Safety Note:• Do not run current transformer input

wiring with AC power cables.Note:• Input impedance is equal to 10Ω.• Maximum input current is equal to 50 mA

(50/60 Hz).• The minimum time to perform this

measurement 400 msec.

Logic Input

L o g ic In pu t

Safety Note:• Do not run logic input wiring with AC

power cables.• Use external dry contact capable of

switching 0.5 mA, 5 Vdc.• The instrument requires at least 100 msec

to recognize a change in contact status• Logic input is not isolated by the measur-

ing input.

This input selects between SP and SP2 as theoperating setpoint. Input open = SP; inputclosed = SP2.

11

Inductive Loads

High voltage transients can occur when switch-ing inductive loads. Through the internal con-tacts these transients may introduce distur-bances which can affect instrument perfor-mance. For outputs 1 and 2, the internal pro-tection (varistor) assures protection up to 0.5Amps of inductive component.

The same problem can occur when a switch isused in series with the internal contacts asshown:

P O W E R L IN E

In this case, it is good electrical practice to in-stall and additional RC network across theexternnal contacts as shown. The value of ca-pacitor (C) and resistor (R) are shown in the fol-lowing table.Load C R P OperatingCurrent (µF) (Ω) (W) Voltage<40 mA 0.047 100 1/2 260 Vac<150 mA 0.1 22 2 260 Vac<0.5 Amp 0.33 47 2 260 Vac< 1 Amp 0.47 47 2 260 Vac

Operating Key FunctionsFUNC = In the normal display mode:

• Press for less than three secondsto start the parameter modificationprocedure.

• Press for three to ten seconds tochange lower (or right) indication.See "Display Function."

• Press for ten seconds to enablethe lamp test. See "Lamp Test."

FUNC = During parameter modification:New setting of the selected param-eter is stored and the next parameteris displayed (in increasing order).

MAN = In the normal display mode:Press for more than one second toenable or disable the manualfunction.

MAN = During parameter modification:Scrolls back through the parameterswithout storing the new setting.

s = During parameter modification:Increases the setting of the selectedparameter.

s = During manual mode:Increases the output value.

t = During parameter modification:Decreases the setting of the selectedparameter.

t = During manual mode:Decreases the output value.

s +MAN =During parameter modification:Jumps to the maximum program-mable value.

t + MAN = During parameter modification:Jumps to the minimum program-mable value.

Note: A 10 or 30 second timeout (P39) 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 changed.

Enable/Disable the Control OutputWith the instrument in the normal display mode,press and hold for five seconds the s key andthe FUNC key to disable the control outputs.The device will then function as an indicator. Allcontrol outputs will be OFF and the word OFFwill appear in the lower (or right) display. Alarmswill be in a non-alarm condition. The alarm out-put conditions depend on the alarm action type(see P21-P23-P25). Press and hold for five sec-onds the s key and the FUNC key a secondtime to restore the control status. If the alarmstandby function has been configured, alarmswill respond as though it were a power-up con-dition. If a shut down occurs when the controlis disabled, control output will be disabled againat instrument power-up.

26

Output 1 Failure DetectionFor the load driven by OUT 1, the instrumentwill measure and display:

• current running in the load when theload is energized

• leakage current flowing through the loadwhen the load is de-energized

If P10 parameter has been correctly set, the in-strument generates an alarm when:

• current running through the load is lowerthan the "Hbd" parameter value. (Itshows a partial or total breakdown of theload, the breakdown of the actuator, or apower down due to a protection or fuseintervention).

• leakage current is higher than the "SCA"parameter value. (It shows a shortcircuit of the actuator).

The "Display Function" paragraph describeshow to show the two current values. A faultcondition is shown by OUT 3 LED flashing, andby OUT 3 relay status.

If the on or off period is more than 400 ms, therelative measurement couldn't be performed andthe instrument will show flashing the last mea-sured value.

