Relay output: Protected by varistor againstinductive load with inductive component upto 0.5A.OUT 1: Contact rating of 3A/250 Vac on resis-tive load; contact rating of OUT 2 is 2A/250 Vacon resistive load.OUT 3: Contact rating of 2Amp/250 Vacresistive load.OUT 4: Contact rating of 2Amp/250 Vacresistive load. Number of operations: 1 x 105 atspecified rating.

Alarm 2 and alarm 3 are in OR condition on theOUT 4.

The following recommendations avoid seriousproblems which may occur when using relayoutput for driving inductive loads.

Values of capacitor (C) and resistor (R) are:Load C(µF) R (ohms) P(W) R & C V<40 mA 0.047 100 1/2 260 Vac<150 mA 0.1 22 2 260 Vac<0.5 A 0.33 47 2 260 Vac<1 A 0.47 47 2 260 Vac

Relay output wiring must be as far away as pos-sible from input wiring and communicationcables.

High voltage errors may occur switching induc-tive loads. Through the internal contacts, thesetransients may introduce disturbances whichcan affect instrument performance. For all out-puts, the internal protection (varistor) assurescorrect protection up to 0.5 Amps of inductivecomponent.

The same problem may occur when a switch isused in series with the internal contacts asshown bellow. In this case it is good practiceto install an additional RC network across theexternal contact as shown.

The two relay outputs are interlocked.1) Before connecting the instrument to the

power line, make sure the line voltage andload current are in accordance with thecontact rating (3A/250 Vac on resistiveload).

2) To avoid electric shock, connect powerline at the end of wiring procedure.

3) For servomotor connections, use No. 16AWG or larger wires rated for at least75°C.

4) Use copper conductors only.

5) Do not run input wires together withpower cables.

6) For feedback potentiometer, use shieldedcable with the shield connected to theearth at one point only.

7) Relay outputs are protected by varistoragainst inductive load with inductivecomponent up to 0.5 A.

Operating KeysFUNC = When in the normal display mode:

1) Press for less than 3 seconds toenter the parameter modificationmode.2) Press for 3 to 10 seconds tochange the lower display (see"Displays").3) Press for more than 10 seconds tostart a lamp test.During parameter modification, thenew setting of the selected parameteris stored and the next parameter isdisplayed (in increasing order).

MAN =Pressing and holding for more than 1second enables/disables the manualfunction.During parameter modification itscrolls the parameters back withoutstoring the new setting.

s = During AUTO mode, it increases thevalue of the selected parameter.During MANUAL mode, it closes theOUT 1 (s) relay contact.

t = During AUTO mode, it decreases thevalue of the selected parameter.During MANUAL mode, it closes theOUT 2 (t) relay contact.

s+MAN = During parameter modification theyenter the maximum programmablevalue.

t+MAN = During parameter modification theyenter the minimum programmablevalue.

A 10 or 30 second timeout (see P46) can beselected for parameter modification. If no keysare pressed during this time period, the instru-ment goes automatically to the normal displaymode and the last parameter is NOT stored.

Feedback Potentiometer CalibrationThis function is available only if closed loop ser-vomotor control (P5 = "Sn.CL") or a servomotorcontrol open loop with feedback indication(P5="Sn.OL" and P6 = "Fb.") has been selectedduring configuration procedure:

1) Switch On the instrument.2) Press the MAN key for more than one

second. The MAN LED will light and theinstrument will change to MANUAL mode.

3) Repeatedly press the FUNC key until"F.CAL" appears on the lower display.

4) Press the s or t key to select "ON" andpress the FUNC key. The upper displaywill show the valve position (in percent)and the lower display will show themessage "POS.L."

5) Repeatedly press the s or t key to setthe servomotor to the beginning of itsstroke.

6) Press the FUNC key. The display willshow "Fb.LC" (feedback low limitcalibration).

7) Press the s or t key to select "ON" andpress the FUNC key. The upper displaywill show the valve position (in percent)and the lower display will show themessage "POS.H."

27

8) Repeatedly press the s or t key to setthe servomotor to the end of its stroke.

