Quick Start
This section provides a subset of the full technical manual to facilitate installation and start-up of
the LCI-90. For a complete technical description please refer to Sections 3.0-6.0.
2.1
Mounting
The LCI-90 will fit in a 7.15” x 5.25” cutout, with a minimum of 4.75” depth clearance (see
Appendix A for dimensional drawing). The instrument is held in place with removable
panel clamps that index into the slotted holes on all sides of the display. Four clamps are
included with each display.
After sliding the display into the cutout, clip the four panel clamps on the sides of the dis-
play, with the flanged end of the clamp facing away from the panel. Once the panel clamps
are installed, tighten the jackscrews against the panel to compress the LCI-90 gasket to seal
against the panel. Lock the jackscrews with hex nuts to prevent them from vibrating loose
over time.
2.2
Basic Field Wiring
Basic field wiring connections for the LCI-90 are those required for power, the force
transducer, and the quadrature Payout sensors. The base unit LCI-90 (i.e. no options) is
shipped with hardware settings to accommodate the following field devices: one 4-20 mA
Tension signal and two PNP proximity switch inputs for Payout. The LCI-90 can be
connected to a broad range of field sensors; wiring connections for these are explained in
detail in Section 4.0.
During installation, an appropriate disconnect device must be installed to provide a means
of disconnecting the display from the external power source for servicing. This disconnect
device is not provided with this equipment.
Input power requirements are 18-36VDC (nominal 24VDC) at 15 Watts. This device is a
DC device. This device is approved for Overvoltage Installation Category III.
The connection diagrams for the factory standard power input, Tension and Payout sensors
are shown in the tables below. The LCI-90 terminal blocks are listed on the left, and the
field devices are listed on the right.
