Programming/Diagnostic Mode
To view or edit programmed input and output ranges and/or perform system diagnostic tests the
programming/diagnostic mode is used. Programmed input and output options are retained by the DSV-
100 indefinitely until edited. In the programming/diagnostic mode the input and output range options are
first presented for viewing or editing after which the DSV-100 performs a system response and leak test.
WARNING!! The DSV-100 will pressurize the system and perform a response and leak test after
the input and output range options are viewed or edited. This can cause unexpected motion, flow or
other physical response. Always use caution when using the programming/diagnostic mode and be
aware of the results it can produce.
To access programming/diagnostic mode, the SET-key must be pushed before and held in while power is
applied to the DSV-100. With the SET-key held in, apply power to the panel and/or plug in the electrical
connector to activate the converter. The DSV-100 will briefly show a software revision number before
entering the programming/diagnostic mode.
View/Edit Input Option - The display will blink
ir (input range) five times and then display the
currently selected input option number for 2-3 seconds. If the desired option is displayed, do nothing and
wait a few seconds for the display to blink
or (output range). If the displayed number is not the desired
input option, press the MODE-key immediately. The display will again blink ir (input range) five times
and display the next input option number. If the displayed number is not the desired input option, press
the MODE-key and repeat the procedure until the desired option number appears. When the desired
option is displayed, do nothing and wait a few seconds. The DSV-100 will save the last displayed
number as the input option and the display will then blink
or (output range).
View/Edit Output Option - The same procedure is used to
s elect one of five output range options. The
display will blink or (output range) five times and then display the currently selected output option
number for 2-3 seconds. If the desired option is displayed, do nothing and wait a few seconds for the
display to blink
rP (response test). If the displayed number is not the desired output option, press the
MODE-key immediately. The display will again blink or (output range) five times and display the next
input option number. If the displayed number is not the desired output option, press the MODE-key and
repeat the procedure until the desired option number appears. When the desired option is displayed, do
nothing and wait a few seconds.
The DSV-100 will save the last displayed number as the output option
and the display will then blink rP (response test).
Response Test - Once the input and output options have been viewed or edited the DSV-100 performs
two diagnostic tests, a response test and a leak rate test. The first is a dynamic response test and the
display will blink
rP (for response test). The DSV-100 will first vent any pressure on the outlet then
pressurize the output to the maximum pressure dictated by the programmed output range for 100
milliseconds, read the system response, and display the result. Results appear as a number from 0 to 100%
with 100% indicating the best possible response. Responses will vary with length of hose and actuator
volume. Responses above 80% can be considered very good, a response below 50% indicate a low
response system
. Lower responses can be due to long hoses, high volume components, excessive Cv
requirement, or may indicate a leak or malfunction.
