INSTALLATION AND MAINTENANCE INSTRUCTIONS
WARNING
Read these instructions carefully and completely before
attempting to unpack, install or service the indicator.
This indicator is not a rupture disc and must be installed
downstream of the rupture disc.
Do not vent rupture disc/indicator assembly to an area
where it would endanger personnel or equipment. A baffle
plate on the outlet end of vent piping does NOT
necessarily prevent potentially dangerous discharge.
Always handle the indicator with extreme caution. Nicks,
scratches or foreign material may result in leakage or
affect indicator operation.
No brush, jet stream or other cleaning mechanism should
make contact with the indicator located downstream of the
rupture disc.
Specific attention must be paid to the circuit. Special care
must be taken to avoid applying any force to the circuit or
TEF actuator.
The BC2, BC2 LP, BC2-H2 is only suitable for bolted
flange joint installation with a flat face or raised face
surface. Other flange faces such as RTJ are not suitable.
The BC2, BC2 LP, BC2-H2 is not suitable for full bolting
holder designs. If a BC2, BC2 LP, BC2-H2 is required for
a full bolting holder design, consult factory.
When the BC2, BC2 LP, BC2-H2 is used with a
conductive fluid, the control system should incorporate a
latching mechanism to continue to indicate the open
circuit.
For BC2-H2 in Hydrogen, Acetylene and IIC Service: –
POTENTIAL ELECTROSTATIC CHARGING HAZARD;
clean the cable connector only with wet cloth or antistatic
products. Operators who touch the BC2-H2 connector
must wear ESD-safe clothing (e.g., antistatic clothes)
and connect human body to the ground with a grounding
device before touching the connector.
Following 2014/34/EU Directive for European countries, the
installation of burst indicator and the barrier has to comply with
EN 60079-14 standard. The equipotentiality of the grounding
between the place of installation of the barrier and the indicator
needs to be checked at the installation and periodically.
BC2 / BC2 LP / BC2-H2 INSTALLATION
1. Assemble the bolt-type disc holder assembly per Fike
installation instructions.
2. Read the BC2, BC2 LP, BC2-H2 tag completely to verify
that the size and type are correct for your system.
3. Check the BC2, BC2 LP, BC2-H2 to make sure there are
no tears in the diaphragm or any breaks in the indicator
circuit.
NOTE: Designs with PTFE diaphragm will have a small
hole and may have an "X" pattern thru the hole. Designs
with PFA strip will have slit near circuit connection. Sizes
½" and ¾" may not have a diaphragm.
4. Install the BC2, BC2 LP, BC2-H2 with bolt-type holder in
companion flange as shown in Figure 1. Gaskets are
supplied attached to the BC2, BC2 LP, BC2-H2, no
additional gaskets are required. Do not install any spiral
wound gaskets in the BC2, BC2 LP, BC2-H2 flange joint.
5. Verify that the BC2, BC2 LP, BC2-H2 is downstream of the
rupture disc.

6. Connect the BC2, BC2 LP, BC2-H2 receptacle to lead wire
NOTE: For hazardous locations, barriers must be CSA, FM, or
UL certified and must be installed in accordance with barrier
manufacturer's instructions.
Barrier parameters are as follows:
NOTE: For Hydrogen service, use only BC2-H2.
BC2-H2 is only certified for ATEX & UKEX (Not IECEx, Not
CSA).
NOTE: The burst indicator is intrinsically safe for Class I,
Division 1, Groups C & D, and Class II, Groups E, F, & G, and
Class III when connected through a listed safety barrier
(CSA, FM, UL)
U
NOTE:
the safety barrier shall be galvanically isolated.
