WIRING

!
There is a reminder of the wiring diagram on the back of the controller.
Before wiring up, check on the label that the model corresponds to your requirements. Check that the values of the
power supply, input and output are not exceeded.

2.3.1. Power supply
In the case of a disturbed network (in particular if the installation comprises static relays operating by variation of the phase angle),
power the instruments via an insulating transformer. In the presence of networks with a high level of interference, use the appropriate
mains filters.
If the network is likely to be unstable, check that the value of the voltage supplied remains within the tolerance required by the
instrument (90...240 V AC). If necessary, use a voltage stabiliser.
Do not use the network terminals of the controller (terminals 1 and 2) to power the controls (contactors, relays, ...)
!
In a general way, the rules and standards of electrical installations must be followed and earth terminals must be
star mounted to the earth or linked to the protective conductor (equipotential link), with a cross section at least equal
to the cross section of the supply wires.
The enclosures or cupboards must be fitted with a sectioning device (contactors, differentials, fuses, ...) and the
power supply of the instruments must be provided from the most direct sectioning device.
2.3.2. Thermocouple input
The thermocouple input connections are shown on the right. An appropriate extension cable or
compensation cable must be used along the whole distance, between the controller and the thermocouple.
Ensure that the polarity is correct.
2.3.3. Pt 100 Ω Ω Ω Ω Ω input
The connection of a Pt 100 Ω is shown on the right, the line compensation is connected to input 14.
For a 2-wire Pt 100 Ω, terminals 13 and 14 must be bridged.
A 3-wire Pt 100 Ω compensates for the length of the line.
2.3.4. Linear DC signal
The DC voltage or current inputs are shown below.

Do not overtighten the screws. Make no connections to the unused terminals, as
+ -
they may be connected to internal circuits.
Precautions must be taken with the connections and, in particular, those
concerning the measurement input and the analogue outputs. These links are
sensitive to interference : use twisted and screened cables, with insulated
screening connected to the earth. Separate these links from power lines
(different cable runs) throughout their length. The same precautions must be
taken for ON-OFF links, such as the control logic output (for SSR command) and
the alarm outputs.
