Safety Function and Failure behavior:
D1020 is considered to be operating in Low Demand mode, as a Type A module, having Hardware Fault Tolerance (HFT) = 0.
The failure behaviour of the D1020 S and D1020D modules (when the output current range is 4 to 20 mA) is described by the following definitions:
□ Fail-Safe State: it is defined as the output going to Fail Low.
□ Fail Safe: failure mode that causes the module / (sub)system to go to the defined Fail-Safe state without a demand from the process.
□ Fail Dangerous: failure mode that does not respond to a demand from the process (i.e. being unable to go to the defined Fail-Safe state) or deviates the output current by more
than 5% full span (+/- 0.8 mA).
□ Fail High: failure mode that causes the output signal to go above the maximum output current (> 20 mA). This failure mode is considered as a Dangerous Undetected failure.
□ Fail Low: failure mode that causes the output signal to go below the minimum output current (< 4 mA). This failure mode is considered as a Safe Undetected failure.
□ Fail “No Effect”: failure mode of a component that plays a part in implementing the Safety Function but that is neither a safe failure nor a dangerous failure. When calculating
theSFF, this failure mode is not taken into account.
□ Fail “Not part”: failure mode of a component that is not part of the Safety Function but is part of the circuit diagram and is listed for completeness. When calculating the SFF, this
failure mode is not taken into account.
The 2 channels of D1020D module could be used to increase the hardware fault tolerance, needed for a higher SIL of a certain Safety Function, as they are they are completely inde-
pendent each other, not containing common components. In fact, the analysis results got for D1020S (single channel) are also valid for each channel of D1020D (double channel).
Failure rate date: taken from Siemens Standard SN29500.
Description:
The module is powered by connecting 24 Vdc power supply to Pins 3 (+ positive) - 4 (- negative) for Channel 1 and Pins 7 (+ positive) - 8 (- negative) for Channel 2.
The greens LED are lit in presence of each power supply line.
The current input signals from the Safety PLC outputs are applied to Pins 1-2 (In 1 - Ch.1) and Pins 5-6 (In 2 - Ch.2).
The source output currents for I/P converters are applied to Pins 14-15 (for Channel 1) and Pins 10-11 (for Channel 2).

Testing procedure at T-proof
The proof test must be performed to reveal dangerous faults which cannot be otherwise detected. This means that it is necessary to specify how dangerous undetected faults, which
have been noted during the FMEDA analysis, can be revealed during the proof test.
The Proof Test 1 consists of the following steps:
This test will detect approximately 70% of possible Dangerous Undetected failures in the repeater.
The Proof Test 2 consists of the following steps:
This test will detect approximately 99% of possible Dangerous Undetected failures in the repeater.
Steps Action
1Bypass the Safety-related PLC or take any other appropriate action to avoid a false trip.
2Provide a 20 mA control signal to the driver to open/close the valve and verify that the valve is open / closed. This test is for voltage compliance
problems, such as a loop power supply voltage or increased wiring resistance, and for other possible failures. It requires, however, that the positioned
has already been tested without the driver and does not contain any dangerous undetected failures.
3Provide a 4mA control signal to the driver to close/open the valve and verify that the valve is closed /open. This test is for possible quiescent current
related failures. It requires, however, that the positioner has already been tested without the driver and does not contain any dangerous undetected
failures
4Restore the loop to full operation.
5Remove the bypass from the Safety-related PLC or restore normal operation.
Steps Action
1Bypass the Safety-related PLC or take any other appropriate action to avoid a false trip.
2Perform steps 2 and 3 of the Proof Test 1.
3Perform a two-point calibration of the positioner (i.e. 4 mA and 20 mA) and verify that the output current from the module is within the specified accuracy.
This test requires, however, that the positioner has already been tested without the driver and does not contain any dangerous undetected failures.
4Restore the loop to full operation.
5Remove the bypass from the Safety-related PLC or restore normal operation.

