Notes • • • 4 For supply connections use No 16 AWG or larger wires rated for at least 75 °C. Use copper conductors only. Class 2 wiring must be separated a minimum of 1/4 inch from any Class 1 conductors. Mounting Requirements Proceed as follows: 1) Insert gasket on the instrument case. 2) Insert instrument in control panel. 3) Pushing the instrument against the panel, insert the mounting bracket. 4) With a screwdriver, turn the screws with a torque between 0.3 and 0.4 Nm (2.6 to 3.5 lfb-in). Select a location for instrument mounting where minimum vibrations are present and the ambient temperature is within 0 and 50°C (32 and 122°F). The instrument can be mounted on a panel up to 15 mm thick (.59") with a square cutout of 45 x 45 mm (1.77 x 1.77"). Surface texture of the panel must be better than 6.3 µmm (248 microinches). The instrument is shipped with rubber panel gasket (50 to 60 Sh). To assure IP65 and NEMA 4 protection, insert the panel gasket between the instrument and panel as shown.

P22 = OFFSET applied to the measured value Used to apply a constant OFFSET throughout readout range (not used for linear inputs). - For readout ranges with a decimal place, P22 can be set with keys from -19.9 to 19.9. - For readout ranges without a decimal place, P22 can be set with keys from -199 to 199. Re a dou t R e al C u rve P22 NOTE: A dju sted C u rve P27 = Minimum value of the proportional band calculated by autotuning Can be set with keys from 1.0% to P26. P28 = Minimum value of the integral time calculated by autotuning Can be set with keys from 20 sec. (0.20) to 2 minutes (2.00). P29 = Device status at instrument start-up 0 = The instrument starts in the standby mode. All outputs will be off, and the lower display shows "off." WARNING: When a "hot start" occurs (i.e. after a power failure), program execution will be aborted and the instrument will restart in standby mode. 1 = The instrument starts in the same mode it was in prior to shutdown. In p ut NOTES: A) If the instrument was ramping (region 2 or 4), it aligns the setpoint to the measured value and then restarts the ramp (up or down) by the programmed gradient. P23 = Control output maximum rate of rise Can be set with keys from 1% to 10% of the output per second. Above 10%, the display will show "InF," meaning that no ramp is used. 16 B) If the instrument was performing a soak (region 1, 3 or 5), it divides the soak time into quarters and restarts from the beginning of the quarter that was being executed prior to shutdown. P30 = Integral pre-load Can be set with keys from 0% to 100% of the output range. P31 = Timeout selection This parameter sets the duration of the timeout used by the instrument during the operating mode. tn. 10 = 10 seconds tn. 30 = 30 seconds Default Configuration Parameters The configuration parameters can be loaded with predetermined default values. These are the settings loaded into the instrument prior to shipment from the factory. To load the default values proceed as follows: a) Internal switch V101 must be open. b) The upper display will show: c) Press the t key; the lower display will show the firmware version. P32 = Digital filter on the measured value noFL. = No filter FLtr = Filter enabled: A first order digital filter with a time constant equal to: 4 seconds for TC and RTD inputs 2 seconds for linear inputs P33 = Conditions for output safety value 0 = No safety value (default). 1 = Safety value applied when an overrange or underrange condition is detected. 2 = Safety value applied when an overrange condition is detected. 3 = Safety value applied when an underrange condition is detected. P34 = Output safety value This parameter is skipped if P33 = 0. This value can be set from 0% to 100%. (This completes the configuration procedure. The display should show “COnF.”) 17 d) Hold down thet key and press thes key; the display will show: e) Press the s key to select table 1 (European) or table 2 (American) default parameters; the display will show: f) Press the FUNC key; the display will show: This indicates that the loading procedure has been initiated.

