OPERATION
4.0 Operation
4.1 Output Adjustment Controls
1. Power Button: This button allows convenient starting and stopping of
the pump.
2.
Mode Selection Button: For pumps with external control capability (AD8,
AD9) this button switches pump operation between internal and external
modes. When operating in internal mode the Pulse Indicator Light will ash
green while pumping. When operating in external mode the Pulse Indicator
Light will ash yellow while pumping.
3.
Down Button: This button reduces the stroke speed of the pump. It will
reduce the stroke speed by 1 each time it is pressed. If this button is held
down, it will rapidly reduce the stroke speed. When a speed of 1 stroke per
minute (SPM) is reached the speed can be further reduced by pressing this
button again to enter stroke per hour settings.
4.
Up Button: This button increases the stroke speed of the pump. It will
increase the stroke speed by 1 each time it is pressed. If this button is held
down, it will rapidly increase the stroke speed. When a speed of 59 strokes
per hour (SPH) is reached the speed can be further increased by pressing this
button again to enter stroke per minute settings.
5. LCD Display: This display will show the stroke speed of the pump. Pumps
with theoretical (AD2, AD8, AD9) or actual (AD9 when combined with a
ow meter) ow will display the ow here.
6. Stroke Adjustment Knob: This knob provides adjustment of the stroke length.
Turning this knob clockwise 3 increases the stroke length, which results in
a higher amount of chemical displaced per stroke. It is recommended that
the stroke range stay between 20% and 100%.
7. Pulse Indicator Light: This light will ash green when pumping in internal
mode and will ash yellow when pumping in external mode. The light is on
between strokes and off during the actual stroke.
8. Low-Level Indicator Light: For units with Single-Level Float Sensors this
light will turn red when the Low-Level Sensor registers empty. This will turn
the pump off. For units compatible with Dual-Level Sensors (AD8, AD9) the
light will turn yellow when a low level is registered, and red when an empty
level is registered. The pump will turn off when it registers an empty level.
9. Output, Alarm, & Remote Mode Connector (6-Pin): This connector is used
for the special functions associated with the AD9 controls. For the AD9
this connector is associated with the 4-20ma out, Alarm Out, and Internal/
External remote modes.
1. Alarm Out (Red/White) – Programmed as either an Alarm Output or
Internal/External mode indicator. As an Alarm Output, pins 1 and 2 will
give a closure (solid state) triggered by: empty tank indication, input pulse
error, exceed batch error, or ow switch activation. For remote mode
indication it is open for internal mode and closed for external.
2. Alarm Return (Red) – Return side for the above pin 1 Alarm Out.
3. Remote Internal/External Mode (AD9) (Green) – This pin is programmed
as Internal/External remote mode control for an AD9. If programmed as
the Internal/External control, a closure will put the AD9 into external
mode.
