CONGRATULATIONS
Congratulations on your purchase of one of the easiest to
configure controllers on the market. After a four step
configurationprocedure,yourprocesswillbeupandrunning.
GUIDE TO SIMPLE SET-UP
Only four steps are required to set-up your controller:
1. Wire the instrument (page 7).
2. Configure the instrument (page 13).
3. Check the operating mode parameters (page 24).
4. Check the autotune (Smart AT) process (page 20).

MOUNTING REQUIREMENTS
Select a mounting location with the following
characteristics:
1) Low vibration.
2) An ambient temperature range between 0 and 50 °C
(32 and 122 °F).
3) Easy access to the rear of the instrument.
4) No corrosive gases (sulfuric gas, ammonia, etc.).
5) No water or other fluid (i.e., condensation).
6) A relative humidity of 20 to 85% non-condensing.
The instrument can be mounted on a panel up to 15 mm
(0.591in) thickwithacutoutof45x92mm(1.772 x3.622
in) - see outlinein “Dimensions and Panel Cutout.”
Panel surface texture must be smoother than 6.3 µm.
ToassureIP65 andNEMA 4Xprotection,insert thepanel
gasket between the instrument and the panel as shown
below.
Install the instrument as follows:
1) Insert the instrument case in the gasket.
2) Insert the instrument in the panel cutout.
3) Pushing the instrument against the panel, insert the
mountingbracket.
4) Torquethemountingbracketscrewsbetween 0.3and
0.4 Nm (0.25 and 0.32 lbin).
5) Make sure the instrument will not move within the
cutout to insure NEMA 4X/IP65 protection.

NOTE: Control outputs 1 and 2 are protected by v
aristoragainstan inductiveloadupto0.5Amps.
All other outputs, or external contacts in series
with the instrument outputs, need an external
snubber network (RC) across the terminals:

SAFETY NOTE:
1) Do not run RTD wires with power cables.
NOTES:
1) Ground shielded cable at one end only.
2) Use the correct size copper wires.
3) The resistance of the 3 wires must be the same.
4) Pay attention to line resistance: high line resistance
(higher than 20 Ω/wire) can cause measurement
errors.
Any external components (like zener diodes, etc.)
connectedbetweenthe sensor and inputterminals may
causemeasurementerrors(excessiveor unbalancedline
resistance or possible leakage currents).

SAFETY NOTE:
1) Do not run input wires with power cables.
NOTES:
1) For TC wiring use proper compensating cable,
preferably shielded.
2) Shielded cable should be grounded at one end only.

A.2) Current transformer input
SAFETY NOTE:
1) Do not run current transformer input wiring with AC
power cables.
NOTE:
1) The minimum active period to perform this
measurement is 50 ms.
2) The input impedance is 10 Ω.
3) The maximum input current is 50 mA.
This input measures the current used by OUT 1.

OUT3: Contact ratingof 2 Amps/250Vac resistiveload.
The output 2 and the NO contact of the output 1 are
protected by varistor from inductive load with an
inductive component up to 0.5 A. The number of
operations is 1 x 105at specified rating.
Notes:
1) To avoid electric shock, cponnect power line at the
end of wiring procedure.
2) For power connections, use no. 16 AWG or larger
wires rated for at least 75°C.
3) Use copper conductors only.
4) Don’t run input wires together with power cables.
5) RelayoutputandSSRdriveroutputarebothavailable.
When a relay output is desired, it is necessary to enable
the relay output, and viceversa. See “Preliminary
Hardware Settings.”
