Linking Program Strings in the EEPROM
EEPROM program strings can be linked by ending one program string with an [e]
command that refers to a second program string.
Example Program Strings: [slZIA3000OA0G5e2R]
[s2gIA3000OgHD300G10GR]
The first string loads an initialization and prime sequence into program 1 of the
EEPROM (address switch position 1). It then links to string 2 in the EEPROM.
The second string loads an aspirate and dispense sequence into program 2 of the
EEPROM. The second EEPROM program string fills the syringe, then performs 10
dispenses of 300 steps each. The dispenses are triggered by an [R] command. This
string is repeated endlessly until the pump is powered down.
On power-up the pump will automatically initialize, prime and perform the multiple
dispenses until it is again powered down.

ORCES
Initialization moves the plunger to the top of the syringe, which is set to position 0. Also,
the output position of the valve is assigned to the left or right side, depending upon the
Initialization command, and all command parameters are reset to default values.
The top of the syringe is recognized in two ways:
•
upward movement of the plunger causes an overload condition
•
the home flag has been detected
If either of these conditions is not met, initialization will fail. The force at which the
plunger presses against the top of the syringe can be controlled via a parameter after the
Initialization command (possible values are 0 and 1).
Table 3-6 lists the recommended initialization force for each type of syringe.
CAUTION! To retain the integrity of the seal on smaller syringes, use a lower
initialization force than that for larger syringes. The default initialization
speed is 500 Hz.
