The DC-25T-DN-ANDON-NEMA-System is a fully integrated two-display timing solution designed specifically for multi-floor production environments where coordination and communication are critical to maintaining workflow efficiency. In this custom configuration, the system supports a two-level mixing process—an upper floor that houses the fill hopper and a lower floor where the materials are combined and finalized. Because the entire operation runs on a defined process time, accurate countdown visibility and clear status indication between both levels is essential.

This system consists of two separate but interconnected displays: a master unit and a secondary unit. The master is installed on the upper floor alongside the process controls, while the secondary unit is mounted on the lower floor to provide synchronized visibility and communication. Together, they function as one cohesive timing and signaling system.

The master unit is housed in a rugged NEMA 4X enclosure, built to withstand water, dust, and harsh industrial conditions. It contains all primary controls for setting and managing the countdown process. Operators on the upper floor set the total process time—representing the duration from when material is poured into the hopper until it reaches the lower floor and completes its cycle.

Key control features on the master unit include:

• Start/Stop push button
• Reset function
• Last Value recall
• Set Hours
• Set Minutes
• Set Seconds
• Adjustable countdown range up to 99 hours, 59 minutes, and 59 seconds

For repeat production cycles, the “Last Value” feature allows operators to quickly recall the previously used countdown time. For example, if the process runs at one minute per batch, the operator simply presses reset to restore that stored value and begin again without reprogramming.

Once the timer is started on the upper floor, the lower floor immediately knows material is in transit because both displays run simultaneously. If the process needs to be paused, the timer can be stopped, and the ANDON indicator will reflect the paused condition. When the countdown completes and the lower floor finishes its portion of the process, the operator presses the large 60mm normally open reset switch. This signals both floors that the batch is complete and the system is ready for the next run.

Communication between floors is accomplished through integrated ANDON signaling with three color indicators:

• Red – System idle or ready state (as requested by customer configuration)
• Yellow – Paused condition
• Green – Active timing process in progress

This visual communication ensures that both teams instantly understand the system status without verbal confirmation, reducing delays and improving coordination.

From an installation standpoint, the master and secondary units are connected with 25 feet of cable between enclosures. Communication data between the displays is transmitted via a simple two-wire connection, making setup straightforward and reliable. Inside each NEMA 4X enclosure are clearly labeled terminal blocks to guide wiring and simplify installation. The remote reset switch on the lower floor is connected using an additional 25 feet of cable, routed into the secondary unit for seamless integration.

Additional construction and environmental features include:

• NEMA 4X water- and dust-tight enclosures
• Cable glands for secure cable entry
• 10-foot 120VAC three-prong power cords
• Oil-resistant cabling designed for harsh industrial environments
• Terminal block labeling for simplified installation

Both the master and secondary units require power, ensuring continuous synchronized operation across both levels of production.

The DC-25T-DN-ANDON-NEMA-System is ideal for facilities that rely on timed batch processes spanning multiple work areas. By combining countdown timing, ANDON visual communication, and durable industrial construction, this system provides a reliable way to coordinate teams, standardize production timing, and signal completion status instantly.

Whether starting a new pour, pausing a cycle, or preparing for the next batch using the last value recall feature, this system keeps both floors aligned and informed—helping maintain consistency, reduce miscommunication, and streamline the entire production process.
