D6034 - SIL 3 Switch/Proximity InterfaceG.M. International ISM0215-2
D6034 series must be installed, operated and maintained only by qualified personnel, in accordance to the relevant national/international installation standards.
Failure to properly installation or use of the equipment may risk to damage the unit or severe personal injury.
The unit cannot be repaired by the end user and must be returned to the manufacturer or his authorized representative. Any unauthorized modification must be avoided.
Warning
Operation
The single and dual channel Switch/Proximity Interface, D6034S and D6034D is a high integrity repeater, designed to interface contacts or proximity detectors (EN60947-5-6, NAMUR)
and is suitable for applications requiring SIL 3 level (according to IEC 61508:2010 Ed. 2) in safety related systems for high risk industries.
Field loop integrity and status (line plus contact or proximitor) are continuously and directly monitored, in transparent mode, into the PLC, ESD, DCS using their existing input line,
without requiring an additional channel for line fault detection.
PLC / DCS can detect the following conditions:
0.5 to 1.3 mA Input open condition
2.0 to 6.0 mA Input close condition
0 to 0.4 mA Input fault condition (Line break)
6.5 to 8.0 mA Input fault condition (Short circuit)
These are automatically detected for proximity switches inputs. A “POWER ON” green led for each channel lits when input power is present.
Note: use of voltage free electrical contacts with fault detection enabled (control equipment) requires, near the switch at the end of the line a R1=1 Ktypical (470 to 2 Krange)
resistor in series and a R2=10 ktypical (5 Kto 15 Krange) resistor in parallel to the contacts in order to allow the fault detection circuit to distinguish between a condition of
contact close/open and a line open/short circuit fault.
Installation
D6034 series are Switch/Proximity Detector Interface housed in a plastic enclosure suitable for installation on T35 DIN-Rail according to EN50022, with or without Power Bus or
on customized Termination Board.
D6034 unit can be mounted with any orientation over the entire ambient temperature range.
Electrical connection of conductors up to 2.5 mm² are accommodated by polarized plug-in removable screw terminal blocks which can be plugged in/out into a powered unit without
suffering or causing any damage.
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. D6034S is a single channel model and D6034D 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 “5” and negative at terminal “6”.
For Model D6034S connect positive output of channel 1 at terminal “1” and negative output at “2”.
For Model D6034D in addition to channel 1 connections above, connect positive output of channel 2 at terminal “3” and negative output at “4”.
For Model D6034S, in case of Proximity or Voltage free Contact, connect the wires at terminal “7” for positive and “8” for negative.
For Model D6034D in addition to channel 1 connections above, connect terminal “9” for positive and “10” for negative on channel 2.
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.
Any penetration of cleaning liquid must be avoided to prevent damage to the unit. Any unauthorized card modification must be avoided.
According to EN61010, D6034 series must be connected to SELV or SELV-E supplies.
End of Line Resistor for Contact
Start-up
Before powering the unit check that all wires are properly connected, particularly supply conductors and their polarity, input and output wires. Check conductors for exposed wires that
could touch each other causing dangerous unwanted shorts. Turn on power, the “power on” green leds must be lit output condition must be in accordance with condition of the
corresponding input line. If possible close and open input lines one at time checking the corresponding reflected current output to be correct.
Use of voltage free electrical contacts with fault detection enabled (control equipment) requires, near the switch at the end of the line a 1 Ktypical (470 to 2 Krange) series
connected resistor and a 10 Ktypical (5 Kto 15 Krange) parallel connected resistor in order to allow the fault detection circuit to distinguish between a condition of contact
close/open and a line open/short circuit fault.
