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.
6.7 Pump Motor Operating TTL Output Configuration
Command: "ROM <n>"
Configures the functionality of the 'Pump Motor Operating' TTL output pin (TTL pin 7).
Setting <n> Mode
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.
Sets the output to logic low when the Pumping Program is stopped
6.8 Lockout Mode
Command: “LOC <n>”, <n> Setting: '0' = Disabled, '1' = Enabled.
Lockout mode is useful for implementing Sub-Programs in a production setup.
Auto-Run Mode: When used in conjuction with the Sub-Program Select programming function (FUN PRI) 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 upon receiving an Operation Trigger input, the Pumping Program will
immediately begin executing the Sub-Program selected with the Expansion Port.
6.9 Notification Beep Mode
Command: “BP <n>”, <n> Setting: '0' = Disabled, '1' = Enabled.
Sets a continuous beeping at the end of the Pumping Program or waiting for a trigger input.
7. Pumping Program
A Pumping Program is simply a pre-defined sequence of actions, or functions, which guarantees consistent and
precise operation of the pump, automatically, and with or without any user intervention. A Pumping Program
can be as simple as continuous pumping at a fixed infusion rate. Or a Pumping Programs could consist of a
pumping rate and direction of pumping for a specified volume, then switch to another pumping rate. Also a
Program can interact with external devices through the TTL I/O connector, make decisions, or stop pumping
for a period of time.
Programs are broken into individual operations called Phases. Each Phase consists of a function that can be a
control function or pumping function. A pumping function, such as ‘RATE’, consists of a pumping rate,
optional “Volume to be Dispensed”, and the pumping direction.
Complex dispensing systems can be designed, involving multiple liquids, each dispensed from a different
pump, plus other equipment and sensors. Pumping Programs can be designed for each pump which enables
multiple pumps to synchronize with each other, and the other equipment and sensors, using a cable connected
to the TTL I/O connectors of each pump.
When the Pumping Program is started, either from the keypad, TTL I/O connector, or from RS-232, the
Pumping Program will begin with Phase 1 of the Program. After the completion of each Phase, the pump will
immediately start the next consecutive Phase. This linear sequence of Phases can be altered by certain
functions that direct the Pumping Program to continue operation with a different Phase number. Some
functions can change the order of operation conditionally based on external events.
