Parameter Options
The software presents one read-only parameter (Actual Vibration) and several parameters that can be
programmed to optimize performance of the Smart Switch. At any point during the programming process, the
values can be changed between imperial and metric measurements by clicking the Units dropdown in the top
navigation menu and then selecting the appropriate measurement type.

Description
Actual vibration (ips pk) being sensed by the switch at
time when Read Parameters button is clicked.
Capability to determine and set the alarm threshold value
automatically by the Smart Switch based on the actual
vibration level measured by it. For more information about
the MAVT™ feature, see page 16.
Vibration level at which the relay will change state.
Percentage that actual vibration must fall below the alarm
threshold in order for a non-latching relay to automatically
reset itself. Hysteresis prevents a relay from continually
changing states when the vibration level is hovering
around the alarm threshold level.
State in which the relay stays when not tripped.
How the relay operates once actual vibration falls below
the alarm threshold.
Latching: Relay to latch or stay in the alarm state
until manually reset regardless of the vibration
level.
Non-Latching Relay automatically resets once the
vibration level falls below the alarm threshold
(hysteresis) level.
Specified time period immediately after power is applied to
the switch during which the relay will not trip regardless of
the vibration level. Prevents a relay trip during high
transient vibration levels that may occur during a normal
machine startup.
Specified time period for which actual vibration must
constantly exceed the Alarm Threshold before the relay
changes state. Prevents a relay trip as a result of a short
transient spike in vibration level that may not even be
caused by a machine fault.
Specified time period immediately after power is applied to
the equipment being monitored during which the relay will
not trip regardless of vibration level.
Time period during which vibration is ignored.
Maximum vibration ignored during the time period.
Calculated as a multiple of the Alarm Threshold.
Minimum vibration level that, once surpassed at
equipment startup, triggers the countdown of the Startup
Delay Time Period.
