PUREMTC PBC-1 Proportional Ballast tank Controller



Product update:September 15, 2007
Features:
-Proportionally controls ballast tank volume.
-Microcontroller based.
-2 modes: Proportional control mode 2. Direct stick mode (e.g. Stick left->blow, stick right->flood)
-Transmitter trim lever as proportional control switch.
No sliding switch required.
-Fail safe: automatically blow ballast tank if signal were lost.
-Smart noise filtering.
-Smart power management.
-Small size, light weight.
-30mm, 45mm, 60mm trim range available

Note: This unit only provides standard PPM signal for controlling servo driven ballast tank. It does not have any driver, relay, or switch.

Signal specification (Pulse width):
Ballast blow: 1.0ms
Ballast flood: 2.0ms
Fail safe ballast blow: 1.0ms

Dimension specification:
1.38"x0.79"x0.12"(35mmx20mmx3mm)

Program the PBC-1 controller:
Step 1:
Move transmitter trim lever and sliding potentiometer lever to "Trim start" position. Reserve some trim lever space for emptying ballast tank command. Trim lever in front of(before) reaching the "Trim start" position will fully empty ballast tank. Configure the dip switch of the PBC-1 as show in the picture below to save the positions into PBC-1. When LED blinks, both trim lever and potentiometer positions have been successfully saved.

Step 2:
Move transmitter trim lever and sliding potentiometer lever to "Trim End" position. Configure the dip switch of the PBC-1 as shown in the picture below to save the positions into PBC-1. When LED blinks, both trim lever and potentiometer positions have been successfully saved.

Step 3:
Configure the dip switch of the PBC-1 as shown in the picture below for proportional control mode. The unit is now reay. Microcontroller will compute ballast tank volume based on the "Trim start" and "Trim end" position infomation.
