NOTE: a single switch or circuit-breaker can drive more than one instrument. 9) When the NEUTRAL line is present, connect it to terminal 4. 8 1604-7-1-AB.
OPEN INPUT CIRCUIT This instrument is able to identify the open circuit for TC and RTD inputs. The open input circuit condition for RTD input is shown by an "overrange" indication. For TC input, it is possible to select overrange indication (standard) or underrange indication setting the CH101 and SH101 according to the following table: Overrange (STD) CH101 = close SH101 = open Underrange CH101 = open SH101 = close PRELIMINARY HARDWARE SETTINGS 1) Remove the instrument from its case.
SEr3 = Baude rate for serial link Not available when SEr1 = OFF From 600 to 19200 baud. NOTE: 19200 baud is shown on display as 19.2. GENERAL NOTES for configuration. FUNC = This will memorize the new value of the selected parameter and go to the next parameter (increasing order). MAN = This will scroll back the parameters without memorization of the new value. s = This will increase the value of the selected parameter t = This will decrease the value of the selected parameter.
the input range. When this parameter is modified, rH parameter will be re-aligned to it. The initial and full scale values determine the input span which is used by the PID algorithm, the SMART and the alarm functions. 21 = TC type J range -150 / +1830 °F 22 = TC type K range -150 / +2500 °F 23 = TC type T range -330 / +750 °F 24 = TC type N range -150 / +2550 °F 25 = TC type R range 0 / +3200 °F 26 = TC type S range 0 / +3200 °F 27 = RTD type Pt 100 range-199.9 / +400.
L.A. = Low alarm (inside for band alarm) with automatic reset (latched). H.L. = High alarm (outside band) with manual reset (latched). L.L. = Low alarm (inside band) with manual reset (latched). P7 = analog retransmission - initial scale value. Available only when P5 = Pv.rt or SP.rt. It is programmable from -1999 to 4000. The decimal point will be positioned as selected with P2 parameter. P8 = analog retransmission - full scale value. Available only when P5 = Pv.rt or SP.rt.
P16 = Threshold of the “Soft Start” function. Threshold value in eng. units to initiate the "Soft start" function (output power limiting) at start up. Range : within the readout span. NOTE: This threshold value will not be taken into account when tOL = InF. P12 = Alarm 2 operating mode Available only when P11 is equal to "AL2.P", "AL2.b" or "AL2.d". H.A. = High alarm (outside for band alarm) with automatic reset (latched). L.A. = Low alarm (inside for band alarm) with automatic reset (latched). H.L.
P21 = Displayed value of the power output for the secondary control output This parameter is available only when two control outputs are configured. nOrL = the displayed value is equal to the result of PID calculation. CnPL = the displayed value is complemented (100 - PID calculation). NOTE: when two control outputs are configured, the P18 and P19 selections are applied to the "rEv" control output while P20 and P21 selections are applied to the "dir" control output.
NOTE: for more details to stand-by (mask) function, see P25 parameter. P24 = Alarm 1 action Available only when P9 = "AL1.P", "AL1.d" or "AL1.b". dir = direct action (relay energized in alarm condition) rEV = reverse action (relay de-energized in alarm condition) P28 = OFFSET adjustment added to the measured value This parameter allows to set a constant OFFSET throughout the readout range. It is skipped for linear inputs - For readout ranges with decimal figure, P28 is programmable from -19.9 to 19.9.
P31 = Maximum value of the proportional band calculated by the SMART algorithm. This parameter is skipped when none of the outputs is programmed as control output or P30=0. This parameter is programmable from P32 value to 200.0 %. 2 = the instrument starts in the same way it was left prior to power shut down but if the instrument was in manual mode, it will restart with a power output equal to 0.
negative value decreases the low limit of the antireset-wind up (under set point). NOTE: when the instrument detects an out of range condition, it assignes the P38 value to the PID output but P18 and P20 parameter are still active. P43 = Set point indication Fn.SP = during operative mode, when the instrument performs a ramp, it will show the final set point value. OP.SP =during operative mode, when the instrument performs a ramp, it will show the operative set point.
When return in "Normal Display Mode" is desired, push FUNC push-button again. OPERATIVE MODE 1) Remove the instrument from its case. 2) Set the internal dip switch V101 in closed condition 3) Re-insert the instrument. 4) Switch on the instrument. INDICATORS °C Lit when the process variable is shown in Celsius degrees. °F Lit when the process variable is shown in Fahrenheit degrees. SMRT Flashing when the first part of the SMART algorithm is active.
NOTE: a 10 or 30 seconds time out (see P 36) can be selected for parameter modification during run time mode. If, during operative parameter modification, no pushbutton is pressed for more than 10 (30) seconds, the instrument goes automatically to the “normal display mode” and the eventual modification of the last parameter will be lost. Pushbutton functionality during operating mode.
DIRECT ACCESS TO SET POINT When the device is in AUTO mode and in “Normal Display Mode”, it is possible to access directly to set point modification (SP or SP2). Pushing s or t for more than 2 s, the set point will begin changing. The new set point value becomes operative since no pushbutton has been depressed at the end of 2 s timeout. The transfer from AUTO to MANUAL and viceversa is bumpless (this function is not provided if integral action is excluded).
SERIAL LINK The device can be connected to a host computer by a serial link. The host can put the device in LOCAL (functions and parameters are controlled via keyboard) or in REMOTE (functions and parameters are controlled via serial link). The REMOTE status is signalled by the decimal point (labelled REM) at the right hand of the LSD of the upper display. This instrument allows to modify the operative and configuration parameters, via serial link.
OPERATIVE PARAMETERS Push the FUNC pushbutton, the lower display will show the code while the upper display will show the value or the status (On or OFF) of the selected parameter. By s or t pushbutton it is possible to set the desired value or the desired status. Pushing the FUNC pushbutton, the instrument memorizes the new value (or the new status) and goes to the next parameter. Some of the following parameter may be skipped according to the instrument configuration. AL1 Param.
HyS ti td IP Cy2 Note:When device is working with SMART algorithm the Pb value will be limited by P31 and P32 parameters. Hysteresis for ON/OFF control action This parameter is available only when Pb=0. Range: from 0.1% to 10.0% of the input span. Integral time This parameter is skipped if Pb=0 (ON/ OFF action). Range: from 00.01 to 20.00 [mm.ss]. Above this value the display blanks and integral action is excluded.
Grd1 Grd2 OLH tOL rnP Ramp applied to an increasing set point change Range: from 1 to 100 digits per minute. Above this value the display shows “InF” meaning that the transfer will be done as a step change. Ramp applied to a decreasing set point changes For other details see Grd1 parameter. Output high limit Range: - From 0.0 to 100.0 % of the output span when device is configured with one control output. - From -100.0 to 100.0% of the output span when device is configured with two control outputs.
When P37 is different from zero and an out of range condition is detected, the instrument operates in accordance with P37 and P38 parameters. ERROR MESSAGES OVERRANGE, UNDERRANGE AND SENSOR LEADS BREAK INDICATIONS The device is capable to detect a fault on the process variable (OVERRANGE or UNDERRANGE or SENSOR LEADS BREAK).
