TTL I/O Operational Trigger Default Configuration

aa

Configures the default mode of the TTL I/O ‘Operational Trigger’ (pin 2) that will control the

Pumping Program’s operation. This default setting can be overridden within a Pumping Program. (See sec. 10.1,
TTL I/O Operational Controls

). The 2 letter configuration Setting parameter to the right of the colon (:) is defined

in column ‘Setting’ as follows:

TTL I/O Directional Control Input Configuration

aa

Configures how the TTL input ‘Pumping Direction’ (pin 3) will control the pumping direction. (See

sec. 10.1, TTL I/O Operational Controls). The 2 letter configuration parameter to the right of the colon (:) is
defined as follows:

Setting Name

Function

rE

Reciprocating Pumps

Falling edge: Infuse; Rising edge: Withdraw

dU

Dual Pump

Falling edge: Withdraw; Rising edge: Infuse

The setting names are relevant to a 2 pump system, whereby the ‘Directional Control Input’ TTL pin is attached to
the second pump’s ‘Pumping Direction Output’ TTL pin.

In addition, “Directional Control Input” will affect how the “Sticky Direction” function operates. See “ Sticky
Direction”, sec: 5.8.1
