KD Scientific Legato 200 Series Syringe Pump User’s Manual

Publication 5617-002-Rev F

NOTE: When using triggers, the first step

in your program should define the trigger

starting level (High or Low). You may then

use the trigger command to change the

level as desired for your Program.

I/O (OUT) Trigger

The I/O (OUT) Trigger command is used to send a signal

to an external device when the Step in the Program is

reached.

The following options are available when setting an I/O

(OUT) Trigger command:

Trigger 1: Specifies output via the Trigger 1

(Pin 4) port. When selected, you must also specify

whether the signal to be sent is High Signal or

Low Signal.

High Signal: Sets the output signal to logic high.

Low Signal: Sets the output signal to logic low.

Trigger 2: Specifies output via the Trigger 2

(Pin 5) port. When selected, you must also specify

whether the signal to be sent is High Signal or

Low Signal.

High Signal: Sets the output signal to logic high.

Low Signal: Sets the output signal to logic low.

Synchronize: Select this to send a signal via Pin 6

to a connected pump to trigger activity. When

selected, you must define whether the desired

action is to start an Infuse activity or a Refill

(Withdraw) activity.

Start Infuse: Defines the rising edge signal

to trigger an infusion action.

Start Withdraw: Defines the falling edge

signal to trigger a refill (withdraw) action.

Valve: The pump automatically sends signals (via

pin 8) to activate/de-activate when the pump

changes direction. Use this feature to break that

feature and gain control of valve operation.

Valve On: Activates the valve.

Valve Off: De-Activates the valve.

Valve Auto: Returns pump to automatic

valve control mode.
