The Teach-in factor,
is the factor by which the vibration amplitude currently being measured is multiplied,
when by pressing the
Teach-in
(Figure 2) button, the alarm limit is automatically set. The Teach-in button is
accessible without opening the casing, you simply need to remove the screw cap. It is useful for setting the
alarm limit when there are no specific values available.
Under
Switch Output
you can determine the switching of the relay output. First of all, you can choose
whether the relay should open or close when the warning and alarm limit are exceeded.
Power-on delay
is
the duration of time between the power supply being connected and the relay being activated. It eliminates
false alarms during the settling process.
Delay
is the period of time which occurs between the alarm limit be-
ing exceeded and the relay switching. It helps prevent short shock pulses.
Hold time
is the time during which
the relay retains its switch status, after the vibration amplitude has dropped below the warning and alarm
limit again. It guarantees a minimum duration of time for the signaling of alarm events.
The programmed settings are immediately transferred to
3&(
VS10. They can additionally be saved to a file
(
Save
). The file contains the ending
.xml
. By pressing
Load
you can reload the settings.
Set defaults
restores
3&(
VS10 to its factory settings.
Installation and Operation
Typical attachment points for
3&(
VS10 are rigid components such as, cast iron cases, bearing houses, profiles
and foundations. Flexible components like thin sheet metal or plastic parts are unsuited. The
3&(
VS10 can be
mounted in the vertical or horizontal direction, preferably be means of the supplied M8 screw. It is sufficient
to tighten the screw by hand, without using a tool.
The cable is lead-in through a waterproof cable gland. It can be used for multi-wire cables with diameters be-
tween 3.5 and 5.5 mm. The power supply (5 .. 30 V / <100 mA) is connected to the screw terminals
0V
(neg-
ative pole) and
+U
(positive pole) (Figure 2). It is protected against reverse polarity.
3&(
VS10 contains a PhotoMOS relay without mechanical contacts. The relay contacts are located on the two
right hand terminal pins. Please pay attention to the limit values for electrical load.
The alarm status of
3&(
VS10 is indicated by the four LED's on the outer casing. If all LED's are lit green, there
is no warning or alarm. If two LED's are lit red and two green this indicates that the warning limit has been
exceeded. If all LED's are lit red, the alarm limit has been exceeded.
