**3 How to Dismantle DRST-UR** ~~wo~~
## **Section 3.1 - How to Dismantle DRST-UR**
First, remember to demount the connectors with hazardous voltages. **Picture 1:** Detach the device from the DIN rail by lifting the bottom lock.
## **Section 3.2 - When front LED lights red / display shows AO.ER**
Omega DRST-UR is designed as a SIL 2 device with a high safety level. Therefore, a continuous measurement of the outgoing current is carried out on a 4...20 mA and 20...4 mA output signal. If the current output signal is different from the internal calculated output value or the current output is 0 (due to e.g. an open circuit breakage), an error mode switches on the red front LED and disables the relays. This function is not a default option but must be actively selected via the programming menu (S4-20 & S20-4).
The error mode can only be reset by switching off and then switching on the supply voltage to the device.

> **CONFIGURATION/OPERATING THE FUNCTION KEYS 13**
## **Section 13.1 - Configuration / operating the function keys**
Documentation for routing diagram.
## **In general**
When configuring the DRST-UR, 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:
- will increase the numerical value or choose the next parameter
- will decrease the numerical value or choose the previous parameter
- OK will accept 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 will return to the previous menu or return to the default state (1.0) without saving the changed OK 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**
**Fast setpoint adjustment and relay test:** These menus allow you to make a quick setpoint change and relay test when the FastSet menu is activated. This function can only be activated when the relays are set for setpoint function and are controlled by a setpoint.
Pressing and simultaneously will activate a relay test and change the state of the relay.
Pressing will save the setpoint change. OK
Holding down for more than 1 second will return the unit to the default state without saving the setpoint change. OK
- **Password protection:** Programming access can be blocked by assigning a password. The password is saved in the transmitter in order to ensure a high degree of protection against unauthorised modifications to the configuration. Default password 2008 allows access to all configuration menus.
**21**
**13 Signal & sensor error display**
## **Section 13.1 - Signal and sensor error info via display front DRSL-DISPLAY**
Sensor error (see limits in the table) is displayed as SE.BR (sensor break) or SE.SH (sensor short). Signals
- outside the selected range (not sensor error, see table for limits) are displayed as IN.LO indicating low input signal or IN.HI indicating high input signal. The error indication is displayed in line 3 as text and at the same time the backlight flashes. Line 4 of the display is a status line which displays status of relay 1 and relay 2, COM (flashing bullet) indicating correct functioning of **DRSL-DISPLAY** and arrow up/down which indicates tendency readout of the input signal. If the figure 1 or figure 2 flashes, the unit has detected that the setpoint has been exceeded and that the relay is in “delay” mode. When the delay time has passed and the relay makes/breakes, the relay sign either displays or disappears.
## **Signal and sensor 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 sensor error. Steady red LED indicates internal error.
## **Relay functions**
6 different settings of relay function can be selected.
**Setpoint:** The unit works as a single limit switch **Window:** The relay has a window that is defined by a low and a high setpoint. On both sides of the window the relay has the same status. Error function: The relay is activated by sensor error. **Power:** The relay is activated as long as the power is on. **Off:** The relay is deactivated. **Latch:** The relay is latched. Only valid for setpoint and window function.
**Increasing/decreasing:** The relays can be set to activate at increasing or decreasing input signal.
**Delay:** An ON and an OFF delay can be set on both relays in the range 0...3600 s.
**Hysteresis:** 0.0...100.0%.
**22**
**Latch 15**
## **Latch**
When the setpoint is exceeded the relay outputs enters an alarm state. The latch function of the DRST-UR will hold the relays in this state until the function is deactivated manually. The latch function can be applied when the relay function setpoint or window is selected.
- The latch function can be selected separately for each relay output. If the configuration is copied from one device to another by way of the **DRSL-DISPLAY** , the latch function must be reconfigured.
- The latch function activates and holds the relays when the input signal rises above or falls below the selected setpoints and the relay action has been selected as increasing or decreasing.
