50 - 60 Hz with automatic voltage
adjustment.
Maximum current 40A/phase.
N.B. The supply voltage to TTC40FX should be wired via an all-pole
switch with a minimum contact gap of 3mm.
N.B. TTC40FX must be earthed.
Control signal (fig 2)
Terminals 8 and 9.
Terminal 8 = Signal neutral.
Terminal 9 = 0 - 10V DC.
0V input signal will give 0% output and 10V input will give 100%
output.
NOTE: Do not leave the input unconnected since an open circuit
will not give 0% output but approx. 50%.
To ensure 0% output when no control signal is connected the
control input should be short-circuited.

(4A).

Control principle
TTC40FX pulses the full load On - Off. TTC40FX adjusts the
mean power output to the prevailing power demand by
proportionally adjusting the ratio between On-time and Off-time.
The cycle time (=the sum of On-time and Off-time) is adjustable
0 - 60 seconds.
TTC40FX has zero phase-angle firing to eliminate RFI.
Start-up and fault finding
1. Check that all wiring is correct.
2. Measure the resistance between terminals L1out - L2out,
L1out - L3out and L2out -L3out:
At 230V phase-phase voltage: 6.4Ω<R<64Ω.
At 400V phase-phase voltage: 11.5Ω<R<115Ω.
3. Connect supply voltage and set the input signal to 10V DC.
The LED on the TTC40FX should be continuously on. Set the
control signal to 0V DC. The LED should be continuously off.
At inter-mediate positions the LED will pulse On-Off as the
TTC40FX pulses current to the heater. The pulse cycle
period is approx. 6 - 60 seconds depending on the setting of
the CT-potentiometer. Check with a clamp-on ammeter that
current is flowing to the heater.