9) Press the FUNC key. The display willshow "Fb.HC" (feedback high limitcalibration).

10) Press the s or t key to select "ON" andpress the FUNC key. This sets the newfeedback potentiometer calibration andreturns to the MANUAL mode.

Notes:1) The minimum span (Fb.LC - FbHC) for the

instrument is equal to 20% of thepotentiometer stroke.

2) The instrument is able to assure a 1%resolution for the potentiometer indicationonly if the calibrated span is greater than50% of the potentiometer stroke.

Enable/Disable Control OutputWhen the instrument is programmed for servo-motor control, this function is not available.

To disable the control outputs when the instru-ment is in the normal display mode, press andhold (for more than five seconds) the s andFUNC keys. In this open loop mode the devicewill function as an indicator, the lower displaywill show the word OFF and all control outputsand alarms will be OFF. The alarms output con-dition depends on the alarm action type (seeP26 thru P28).

To restore the control outputs, press and hold(for more than five seconds) the s and FUNCkeys. The alarm standby function, if configured,will be activated as if a power-up condition oc-curred. If a shut down occurs when the controloutput is disabled, the control output will re-main disabled at instrument power-up.

Manual ModeMANUAL mode can be accessed (only if P38 =On) by pressing the MAN key for more than onesecond or by closing external contact 2 (seeP24). The key command is accepted and ex-ecuted only if the display is in the normal dis-play mode. Commands from external contactsare always accepted.

When in MANUAL mode the MAN LED will belit. The lower display will show the valve posi-tion (if configured) or power output value if atime proportioning control output is configured.When time proportioning control output is con-figured, the power of the "rEv" output is shownin the two most significant digits while the powerof the "dir" output (if present) is shown in thetwo least significant digits. The decimal pointbetween the two values will be flashing to indi-cate the instrument is in MANUAL mode.

Note: The instrument shows "rEv" output = 100with the graphic symbol " ." The instru-ment shows "dir" output = 100 with the graphicsymbol " ."

28

Power output can be modified by using the sand t keys. By pressing the MAN key for morethan one second, or by opening contact 2, theinstrument returns to AUTO mode. The trans-fer from AUTO to MANUAL will be in accordancewith the P40 parameter set. The transfer fromMANUAL to AUTO will be bumpless (this func-tion is not provided if integral action is excluded).If the transfer from AUTO to MANUAL is per-formed during the first part of autotuning, (TUNE)when returning to AUTO the instrument will beforced automatically to the second part ofautotuning (ADAPTIVE).

At power-up the instrument will start as deter-mined by P39. When configured for two con-trol outputs and start-up occurs in MANUALmode with power output set to 0, the outputsignal will be in accordance with the formula:

"rEv" output - "dir" output = 0.

When AUTO/MANUAL control is selected bylogic input and P39 = 0 or 1, the instrument startsin accordance to the logic input status and, forMANUAL mode, it will start with a power outputequal to zero.

Direct Access to SetpointsWhen the instrument is in AUTO mode and inthe normal display mode, it is possible to di-rectly modify the selected setpoint (SP, SP2, SP3or SP4). Pressing s or t for more than twoseconds, the setpoint will begin changing. Thenew setpoint value becomes operative at theend of a two second timeout as long as no keysare pressed.

Setpoint SelectionYou can select the operating setpoints only bythe binary combination of logic inputs 1 and 3:Input 3 Input 1 Operating Setpointopen open SPopen close SP2close open SP3close close SP4

With P50, you can limit the number of setpointsavailable.

Serial LinkThe instrument can be connected to a host com-puter by a serial link. The host can put the in-strument in LOCAL (functions and parametersare controlled via keys) or REMOTE (functionsand parameters are controlled via serial link)mode. REMOTE status is signalled by an LEDlabeled RMT. Instrument configuration can bedownloaded through the serial link when the fol-lowing conditions are met:1) Serial parameters from SEr1 to SEr4 are

properly configured.2) The instrument is in OPERATING mode.

During downloading of configuration, theinstrument goes in open loop with alloutputs in OFF state.

