Introduction
ThePR60DigitalPressureGaugeprovidesanaccurate
display of pressure. Pressure can be displayed up to
6550 units (PSI or Bars) or as a percentage (0 to
100%). ThePR60 is pre-programmedfor use withall
popular American and European resistive pressure
senders made by VDO, Teleflex, Mercury, GM,
Stewart-Warner, Centroid, Faria and others. Custom
0-5Vand4-20mAversionsarealsoavailableby special
order. Low and High level alarms can be set over the
entirerangeoftheinstrument/sender. When activated,
thebuilt-in 85 dB alarmwillsound and the displaywill
flash. Fivelevels of backlightingcanbeselectedand all
set-up, alarm values, sender type and maximum tank
capacity are saved in a non-volatile memory. The
PR60outputsNMEA0183serialdataorthis output pin
can be programmed to activate an external alarm.

Notes
Selecting NMEA 0183 or External Alarm Output
To toggle Screw Terminal Pin (C) between NMEA
0183 and External Alarm Output, press and hold
down both the tand s keys for 10 seconds (until
you hear a long beep). The new output mode is
automatically saved to memory. When the external
alarm output is activated, a 5V signal (10 mA Max.)
is output on screw terminal (C).

Installation
Before starting the installation, please read this
entire section first. Be sure to install the bulkhead
gasket before you install the instrument. Finger
tighten the screws that mount the instrument bracket
- do not use tools.

driver to make the connections to the screw terminal
on the instrument case back as shown in figure 2.
lCarefully check all your wiring against those
shown in figure 2. If everything is wired correctly
youcan mount thePR60 intheinstrumenthole. Be sure
the bulkhead gasket is in place and use only finger
tension to tighten the bracket hold-down nuts Do not
overtighten the bracket or you may damage the case
- do not use tools to tighten the nuts.
DisplayingPressure
Press the :key to display pressure (PSI or Bars).
Press the skey to display pressure in percent (0 to
100%).

Mounting and Wiring
lDrill a 2-1/8" (55mm) mounting hole where you
desire to mount the instrument (Figure 1).

Operation
Key Functions
The keys are used to select
backlightlevels, displaypressure(PSI,Barsor percent),
setthe low/high level alarms,selectsender type and set
themaximum senderpressure. Afterchangesare made,
thenewinformationisautomaticallysavedtomemory.
Backlight Intensity
Press the key for 1/2 second to adjust the
backlight level for night-time viewing. Each time
you press the "+" key for 1/2 second, the backlight
level will change: 1, 2, 3, 4, OFF, 1, 2, ... etc.
Setting Low/High Level Alarms
Whileviewing pressure, press andhold the tor skey
for ten (10) seconds to view/set the Low or High
pressure alarms. You will hear a long beep and the
alarmvalue is displayed. Pressthe sand tkeys toset
the desired alarm limit (000.0 to 6553 PSI or Bars).
Pressthe"+"keyfor 1/2 second to save your entry to the
non-volatilememory.
Alarms ON/Off
Press the sor tkey for 1/2 second to "arm" or
"disarm" the level alarms. The display will flash
"On" or "OFF" briefly to show you the state of the
alarms. You should leave the alarms armed at all
times and only disarm it to silence the alarm buzzer.
Selecting Sender Type
Press and hold down both the tand "+" keys for 10
seconds (until you hear a long beep.) Use the sand
t keys to select the correct sender from the list
below. Once the correct sender has been chosen,
press the "+" key for 1/2 second to save your entry.
