Chapter 1 Introduction Thank you for purchasing the PLD-SCC1 Battery Odometer. The SCC1 is a compact and accurate mAh odometer/fuel-gauge which is simple to install and use. The SCC1 allows you to determine your remain- ing battery capacity using mAh counting rather than the less reliable voltage sensing methods that are used for Ni* and Li* chemistries.

(supply) and the ﬂight equip- ment (load) - (See ﬁgure 1.1) . Because each setup is different, the PLD-SCC1 is supplied with high current silicon leads which you will be required to ﬁt your own connectors or connect directly to your equipment.
Page 4: Setup Procedure
CHAPTER 1. INTRODUCTION Figure 1.1: Installation 1.4 Setup Procedure A note about choosing what battery capacity to conﬁgure the SCC1 with: It is recommended that you put in a capacity that is 10~15% lower than the actual stated capacity of the battery pack, so for a 1000mAh battery, set the SCC1 to 850~900mAh.
Page 5 CHAPTER 1. INTRODUCTION 1 Boot the device. This can be achieved either by power cycling the unit or pressing the user-button until the buzzer sounds 2 When the boot screen appears there is a 2-second waiting window during which you need to press and hold the user-button until the Battery Capacity screen appears.
Page 6 CHAPTER 1. INTRODUCTION 3 Press and hold the user-button until the required battery capacity is obtained, or press the button individually to obtain 50mAh capacity increases. Figure 1.4: Battery capacity setup (end) 4 When the required battery capacity is entered you can wait 5 seconds and the SCC1 will exit the setup mode and proceed to the normal data-display mode.

Chapter 2 Data Displays When the SCC1 initially boots or has been reset, the ﬁrst display will show the full battery mAh capacity and a zero running time. The data display will cycle to the next screen approximately every 1.5 seconds.

DATA DISPLAYS Figure 2.2: Time and remaining capacity screen after 5m32s This screen shows that the system has been running a total of 5 minutes, 32 seconds and there 673mAh of capacity left before the alarm will trigger. Figure 2.3: Current battery voltage Shows the current voltage of the battery.
Page 9 CHAPTER 2. DATA DISPLAYS Figure 2.5: Peak average current Shows the highest average current detected during the current power-on period since the last forced reset. The peak current de- tection becomes more sensitive as the current levels increase, this is due to the peak being calculated from the time interval between consecutive pulses from the mAh counter chip.

Chapter 3 Battery Empty, Battery recharge Reset and Power-out 3.1 Battery Empty When the SCC1 has computed that the available mAh remaining is zero (0mAh), it will commence to emit several small beeps periodi- cally and ﬂash the green LED. You will be required to Reset the SCC1 to “reﬁll”...

CHAPTER 3. BATTERY EMPTY, BATTERY RECHARGE RESET AND POWER-OUT 3.3 Restarting the SCC1 after being powered off When the SCC1 is powered down and powered back up, the Time elapsed and consumed mAh capacity will be retained, however the Peak current, minimum voltage and battery voltage will be reset. This will be the typical behaviour during a normal ﬂying day.
