The proof test must be performed to reveal dangerous faults which cannot be otherwise detected. This means that it is necessary to specify how dangerous undetected faults, which
have been noted during the FMEDA analysis, can be revealed during the proof test.
The
Proof Test 1
consists of the following steps:
Testing procedure at T-proof
Steps
Action
1
Bypass the Safety-related PLC or take any other appropriate action to avoid a false trip.
2
Send a HART command to the repeater to go to the High (> 20 mA) alarm current output and verify that the analog current reaches that value.
This test is for voltage compliance problems, such as a low loop power supply voltage or an increased wiring resistance,and for other possible failures.
3
Send a HART command to the repeater to go to the Low (< 4 mA) alarm current output and verify that the analog current reaches that value.
This tests is for possible quiescent current related failures.
4
Restore the loop to full operation.
5
Remove the bypass from the Safety-related PLC or restore normal operation.
This test will reveal approximately 99 % of possible Dangerous Undetected failures in the repeater.
Steps
Action
1
Bypass the Safety-related PLC or take any other appropriate action to avoid a false trip.
2
Perform steps 2 and 3 of the
Proof Test 1
.
3
Perform a two-point calibration (i.e. down and full scale) of the connected transmitter and verify that the current output value remains within the specified values.
This requires that the transmitter has already been tested without the repeater and does not contain any dangerous undetected failures.
4
Restore the loop to full operation.
5
Remove the bypass from the safety-related PLC or restore normal operation.
This test will reveal approximately 50% of possible Dangerous Undetected failures in the repeater.
The
Proof Test 2
consists of the following steps:
D1014 series are 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 D1014 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.
D1014 series 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 nonhazardous.
Warning: substitution of components may impair Intrinsic Safety and suitability for Division 2, 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.
