D1054
- SIL 2 Repeater Power Supply and Trip Amplifiers
G.M. International ISM0067-18
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, for 2 wire transmitter connection the supply voltage on each
channel must be
≥
15 V, output signal should be corresponding to the input from the transmitter, alarm LED should reflect the input variable condition with respect to trip points setting.
If possible change the transmitter output and check the corresponding Safe Area output.
D1054 is an isolated Intrinsically Safe Associated Apparatus installed into standard EN50022 T35 DIN Rail located in Safe Area/ Non Hazardous Locations or Zone 2, Group IIC,
Temperature Classification T4, Class I, Division 2, Groups A, B, C, D, Temperature Code T4 and Class I, Zone 2, Group IIC, IIB, IIA Temperature Code T4 Hazardous Area/Hazardous
Locations (according to EN/IEC60079-15, FM Class No. 3611, CSA-C22.2 No. 213-M1987, CSA-E60079-15) within the specified operating temperature limits Tamb -20 to +60 °C, and
connected to equipment with a maximum limit for AC power supply Um of 250 Vrms.
Non-incendive field wiring is not recognized by the Canadian Electrical Code, installation is permitted in the US only.
For installation of the unit in a Class I, Division 2 or Class I, Zone 2 location, the wiring between the control equipment and the D1054 associated apparatus shall be accomplished
via conduit connections or another acceptable Division 2, Zone 2 wiring method according to the NEC and the CEC.
Not to be connected to control equipment that uses or generates more than 250 Vrms or Vdc with respect to earth ground.
D1054 must be installed, operated and maintained only by qualified personnel, in accordance to 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), 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) following the established installation rules, particular care shall 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/Hazardous Locations or
unless area is known to be onhazardous.
Warning: substitution of components may impair Intrinsic Safety and suitability for Division 2, Zone 2.
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
.
Explosion Hazard: to prevent ignition of flammable or combustible atmospheres, disconnect power before servicing or unless area is known to be nonhazardous.
Warning
Operation
D1054 provides fully floating DC supply for energizing 2 wire 4-20 mA transmitters, or separately powered 3, 4 wire, 0/4-20 mA transmitters located in Hazardous Area/Hazardous
Locations, and repeats and converts the current to a 0/4-20 mA or 0/1-5 V or 0/2-10 V floating output to drive a load in Safe Area/Non Hazardous Locations. The circuit in the 4-20 mA
input, 4-20 mA output allows bi-directional communication signal for smart/hart transmitters. In addition to the analog output the barrier has also a two channel trip amplifiers providing
two relay SPST contacts, alarm A and B, that can be configured as HIGH, LOW, LOW start-up, BURNOUT alarm operating mode and NE or ND relay operating mode. Presence of
supply power is displayed by a green signaling LED, status of alarm output A and B is displayed by two red LED and also burnout condition of input lines is displayed by a red LED
(if enabled detection).
