NOVAK SMART TRAY DISCHARGING INSTRUCTIONS
1. To use the included AC transformer for power (#4500 U.S. Version only), plug the transformer into a 120VAC wall socket, and plug the other end into the barrel connector located on the Smart Tray's right end cap.
2. To power Smart Tray from a 12-15VDC power supply, connect included DC Power Supply Harness to your power supply--Connect the WHITE wire to the supply's positive (+) output & the other wire to negative (Ð).
3. Upon power-up, the Smart Tray's 2-digit display will indicate the selected cut-off voltage (shown in volts per cell). To select a different cut-off voltage, press & hold the push button on the right side of the faceplate until the desired voltage is displayed, then release the button. The Smart Tray remembers the cut-off voltage settting even after the power is disconnected.
4. Carefully 'snap' battery pack down into the clips on the Smart Tray--Line up battery pack so the ends where you make the positive & negative connections match up with the "+" and "Ð" symbols marked on the Smart Tray's circuit board (under the Lexan faceplate by the outside bottom clips). Some packs may need to be put in upside down to match up properly & packs with fewer than 6 cells need to be placed all the way to the left side of the Smart Tray with the negative end of the pack matching with the "Ð" mark.
5. Make sure the Smart Tray's clips make good contact with all of the battery pack's cells (the clips sometimes get bent & must be pushed back into position). If the pack wants to pop out of the clips, you may need to solder your battery bars lower on the ends of the cells.
6. To start discharging, press the push button with a quick press. Another quick press will stop the discharging. During discharge the cell status LEDs will come on, indicating which cells are discharging. Once the individual cells have reached the set cut-off voltage, their LEDs will go out. When all status LEDs are out, the battery pack is finished discharging.
¥ OPTIONAL DEAD-SHORT PROCEDURE ¥
IMPORTANT NOTE: Novak Electronics does not recommend the process of dead shorting batteries, as this causes significant damage to the cells. Novak will not be held liable for any damage resulting from the use of this feature.
A. With no battery pack in the discharger, disconnect the Smart Tray from the power source it is connected to (if connected).
B. Press & hold the Smart Tray's push button while reconnecting the Smart Tray to its power source. After the Smart Tray is powered-up, release the push button. The 2-digit display should now show "dS", indicating the the Smart Tray is is the 'Dead Short' mode.
C. Place your battery pack into the Smart Tray's clips as in step 4.
D. The Smart Tray's discharge process will drop the cell voltages to below 0.1V/cell. After the cell voltages drop below 0.1V/cell, the individual cell status LEDs will blink every few seconds--indicating a dead short condition. Leave the batteries on the Smart Tray for about 15-30 minutes after the LEDs start blinking, then remove the battery pack from the Smart Tray.
E. After the Smart Tray's input power is disconnected, the unit will exit the Dead Short mode, and must be forced back into it by repeating steps A & B.
