1 MOUNTING REQUIREMENTS Select a mounting location where there is minimum vibration and the ambient temperature range between 0 and 50 °C. The instrument can be mounted on a panel up to 15 mm thick with a square cutout of 45 x 45 mm. For outline and cutout dimensions refer to Fig.

3 CONNECTION DIAGRAMS Connections are to be made with the instrument housing installed in its proper location. Fig. 3 .A REAR TERMINAL BLOCK A) MEASURING INPUTS NOTE : Any external components (like zener barriers etc.
4 LINEAR INPUT Fig. 6 mA, mV AND V INPUTS WIRING NOTE : 1) Don’t run input wires together with power cables. 2) Pay attention to the line resistance; a high line resistance may cause measurement errors. 3) When shielded cable is used, it should be grounded at one side only to avoid ground loop currents.
5 B) LOGIC INPUT Safety note: 1) Do not run logic input wiring together with power cables. 2) Use an external dry contact capable of switching 0.5 mA, 5 V DC. 3) The instrument needs 100 ms to recognize a contact status variation. 4) The logic inputs are NOT isolated by the measuring input Fig.
6 LINEAR OUTPUT This instrument is equipped with one linear output (OUT 1) programmable as: - main output (heating or cooling) - secondary output (cooling) - analog retransmission of the measured value - analog retransmission of the operative set point.
7 SERIAL INTERFACE RS-485 interface allows to connect up to 30 devices with one remote master unit. Fig. 11 - RS-485 WIRING The cable length must not exceed 1.5 km at 9600 BAUD. NOTE : The following report describes the signal sense of the voltage appearing across the interconnection cable as defined by EIA for RS-485.
8 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. 1604-7-1-AB.
9 PRELIMINARY HARDWARE SETTINGS 1) Remove the instrument from its case. 2) It is necessary to set J106 according to the desired input type as shown in the following figure.
10 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.
11 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.
12 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.
13 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).
14 The configuration procedure is completed and the instrument shows " -.-.-.-. " on both displays. If no other setting is necessary, push the FUNC pushbutton, the display returns to show "COnF".
15 P24 = Alarm 1 action Available only when P9 = "AL1.P", "AL1.d" or "AL1.b". dir = direct action (relay energized in alarm condi- tion) rEV = reverse action (relay de-energized in alarm condition) P25 = alarm 1 stand-by (mask) function Available only when P9 = "AL1.
16 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.
17 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.
18 OPERATIVE MODE 1) Remove the instrument from its case. 2) Set the internal dip switch V101 in closed condi- tion 3) Re-insert the instrument. 4) Switch on the instrument.
19 Pushbutton functionality during operating mode. FUNC = o when the instrument is in "normal display mode" 1) with a brief pressure (<3s) it starts the parameter modification procedure. 2) with a pressure within 3s to 10s it changes the indication on the lower display (see "display function").
20 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.
21 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).
22 When it is desired to switch from LOCK to UNLOCK condition, set a value equal to P17 parameter. When it is desired to switch from UNLOCK to LOCK condition, set a value different from P17 parameter. AL1 Alarm 1 threshold This parameter is available only if P 9 is equal to AL1.
23 Note :When device is working with SMART algorithm the Pb value will be limited by P31 and P32 parameters. HyS 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. ti Integral time This parameter is skipped if Pb=0 (ON/ OFF action).
24 Grd1 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. Grd2 Ramp applied to a decreasing set point changes For other details see Grd1 parameter.
25 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).
26 ERROR LIST SEr Serial interface parameter error. 100 Write EEPROM error. 150 CPU error. 200 Tentative to write on protected memory. 201 - 2xx Configuration parameter error. The two less significant digits shown the number of the wrong parameter (ex.
