Operating Mode
Description
Duplex Control
This mode configures the controller as part of a 2
controller, 2 pump system. Both pumps will run at the
same varying speed. The staging and destaging of
pumps can be configured to create a lead/lag system. The
lead pump can be alternated based on elapsed time.
Speed Control
This mode configures the controller to accept a speed
command through an analog input, pulse input or
extended PI loop [21–**]. A start signal on DI 18 [5–10] is
required.
Test Run Mode
Test Run Mode allows the controller to be configured to
run the pump at specified speed for a specified amount
of time. The action will be started by a digital input (DI
19).
Single pump
The Single Pump Operating Mode is the default operating mode for the controller. Use
this mode for constant pressure, flow or level applications that use 1 controller operating
a single pump.
• The Application Type allows selection of the type of control. Select either Constant
Pressure, Flow Control or Level Control.
• Next select the appropriate units for the application. These units will be displayed on
the LCP default status screen.
If Level Control is the Application Type, select whether the application is a Tank Fill or
Tank Empty application.
• In a ‘Fill’ application the pump will speed up when the level in the tank drops below
the setpoint level.
• In an ‘Empty’ application the pump will speed up when the level in the tank is above
setpoint level.
• The
PID Normal/Inverse Control [20-81]
parameter is set to
Inverse
for the ‘Empty’
application and to
Normal
for the ‘Fill’ application.
The ramp times are selected next. Select from either a Fast, Medium or Slow ramp.
