LCP100 Local Control Panel
Installation
The Fisher LCP100 Local Control Panel has four (4) mounting holes for on‐site mounting of the device. The LCP100
must be installed so that the wiring connections are on the bottom to prevent accumulation of moisture inside the
box.
Electrical Connections
WARNING
Select wiring and/or cable glands that are rated for the environment of use (such as hazardous location, ingress protection,
and temperature). Failure to use properly rated wiring and/or cable glands can result in personal injury or property damage
from fire or explosion.
Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval.
Failure to follow the local, regional, and national codes could result in personal injury or property damage from fire or
explosion.
Electrical connections are shown in figures 2‐3, 2‐4, and 2‐5. There are two different methods to power the LCP100.
Method one requires an external 24 VDC source to power the LCP100. Method two uses loop power wiring in series.
In method one, shown in figure 2‐3, signal wiring is brought to the enclosure through a 3/4 NPT or M20 housing
conduit connection (connection type is identified on nameplate.
Method two can be accomplished in two ways; with the wiring going first to the LCP100, then to the DVC6200 SIS, as
shown in in figure 2‐4, or with the wiring going first to the DVC6200 SIS, then to the LCP100, as shown in figure 2‐5.
However, because the LCP100 does consume energy to drive the push buttons and lights, the minimum current signal
from the logic solver must be 8 mA. If the logic solver cannot provide an output range of 8‐20 mA, then method one
must be used.
When connections are complete move the DIP switch to the appropriate power setting. If external 24 VDC is used to
power the LCP100, make sure the switch is on the side that says “24VDC”. If loop power is used, slide the switch to the
side that says “LOOP”.
Note
Factory default for the DIP switch power selector is 24VDC.
When installing the cover tighten the screws evenly in a criss‐cross pattern to help ensure the cover is properly
installed.
