(a.a, aa.a, or aaa.a)
(c or cc)
Reads the current pump setup, where:
a.a, aa.a, or aaa.a = Flow rate in mL/min
b = Run status (0 = stopped, 1 = running)
c or cc = Pressure compensation
d = Pump head type (see RH command)
e = Pressure Board (0 = present, 1 = not present)
f = External control mode (0 = frequency, 1 = voltage)
g = 1 if pump started and frequency controlled, else 0
h = 1 if pump started and voltage controlled, else 0
i = Upper pressure limit fault (0 = no, 1 = yes)
j = Lower pressure limit fault (0 = no, 1 = yes)
k = Priming (0 = no, 1 = yes)
l = Keypad lockout (0 = no, 1 = yes)
m = PUMP-RUN input (0 = inactive, 1 = active)
n = PUMP-STOP input (0 = inactive, 1 = active)
o = ENABLE IN input (0 = inactive, 1 = active)
p = Always 0
q = Motor stall fault (0 = no, 1 = yes)
RE OK/ Resets the pump configuration to its default power-up
state.
# (no response) Clears all characters from the command buffer.
7.2 Rear Panel 6-Pin and 10-Pin Terminal Board Connectors
A 6-pin terminal board connector and a 10-pin terminal board
connector are provided on the rear panel. Any device capable of
providing the proper run/stop logic level, flow rate control frequency,
or flow rate control voltage can be used as a remote controlling device
for pump operation via this connection. The terminal board connectors
can be removed for ease of connecting wires, if desired, by pulling
firmly rearward and should be reinserted firmly afterward.
7.2.1 Pressure Fault and Motor Stall Fault Output
The pump's
output is on the 6-pin terminal board connector. The
pinout is:
Pin Function
6 EVENT 1
5 No connection
4 EVENT 2
3 No connection
2 EVENT 3
1 No connection
This output is produced internally by a reed relay which has SPDT
contacts with a 0.25 amp maximum, 50 VDC maximum, and 0.2 ohm
rating. The 6-pin connector allows wires to be connected to the
