Setting Up the SKF Multilog WVT

Commissioning Mode

Commissioning Mode
Normally, the bias voltage, temperature and tachometer speed are only updated in the
unit after the first scheduled data collection. The commissioning mode allows you to
check the correct connection of the sensors and the tacho device immediately after they
are connected, independent of the collection schedule.
To put the SKF Multilog WVT into Commissioning Mode, insert a jumper into position
JP2 on the left side of the main board, and then press the LCD display push button on
the outside of the unit. The sign-on message COMMISSIONING appears in the display
title bar at the top. The device then reads the bias voltage and temperature on each
channel in turn.
A correctly connected sensor should read 1.5 V in the BIAS column and the correct
temperature in the ºC column. A value of 3.0 V in the BIAS column indicates that the
sensor signal is open circuit. A value of approximately 55 ºC indicates that the
temperature input is not connected.
If a tacho device is connected and the machine is running, machine speed will be
reported under RPM. A value of zero indicates that no pulses are being received. To
check a tacho device manually when a machine is not running, TRIG HIGH or TRIG LOW
is reported on the screen when a target is absent or sensed by the tacho sensor. Note
that the Namur sensor requires a ferrous metal object.
IMPORTANT: When you are done commissioning the sensors, be sure to
remove the jumper from position JP2. This will return the SKF Multilog WVT to
normal operating mode.
WARNING! After commissioning, remove power to the SKF Multilog WVT and
do not apply power until it is time to provision the device into active service in the
network. This will prevent incorrect initialization before the global configuration is
specified by the user and conserve the battery (if battery powered).
