QUICK SET-UP GUIDE
1)
Determine what function the panel meter is to perform, e.g., rate display with alarm, batch
control, totalizer, etc.
control, totalizer, etc.
2)
Ensure compatibility with sensor. The DPF70 panel meters require a pulse (or contact
closure) input. The pulse must exceed 3 VDC and drop below 1 VDC. If necessary, as in the
case of paddle wheel, turbine meter or other types of inductive pick-up sensors, a signal
conditioner or pulse amplifier (such as FLSC-AMP) can be used.

3)
The wiring is explained on pages 3 and 4. The 12 VDC output can be used to power the
FLSC-AMP. For the DPF75, a single input at pin 5 can be jumpered to pin 6: input B will be
the grand total.

The relay function can be altered by cutting and/or soldering jumper traces as shown on
page 5.

There are two main operating modes: RUN, PROGRAM. (See page 6 for a summary). In the
RUN mode, the view key allows you to toggle the display for rate, batch and grand total. The
PRE A, PRE B keys allow you to see and set the relay trigger points. The lock key allows you
to lock and unlock the keypad functions by entering the lock-out code.

The PROGRAM mode must be accessed to set up the function of the display. In this mode,
the RST key enters the displayed value into memory. The PRGM key toggles the selections
and the arrow keys bump that digit up to the next value or change the decimal point location.

PROGRAMMING EXAMPLE
For this example, let's assume you have an FP-5300 paddle wheel sensor, an FP-5310 1" fitting, the
FLSC-AMP pulse amplifier and DPF75. You want to see flow rate (GPM) batch and grand total. The
signal K-factor is 183.66 pulses/gallon, (from the manual for the FP-5300 flow sensor). Here are the
programming steps you will see, starting on page 1.

FACTOR STEP 1: DPF75, DPF76, & DPF78
A,)
Set the decimal point for "dPFA" to allow two decimal places using the UP arrow key.
B.)
Enter the K-factor next: 183.66, using the arrow keys.
C.)
Do the same for "dPFB" (DPF75 only).
D,)
Choose "HI CPS", as the input will exceed 40 Hz (DPF78 only).
