7.5 Footswitch Operation and Connector Functions
Plug the optional foot switch into the Interface Connector found at the rear of the unit. If the unit is at idle,
pressing the footswitch once, will initiate a pump dispensing sequence, as defined by the entries made by
the user via the main front panel keypad. If the unit is running, pressing the footswitch once will stop the
pump.
In addition to connections for the above footswitch, the
interface Connector contains feedback pinouts for a Pump
Running / Pump Stopped indicator.
Pins 1 (footswitch +) and 2 (footswitch GND) are +5V TTL
compatible inputs with pull up resistors, and can be driven
by an isolated open collector device or dry contact relay, to
start and stop the unit.
Pins 3 and 5 are an isolated transistor output capable of
driving a TTL load with pull up resistor. When the pump is
running, the transistor is ON, and when the pump is
stopped, the transistor is OFF.
See Figure F for connector pin out details.
7.6 Flexible Tubing Holder
An included flexible tubing holder mounts to either side of
the unit, and can be flexed to the desired position, for
hands-free operation of unit.
8.0 Unit Setup
