Man 5001266
The N322-PID is a 2- utput digital electr nic c ntr ller with PID c ntr l alg rithm, intended f r
heating and c ling applicati ns. The input sens rs available are NTC thermist r, Pt100 r
J/K/T type therm c uples. Sens r ffset c rrecti n is pr vided. The 2 independent utputs
can be used as c ntr l r alarm.
The features f a particular m del (input sens r type, sens r range, mains supply, etc) are
identified by the label placed n the c ntr ller b dy.

It is imp rtant t f ll w the rec mmendati ns bel w:
• Signal wires sh uld be installed in gr unded c nduits and away fr m p wer r c ntact r
wires.
• The instrument sh uld have its wn p wer supply wires that sh uld n t be shared with
electrical m t rs, c ils, c ntact rs, etc.
• Installing RC filters (47 R and 100 nF, series c mbinati n) is str ngly rec mmended at
c ntact r c ils r any ther induct rs.
• System failure sh uld always be taken int acc unt when designing a c ntr l panel t
av id irreversible damage t equipment r pe ple.
OPERATION
The c ntr ller requires the internal parameters t be c nfigured acc rding t the intended use
f r the instrument. The parameters are rganized in 4 gr ups r levels:
Level Function
0 Temperature measurement
1 Setp int Adjustment
2 C nfigurati n
3 PID c ntr l parameters
4 Calibrati n
Up n p wer-up, the c ntr ller display sh ws f r 1 sec nd its firmware versi n. This
inf rmati n is useful when c nsulting the fact ry.
Then, the temperature measured by the sens r is sh wn n the display. This is the parameter
level 0 (temperature measurement level).
T access level 1, press f r 1 sec nd until the “SP1
SP1SP1
SP1” message sh ws up. Pressing
again, the “SP2
SP2SP2
SP2” parameter is presented. T g back t level 0, press nce m re.
T access level 2 f paramenters, press f r 2 sec nds until the “uNT
uNTuNT
uNT” message is
sh wn. Release the key t remain in this level. Each new pressing n the key will
advance t the next parameter in the level. At the end f the level, the c ntr ller returns t the
first level (0). Use the and keys t alter a parameter value.
Notes: 1 A parameter c nfigurati n is saved when the key is pressed t advance t
the next parameter in the cycle. The c nfigurati n is st red in a n n-v latile
mem ry, retaining its value when the c ntr ller is de-energized.
2If n keyb ard activity is detected f r ver 20 sec nds, the c ntr ller saves the
current parameter value and returns t the measurement level.

ORKING ITH THE CONTROLLER
Multiple utput c ntr llers are suited f r c ntr lling multiple stage systems.
Other applicati ns require OUTPUT 1 t be the c ntr l utput and OUTPUT 2 t be the alarm.
There are eight distinct alarm functi ns implemented in OUTPUT 2, selected by the parameter

Bl cking feature, which inhibits the utput if an alarm c nditi n is present at start-up. The

In a multiple stage applicati n, SP1
SP1SP1
SP1 and SP2
SP2SP2
SP2 are c nfigured t perate at different
temperatures, creating a pr gressive sequence f r turning n the utputs (c mpress rs) in
resp nse t a system demand. The utput delays f r turning n the c mpress rs (dL1
dL1dL1
dL1 and
dL2
dL2dL2
dL2) cause the c mpress rs t be turned n ne by ne, minimizing energy demand.
An ther usage f r multiple utput c ntr llers is in systems that require aut matic selecti n
between c l and heat acti n. In these applicati ns, ne utput is c nfigured as reverse
acti n (heating) and the ther as direct acti n (refrigerati n). The utput status led P1 and P2
in the c ntr ller panel, signals when the c ntr l utput in n.

Important notes:
1- After five c nsecutive attempts t enter a wr ng passw rd, new tentative will be bl cked f r

MASTER PASS ORD
The master passw rd all ws user t define a new passw rd f r the c ntr ller, even if the
current passw rd is unkn wn. The master passw rd is based in the serial number f the

[ 1 ] + [ higher digit f SN2 ] + [ higher digit f SN1 ] + [ higher digit f SN0 ]
f r example the master passw rd f r the device with serial number 987123465 is: 1 9 3 6
