Displays the values of all analog inputs in volts. In the left column,
with all connected pumps at zero pressure, the pressure readings
should be near zero. Readings for pumps not connected are mean-
ingless.
After the initial reading, pressurize the pump and then observe the
test screen once more to verify that the value for that pump has
increased.
The right column represents the four analog input terminals on the
rear panel of the controller. For any terminal shorted to ground, the
value should read a steady zero.

From the Limits menu, you can set minimum and maximum flow rate
limits and pressure limits, as well as the maximum flow rate in Con-
stant Pressure Mode. High and low limits cannot exceed pump specifi-
cations.
The pump stays within these limits by means of a flag that moves up
and down with the ball nut assembly, and two optical sensors at the
top and bottom of the tower side plate as shown in Figure 9-3.
When a sensor is interrupted, it has a logic 1; when it is uninter-
rupted, it has a logic 0. Therefore:
• Upper limit 0, Lower limit 1
• Upper limit 1, Lower limit 0
• Upper limit 0, Lower limit 0 = Cylinder is partially full
• Upper limit 1, Lower limit 1= Illegal state
An illegal state can indicate failure of one or both sensors. The con-
troller display will toggle immediately between
