DVC6000 SIS
September 2013
2-36
NOTE: DO NOT CONNECT THE LOOP + TERMINAL IN THE LCP100 TO THE LOOP + TERMINAL IN THE DVC6000 SIS.
THIS WILL CAUSE THE LCP100 TO UNNECESSARILY CONSUME 4 mA AT THE EXPENSE OF THE DVC6000 SIS.

Method two can be accomplished in two ways; with
the wiring going first to the LCP100, then to the
DVC6000 SIS, as shown in in figure 2-32, or with the
wiring going first to the DVC6000 SIS, then to the
LCP100, as shown in figure 2-33. 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.
