POWERING YOUR GAUGE
The DFS II-R-ND requires a sensor for it to per-
form as a force or torque gauge. The DFS II-R-ND
without a sensor attached will indicate that a sen-
sor must be fitted.
If an SLC or STS sensor is not connected to the
gauge, the gauge will display “Int Cal Error”, “Ext Cal
Error”, “Configuration Error”, “Defaults loaded” or “No
Sensor”.
The gauge will then ask for a Calibration Date. Power
down the gauge and connect the sensor to allow for a
proper instrument start,
POWER UP WITh STS SENSOR
When you connect a calibrated STS Sensor to the
DFS II-R-ND, the gauge will display the STS model
number, representing the capacity on the power up
display. The gauge will perform as a torque gauge.
IMPROPER SENSOR CONNECTION
If you disconnect the sensor from the gauge with
power still ON, the gauge will display “No Sensor”.
If you connect a new sensor to the DFS II-R-ND
with power still ON, the gauge will display the last
sensor that was recognized at power up. It will not
recognize the new sensor, since the sensor’s
characteristics are transmited to the gauge firmware
at powerup. If the last sensor that was attached to
the gauge before powering down was an
SLC-0100, and you connect an SLC-0025 with
power still ON, the gauge will perform incorrectly
and act as if the SLC-0100 is connected.
CONNECTING A SENSOR
The SLC or STS Sensor must be connected to
the DFS II-R-ND gauge with the power OFF. The
gauge does not permit “hot swapping” of sensors,
connecting new sensor with the power ON. The
DFS II-R-ND must go through the power ON rou-
tine with the sensor attached so that it can obtain
the sensor characteristics. The sensor character-
istics, e.g. sensivity, calibration data, etc. is stored
on a printed circuit board in the connector for the
sensor.
