Liberty Pumps IP-Series - Manual (Page 4)

Operations
The Intelligent Panel Series control panel uses the Level Sensor to continuously monitor and control the liquid
level in the tank. An optional high water alarm fl oat and redundant off fl oat can be used to provide additional
protection from high or low water conditions.
Hand Operation
- The level must be above the stop/redundant off set point to put the panel in HAND operation.
To override the stop/redundant off set point, press and hold the HAND button. The pump runs until the HAND
button is released. The panel then returns to the AUTO mode. If the level is above the stop/redundant off set point
and the panel is placed in the HAND mode, and left in HAND mode, the pump continues to run until the liquid
level reaches the stop/redundant off set point. The panel then returns to the AUTO mode.
Off Operation
- The panel is in the OFF mode.
Auto Operation
- In time dose (t-dose) mode, when the panel is in the AUTO mode, the timer controls pump
ON and OFF time as long as the redundant off and timer enable set points are activated. In demand (d-dose),
the stop and lead set points control the pump.
Level Indicators - Illuminate if the corresponding set point is triggered.
Green Control and Alarm Power Indicators - (mounted on interior circuit board) Illuminates when
control power and alarm power is present. If the control fuse needs replacing the panel sounds an alarm.
LED Display - Used to view and set panel settings and cycle count data. Will turn off after fi ve minutes of non-use.
Viewing Panel Settings and Cycle Data
To view panel settings and cycle data press the NEXT button. Each time the NEXT button is pressed the
display will advance to the next setting or cycle data. Information will be displayed in the following order:
in - Level of the liquid measured from the zero point on the sensor. This will be shown in inches or centimeters
depending on the units selected.
t-dOSE or d-dOSE – Identifi es if the panel is confi gured as a time dose or demand dose panel.
Et 1 – Elapsed time meter for pump 1 shown in hh:mm:ss.
CC 1 – Cycle count for pump 1.
AL 1Ctr – Cycle count for Duo Alarm 1 option for single phase models OR
Cycle count for Pump 1 Fail for three phase models and single phase models with overloads.
Et 2 – Elapsed time meter for pump 2 shown in hh:mm:ss (duplex only)
CC 2 – Cycle count for pump 2 (duplex only).
AL 2Ctr – Cycle count for Duo Alarm 2 option for single phase models OR
Cycle count for Pump 2 Fail for three phase models and single phase models with overloads.
AL-Ctr – Alarm counter which includes high water alarm, fl oat error alarm, and Duo Alarm 1 and 2.
FE-Ct – Float error counter which counts how many times the water level drops below the bottom of the sensor
and when the optional redundant off fl oat opens.
tO-Ct – Timer override which counts how many times the liquid level has reached the timer override set point
(time dose only).
On – On time currently set for the pump shown in hh:mm:ss (time dose only).
OFF – OFF time currently set for the pump shown in hh:mm:ss (time dose only).
t-OFF or t-On – Display counts down the OFF or On time remaining in the cycle (time dose only).
