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.
Before turning power on, field load cell must be connected to the module. Then, turn power on, the “power on” green led must be lit, output must be in accordance with the
corresponding input signal value. If possible change the load cell condition and check the corresponding Safe Area output.
Installation
D5264 series is a Load Cell/Strain Gauge Bridge Isolating Repeater housed in a plastic enclosure suitable for installation on EN/IEC60715 TH 35 DIN-Rail, with or without Power Bus, or
on customized Termination Boards. D5264 series can be mounted with any orientation over the entire ambient temperature range.
Electrical connections 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 installations check the area to be nonhazardous before servicing). Connect only one individual conductor per each clamping point, use conductors up to 2.5 mm²
(13 AWG) and a torque value of 0.5-0.6 Nm. Use only cables that are suitable for a temperature of at least 85°C.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 function and location of each connection terminal using the wiring diagram in the corresponding section, for example:
Connect a 24 Vdc power supply voltage between terminals “9” (positive pole) and “10” (negative pole).
Connect current source mode positive output at terminal “1” and negative output at “2” or current sink mode positive output at terminal “2” and negative output at terminal “1”
Connect serial line Modbus output at terminal “11” and at terminal “12”.
Connect strain gauge bridge voltage supply at terminal “13” positive and terminal “16” negative.
Connect strain gauge bridge voltage sensing supply at terminal “14” positive and terminal “15” negative.
If strain gauge bridge has no internal voltage sensing capability always connect terminal "14" to terminal "13" and terminal "15" to terminal "16";
for better performance connect the wire at the end of the line near the load cells.
Connect strain gauge bridge output signal at terminal “17” positive and terminal “18” negative.
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)), make sure that conductors are well isolated from each other
and do not produce any unintentional connection. Isolation in accordance with EN/IEC 60079-11 clause 6.3.13 is provided between non-intrinsically safe circuits and intrinsically safe
circuits.
The enclosure provides, according to EN60529, an IP20 minimum degree of protection (or similar to NEMA Standard 250 type 1). The equipment shall only be used in an area of at least
pollution degree 2, as defined in IEC 60664-1. When installed in EU Zone 2, the unit shall be installed in an enclosure that provides a minimum ingress protection of IP54 in accordance
with IEC 60079-0. The enclosure must have a door or cover accessible only by the use of a tool. The end user is responsible to ensure that the operating temperature of the module is
not exceeded in the end use application.
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 D5264 series 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 modification must be avoided.
D5264 series must be connected to SELV or PELV supplies.
All circuits connected to D5264 series must comply with the overvoltage category II (or better) according to EN/IEC60664-1.
D5264 series is an isolated Intrinsically Safe Associated Apparatus installed into standard EN/IEC60715 TH 35 DIN-Rail located in Safe Area or Zone 2, Group IIC, Temperature T4
Hazardous Area within the specified operating temperature limits Tamb –40 to +70 °C, and connected to equipment with a maximum limit for power supply Um of 250 Vrms or Vdc.
Not to be connected to control equipment that uses or generates more than 250 Vrms or Vdc with respect to earth ground.
D5264 series must be installed, operated and maintained only by qualified personnel, in accordance with the relevant national/international installation standards (e.g. IEC/EN60079-14
Electrical apparatus for explosive gas atmospheres - Part 14: Electrical installations in hazardous areas (other than mines)), following the established installation rules; particular care
must be given to segregation and clear identification of I.S. conductors from non I.S. ones.
De-energize power source (turn off power supply voltage) before plug or unplug the terminal blocks when installed in Hazardous Area or unless area is known to be nonhazardous.
Warning: substitution of components may impair Intrinsic Safety and suitability for Zone 2.
Explosion Hazard: to prevent ignition of flammable or combustible atmospheres, disconnect power before servicing or unless the area is known to be non-hazardous.
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 Load Cell/Strain Gauge Bridge Isolating Converter D5264 series acts as a galvanic isolated interface installed between a PLC/DCS in Safe Area/Non Hazardous Locations and a
load cell (or a group of load cells) in Hazardous Area/Hazardous Locations. Up to four 350 Ωload cells, or five 450 Ωload cells, or ten 1000 Ωload cells can be connected in parallel.
It provides a fully floating power supply voltage with remote sensing capabilities to load cell located in Hazardous Area/Hazardous Locations and converts the mV signal from load cell
into a 0/4-20 mA signal according to user desired range.
Remote sensing wires (terminals “14” +Sense and “15” –Sense) must be always connected to force lines (terminals “13” +Exc and “14” –Exc) for proper operation of the unit, in case of
4 wires cell connect the sensing lines near to the cell connections to minimize the power supply voltage compensation error.
The Output circuit provides both current source and sink capabilities. Modbus output is also provided to interface PLC/DCS using digital communication.
The Presence of supply power is displayed by a green signaling LED.
The module is also provided with a PhotoMOS alarm output and an alarm indication red led. The module is totally software configurable by means of the GM PPC5092 adapter and
SWC5090 configuration software.
