Power supply connections can be made in the PWS100 24 Vdc/12 Vdc power

Din rail contacts are mounted inside the power supply enclosure that allows
connection to the two power supplies (see Figure 6-11).

6.3.8 Start-Up Testing
On start-up the PWS100 will run internal diagnostic tests and check the status
of any connections to the instrument.
6.3.9 Initial Settings
Initially the PWS100 will be set up with a series of default options set. These
can be altered by entering the command mode of the sensor.
6.3.10 Load Factory Defaults
To load the factory default settings (retaining only the time, date and
calibration values) power down the sensor move dip switch 8 to position 1 and
power up the sensor. Once powered switch dip switch 8 back to position 0.
This removes the password and all other user entered values.
6.3.11 Lubricating the Enclosure Screws
The PWS100 enclosure screws should be lubricated with a suitable anti-seize
grease (often copper loaded) to protect the threads from corrosion. This should
be reapplied when resealing the enclosure at regular intervals, normally after
