CONFIGURATION SWITCHES AND JUMPERS
A two position switch is located on the main control circuit board at the right of the terminal
blocks. In units with version 1.3 or later firmware, the right switch determines the response time
of the system as detailed below. The right switch is not used on units with version 1.2 or earlier
firmware. The switch on the left selects one or two "hit" calibration as described below in the
CALIBRATION section of this document.
Left Switch:
Right Switch: UP
NOTE: These switches are read only at power up. If a switch setting is
changed, be sure to power the unit down and back up again.
Each of the logic inputs (CAL and RESET) has associated with it a two position jumper plug
located immediately behind its associated connector. These jumpers allow the inputs to be
driven by a sinking (NPN) or sourcing (PNP) device. When the jumper plug is installed on the
pins closest to the connector, the input is set up for a sourcing driver. When installed on the
two pins farthest from the connector (factory setting), the input is set up for a sinking driver, or
dry contact between the input and COM. Both inputs are active low.
CALIBRATION
The detector may be calibrated via the push-button switch on the front panel or remotely through
a switch connected between the CAL and COM terminals of the right terminal block.
The DS101 offers two modes of calibration: 1) calibrate on single nominal thickness, and 2)
calibrate on single and double thickness. Normally where double thickness discrimination is
required, the DS101 can be calibrated on a single thickness of the material to be monitored (one
press of the push button). If finer changes in thickness are to be discriminated, the DS101 may
be calibrated on two different thicknesses of the same material. The discrimination threshold is
set halfway between the two calibration points.
Calibration on Single Only (Single Hit)
Calibration on single is selected when the left configuration switch is UP. See section on
CONFIGURATION SWITCHES AND JUMPERS above.
Place a single sheet of metal to be gauged against the probe face and press the CALIBRATE
push-button. During calibration on the single thickness, the green (NO DOUBLE) indicator
flashes and the yellow (DOUBLE) indicator is off. If the calibration on the single is successful,
UP selects calibrate on single.
DOWN selects calibrate on single and double
selects standard (12 millisecond) response time.
DOWN selects high speed (2 millisecond) response time.