D1020 isolates and transfers a 0/4-20 mA signal from a controller located in Safe Area/Non Hazardous Locations to an I/P converter, displays or similar equipment located in Hazardous
Area/Hazardous Locations. The circuit allows bi-directional communication signals for smart/hart converters. In the 4-20 mA input range, a field open circuit presents a high impedance to
the control device. A “POWER ON” green led lits when input power is present.
Installation
D1020 series are powered isolating driver smart/hart compatible housed in a plastic enclosure suitable for installation on T35 DIN Rail according to EN50022.
D1020 unit can be mounted with any orientation over the entire ambient temperature range, see section “Installation in Cabinet” and "Installation of Electronic Equipments in Cabinet"
Instruction Manual D1000 series for detailed instructions. Electrical connection of conductors up to 2.5 mm² are accommodated by polarized plug-in removable screw terminal blocks
shich can be plugged in/out into a powered unit without suffering or causing any damage (for Zone 2 or Division 2 installations check the area to be nonhazardous before
servicing). The wiring cables have to be proportionate in base to the current and the length of the cable. On the section “Function Diagram” and enclosure side a block diagram identifies
all connections. Identify the number of channels of the specific card (e.g. D1020S is a single channel model and D1020D is a dual channel model), the function and location of each
connection terminal using the wiring diagram on the corresponding section, as an example:
Connect 24 Vdc power supply positive at terminal “3” and negative at terminal “4”.
For Model D1020D connect 24 Vdc power supply positive at terminal “7” and negative at terminal “8” for channel 2.
For Model D1020S connect positive input of channel 1 at terminal “1” and negative input at “2”.
For Model D1020D in addition to channel 1 connections above, connect positive input of channel 2 at terminal “5” and negative input at “6”.
For Model D1020S connect output at terminal “14” for positive and “15” for negative.
For Model D1020D in addition to channel 1 connections above, connect terminal “10” for positive and “11” for negative on channel 2.
Intrinsically Safe conductors must be identified and segregated from non I.S. and wired in accordance to the relevant national/international installation standards
(e.g. EN/IEC60079-14 Electrical apparatus for explosive gas atmospheres - Part 14: Electrical installations in hazardous areas (other than mines), BS 5345 Pt4, VDE 165,
ANSI/ISA RP12.06.01 Installation of Intrinsically Safe System for Hazardous (Classified) Locations, National Electrical Code NEC ANSI/NFPA 70 Section 504 and 505,
Canadian Electrical Code CEC), make sure that conductors are well isolated from each other and do not produce any unintentional connection.
The enclosure provides, according to EN60529, an IP20 minimum degree of mechanical protection (or similar to NEMA Standard 250 type 1) for indoor installation, outdoor installation
requires an additional enclosure with higher degree of protection (i.e. IP54 to IP65 or NEMA type 12-13) consistent with the effective operating environment of the specific installation.
Units must be protected against dirt, dust, extreme mechanical (e.g. vibration, impact and shock) and thermal stress, and casual contacts. If enclosure needs to be cleaned use only a
cloth lightly moistened by a mixture of detergent in water. Electrostatic Hazard: to avoid electrostatic hazard, the enclosure of D1020 must be cleaned only with a damp or
antistatic cloth. Any penetration of cleaning liquid must be avoided to prevent damage to the unit. Any unauthorized card modification must be avoided. According to EN61010, D1020
series must be connected to SELV or SELV-E supplies.
Start-up
Before powering the unit check that all wires are properly connected, particularly supply conductors and their polarity, input and output wires, also check that Intrinsically Safe conductors
and cable trays are segregated (no direct contacts with other non I.S. conductors) and identified either by color coding, preferably blue, or by marking. Check conductors for exposed
wires that could touch each other causing dangerous unwanted shorts. Turn on power, the “power on” green led must be lit, output signal should be corresponding to the input from the
controller. If possible change the input value and check the corresponding Hazardous Area output.

Calibration instruction and Troubleshooting
In case a calibration check or readjustment is necessary the following equipment is required:
Set power supply (PS) at 24.0 V at terminals 3 (+) and 4 (-), the calibrator (CAL) in the function “mA” 20 mA range at terminals 1 (+) and 2 (-), the multimeter (V1) for the reading in
DC supply 30 V range at terminals 1 (+) and 2 (-), the multimeter (DMM) for the reading in DC supply 20 mA range at terminals 14 (+) and 15 (-).
Execute the next test to verify D1020S unit channel or execute it twice to verified both D1020D unit channels.
Verify that green led on the front panel is ON.
Connect the unit as shown below:
If the power ON Led is off, check supply voltage, polarity and wiring.
Set calibrator (CAL) at 4.000 mA and verify that the output current, read by multimeter (DMM), is correspondent with a maximum deviation presented in the section “Technical Data”.
Set calibrator (CAL) at 20.000 mA and verify that the output current, read by multimeter (DMM), is correspondent with a maximum deviation presented in the section “Technical Data”.
Set calibrator (CAL) at 20.000 mA and power supply (PS) at 20.0 V; verify that multimeter (V1) reads input voltage as presented in the section “Technical Data”.
If the maximum deviation is exceeded, repeat the board calibration and proceed in the following way:
Set the calibrator (CAL) at 20.000 mA and regulate the current, read by multimeter (DMM), by turning the span trimmer of the unit (see “Configuration” section) until reading 20.000
mA ± 5 µA value.
To execute a linearity test: set the calibrator (CAL) at 4.000, 8.000, 12.000, 16.000, 20.000 mA and verify current output is correspondent with
a maximum deviation presented in the section “Technical Data”.
