2. Set Points
The same basic format is used for defining each available analog probe input's control parameters..
>SYSTEM 1 SET POINTS<
NOTE: In the Setpoints pop-up screen the direction (Rising or Falling) of the setpoint can also be set. If
the setpoint is configured for 'Rising' the pump output relay will activate when the PSI reading exceeds the
setpoint. The pump output relay will remain activated until the PSI reading falls below the setpoint by the
amount of the differential. If the setpoint is configured for 'Falling' the pump output relay will activate when
the PSI reading falls below the setpoint. The pump output relay will remain activated until the PSI reading
rises above the setpoint by the amount of the differential.
2.5 Aux Inputs
Auxiliary inputs are the digital inputs for optional Flow Switch and other digital inputs such as low drum level
alarms. From these menus the user can set if they want each of the alarms Displayed, Remote Notification,
both or none.

2.6 4-20mA Out
Units with a 4-20mA output option will have a menu for setting up the 4-20mA output. The 4mA and 20mA
values can be defined by giving the output proportioning capability. i.e. 4mA = 0.0 PSI and 20mA = 100.0
PSI.

Note: Digital inputs can have the direction selected
between OPEN or CLOSED as the alarm polarity. If
DIGITAL 1
set for CLOSED the input will be in alarm when it sees

SIGNAL SOURCE - Select which probe reading the
mA will use as its reading source.
4 mA VALUE - What the 4mA signal equals
20mA VALUE - What the 20mA signal equals on the
assigned signal sources scale.
SET POINT - What reading turns the relay on
DIFFERENTIAL - Amount reading changes by before
the relay is turned off (min. 5 PSI diff. recommended).
HIGH ALARM - What reading generates a High alarm
notification.
LOW ALARM - What reading generates a Low alarm
notification.
