Control Box
The Control Module has two modes of operation; count and countdown mode (the latter is recommended for most users).
Count Mode: Unit counts up from 0 e.g. 1,2,3,4,5 indefinitely, until the count is paused or the unit
switched off. If the counter reaches 999 then it will reset to 000.
Countdown Mode: The desired drop count is set using the up / down arrows in increments of 5. The unit will then count down and stop at zero.
THIS IS THE RECOMMENDED MODE OF OPERATION!
The unit can be fixed to a suitable surface on the towing vehicle using screws through the fixing lugs hidden under the two flaps on the left and
right of the unit.
Specification
Supply Voltage:
12V DC nominal, 16V MAXIMUM
Power Consumption:
OFF: 0.01A
Operating Temperature:
Fuse:
Thermal Reset Polyfuse (Non-serviceable) Operating life: 100,000 cycles
Protection rating:
IP67
Polarity protection:
Diode
NOTE: This control box features several thermal-rest polyfuse. If this fuse is tripped through a fault condition, the fuse will
reset after approximately 30 seconds when the fuse has cooled sufficiently. In hot ambient conditions this can take
significantly longer; likewise, in cold ambient conditions this will take less time.
Operation - Count Mode
1.
Switch the unit on by pressing the ON / OFF button. All segments of the display will light up.
2.
After approx. 3 seconds the display will show 000.
3.
Press Run / Pause to start the motor. The unit will count up from 0. Pressing RUN / PAUSE when the unit is running will stop the motor
and pause the counter. Holding RUN / PAUSE for 3 seconds will reset the counter to 0.

Fault Codes & Counter Troubleshooting
OL = Overload. Motor or slide plate jammed, or plug / socket connection is poor. Check plug / socket connection and check slide
plate is not jammed.
F1 = Sensor Fault. No output is being received from sensor. Check plug / socket for dirt or corrosion preventing contact. Check
sensor for damage or corrosion. The unit will continue to operate with this fault but will not count. To exit this fault condition
once the problem has been identified turn the unit off. by holding the ON/OFF button unt the unit switches off.
The control box MUST receive a signal from the sensor in order to 'park' the motor in the correct position with the slide SHUT. If no signal is
received for approximately 5 seconds the F1 error will show up. If this is the case the unit can be switched off by holding down the ON/OFF
button for several seconds, however please not that the motor may stop with the slide plate open in this case, allowing feed to escape.
For most instances of F1 error the cause is generally connector or cabling. First and foremost check connectors ae clean, making good contact and
there is no damage to the cable. Dirt or corrosion can lead to poor contact and unreliable sensor signal, culminating in an F1 fault code.
