Description
98
Save to User Default Area
When set to a value of 1, the unit will store all adjustable
parameters to the user default area� The user default area is
intended to be a location where an OEM or integrator can store
settings specific to their application� Using this, an OEM can easily
refresh their custom settings in the field if an end-user accidentally
reconfigures the unit unsuccessfully� Another common use for this
area is testing and initial setup� The user can store known-good
settings here and easily experiment without the fear of losing the
optimal configuration�
Note: Do not save a program that is all default values with no
changes� This will cause the display to dim and you will not be
able to see the display information� If this occurs, a hard reset is
required� Press and hold the Enter and Down arrows at the same
time, and cycle power�
99
Restore from User Default Area
When set to a value of 1, the unit will restore all adjustable
parameters from the user default area� See parameter 98 for
additional information�

Problem
Possible Cause
Solution
Display is blank
1–Power not applied
2–Defective unit
1–Using a volt meter, verify that a voltage between 85
and 265 VAC is measure between the L and N terminal
block positions�
2–Contact technical support for additional help and
instructions�
Display is dim
Display intensity parameter is
too low
Increase the display intensity parameter to cause the
display digits to become brighter�
“-S1-” or “-S2-”
displayed
Switch S1 or S2 is active
Remove S1 or S2 input� Refer to Parameter 30 and 35 for
information on settings�
“LOC” displayed
Parameter 30 or 35 is set to 7
Change input state of S1 or S2; or reprogram Parameter
30 or 35
Does not provide
proper output
Jumpers in wrong position
Verify jumpers are properly set for desired operation
(see “Device Configuration” on page 9 and “Mode of
No output if either JP3 or JP4 are in the wrong position�
JP1 in wrong position:
• For Scaled Mode, neither current nor voltage output
will be properly scaled with the intended input�
• For Generate Mode, it will have no effect� Check all
connections to make sure they are secure and not
reversed�
• For Voltage Output Mode, check that R9 was properly
set for the Maximum output desired (100% of display
with the user hardware connected directly to the V-out
terminals)�
If Parameter 10 Value = 1, then the GSDA-DP-S is in
Generate Mode and there will be no output change for a
change in Signal Input, only for Keypad entry�
If Parameter 10 Value = 2, then the GSDA-DP-S is in
Scale Mode and the output will change for both a
change in Signal Input and Keypad entry�
If JP1, JP3, or JP4 are missing or on one pin, then it
will have either minimal value output or none at all
depending on output type configuration�
Please recheck all settings and jumper configurations�
