Installation
Use the double adhesive strips on the back of the mod-
ule to mount the AD30 to the pump or any other clean,
flat surface. If screw mounting is desired, use the two
screw holes provided on the sides of the unit.
Connections
If the AD30 was ordered with a pump connector for your
pump, connect the pump by plugging it in. If there is no
pump connector, follow the connections diagram. Con-
nect to the analog signal as shown.
Operation
Pulse output from the AD30 increases or decreases pro-
portionally with the 4-20 mA input signal. At 20 mA,
output is at the rated maximum strokes per minute, and
at 4 mA there are no pulses.
Repair
There are no field-repairable components in the AD30.
If the unit should fail to operate, contact your distributor
or SeaMetrics for information.
