Warnings
Failure to read and understand the information provided in this manual may result in personal injury or death, damage to the product or product failure. Please read each section in its entirety and be sure you understand the information provided in the section and related sections before attempting any of the procedures or operations given.
Failure to follow these precautions could result in serious injury or death. Keep these instructions with warranty after installation. This product must be installed in accordance with National Electrical Code, ANSI/NFPA 70 so as to prevent moisture from entering or accumulating within the controller housing.
ELECTRICAL SHOCK HAZARD
A qualified service person must install and service this product according to
applicable codes and electrical schematics.
Disconnect power prior to servicing any equipment.
- Do not connect power to this equipment if it has been damaged or has any missing parts.
- Do not install in areas with: excessive or conductive dust, corrosive or flammable gas, moisture or rain, excessive heat, regular impact shocks, or excessive vibration.
EXPLOSION OR FIRE HAZARD
Do not use this product with flammable liquids. Do not install in hazardous locations as defined by National Electrical Code, ANSI/NFPA 70.
Warning: Users must read this manual and understand controller operation before changing any settings. Entering incorrect settings may result in damage to equipment.
If the controller was shipped pre-installed in a control panel, some default values may have been changed at the factory in order to properly test the control panel operation. The user must adjust the settings to the requirements of the installation.
The user should always keep a record of the settings before making changes, in case there is a need to revert to previous settings. The user should also record all settings changed for use in programming a new controller in case a replacement is ever needed.
Always thoroughly test controller operation in the installed configuration to verify user settings.
Introduction and Specifications
Congratulations and thank you for your purchase of a control panel utilizing the Installer Friendly Series® controller. This manual explains the features and operations of the controller which was designed to operate up to two pumps for tank pump down applications. The controller automatically controls the operation of the pump(s) based on the status of float switches or C-Level™ sensor.
GENERAL
- One or two pump level controller
- Operates using float switches or C-Level™ sensor
- HMI – Rotary selector for menu navigation and editing settings
- HMI – High-Brightness 2.4” color graphic LCD display, 240X320 pixel resolution
PUMP CONTROL AND PROTECTION
- Automatic pump alternation (duplex)
- Multiple alternation configurations
- Automatic alternation on pump fault
- Pump run indication
- 1-2 Pump power relays, 240 Vac, 20A max.
SYSTEM
- Alarm counts
- Pump cycle counts
- Pump run time
ELECTRICAL SPECIFICATIONS
-
Universal 85-265 Vac, 50/60Hz

- Expansion communication port (RJ45), RS485, Modbus protocol
ENVIRONMENT
- Operational temperature -20ºF to 122ºF (-30ºC to 50ºC)
- Storage temperature -40ºF to 140ºF (-40ºC to 60ºC)
- Relative Humidity (RH) 5% to 95% (non-condensing)

Programming
HMI MAIN SCREEN
The main screen shows an overview of the system status including any active alarms.
USER INTERFACE
MAIN MENU
HAND/OFF/AUTO OPERATION
The HAND, OFF, or AUTO operating mode can be changed for each pump independently.
- An AUTO or OFF setting will always return the user to the main screen upon selecting.
- A HAND setting will return to the main screen upon selecting if the tank level is above the lowest float or the level sensor’s lowest setpoint. Once the tank level drops to the lowest float or the level sensor’s lowest setpoint, the controller will automatically be changed to AUTO mode.
- If the tank level is lower than the lowest float or the level sensor’s lowest setpoint, then the user must press and hold the enter button to enable HAND mode. Upon releasing the enter button, in this case, the controller will automatically be changed to AUTO mode and will return to the main screen.
CLEARING COUNTS AND ETMS
All counts and elapsed time meters in the “Counts and ETMs” are able to be cleared.
To clear an individual count or ETM:
- Navigate to the “Counts and ETMs” screen and to the data to be cleared.
- Press and hold the enter button.
- Navigate to “Yes” when asked to reset the value.
- Navigate to “Confirm” to clear the count or ETM, or to “Cancel” to exit without clearing the count or ETM.

TROUBLESHOOTING INFORMATION SCREENS
This section displays the current configuration of the controller. *The example shows a controller configured as a Duplex, Timed Dose using a 40” C-Level™ sensor for level sensing.
The simulator is used to verify the functionality of the controller by simulating the tank level.
This section displays the frequency of the C-Level™ sensor as measured by the controller, as well as the calculated tank level. The normal operating range of the C-Level™ sensor is between 1000Hz and 3000Hz. If the C-Level™ sensor frequency is operating significantly outside of the normal range, a “Sensor Fail” alarm will occur.
This screen displays the status of each float switch connected to the controller. *The example shows a controller configured as C-Level™ sensor control.
This screen displays the status of each pump connected to the controller. *The example shows a controller configured as Duplex.
This screen displays the status of the controller alarm.
This section displays the status of the general inputs on the controller.
This section displays the fault status of each pump connected to the controller. *The example shows a controller configured as Duplex with a thermal/seal fail module.
This section displays the status of the voltage buses on the controller.
I/O TABLES
All Digital Input functions are activated upon a contact closure to the Digital Input Common terminal.
Note:
Terminals TB1-3, TB1-5, TB1-7, TB1-9 commons are internally connected.
