Chapter 2 Installation
2.1 Battery Installation:
All DPF500 models are shipped without the battery(ies) installed. This preserves battery life when the unit is not in
service. When using external DPF5-BP, mount within 12" and plug connector into 3 position square posts (see Fig
1). Polarity is not a concern because center is common.
To install the battery, begin by locating the battery holder. The DPF502 and DPF503 require opening the enclosure
cover and removing the DPF500 to expose the battery holder.
The plus terminal of the battery is marked with a (+) symbol stamped into the battery holder. Be sure to install the
battery(ies) correctly.
Install battery(ies) to begin setup procedure. See Programming Flowchart to setup desired operating parameters.
2.2 Battery Replacement:
The DPF500 has a battery monitor feature which illuminates when the lithium battery voltage approaches its end
of life. A descriptor, “BAT”, illuminates when the battery voltage falls below this predetermined value. The low bat-
tery detector operates correctly with all power options.
The battery, or batteries, should be replaced within several weeks of the fi rst occurrence of low battery warning,
“BAT”. Left unattended, the unit may become inaccurate, cease to operate or malfunction.
Before replacing the battery(ies), Press the ← (left arrow) key to save the totalizer. The display will show "SAVE
TOTAL". This will save the current total value and the total will resume from this value when the new battery(ies)
is(are) installed. NOTE: If the display starts to fl ash after the "
SAvE totAL" message times out, press the "E" (enter)
key. If the message "E FLASH" is displayed, then there was not enough power left to save the setup and totalizer
to fl ash memory. At this point you must record the totalizer and setup information and re-enter the setup data after
the new battery(ies) is(are) installed.
Install new battery(ies) as described above.
