Reads the current pump setup, where:
x.xxx, xx.xx, or xxx.x = Flow rate in mL/min y, yy, yyy, or yyyy = Upper pressure limit z, zz, zzz, or zzzz = Lower pressure limit PSI = Units (PSI, ATM, MPA, BAR, or KGC)
w = Pump head size (0 = standard, 1 = macro) v = Run status (0 = stopped, 1 = running)
u = Pressure Board present = 0; otherwise 1 
Identifies the pump type and EPROM revision x.xx
Sets the upper pressure limit in PSI. The maximum value for xxxx is 5000 for the plastic head or 6000 for the steel head; the minimum value is the lower limit plus 100. The value must be expressed as four digits, i.e., for 900 PSI xxxx = 0900.
Sets the lower pressure limit in PSI. The maximum value for xxxx is the current upper pressure limit setting minus 100; the minimum value is 0. The value must be expressed as four digits, i.e., for 100 PSI xxxx = 0100. Puts the pump in fault mode. Turns on the FAULT LED and stops the pump immediately.
Reads the fault status, where:
x = Motor stall fault (0 = no, 1 = yes)
y = Upper pressure limit fault (0 = no, 1 = yes) z = Lower pressure limit fault (0 = no, 1 = yes)
Disables the keypad. (Default status at
Enables the keypad.
Sets the pressure compensation value, where xx = the operating pressure (in PSI divided by 100),
i.e., for 0 PSI xx = 00, for 5000 PSI xx = 50.
Reads the pressure compensation value in hundreds of PSI, i.e., for 0 PSI x = 0, for 5000 PSI xx = 50.
Sets the pump head type, where:
x = 1 for a stainless steel 10 mL/min pump head x = 2 for a plastic 10 mL/min pump head
x = 3 for a stainless steel 40 mL/min pump head x = 4 for a plastic 40 mL/min pump head
x = 5 for a stainless steel 5 mL/min pump head x = 6 for a plastic 5 mL/min pump head
The pump is stopped; and, the pressure compensation and pressure limits are initialized, when the head type is changed.
Reads the pump head type, where:
x = 1 for a stainless steel 10 mL/min pump head x = 2 for a plastic 10 mL/min pump head
x = 3 for a stainless steel 40 mL/min pump head x = 4 for a plastic 40 mL/min pump head
x = 5 for a stainless steel 5mL/min pump head x = 6 for a plastic 5 mL/min pump head
