ADM Screen Overview
Setup Screen 4
NOTE: This screen will only be displayed if the Voltex
Dynamic Mix Valve is connected to the EFR network.
NOTE: To choose any of the following menu selections,
use the navigation buttons (BH) then press the enter
key (BF) to activate that selection. Reference
Advanced Display Module (ADM) on page 10 for
screen ADM menu.
Edit Mode: Select to enter or exit the editing mode for
the screen. Icon is grey when in edit mode and blue

Air Nucleation: This will enable the air nucleation sole-
noid valve. This cycles while dispensing to dose air into
the mixed material.
Delay Time: Amount of time before the air nucleation
valve toggles between the on time and off time.
On Time: Amount of time the air nucleation valve stays
on before toggling off.
Off Time: Amount of time the air nucleation valve stays
off before toggling back on.
Motor Speed: The RPM's that the motor will run at. The
Motor RPM Setpoint can be locked out using a pass-
word.
Motor Ramp Up Time: This changes the amount of time
in milliseconds the motor takes to get to the RPM set-
point.
EFR Dispense Wait: This will cause the EFR to wait until
the Voltex Dynamic Mix Valve motor is up to speed
before dispensing.
NOTE: 100ms is the fastest acceleration and 9000ms is
the slowest acceleration. The goal is to try and prevent
breaking mixers with a slower acceleration. Example:
500ms = half a second to get to the RPM setpoint of
4400RPM.
