10.1 TTL I/O Operational Controls
While the user is changing settings or configuration from the keypad, external control by the ‘Pumping
Direction’ and ‘Operational Trigger’ inputs will be ignored. These controls will also be ignored if an alarm
condition exists.
Operational Trigger (Pin 2): The input signal on this pin controls the operation of the Pumping Program. Its
functionality is user configurable. Use the ‘TR:nn’ Setup Default Configuration to configure this input pin.
(See Section 7.4, TTL I/O Operational Trigger Default Configuration)
Each option defines when the Operational Trigger input is activated. When activated, the trigger emulates the
‘Start/Stop’ key:
Foot Switch: Operates like the ‘Start/Stop’ key, whereby each falling edge (contact to ground) either starts
or stops/pauses the Pumping Program.
Foot Switch Hold: Falling edge starts the Pumping Program and the rising edge stops the Pumping Program.
With a foot switch, the Pumping Program will run while the foot switch was held down.
Foot Switch Reversed: Operates like the ‘Start/Stop’ key, whereby each rising edge either starts or
stops/pauses the Pumping Program.
