to monitor ballast tank start/stop by microswitch or water sensing and failsafe

• simple setup of two servo positions
• Isolated (non-plating) water level detection
• Selectable servo position on dive + failsafe/surface
• 2 second radio failsafe
• Four status lights to aid alignment
• small dimension 1.3 x 1 x 0.4 inch (33 x 25.4 x 10mm)
• operates glitch-free with a poor radio signal

FAILSAFE MODES

Each force the ballast servo to FAILSAFE/SURFACE until the tank is empty

1. 2.5 second of radio failure
2. Receiver battery supply falling below 3.3 Volts.

Each force the the pump to stop immediatly

1. Ballast water reaching the lower a.c. probe/detector (blue/purple).
2. Ballast water reaching the upper a.c. probe/detector (yellow/green).

STATUS INDICATORS

1. Surface	(flashing) = pump inhibited/ ballst tank empty ON = servo set to surface/failsafe position
2 Dive	(flashing) = pump inhibited/ ballst tank full ON = servo set to dive/ position
3. Radio Fail	After 2 seconds ,set to surface until ballast tank is empty

SETUP PROCEDURE

To change the servo position on failsafe/surface

1. separate the green/yellow & twist blue/purple together
2. hold the button & move the stick until the servo hits the surface switch then release the button
3. repeat until the servo hits the dive microswitch
