Management of Change
Management of Change (MOC) is a procedure used to proactively manage changes
that have the potential to impact safety or the process within a plant. Evaluating
new techniques for improving MOC approval procedures can have an impact on
plant efciency. Historically, upgrading obsolete products or replacing existing
process control equipment had been delayed or abandoned due to the extensive
paperwork involved in completing a complex MOC approval sheet.
Background
The Fisher™ LCP100 local control panel is used to open, close, or test safety
shutdown valves communicating with a FIELDVUE™ DVC6200 SIS digital valve
controller. The LCP200 local control panel includes signicant improvements over
the LCP100 model. It is housed in a stainless-steel, explosion-proof enclosure. It
is also intrinsically-safe and suitable for use in various hazardous environments,
including Zone 0 (certications in progress). The device has added relay output
(SPDT) capability, the Trip and Reset relay outputs are SIL 2-capable.

Question & Answer Checklist
Q: Does the proposed modication cause any changes to the piping and

instrumentation diagram (P&ID)?
A: Not required for the base LCP200 device functionality. If the added
relay output (SPDT) capability is used, then the P&ID needs to be
updated with the additional wiring.
Q: Does the proposed modication change process chemistry,
technology, or operating and control philosophies?
A: No.
Q: Does the proposed modication change how the existing plant is
operated?
A: No.
Q: Does the proposed modication change process ows?
A: No.
Q: Does the proposed modication change existing pressure relief cases?
A: No.

Q: Does the proposed modication change the process description?
6
A: No changes are required for the base LCP200 functionality. If the relay
output (SPDT) capability is used, then the operating procedure needs
to be updated.
Q: Have the codes and standards to which the new equipment was
7
8
designed changed?
A: The LCP200 is explosion-proof and instrinsically safe, so it complies
with the appropriate requirements of hazardous area standards. See
the product bulletin for details.
Q: Does the proposed modication introduce new equipment that
requires spare parts, manuals, maintenance procedures, or training to
teach maintenance best practices?
A: Yes. The instruction manual provides the details of spare parts and
maintenance procedures.

require periodic predictive maintenance?
A: No.
Comparison of LCP100 and LCP200 Local Control Panels
The following information is intended to provide a general comparison between
current Fisher LCP100 and LCP200 local control panels.
Dimensional Comparison
Take note of the dimensional and weight differences between the LCP100 and the
LCP200 devices. The LCP200 device is about ve times heavier than the LCP100
device, due to its explosion-proof stainless-steel enclosure. The dimensional
differences are shown in Figure 1.

Conduit Entries
The conduit entry threads are integral to the body in the LCP200 device, unlike the
external cable entries in the LCP100 panel. See Figure 3.

Buttons or Lights
The LCP200 device has blanks that can be installed in the place of unused buttons
and lights. Any light can be blanked by using the blank kit available as a spare part.
The lens caps are user-interchangeable.
Terminal Box & Relay
The LCP200 has a dedicated terminal box for making the terminal connections.
Unlike the LCP100, the LCP200 does not have redundant terminals. A junction box
may be required.
The LCP200 auto detects if 24V power is being applied and so there is no switch to
be turned on when using Loop or 24V power.
The LCP200 has a NO – NC relay for the Trip and Reset buttons as well as a test relay
for when the diagnostic is in progress. These relay contacts change state when the
respective button is pressed or diagnostic is in progress.

Conclusion
The LCP100 device has been proven in use for many operating years. The design
philosophy of the new LCP200 panel maintains the behavior of the LCP100 device
while adding functionality, thereby allowing for an easier product transition.