Display Function The upper display shows the measured value while the lower display shows: - OFF when the instrument is in standby mode (all outputs off, programmer not running) - The time remaining during the initial delay (region 1) - The setpoint during a ramp - The time remaining during a soak (The above conditions are the “normal display mode.”) It is possible to change the information on the lower display as follows: - Press the FUNC key for 3 seconds. The lower display will show " H. " followed by the OUT 1 power value (from 0% to 100%). - Press the FUNC key again. The display will return to the "normal display mode." If no keys are pressed within the timeout period (see P31), the display will automatically return to the normal display mode. In order to keep the desired information on the lower display, press s or t key to stop the timeout. To return to the normal display mode, press the FUNC key again. Indicators °C Lit when the process variable is shown in degrees Celsius. °F Lit when the process variable is shown in degrees Fahrenheit. AT Flashes during autotuning (Smart AT). Lit when autotuning is active. 19 Lit when Output 1 is ON. Lit when Output 2 (used as event output) is ON or Alarm 1 is ON. Lit when Alarm 2 is ON or when Output 3 is used as an "End of cycle" logic output. Other functions are shown by decimal points: A) When the decimal point to the right of the least significant digit of the lower display is lit, the instrument is using SP2. B) When the decimal point to the right of the most significant digit of the lower display is flashing, the instrument is in the manual mode. C) When the decimal point to the right of the least significant digit of the upper display is lit: - The program is running or, - The instrument is performing the 2 initial regions ("wait" and "ramp to SP1") before operating as a controller. When the decimal point to the right of the least significant digit of the upper display is flashing: - The tracking or guaranteed soak functions are delaying program execution. - An out of range condition has been detected. Operating Key Functions FUNC = - During parameter modification the new setting of the selected parameter is stored and the next parameter is displayed (in increasing order). - During program execution or when operating as a controller (without program), pressing the FUNC key for more than 3 seconds will show " H. " on the lower display, followed by the OUT 1 power (from 0 to 100%). Press the FUNC key again, and the display will return to the "normal display mode." RUN = - With P9 = 0 and the instrument in standby mode, press RUN for 1 second to start program execution. - With P9 = 0, press for 5 seconds to abort the program. - During parameter modification, RUN is used to scroll back the parameters without memorizing the new setting. s = - Increases the value of the selected parameter during parameter modification. - Allows direct access to the setpoint when the instrument is operating as a controller. - Increases the output when the instrument is in manual mode. t = - Decreases the value of the selected parameter during parameter modification. - Allows direct access to the setpoint when the instrument is operating as a controller. - Decreases the output when the instrument is in the manual mode. s + FUNC = Toggles between standby and manual mode. s + FUNC or t + FUNC = Increases or decreases the value of the selected parameter at a faster rate. s and t = When autotuning (Smart AT) is disabled, the up and down arrow keys are used to start the default parameter loading procedure. NOTE: A 10 or 30 second timeout (P 31) can be selected for parameter modification. If no keys are pressed during this time period, the instrument automatically goes to the “normal display mode” and the last parameter is NOT changed. 20 Operating Modes The 7SP is a controller/programmer. This instrument can be operated in 3 modes: - MODE A “Standby” The device operates as an indicator; the power out is OFF and the alarms are in the no alarm condition. The upper display shows the process variable while the lower display shows “OFF.” The Manual mode (MODE C) can be enabled by pressing the s + FUNC keys. - MODE B “Run” This mode can be enabled by pressing the “RUN” key or by closing the external contact for more than 1 second (see P9). The RUN LED will be lit. The device operates as follows: B.1) As a Controller: With the SP1 soak time set to "infinite," the instrument performs the first 2 regions ("Wait" and "Ramp to SP1") and then operates as a standard controller. Note: When the instrument operates as a controller it is possible to modify the operating setpoint (SP1) using the direct access to the setpoint function or by selecting the SP1 parameter and entering a new setting. When the instrument reaches the SP1 setting, it turns OFF the RUN LED. B.2) As a Controller/Programmer. The program has 5 regions. Refer to "Programmer Worksheet": 1. WAIT REGION The power output is OFF and the alarms are in the no alarm condition. The time duration of this region is programmed using the “dELY” parameter. The upper display shows the process variable while the lower display flashes the time to reach the end of this region. - - 2. RAMP to SP1 The instrument aligns the setpoint to the actual measured value and starts ramping towards SP1. The slope of this ramp is programmed by the “Grd1” parameter. The tracking function may be active during the ramp (see P14 and P15). The upper display shows the process variable while the lower display shows the final setpoint (SP1). 