Manual FunctionThe manual mode can be accessed (if P30 =On) by pressing the MAN key for one second.The command is accepted and executed only ifthe display is in the normal display mode. Whenin the manual mode, the MAN LED is lit and the

lower display shows the power output values.The value of OUT 1 is shown in the two mostsignificant digits field while the value of OUT 2(if present) is shown in the two least significantdigits field. The decimal point between the twovalues will be flashing to indicate the instrumentis in manual mode.

Note: “ “ is used for OUT1 = 100 “ “ is used for OUT2 = 100

Power output can be modified by using the sand t keys. Hold for two seconds the MAN keyagain to return the device to the AUTO mode.

The transfer from AUTO to MANUAL and backis bumpless (this function is not provided if in-tegral action is excluded). If the transfer fromauto to manual occurs during the first part ofthe autotuning (Smart AT) algorithm (tune), whenit return to AUTO mode, instrument will be forcedautomatically to the second part of theautotuning algorithm (ADAPTIVE).

At power-up, the instrument will be in the AUTOmode or in the mode it was in prior to powershutdown (depending on P37).

Note: When start-up occurs in the manual mode,the power output (OUT1 - OUT2) is set to 0.

Setpoint AccessWhen the instrument is in AUTO mode and inthe normal display mode, SP and SP2 can bedirectly accessed.

27

Press the s or t key (and hold for two sec-onds); the setpoint will start to change. The newsetpoint becomes operative since no key hasbeen pressed at the end of two second timeout.

SP/SP2 SelectionThe operating setpoint (SP or SP2) can beswitched only by an external contact (terminals7 and 8). By setting P45, it is possible to dis-play the final or operating setpoint during rampexecution.

Serial LinkThis instrument can be connected to a host com-puter by a serial link. The host computer canput the instrument in either LOCAL (functionsand parameters are controlled by the keys) orREMOTE (functions and parameters are con-trolled by serial link). REMOTE is signified bythe LED labeled RMT.

To download instrument configuration throughthe serial link proceed as follows;1) Serial parameters SEr1 through SEr4 must

be properly configured from the keys.2) The instrument must be in the operating

mode.

During downloading of the configuration, the in-strument goes into open loop control with alloutputs in OFF state. At the end of the configu-ration procedure, the instrument performs an au-tomatic reset and returns to closed loop con-trol.

Autotuning (Smart AT)Autotuning is used to automatically optimize thecontrol action. To enable autotuning, press theFUNC key until “Snrt” appears. Press the s ort key to set the display to “On” and then pressthe FUNC key. The AT LED will turn on or beginflashing according to the selected algorithm.When autotuning is enabled, the control param-eters (Pb, ti, td, rC) can be displayed but notmodified.

To disable autotuning, press the FUNC key until“Snrt” appears. Press the s or t key to set thedisplay to “OFF” and press the FUNC key again.The AT LED will turn off. Once autotuning isturned off, the instrument maintains the calcu-lated control parameters, but allows the param-eters to be modified.

Note: Autotuning is disabled when Pb = 0 (ON/OFF control). Autotune enable/disable can beprotected by a password (see P31).

Lamp TestWhen it is desired to verify the display efficiency,push FUNC button for more than 10 seconds.The instrument will turn on with a 50% duty cycleall LEDs. Lamp test does not time out – to re-turn to normal display mode, push FUNC but-ton again. During lamp test, the instrument con-tinues to control the process, but keyboard func-tions are not available, except FUNC.

A calibration check can be initiated with-out making an entry: press the FUNC key toadvance to the desired calibration check. Theupper or left display will show the parametercode (t. - rJ. - P. - nA. - 5U. - 10U. - Ct.) and thelower or right display will show "ON" or "OFF".

Before beginning calibration, be sure internalswitch V2 is open (see Configuration Procedure,Figure 1).

General Guidelines

a) The instrument should be mounted in itscase 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 as de-scribed in the Configuration section mustbe made.
