What is the Level Alarm Control?
The Conair Level Alarm Control (LAC-1) is a simple-to-use early warning detection system for your blending equipment that is capable of monitoring up to six
levels of material at one blender with an extra input for auxiliary needs, typically a
surge bin or other material supply. Selector switches can be positioned to monitor
high or low material levels depending on your preference or blender application.
Audible and visual alarms indicate an excess or shortage of material within a
blender. The alarm indicates exactly which material bin is alarming with an associated LED.
Optional remote warning alarms can be connected to your control to alert you to
alarm conditions from remote locations with audible and/or visual indicators.

The LAC-1 has one additional connection terminal that has one N.O. (normally
open) and one N.C. (normally closed) dry contact that can be used to interface
with other processing equipment or monitoring devices. Two dry contact voltages
are available (24VDC @ 8 amps or 115VAC @ 10 amps). (i.e. an output used with
an alarm connected to a PC monitoring system) See Installation Section entitled,
Connecting Capacitance Sensors to the Level Alarm Control, for instructions to
connect the Dry Contacts.
Dry Contact
Terminal (No. 8)
Additional warning outputs are available to allow for additional blender material
warning notification. Two outlets on the LAC-1 provide power for remote warning
indicators. The top outlet will supply a line voltage of 110V or 220V power
(depending on the LAC-1 model) until an alarm condition is activated. The bottom
output will supply 110V @ 2.5 amps or 220V @ 1.3 amps power when an alarm
condition has been activated.

Preventative Maintenance
Checklist
Routine maintenance will ensure optimum operation and performance of the
Level Alarm Control (LAC-1). We recommend the following maintenance schedule and tasks.
• Every six months
❒ Inspect all wiring connections
Power and cable connections between the LAC-1 and the capacitance
sensors may become loose or wires may become worn. Tighten any
loose connections and replace any wire or cable that has become worn or
damaged.
❒ Inspect capacitance sensor mounting locations
Check for loose or dirty capacitance sensors. Capacitance sensors that are
dusty or dirty will trigger faults material level warning signals.
❒ Inspect the installation
Check installed LAC-1 hardware to make sure that the installation is
secure.
❒ Inspect the fuse
Check LAC-1’s fuse, replace as necessary.
5-2 l Maintenance
Replacing the Fuse
Replacement fuses are available from Conair.
The Level Alarm Control requires a 5 amp fuse for the 110V model and a 2.5 amp
fuse for the 220V model.
