A picture of the secondary electronics is given.
There are 6 dip switches located on the secondary electronics
as indicated below; they are used for settings when integral
digital display is not available.
Switch 1 and 2 are used for Snap Calibration, Zero and Span
Raise/Lower and also for Damping step.
Switches 3 and 4 are used for Electronics or Transducer
replace
Switch 5 is for Write Protect mode selection
Switch 6 is for Up/Down Scale selection
Now follows a description of the operations.
ADDENDUM USE OF HARDWARE LINKS ON THE SECONDARY
ELECTRONICS
ZERO / SPAN SNAP CALIBRATION
With switches 1 and 2 down in position, ZERO and SPAN local adjustment, located
below the nameplate of the transmitter housing can be used for ZERO (4-mA point),
and SPAN (20 mA point), adjustment, i.e. range calibration.
ZERO / SPAN - RAISE / LOWER
When switch 1 is moved on in "1" position, ZERO/SPAN Raise/Lower is active.
The usage of - and + buttons on the secondary electronics causes respectively an
increment and a decrement of the SPAN value (URV); ZERO and SPAN local
adjustment under the nameplate allows ZERO value (LRV) increment or decrement.
DAMPING RAISE / LOWER
With switch 2 up in "1" position, DAMPING Raise/Lower is active.
Use - button and + button on the secondary electronics to respectively decrement and
increment the damping value.
Acceptable values for damping are: 0 - 0,25 - 0,5 - 1 - 2 - 4 - 8 and 16.
ZERO / DAMPING - RAISE / LOWER
When switches 1 and 2 are up in "1" position, both ZERO and DAMPING Raise/Lower
can be performed.
Use - button and + button on the secondary electronics to respectively decrement and
increment the damping value.
Use ZERO and SPAN local adjustment under the nameplate for ZERO value (LRV)
increment or decrement.
