The Libra Series of presettable counters is an economical and reliable solution to one or two preset level requirements. The LIBC1 and LIBC1E are the single preset versions and the LIBC2 and LIBC2E are the dual preset versions. All four units have a solid-state output and a Form C relay output for each preset. These units feature input configuration programmability, a full complement of control inputs, programmable timed outputs, non-volatile memory, and many other features which will satisfy most any single or dual preset level requirement. The Libra counters have two main counting actions, Reset to Zero (RTZ) and Reset to Preset (RTP). With RTZ, the counter resets to zero and counts up (if UP/DN terminal is at high level) and activates the outputs when the preset value(s) are reached. When RTP is used, the unit starts at the preset value and counts down (if the UP/DN terminal is at low level) and activates the output when zero is reached. For the 2-preset version, the count starts at preset 2 and counts toward zero. Output 1 fires when preset 1 value is reached and output 2 fires when the count reaches zero. There are eight modes of operation for the single preset unit and sixteen modes of operation for the dual preset unit. The timed output is programmed through the front panel buttons and can be programmed from 0.01 sec. to 99.99 sec. (The unit's timed output is set at the factory to be 0.1 sec.) The Libra counters have an internal non-volatile memory device which eliminates the need for battery back-up. When input power is removed, this device will maintain all data necessary for system operation. A Program Disable terminal is available, which is used to prevent accidental changes or tampering by unauthorized personnel to the preset(s) or timed output value(s). 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 checks all display driver and micro-processor hardware. The self-test can be run at any time without losing counts or missing a preset value. Power, input, and output connections are made via removable terminal strips located at the rear of the unit. These strips can accept one #14 AWG stripped wire. DIP switches at the rear of the unit are used to program the input configuration and to set the desired operating modes. The Libra Series counters have a metal die-cast front bezel, which is sealed, and meets NEMA 4/IP65 specifications for wash-down and/or dust when properly installed. Mounting clips are provided for easy panel installation.
