DESCRIPTION
The Lynx Series of presettable counters is an economical and reliable
solution to single or dual preset level requirements. The Model LNXC1 is the
single preset version and the Model LNXC2 is the dual preset version. Both
units have a solid-state output and a Form C relay output for each preset. These
units feature selectable input configurations, a full compliment of control
inputs, programmable timed outputs, prescale capability with disable switch
(dual preset only), non-volatile memory, and many other features which will
satisfy most any single or dual preset application.
The Lynx Counters have two main counting actions, Reset to Zero (RTZ) and
Reset to Preset (RTP). There are eight modes of operation for the single preset
unit and sixteen for the dual preset unit.
All parameters are programmed through the front panel buttons. The Lynx
counters have an internal non-volatile memory device which eliminates the
need for battery back-up. When power is removed, this device will maintain all
data set-ups necessary for system operation. A Program Disable terminal is
provided, which can be used to prevent accidental changes or tampering by
unauthorized personnel to the preset(s), prescale or timed output values. The
front panel reset button can also be enabled or disabled by a rear panel DIP
switch. These counters also have an on-line self-test, which can be run at any
time without missing counts or missing a preset value.
Power, input, and output connections are made via removable terminal blocks
at the rear of the unit. The Lynx Series of counters have a sealed high impact
plastic bezel and meet NEMA 4X/IP65 specifications for wash-down and/or
dust, when properly installed.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use this unit to directly command motors, valves, or other actuators
not equipped with safeguards. To do so, can be potentially harmful to persons
or equipment in the event of a fault to the unit.
