DEKKER CONTROLLER OVERVIEW
Dekker’s Controller is standard on the Vmax models. The Dekker Controller provides for system control
as well as monitoring of system status. Service functions include display of spare parts list, maintenance
schedules, and service history, along with logging of fault conditions.
The Dekker Controller includes a 4-line large-font liquid crystal display, a durable Lexan membrane
keypad, and multiple status LEDs. Communication between controllers is via RS-485 for multi-machine
systems. An Ethernet port provides for remote monitoring and control via TCP/IP protocols and can be
enhanced with the use of Dekker’s OnDek Software (optional and purchased separately). Input and
output (I/O) includes 9 digital (24VDC) inputs and 7 dry relay contact outputs. Analog I/O includes 2 RTD
(Resistance Temperature Detectors) inputs, four 0-10VDC/4-20mA inputs, one 0-10VDC output, and one
4-20mA output. Power input to the controller is 24VDC.

The OnDek Dekker Controller
Battery
The Dekker Controller is shipped from supplier with a battery protector placed between the battery clip
and the surface of the battery, it may be a rubber sleeve around the clip or a small plastic insulator
between the clip and battery. This must be removed before applying power to the controller. If not
removed the controller will not retain Date, Time and other values that are written to the controller for
setup. The controller cannot be flashed with new firmware until this is removed. To remove use a pair of
needle nose pliers and pull from clip.

NOTE: When set up for multimachine, controller must be in STOPPED mode when changing Setpoints.
Multimachine Setup
Multimachine allows two or more Controllers to communicate and rotate Lead and Lag pumps based on
hours Run. When rotation occurs the pump with the least hours will rotate to Lead if the hours are
imbalanced. This keeps from putting all the run hours on one pump. To set up for multimachine CAT5
Ethernet cables are run from the RS485 jack mounted inside the panel. The cable is plugged into the jack
in the first panel, then routed to the second panel and plugged in. Each panel has two jacks so that you
can run cables to each machine if more than two. Cables must be run before setting the Controller up
for multimachine. Once cables are run go to first Controller and Enter Password.
Now press PROG button twice to view System Options Screen
Press DOWN arrow until Multimachine is selected.
Press ENTER.
Even though multimachine may already be set for 1 use UP button to move to 2 then back to 1

And press ENTER. Controller will reboot.
Go to second Controller Enter Password and follow same steps above only change multimachine to 2
and press ENTER.
If there are three controllers on the third set multimachine for 3. Do this for all Controllers each with a
different multimachine number starting with the first they should be, 1,2,3,4 etc.. When Controllers
power back up on each Controller it should show Units Found which will be the number of Units found
on the RS485 Bus. This should match the number of Controllers, if a Duplex 2, if a Triplex 3 etc..
Temperature Warnings And Faults
Temperature warnings and faults are factory set, It is not recommended to change these settings
without consulting with a Dekker Service Tech.

Rotation
When set up for multimachine the system will rotate pumps every 24 hours if needed. For rotation to
occur, the Lead pump must have the most run hours. When this condition is met and the time for
rotation occurs, the Lag pump will become the lead pump. If this condition is not met rotation will not
occur. If a triplex or higher system rotation for each pump will occur in order based on run hours of each
pump.
Manual Rotation
The pumps can be rotated manually, but the same condition above applies, the Lead must have the
most hours.
To rotate pumps manually, On the Lead pump, press and hold RESET button until you see the text
“Manual Transfer” appear on the screen, then release the button. Wait a few seconds and you will see
the upper text “LD” move to the opposite controller, the text “LG1” will move to where the “LD” was
previously.

Scavenger Output
Output 6 on the controller is used for a bleed valve. This output cycles on for 30 Secs and off for 9
minutes based on vacuum level. The vacuum level for cycling to occur is adjustable via the Setpoint

Faults and Fault Log
If a fault occurs the fault will be displayed on the screen and recorded in the fault log. Faults include
Overload, Temperature and in some versions of firmware Back Pressure. The Temperature and Back
Pressure faults are adjustable from the setpoint screen, but it is not recommended to change these
without consulting with a Dekker Technician. Changing these values could result in pump damage.
Below is what is shown on the screen when a temperature fault occurs. The Run Status light will also
turn red and flash so you can see a fault has occurred from a distance. Faults are cleared using the Reset
button, but will not clear until the condition that caused the fault is cleared.
