restart time regardless of the number of Dry Well faults
detected. To select a fixed restart time, select  from within
the dSE parameter group. Then use the UP and DOWN
arrows to select the desired restart time. The default restart
time is 10 minutes. The restart time can be adjusted from 10
minutes to 50 minutes in 10 minute increments or from 1
hour to 48 hours in 1 hour increments.
SENSOR ZERO - SE0
The Sensor Zero function is used to calibrate the 0 PSI
output value of the transducer to the controller. Performing
the Sensor Zero will correct any errors in the pressure
reading on the Parameter Display. This procedure is
recommended when changing transducers. To perform
the Sensor Zero function, select SE0 from the Parameter
Group list and press MODE. If the pump is running, the
controller will stop the pump and will display SE0. After
the display shows SE0 bring the system pressure to 0 PSI
by opening valves to release the system pressure. After the
system pressure reaches 0 PSI, press the MODE button to
perform the Sensor Zero function. The display will blink
the SE0 screen to indicate the process has completed
successfully. If the display does not blink, ensure the voltage
on the pressure transducer input (measure DC voltage from
the white wire to the black wire) is between 0.3Vdc and
0.7Vdc. Press both the UP and DOWN buttons to exit from
the SE0 screen.
FAULT HISTORY RESET - S
The Fault History Reset function can be used to reset
the last four faults that are stored by the controller. This
function can be used as a diagnostic tool to track the
occurrence of faults or to validate that troubleshooting
efforts have solved an existing issue. To reset the controller
fault history, select S from the parameter group list and
press MODE. When the fault history has been reset, the
display will blink d.
SENSOR RANGE SELECT - SES
The controller can be configured to operate with pressure
transducers having different maximum pressure ranges.
This can be done to achieve a higher system pressure.
For example, if the controller is supplied with a 100 PSI
pressure transducer the maximum allowable pressure
setpoint is 85 PSI. If a pressure setpoint higher than 85 PSI
is desired a 200 PSI pressure transducer can be used which
increases the maximum allowable pressure setpoint to 170
PSI.
To configure the transducer pressure range, select SES
from the parameter group list and press MODE to enter
the parameter group. Use the UP and DOWN arrows
within the parameter group to select the desired maximum
pressure range. Select either: 100P, 200P or 300P for 100
PSI, 200 PSI and 300 PSI respectively. To select and save
the maximum pressure range, press MODE. The controller
will blink the pressure range to indicate the parameter was
saved. The indicator light in the lower right corner of the
display will indicate the selected pressure range.
NOTE: The pressure setpoint will be adjusted when
changing the sensor range. For example, if the pressure
setpoint is set to 60 PSI and the Sensor Range is set to
100 PSI and then the Sensor Range is changed to 200 PSI,
the resulting pressure setpoint will be 120 PSI. Ensure
the pressure setpoint is verified after changing the Sensor
Range.
RELAY CONFIGURATION - 
The  function can configure the Relay Output on the
UIB to activate under various conditions. The Relay Output
can be configured to activate when the pump is running
(), on a fault () or on when there is no fault ().
The relay can be used to control an external device such
as an auxiliary pump, accessory device or status sending
device. The relay can directly control an external device
rated up to 10A at 120Vac, or 5A at 240V . If the power
requirements of the external device are greater than these
ratings, use the relay output to power the coil of an external
power contactor or higher rated relay.
When the Relay Output is INACTIVE or OFF, the relay
is in the NORMAL state. In the NORMAL state the coil
of the relay is OFF and the contacts inside the relay will
connect the COM (common) terminal to the NC (normally
closed) terminal. The diagram below illustrates these
connections.
NC
RELAY OUTPUT
Relay Off/Normal State
When the Relay Output is ACTIVE or ON, the coil of the
relay is ON and the contacts inside the relay will connect
the COM (common) terminal to the NO (normally open)
terminal. The diagram below illustrates these connections.
NC
RELAY OUTPUT
Relay Active/On
The default setting is  which means that when the pump
is running, the relay is active/on and when the pump is off
the relay is off/normal state. Select  to activate the relay
when a fault occurs. Select  to activate the relay when
the system is not faulted. This setting is useful to detect
when the system has lost power. Note that the  setting
will not detect loss of power as a fault.
