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 suitability for Zone 2/ Division 2. Avertissement: la substitution des composants peut nuire à l’aptitude à la Zone 2/Div. 2.
Explosion Hazard: to prevent ignition of flammable atmospheres, disconnect power before servicing or unless area is known to be nonhazardous. Danger d'Explosion: pour
éviter l’inflammation d’atmosphères inflammables, débrancher l’alimentation avant l’entretien ou à moins que région est connue pour être non dangereuse.
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
Each input channel of Temperature Signal Converter D6072 accepts a low level dc signal from millivolt, thermocouple or 2-3-4 wire RTD temperature or transmitting potentiometer sensor
and converts, with isolation, the signal to a 4-20 mA floating output current to drive a load.
Presence of supply power is displayed by a “POWER ON” green signaling LED; integrity of field sensor and connecting line can be monitored by a configurable burnout circuit which, if
enabled, can drive output signal to upscale or downscale limit. Burnout condition is signaled by red front panel LED for each channel.
D6072D module has double input and output channel, and can also be programmed to interface a single input and obtain dual output channel (duplicator) or configurable output channel
(outputs can repeat the corresponding inputs or be proportional to the sum or difference of the two input process variables or with low/high selector function).
Installation
D6072 series are Temperature Signal Converter housed in a plastic enclosure suitable for installation on EN/IEC60715 TH 35 DIN-Rail, with or without Power Bus or on customized
Termination Board.
D6072 series can be mounted with any orientation over the entire ambient temperature range.
Electrical connection 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 mm
2
(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.
Connect alarm transistors checking the load rating to be within the maximum rating (100 mA at 60 Vdc (
≤
1 V voltage drop)).
The enclosure provides, according to EN60529, an IP20 minimum degree of protection (or similar to NEMA Standard 250 type 1). The unit shall be installed in an area of not more than
pollution degree 2 according to EN/IEC60664-1. When installed in EU Zone 2, the unit shall be mounted in a certified Ex enclosure that provides a degree of protection not less than IP54
in accordance with EN/IEC60079-15. When installed in a Class I, Division 2 Hazardous Location, the unit shall be mounted in a supplemental enclosure that provides a degree of
protection not less than IP54. The enclosure 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 D6072 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.
D6072 series must be connected to SELV or SELV-E supplies.
All circuits connected to D6072 series must comply with the overvoltage category II (or better) according to EN/IEC60664-1.
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.
Check that the module has been correctly configured through SWC5090 software. For details please see SWC5090 manual ISM0154.
Turn on power, the “power on” green LED must be lit, output on each channel must be in accordance with the corresponding input signal value and input/output chosen transfer function.
If possible change the sensor condition and check the corresponding output.
