Leak Test - After a brief display of the response test result, the display will blink Lr (for leak rate) while
the DSV-100 performs a leak test. The DSV-100 pressurizes the output to the maximum pressure dictated
by the programmed output range and then reads the pressure for 2-3 seconds to determine if the system is
holding pressure or at what rate it is depleted. The leak rate is displayed as a number from 0 to 100% with
0% indicating a completely open output and 100% indicating that there is no leakage. A result less than
100% indicates that pressure has diminished over time likely due to a leak in a hose, fitting, diaphragm or
actuator. The leak rate result will be displayed for a few seconds and then the DSV-100 will then revert to
the AP display (Actual Pressure) and begin operation according to the programmed options.
Manual Operating Mode
When the manual operating mode is selected the default setpoint is 4 psi and the output range is 0-100 psi.
Whenever power is applied or after programming/diagnostics are completed the display will revert to the
AC display (Actual Pressure). As with analog input modes, the MODE-key is used to view the AC
(actual pressure), SE (set-point), or di (difference) displays. The two touch-keys are used to increment
(MODE-key) or decrement (SET-key) the setpoint value. To adjust the setpoint, press the SET-key
causing the display to blink
SE (set) for 1-2 seconds. The DSV-100 looks for a key to be pressed before
SE stops blinking so quickly press and hold the MODE-key to increment the setpoint, or press and hold in
the SET-key to decrement the setpoint. Once either key is released, the SET-key must be pressed again
change the setpoint. In manual mode the DSV-100 will not retain the setpoint if power is removed and the
setpoint will always revert to four psi whenever power is applied or after programming/diagnostics are
completed.
