DigiMax Pump Controller
WELLMARK GENERAL PURPOSE DIGIMAX, 12VDC & 115VAC PUMPS
OPERATION/PROGRAMMING INSTRUCTIONS
FEATURES
The DigiMax controller is designed to control chemical injection rates through
intermittent motor control. The 12VDC version is designed to be operated in off-
the-grid battery powered systems for upstream wellsite chemical injection. A
115VAC version is also available for applications where power is available.
Control Features Include
• Auto Injection Mode – Enter injection rates directly using a
quarts/day input value. The controller will use the physical
characteristics of the pump and motor to determine cycle timing.
• Manual Injection Mode – Directly enter ON and OFF timing to
manually controller injection rates and cycle timing.
• Temperature Injection – Includes standard temperature sensor for
temperature-switched injection. Save chemical by disabling flow as
temperatures rise above a user defined setpoint.
• Serial Communication – Modbus RTU communication via 2-wire
RS485 connection.
• Onboard HMI – 8x2 LCD screen with 4 capacitive touch sense buttons
for local programming.
• Voltage Monitoring (12VDC Versions) – Measures voltage
continuously, which may be used to help predict solar application
power failures when connected to a user’s SCADA system.
• Cycle Totalizer – Totalizes number of cycles ran to help analyze
injection rates. Can be manually reset.
• Low Power – Screen backlight timeout conserves power when not in
use.
All programming selections made are retained upon power failure. Shutting the
main power switch off, or losing power will not affect controller settings upon
restart.

Basic Operation
Viewing Current Settings
The DigiMax controller uses capacitive-sensing buttons. There is no general
contact with the buttons and only requires a light touch. When a button is
pressed the LED above it will illuminate, notifying the user that the input was
registered.
While in normal running mode, the DigiMax will cycle through a series of “Idle
Screens” to display current settings. Idle screens will vary based on the injection
mode setting—pressing any of the keys will cycle through the idle screens.
