D1030 - SIL 2 Switch / Proximity Detector Repeater Relay Output G.M. International ISM0008-17
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, status and fault led on each channel must be in accordance
with condition of the corresponding input line. If possible close and open input lines one at time checking the corresponding status and fault leds condition as well as output to be correct.
Installation
D1030 series are switch/proximity detector repeaters housed in a plastic enclosure suitable for installation on EN/IEC60715 TH 35 DIN-Rail.
D1030 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 which 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 and configuration DIP switches.
Identify the number of channels of the specific card (e.g. D1030S is a single channel model and D1030D 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 D1030S connect common relay contact output of channel 1 at terminal “1”, normally closed contact at “8” and normally opened contact at “2”.
For Model D1030D connect common relay contact output of channel 2 at terminal “5”, normally closed contact at “7” and normally opened contact at “6”.
For Model D1030S connect proximity sensor or voltage free contact at terminal “13” for positive and “14” for negative.
For Model D1030D in addition to channel 1 connections above, connect terminal “15” for positive and “16” 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.
Connect SPDT relay contacts checking the load rating to be within the contact maximum rating (2 A, 250 V, 500 VA 80 W resistive load).
The enclosure provides, according to EN/IEC 60529, an IP20 minimum degree of protection. The equipment shall only be used in an area of at least pollution degree 2, as defined in EN/
IEC 60664-1. For hazardous location, the unit shall be installed in an enclosure that provides a minimum ingress protection of IP54 in accordance with EN/IEC 60079-0, that must have a
door or cover accessible only by the use of a tool. 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 D1030 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, D1030 series must be connected to SELV or SELV-E supplies.
Relay output contact must be connected to loads non exceeding category I, pollution degree I overvoltage limits.
Warning: de-energize main power source (turn off power supply voltage) and disconnect plug-in terminal blocks before opening the enclosure to avoid electrical shock
when connected to live hazardous potential.
Operation
D1030 accepts as an input from Hazardous Area/Hazardous Locations a proximity sensor or voltage free electrical contact and repeats their status to Safe Area/Non Hazardous
Locations by a voltage free SPDT relay contact. Presence of supply power and status of output (energized or de-energized), as well as integrity or fault condition of sensor and
connecting line are displayed by signaling LEDs (green for power, yellow for status and red for fault condition).
D1030D (dual channel type) has two independent input channels and actuates the corresponding output relay SPDT contact; two actuation modes can be independently DIP switch
configured for each input channel: Normally open input / Normally energized relay or Normally close input / Normally energized relay.
Contact or proximity sensor and its connection line short or open circuit fault detection is also DIP switch configurable. Fault detection can be enabled (in case of fault de-energizes the
corresponding output channel relay and turns ON the fault LED) or be disabled (in case of fault the corresponding output channel relay repeats the input line open or close status as
configured). D1030S (single channel type) has one input channel and two output relays; the unit has two DIP switch configurable operating modes:
A) Input channel actuates in parallel output relays SPDT contacts (providing a DPDT type of output). Relays actuation can be independently configured for each output in two modes:
Normally open input / Normally energized relay or Normally close input / Normally energized relay
B) Input channel actuates output relay (A) SPDT contacts configurable in two modes as above. Output relay B operates as fault output (in case of input fault, relay B actuates and the
fault LED turns on while relay A repeats the input line as configured). Actuation can be configured in two modes:
No input fault / Energized relay (it de-energizes in case of fault) or No input fault / De-energized relay (it energizes in case of fault).
Note: use of voltage free electrical contacts with fault detection enabled requires, near the switch at the end of the line, a 1 K series connected resistor and a 10 K 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.
