1-4. Outline
1. You can monitor up to eight trouble occurrence reports with a single receiver and eight
transmitters AN426TⅡ.
At the transmitter, there are two selectable input methods: one with four push buttons (1
(orange), 2 (red), 3 (green), 4 (white)) and one with four external inputs (1 (orange), 2 (red),
3 (green), 4 (white)). According to possible trouble occurrences in the production line, you
can assign each color a meaning, such as red for an exception occurrence, orange for parts
out of stock, green for requesting transportation of finished products, or white for trouble
solved.
The indicator with the same number as the kiki number set in the transmitter lights up (or
blinks).
2. The receiver performs the external outputs (open collector outputs and relay output) in
synchronization with the lighting (or blinking) of the indicator.
3. Since the communication channels can be set from 1CH to 10CH, interference can be
prevented even when multiple receivers are installed.
In addition, 10 set numbers and 10 unit numbers can be set for each channel, so it is
possible to identify up to 1,000 receivers.
* The transmitter and the receiver are shipped with the same communication channel, set
number, and unit number set.
4. The receiver is a double-sided display type.
5. You can select the display method of the indicator from lighting or blinking. It is possible to
set the display method for push button input and external input individually. For the display
method, refer to “2-2-2. Display Method Setting”.
6. In addition to the indicator lights, an optional speaker can be installed that enables sound
notifications. A different melody for each indicator color can be configured (when multiple
colors are illuminated, the melody is selected according to the priority order). For details on
the speaker, refer to “4. Speaker (Option)”.
