DESCRIPTION
The LNXN presettable counter is an economical and reliable solution to dual
preset level requirements. This unit features current sinking input
configurations, a high/low count frequency DIP switch, programmable timed
outputs, prescale capability with disable switch, non-volatile memory, and many
other features which will satisfy most dual preset applications.
The LNXN Counter has two main counting actions, Reset to Zero
(RTZ)
and
Reset to Preset (
RTP
). There are sixteen modes of operation for the LNXN dual
preset unit.
All parameters are programmed through the front panel buttons. The LNXN
counter has 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 presets, prescale or timed output values. The front
panel reset button can also be enabled or disabled by a rear panel DIP switch.
This counter also has 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 a fixed terminal block at
the rear of the unit. DIP switches at the rear of the unit are used to set up the
input configuration and to set the desired mode of operation.
The LNXN has a sealed high impact plastic bezel and meets NEMA 4X/IP65
specifications for wash-down and/or dust, when properly installed.
