RPM4-AD™ OPERATION AND MAINTENANCE MANUAL

Edit the upper and lower limit values as desired. Use the cursor control keys to move
between the two edit fields. The lower limit must be a negative value. Press
[ENT] to return
to the MAIN RUN screen with the new upper and/or lower limit active. Press [ESC] to return
to the MAIN RUN screen with no change to the limits.
When the upper or lower limit has been exceeded, the display of current pressure flashes
and a buzzer sounds for 3 seconds on/2 seconds off intervals. Change the pressure applied
to RPM4-AD so that it is within the upper and/or lower limit to return to normal operation.
Upper limit values are specific to each range and measurement mode. Be careful not to
assume that the upper limit set in one measurement mode will apply to the other. For
example, if you change the upper limit in gauge mode, the upper limit will not be changed in
negative gauge mode.
3.4.4.1 OVER PRESSURE FUNCTION
In addition to the UL function, RPM4-AD has an over pressure function.
The over pressure function executes when a Q-RPT measures a pressure that is
104 % of its maximum working pressure.
The over pressure function causes the measured pressure display to flash.
SDS closes shutting off the
TEST port (see Section 3.2.8). The overpressure
function also logs the time and date of the overpressure condition in both user and
factory logs to assist in incident diagnosis (see Section
Error! Reference source not
found. ).
To recover from an overpressure condition, cycle RPM4-AD power. Be sure to
correct the condition that caused the overpressure before cycling power.
