Mounting Requirements

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.

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).

OPERATING MODE

1) Remove the instrument from its case.

2) Set switch V101 to the closed condition.

3) Re-insert the instrument in its case.

4) Switch on power to the instrument.

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.

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.

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.

20

-

-

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.

-

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 pressing s

+ 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.

Error Messages

Overrange, Underrange, and Sensor Break

This device is capable of detecting process variable faults (OVERRANGE, UNDERRANGE or SENSOR

BREAK). When the process variable exceeds the span limits established by configuration parameter P1, an

OVERRANGE condition will appear as:

An UNDERRANGE condition will appear as:

Output action on Over/Underrange

When P33 = 0, the following conditions will occur:

If an OVERRANGE condition is detected, OUT 1

turns OFF (if reverse acting) or ON (if direct acting).

If an UNDERRANGE condition is detected, OUT 1 turns ON (if reverse acting) or OFF (if direct acting).

When P33 is not zero and an out of range condition is detected, the instrument operates in accordance with parameters P33 and P34.

The sensor break can be signalled as:

- for TC/mV input: OVERRANGE or UNDERRANGE selected by a solder jumper.

- for RTD input: OVERRANGE

- for mA/V input: UNDERRANGE

Note

: On the mA/V input, sensor break can be detected only when the range selected has a zero elevation (4-20 mA, 1-5 V, or 2-10 V).

On the RTD input a special test is provided to signal an

OVERRANGE when input resistance is less than 15 ohms (short circuit sensor detection).

28

Start-Up

On powerup, the instrument performs a self-diagnostic test. When an error is detected, the lower display shows an “Err” indication while the upper display shows the code of the detected error.

Setpoint Pattern -- Regions Description:

1) Standby Region: The instrument operates as an indicator. Power output is off and alarms are in no alarm status. Range: 0 to 99 h 59'.

2) Wait Region: In this region the power out is off and alarms are in no alarm status. The time duration is programmed by "wait time"

parameter. Upper display shows the process variable while the lower display shows, flashing, the time to reach the end of this region.

Range: 0 to 99 h 59'.

3) Ramp to SPx Regions: At the beginning of this region the instrument aligns the operating setpoint to the actual measured value and then it will start ramping toward SPx (SP1 or SP2).
