External Operation
ANALOG INPUT OPERATION
In analog mode the pump will accept a milliamp signal and produce a pump speed proportional to the signal level
received. The input resistance of the analog signal is 250. The pump's response can be fine-tuned by variable set
points to meet system requirements.
(1) Power ON
When power is applied to the pump, the green indicator above
ON lights up, the display momentarily shows the software version
("Vx.xE"), and the controller goes to whatever mode the pump
was in when power was disconnected. If being powered for the
first time, the stroke rate is then displayed, the "WAIT" is lit, and
pump is then in the Wait Mode.
(2) Selecting the mode of EXT operation:
Press the EXT and the keys simultaneously. The WAIT
backlight disappears, the SET backlight is lit, and the display
shows "dIG" (if "ANA" is displayed, skip to step 3).
Change the mode by pressing the key. Every time the key
is pressed, it toggles between the ANA and dIG modes. (Pump is
shipped from the factory preset in the dIG mode)
(3) Press the START/STOP key to confirm the Analog selection and
return to the WAIT mode.
(4) Setting the Analog Input Set points:
(NOTE: Pump is pre-set at factory with the Analog set points set
at 4.0mA = 0 SPM and 20.0mA = 360 SPM. If these are the
desired set points, skip steps 4-12 and move to step 13.)
Press the EXT and keys simultaneously. The display will
show the initial set point (default is A04.0) and the SET and 1
backlight will appear.
