Demounting

Section 3.1 - How to demount DRST-UN

First, remember to demount the connectors with hazardous voltages.
Picture 1: Detach the device from the DIN rail by lifting the bottom lock.

When front LED lights red / display shows AO.ER

PR DRST-UN 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.
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 menus

Section 10.3 - Signal and sensor error info (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 COM (flashing
bullet) indicating correct functioning of DRSL-DISPLAY, and arrow up/down which
indicates tendency readout of the input signal.

Section 10.4 - Signal and sensor error info (no display)

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 green LED indicates internal error.
Steady red LED indicates fatal error.

Section 10.5 - Advanced Functions

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

Section 10.6 - Display setup

Here you can adjust the brightness contrast and the backlight. Setup of TAG number
with 6 alphanumerics. Selection of functional readout in line 3 of the display - choose
between readout of analogue output or TAG number.

Section 10.7 - Two-point process calibration

The unit 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 DRSL­DISPLAY. 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 unit will work
according to this new adjustment. If you later reject this menu point or choose another
type of input signal the unit will return to factory calibration.

24

Section 10.8 - Process simulation function

If you say ”yes” 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 unit returns to normal mode.

TY.ER - Configuration in DRSL-DISPLAY/DRST-CM does not match this

product type

Section 10.12 - Selection of units

After choosing the input signal type you can choose the process units which will 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 10.13 - 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.
