TTL I/O Directional Control Input Configuration
aa
Configures how the TTL input ‘Pumping Direction’ (pin 3) will control the pumping direction.
(See sec. 11.1, 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: 6.8.1
8.6
Pump Motor Operating TTL Output Configuration
n
Configures the functionality of the 'Pump Motor Operating' TTL output pin (TTL pin 7).
Settings: 0: Sets the output to logic high only when the motor is operating (pumping).
Sets the output to logic low when the motor is not operating or when the Pumping Program is
executing a pause timer or is stopped
1: Sets the output to logic high when the motor is operating (pumping) or when the Pumping
Program is executing a pause timer. Also alters operation of Alternating Communications Mode.
Set the output to logic low when the Pumping Program is stopped
8.7
Keypad Lockout
n
Setting: '0' = Disabled, '1' = Enabled.
*** The "Lockout Disable Key" needs to be inserted into the TTL I/O connector to display this setting***
When enabled, the "Lockout Disable Key" needs to be inserted in the TTL I/O connector to change any of the
pump's settings. When the key is removed, the user can only start or stop the pump and review current
settings. Settings can still be changed from RS-232. When the user attempts to change a setting, the message
will be displayed.
Auto-Run Mode: When used in conjuction with the Sub-Program Select programming function as Phase 1, the
pump will enter Auto-Run Mode. In this mode, on power up, the Pumping Program will immediately begin to
execute and the user would be prompted to enter a Sub-Program number.
