Foot Switch Reversed: Operates like the ‘Start/Stop’ key, whereby each rising edge either starts or
stops/pauses the Pumping Program.
Level Control: Falling edge stops/pauses the Pumping Program, Rising edge starts the Pumping
Program. This configuration can be used with a contact closure timer or in an automation
setup, allowing logic level control over the operation of the pump.
Start Only: Falling edge starts the Pumping Program. This configuration only allows the starting of
the Pumping Program. This would be useful, for example, with a laboratory animal
trained to press a lever. The animal can start the Pumping Program, but repeated presses
would have no affect until the Pumping Program permits it.
Start Only Reversed: Same as ‘Start Only’, but operates on the Rising edge to start the Pumping
Program.
Stop Only: Falling edge Stops the Pumping Program. This configuration only allows the
stopping/pausing of the Pumping Program. This would be useful, for example, with an
end of travel limit switch. Also, this switch can be used as a power on homing switch.
Stop Only Reversed: Same as ‘Stop Only’, but operates on the Rising edge to stop the Pumping Program.
Run on Low Level Starts the pump whenever the level is low
Run on High Level Starts the pump whenever the level is high
Stop on Low Level Stop the pump whenever the level is low
Stop on High Level Stop the pump whenever the level is high
Event Trap Trigger Redirects a program function Event Trap to be triggered by the trigger
input pin. When a Stop condition is triggered, the Event Trap will be triggered
instead of stopping the pump.
Pump Motor Operating (Pin 7): This output provides an external signal indicating when the pump motor
is operating. This pin is configured with the
n
setup command, or the "ROM" remote command.
When set to 0, the output is only at logic high when the motor is operating (pumping). When set to 1, the
output is logic high when the motor is operating or when the Pumping program is executing a pause timer.
Otherwise, the output is a logic low.
Pumping Direction Controls (Input: Pin 3; Output: Pin 8): Allows bi-directional control of the
pumping direction. The input pin, when activated, emulates the pumping direction key, changing the
pumping direction. This function, therefore, is only applicable where the pumping direction key would be
applicable. The function of the input pin is configured with the
aa
setup command, or the "DIN"
remote command.
When the mode is set to reciprocating pumps ("rE" setup command), then if the current pumping direction
is withdraw, a falling edge sets the direction to infuse. If the current pumping direction is infuse, a rising
edge sets the direction to withdraw. Otherwise, this input pin has no affect.
When the mode is set to dual pumps ("dU" setup command), then if the current pumping direction is
withdraw, a rising edge sets the direction to infuse. If the current pumping direction is infuse, a falling
edge sets the direction to withdraw. Otherwise, this input pin has no affect.
Dual and reciprocating pumping systems are created using 2 pumps attached with the accessory cable CBL-
TTL-1.
The output pin provides an output signal to external devices indicating the direction of pumping. A logic
low indicates withdraw, and a logic high indicates infuse. For example, this pin can be used to control an
external valve, allowing the syringe to refill from a reservoir.
