How to demount system DRST-DC

Picture 1:

The device is detached from the DIN rail by moving the bottom lock down.

When front LED flashes red or DRSL-DISPLAY shows AO.ER

DRST-DC is designed with a high safety level. Therefore, the device continuously measures the output current. If "S4-20"

The is selected during configuration, and output current drops to 0 mA, the DRSL-DISPLAY will indicate "AO.ER" and the front LED will turn red. (A 0 mA output can be caused by an open output loop). The error mode can be reset by power cycling the device or stepping through the menu.

Configurable input error indication and input limits

Extended working range

Configurable input error detection

To increase system safety and integrity, users can program a high and low input error detection level. Input signals outside the selected error indication levels will cause the output of the device to go to the programmed error state. The error is indicated in display line 1 as IN.ER and at the same time the backlight flashes.

The two configurable input error detection levels can be set and enabled individually, just as it is possible to individually set the output error indication for each of the two detection levels. This allows users to differentiate process faults, broken input wires, etc.

Available output error states for each of the two detection levels are: UP, DOWN, ZERO and NONE.

Output error indication uses the error states defined by NAMUR NE43 for 4...20 mA output span, and for all other output spans equivalent output error indications are used (see tables on pages 15-16).

Example - 4..20 mA output span and both high and low configurable input error limit enabled with output error indication set to ZERO:

quare root function

The DRST-DC features the possibility of configuring a square root relationship between the input and output. It is possible to use the full square root relationship, or to select a fraction of the square root function, by manually choosing ‘Input min.’ and ‘input max.’ of the square root function, as shown in the figure below:

Low cut-off function:

As a part of the square root function of the DRST-DC is possible to manually configure a low cut-off point. The feature is often used to suppress noise in the system. The low cut off point defines a point where the input/output relationship either changes to a linear relationship or the output is tr

uncated to zero. The two principles are illustrated below:

Configuration / operating the function keys

Documentation for routing diagram.

In general

When configuring the DRST-DC, you will be guided through all parameters and you can choose the settings which fit the application. For each menu there is a scrolling help text which is automatically shown in line 3 on the display.

Configuration is carried out by use of the 3 function keys:

1 will increase the numerical value or choose the next parameter 2 will decrease the numerical value or choose the previous parameter 3 will save the chosen value and proceed to the next menu

When configuration is completed, the display will return to the default state 1.0. Pressing and holding previous menu or return to the default state (1.0) without saving the changed values or parameters.

If no key is activated for 1 minute, the display will return to the default state (1.0) without saving the changed values or parameters.

Further explanations

Password protection: Programming access can be blocked by assigning a password. The password is saved in the device in

order to ensure a high degree of protection against unauthorised modifications to the configuration. Default password 2008 allows access to all configuration menus.

Signal error indication via display front DRSL-DISPLAY & DRST-CM

Signal error is displayed as LO.ER (see table page 19). Input signals outside the selected range are displayed as IN.LO indicating low input signal or IN.HI indicating high input signal (see table page 19). Error indication is displayed in line 1 as text and at the same time the backlight flashes. A flashing bullet in line 4 is indicating correct functioning of DRSL-DISPLAY & DRST-CM.

3 will return to the

Signal error indication without display front

Status of the unit can also be read from the red/green LED in the front of the device.

Green flashing LED 13 Hz indicates normal operation. Green flashing LED 1 Hz indicates configurable input limit error. Steady green LED indicates internal error. Steady red LED indicates fatal error.

Advanced functions

The unit gives access to a number of advanced functions which can be reached by answering “Yes” to the point “ADV.SET”.

Memory (MEM): In the memory menu you can save the configuration of the device in the DRSL-DISPLAY & DRST-CM, and then move the DRSL-DISPLAY & DRST-CM onto another device of the same type and download the configuration in the new device.

Display setup (DISP): Here you can adjust the brightness contrast and the backlight. Setup of TAG numbers with 6 alphanumerics. Selection of functional readout in line 3 of the display - choose between readout of analogue output or tag no.

Two-point process calibration (CAL): The device can be process-calibrated in 2 points to fit a given input signal . A low input signal (not necessarily 0%) is applied and the actual value is entered via DRSL-DISPLAY & DRST-CM. Then a high signal (not necessarily 100%) is applied and the actual value is entered via DRSL-DISPLAY & DRST-CM. If you accept to use the calibration, the device will work according to this new adjustment. If you later reject this menu point or choose another type of input signal the device will return to factory calibration.

Process simulation function (SIM): In the menu point “EN.SIM” it is possible to simulate an input signal by means of the arrow keys and thus control the output signal up or down. You must exit the menu by pressing 3 (no time-out). The simulation function exits automatically, if the DRSL-DISPLAY & DRST-CM is detached.

Password (PASS): Here you can choose a password between 0000 and 9999 in order to protect the unit against unauthorized modifications to the configuration. The unit is delivered default without password.

Page 23

Language (LANG): In the menu ”LANG” you can choose between 7 different language versions of help texts that will appear in the menu. You can choose between UK, DE, FR, IT, ES, SE and DK.

Output function (OFUN): Here the output characteristics can be set to either Direct (DIR) or Inverted (INV) function. Output type and range are set in the normal programming menu. If the selected output range is starting at zero, V-curved output function (VFUN) can also be selected. The output characteristics will then be 100-0-100% on the basis of a linear 0-100% input signal.

Square root and low cut-off function (IFUN): Here it is possible to choose a square root relationship between input and output and decide which section of the square root function that has to be used. The function includes a low cut-off point for limiting "small" input signals. Cut-off type and cut-off value are also selected in this menu point.

Auto diagnostics

The device performs an advanced auto diagnosis of the internal circuits - check tables on page 19.