Note: It is not possible to perform the feed-back potentiometer calibration or the action per-formed by logic input 2 (Cnt 2) from the seriallink.

At the end of the configuration procedure, theinstrument performs an automatic reset and re-turns to closed loop control.

29

Autotuning (Smart AT)Autotuning is used to automatically optimize thecontrol action. At instrument power-up, ifautotuning is ON, the second autotuning algo-rithm will be enabled.

When ON/OFF control is programmed (Pb = 0),autotuning is disabled. Autotuning enabling/dis-abling can be protected by a safety key pass-word (see P33).

To enable autotuning, repeatedly press theFUNC key until "Snrt" is shown. Press the sor t key to change the display to "On" andpress the FUNC key. The AT LED will turn on orcontinuously flash according to the selected al-gorithm. When autotuning is enabled, it is pos-sible to display but not to modify the controlparameters (Pb, ti, td, and rC).

To disable autotuning, repeatedly press theFUNC key until "Snrt" is shown. Press the s ort key to change the display to "OFF" and pressthe FUNC key. The AT LED will turn off. Theinstrument will maintain the control parametersand will enable parameter modification.

Lamp TestTo test the display LEDs, press the FUNC keyfor more than 10 seconds. All LEDs will turn onwith a 50% duty cycle. No timeout is appliedto the lamp test. Press the FUNC key again toreturn to the normal display mode. During thelamp test, the instrument continues to controlthe process but no keyboard functions, exceptFUNC, are available.

Operating ParametersPress the FUNC key, the lower display will showthe code while the upper display shows thevalue or status (ON or OFF) of the selected pa-rameter.

• When the instrument detects anUNDERRANGE and direct action isassigned to the servomotor output, OUT 1(s) turns OFF while OUT 2 (t) turns ON.

Sensor lead breaks can be signalled as:• for TC/mV input: OVERRANGE or

UNDERRANGE (selectedby a solder jumper)

• for RTD input: OVERRANGE• for mA/V input: UNDERRANGE

On the mA/V input the lead break can be de-tected only when the range selected has a zeroelevation (4/20 mA, 1/5 V or 2/10 V). On RTDinput a special test is provided to signalOVERRANGE, when input resistance is less than15 Ohms (short circuit sensor detection).

If the instrument appears to be malfunctioningor operating in an unexplained manner:1. Load default configuration parameters.2. Short inputs.3. Remove outputs.4. Move setpoints to room temperature and

vary the setpoints to see if the controlleroutput responds in expected manner.

Power UpOn power-up, the instrument performs a self-diagnostic test. When an error is detected, thelower display shows the “Err” indication whilethe upper display shows the code of the de-tected error.

CALIBRATION

Calibration parameters are logically divided intogroups of two parameters each – initial scalevalue and final scale value. A calibration checkis provided after entering the values of eachgroup. A calibration check can be initiated with-out making an entry: press the FUNC key toadvance to the desired calibration check. Thelower display will show the parameter code (t.,rJ., etc.) and the upper display will show “on”or “off.” Press the s or t key to select on oroff.

To go to the next parameter without modifyingthe calibration, press the FUNC key when thedisplays shows “off.” To return the previous pa-rameter without modifying the calibration, pressthe MAN key.

To set the parameter calibration, press the FUNCkey when the display shows “on.” The displaywill blank, and only the decimal point of the LSDof the lower display will be lit during the calibra-tion step.

Before beginning calibration, be sure internalswitch V2 is open (see "Preliminary HardwareSettings," Figure 1).

General Guidelinesa) The instrument should be mounted in its

case in order to keep the internaltemperature constant.

b) Ambient temperature should be stable.Avoid drift due to air conditioning or othermechanical devices.

c) Relative humidity should not exceed 70%.d) Minimum warm up time should be at least

20 minutes.e) Operate as much as possible in a noise

free environment.f) During calibration, connect one input at a

time to the rear terminal block.g) Before input calibration, the specific

preliminary hardware settings describedinthe Configuration section must be made.

h) Use calibrators with the following:AccuracyCurrent Input:
