Fike BC2 Installation And Maintenance Instructions

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.