The window function is selected by choosing ”window” in the menu and defining a high and a low setpoint.
- It can be selected for each relay contact whether the contact is open or closed inside the window. This selection is made in the menu R1.cont and R2.cont.
- The setpoint function is selected by choosing ”setpoint” in the menu and entering the desired limit. The device then works as a single limit switch.
- An activated relay means that the contact is closed if the contact function ”normally open” is selected, and the contact is open if the contact function ”normally closed” is selected.
- The delay time for activation and deactivation can be set independently of each other in the menus ON.DEL and OFF DEL respectively.
- If the relay function ”Error” is active, the relay will latch when a sensor error occurs and will not be deactivated automatically when the sensor error is rectified.
- The relay can only be deactivated by an operator and only when the normal conditions for deactivation are met. If the input signal still has a value that will activate the relay, the relay will latch again.
- See the graphic depiction of the setpoint and window functions on pages 34 and 35.
**23**
**15 Latch**
## **Section 15.1 - Manual deactivation of the latch function**
If the relay outputs are activated and thereby latched, it will be indicated in the display. The backlight flashes and the scrolling help text tells you how to deactivate the output. Manual deactivation is carried out by way of the front buttons on the **DRSL-DISPLAY** . Use and to navigate in the menu and to validate your selection. OK If the password protection has been activated, the password must be entered in order to access the deactivation menu. See the menu structure on page 29.
## **Section 15.2 - Advanced functions**
The device gives access to a number of advanced functions which can be reached by answering “Yes” to the point “adv.set”.
## **Section 15.3 - Display setup:**
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.
## **Section 15.4 - Two-point process calibration:**
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** . Then a high signal (not necessarily 100%) is applied and the actual value is entered via **DRSL-DISPLAY** . 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.
## **Section 15.5 - Process simulation function:**
If you agree to the 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. When you finalise the point with , the device returns to normal mode. OK The following point allows you to activate relay 1 and relay 2 by means of the arrow-keys up/down. You must exit the menu by pressing (no time-out).OK
## **Section 15.6 - Password:**
Here you can choose a password between 0000 and 9999 in order to protect the device against unauthorised modifications to the configuration. The device is delivered default without password. If you have locked the device with a password by mistake, you can always open the menu by using the master password 2008.
## **Section 15.7 - Language:**
In the menu ”lang.setup” 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.
**24**
**Auto Diagnosis 16**
## **Section 16 - Auto diagnosis**
The device performs an advanced auto diagnosis of the internal circuits. The following possible errors can by displayed in the front unit **DRSL-DISPLAY** . CJ.ER - CJC sensor defect or CJC temperature outside range FL.ER - Flash error AO.ER - No load on the current output (only for S4...20 mA / S20...4 mA) NO.CO - Connection error IN.ER - Error levels on input TY.ER - Configuration in **DRSL-DISPLAY** does not match this product type
**25**
**17 Units/Safety/Memory**
## **Section 17.1 - Selection of units**
After choosing the input signal type you can choose which process units should be displayed in text line 2 (see table). By selection of temperature input the process value is always displayed in Celsius or Fahrenheit. This is selected in the menu point after selection of temperature input.
## **Section 17.2 - Safety readback**
When the device is delivered with default configuration, the SIL function is disabled. The safety readback function (loop surveillance) can be selected in the menu O.RANGE, thus enabling the device to run in SIL mode. In order to enable the SIL functionality, the menu item S4...20 mA must be selected. Please note, however, that when safety readback is enabled, a sensor error will be indicated as an error on the analogue output signal.
## **Section 17.3 - CJC**
In the CJC menu you can choose between CJC connector and internal cold junction compensation. The CJC connecter must be ordered separately.
## **Section 17.4 - Memory**
In the memory menu you can save the configuration of the device in the **DRSL-DISPLAY** , and then move the **DRSL-DISPLAY** onto another device of the same type and download the configuration in the new device.
