vibration level drops below the associated setpoint for
more than about 1 second, the associated relay will de-
energize and the alarm LED will turn off. The alarms can
also be set for latching operation by installing shunts on
jumpers E11 and E12 on the Alarm module circuit board.
Latched alarms may be reset by closing the RESET (RST)
and COMMON (COM) contacts at the top of the unit. This
may be done with an external switch, dry contact relay, or
by shorting the terminals together by hand.
Important - Do not apply voltage to either the RST or
COM terminals.
If several monitors are mounted together, the RST
terminals may be daisy-chained together and switched to
COM (system common) as a group.
Trip Multiply
The alarm module provides a trip multiply feature. This
feature allows the user to temporarily double (standard)
or triple (jumper selectable) the normal setpoints during
periods of normal high vibration, such as start-ups. To
actuate the trip multiply feature, the Tx terminal at the
top of the alarm module must be closed to the adjacent
COM terminal. This may be done with an external switch,
dry contact relay, or by shorting the terminals together by
hand.
Important - Do not apply voltage to either the Tx or COM
terminals.
If several monitors are mounted together, the Tx
terminals may be daisy-chained together and switched to
COM (system common) as a group.
