D5062
- SIL 2 Vibration Transducer Interface
G.M. International ISM0184-7
Before powering the unit, check that all wires are properly connected, in particular supply conductors and their polarity and input and output wires; also check that Intrinsically Safe
conductors and cable trays are segregated (that is, they must have no direct contacts with other non I.S. conductors) and identified either by color coding, preferably blue, or marking.
Check conductors for exposed wires that could touch each other causing dangerous unwanted shorts. When the power supply voltage is turned on, the “power on” green led must be lit.
For 3 wires powered sensors, the sensor negative supply voltage (referred to common terminals “7” / “9”) must be more negative than -17 Vdc (supposing a 15 mA maximum value for
the transducer current consumption).
In addition, for 2 or 3 wires powered sensors, the output signal should be corresponding to the input sensor signal, verifying that the output signal is kept within the 0 to - 20 V range
(supposing a 10 K
Ω
output load). Instead, for 2 wires unpowered sensors, the AC output signal should be corresponding to the AC input sensor signal, considering that the output signal
also comprises a -10 Vdc component (absent in the input signal) because of the offset introduced by the DIP switch configuration for 2 wires AC transducers shown in the “Configuration”
section.
D5062 series is isolated Intrinsically Safe Associated Apparatus installed into standard EN/IEC60715 TH 35 DIN

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.
D5062 series must be installed, operated and maintained only by qualified personnel, in accordance to the relevant national/international installation standards (e.g. EN/IEC60079

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 area is known to be nonhazardous.
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
The D5062 series provides a fully floating DC supply for energizing vibration transducers, accelerometers or 2-3 wires sensors located in Hazardous Area and repeats the sensor input
voltage in a totally isolated circuit located in Safe Area to drive vibration monitors or analyzers for rotating machinery control and supervision purposes.
The module provides 3 port isolation (input / output / supply) and a “POWER ON” green led is lit when the unit is supplied.
Operation
Installation
D5062 series are Vibration Transducer Interface 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.
D5062 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 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.
In the “Function Diagram” section and on the enclosure side, a block diagram identifies all connections.
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

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

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. When installed in a Class I, Zone 2 Hazardous Location, the unit shall be mounted in a supplemental AEx or Ex enclosure that provides a degree of protection not less
than IP54 in accordance with UL/CSA 60079-0. 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. 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 D5062 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.
D5062 series must be connected to SELV or PELV supplies.
All circuits connected to D5062 series must comply with the overvoltage category II (or better) according to EN/IEC60664
