PR60
Digital Pressure Gauge/Alarm
Introduction
The PR60 Digital Pressure Gauge provides an accurate
display of pressure. Pressure can be displayed up to
6550 units (PSI or Bars) or as a percentage (0 to
100%). The PR60 is pre-programmed for use with all
popular American and European resistive pressure
senders made by VDO, Teleflex, Mercury, GM,
Stewart-Warner, Centroid, Faria and others. Custom
0-5V and 4-20mA versions are also available by special
order. Low and High level alarms can be set over the
entire range of the instrument/sender. When activated,
the built-in 85 dB alarm will sound and the display will
flash. Five levels of backlighting can be selected and all
set-up, alarm values, sender type and maximum tank
capacity are saved in a non-volatile memory. The
PR60 outputs NMEA 0183 serial data or this output pin
can be programmed to activate an external alarm.

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 t and 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).

Setting Maximum Pressure Range
Press and hold down the : key for 10 seconds (until
you hear a long beep.) Use the t and s keys to set
the maximum pressure for your pressure sender, either
in PSI or Bars. Once the maximum pressure is showing
on the display, press the : key for 1/2 second to save
this value into memory.
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.

l Carefully check all your wiring against those
shown in figure 2. If everything is wired correctly
you can mount the PR60 in the instrument hole. 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.

Mounting and Wiring
l Drill a 2-1/8" (55mm) mounting hole where you
desire to mount the instrument (Figure 1).
l Bring the sender wires, ground, and power lines
out of the mounting hole and use a small flat screw-
Selecting Sender Type
Press and hold down both the t and "+" keys for 10
seconds (until you hear a long beep.) Use the s and
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.

Setting Low/High Level Alarms
While viewing pressure, press and hold the t or s key
for ten (10) seconds to view/set the Low or High
pressure alarms. You will hear a long beep and the
alarm value is displayed. Press the s and t keys to set
the desired alarm limit (000.0 to 6553 PSI or Bars).
Press the "+" key for 1/2 second to save your entry to the
non-volatile memory.
Alarms ON/Off
Press the s or t key 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
