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.
