Control Box
2 Button Model (UNTIL October 2015)
The TF Series control box has a two-button operation, and a three-digit display, capable of counting up to
999 drops.
The LH button switches the unit on, and a subsequent press of the LH button will start operation of the unit.
A further single press will pause operation. Holding the LH button for three seconds will reset the counter to
zero. The RH Button switches the unit off fully, with negligible power consumption.
NOTE: The unit MUST be stopped before switching off, as this allows the unit to ‘park’ in the correct
position. Switching the unit off without stopping may result in feed being spilt if the slider stops in the
open position!
The unit also contains a 15amp fuse. This can be seen mounted on the circuit board below the counter mod-
ule. If the fuse blows, the unit will light up to indicate the fault.