3. SOAK at SP1 The guaranteed soak feature may be active (see P16). The upper display shows the process variable while the lower display shows the time to reach the end of this region. Use the "tin1" parameter. 4. RAMP to SP2 The instrument starts ramping from SP1 to SP2. The slope of this ramp is programmed by the “Grd2” parameter. During the ramp the tracking function may be active (see P14 and P15). The upper display shows the process variable while the lower display shows the final setpoint (SP2). The "SP2" LED will be lit. 5. SOAK at SP2 The guaranteed soak feature may be active (see P16). The upper display shows the process variable while the lower display shows the time to reach the end of this region. See parameter "tin2." The "SP2" LED will be lit. When this region is completed, two different situations may occur: If no "repeats" have been programmed and P10 does not = 5, the device returns to standby mode. The "rPt" parameter is used to program the number of repeats. If one or more repeat has been programmed, the next cycle starts from region 2 (Ramp to SP1) or from region 1 (Wait) according to the "dELY" (either ON/ OFF) parameter setting. 21 - MODE C "Manual" Manual mode can be enabled only from the standby mode by pressing the s + FUNC keys. When the instrument is in manual mode the lower display shows "n." followed by the OUT 1 power (from 0 to 100%). The decimal point after the most significant digit of the lower display will be flashing. The power output can be modified using the s and t keys. By pressings + FUNC keys again, the device returns to Standby. Note: If a shutdown occurs while in the manual mode, the instrument will restart in the Manual mode with the same power settings. 22 Tem p eratu re SP# S T EP S tep N um be r 1 W ait T im e (h h:m m ) E nd S etpo int 1 R ate o f Ra m p to S P 1 S o ak T im e (hh :m m ) E nd S etpo in t 2 R ate of R am p to S P 2 S oa k T im e (h h :m m ) N u m be r o f P rog ra m R ep etitio n s W ait T im e o n Re petition 23 2 3 4 5 6 7 NOTE: 1) Autotuning enabling/disabling can be protected by password (see P25). 2) During the first region (WAIT) the autotuning LED will be OFF.

Flashes when the value is out of range or the tracking or guaranteed soak functions suspend program execution. Lit when autotuning (Smart AT) is enabled. When the instrument operates as a controller the RUN LED will be OFF. Autotuning (Smart AT) Autotuning is used to automatically optimize the control action. To enable autotuning, press the FUNC key until the “Snrt” parameter is shown. Press the s or t key to set the display to “On” and then press the FUNC key. The AT LED will turn on. When autotuning is enabled, it is not possible to display or to modify the control parameters (Pb, TI and Td). To disable autotuning, press the FUNC key until the “Snrt” parameter appears. Press the s or t key to set the display to “OFF” and press the FUNC key again. The AT LED will turn off. Once autotuning is turned off, the instrument retains the calculated control parameters, but allows the parameters to be modified. 24 Operating Parameters Press and hold the FUNC key (for about 3 seconds). The lower display will show the parameter code and the upper display will show the setting or status (ON or OFF) of the selected parameter. Pressing the s or t key to select a setting. NOTES: 1) Manual reset of the alarms is active. 2) When P24 = ON and the instrument is in manual or standby mode, parameter modification is limited by the status of the Software key (see parameter "nnn") and autotuning (Smart AT). 3) When P24 = ON and the instrument is operating as a controller, it is possible to display but not to modify the following parameters: dELY (hh.mm), EV1, SP1, Grd1, EV2, tIn1, EV3 (parameters SP2, Grd2, EV4, tIn2, EV5, rPt and dELY (ON/OFF) will be skipped). Display and modification of the remaining parameters is limited by the status of the Software key (see parameter "nnn" ) and autotuning. 4) When P24 = ON and the instrument is in the RUN mode, it is possible to display but not to modify the following parameters: dELY (hh.mm), EV1, SP1, Grd1, EV2, tIn1, EV3, SP2, Grd2, EV4, tIn2, EV5, rPt and dELY (ON/OFF). Modification of the remaining parameters is limited by the status of the Software key (see parameter "nnn") and autotuning.
