LCP100 Local Control Panel
November 2013

Special Conditions for Safe Use
1. For Ex ic installations, it is not permitted to connect separate supplies to the LOOP+/LOOP and AUX+/LOOP
terminals.
2. If the equipment is installed in a zone 2, the installer shall take suitable steps to indicate whether the equipment is
installed as Ex e mb [ib] or Ex ic.
Mounting
Refer to figure 8 for dimensional information. The 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 for explosion-proof applications are shown in figures 3, 5, and 6. Electrical connections for
intrinsically safe applications are shown in figures 4 and 7.
Note
For intrinsically safe applications, the LCP100 forms an intrinsically safe explosion protection system when used with intrinsically
safe associated apparatus (a barrier) or with any other intrinsically safe devices.
The following requirements must be met: Uo ≤ Ui , Io ≤ Ii, Po ≤ Pi , Co ≥ Ci + Cc, Lo ≥ Li + Lc.
There are two 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 3 or 4, 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 5, or with the wiring going first to the DVC6200 SIS, then to the LCP100, as shown in figure 6 or 7.
However, because the LCP100 does consume energy to drive the pushbuttons 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.
