MCT Module Configurations.
MCT modules can be ordered as stand alone Monitors by
adding the suffix "A" to the basic model number (i.e.,
CMSS530A or CMSS590A). When ordered as a stand
alone monitor, the unit includes an alarm module front
panel and output relays that can be jumper configured
for either latching or non-latching operation. The ALERT
or DANGER LED will turn "ON" and the corresponding
relay will actuate whenever overall vibration levels exceed
the corresponding setpoint for more than a preset delay
time (jumper selectable). The alarm module has a front
panel accessible BNC connector and associated selector
switch for reading the analog current vibration level (CV)
or alarm setpoints (A or D) with a standard digital
voltmeter. The alarm module also provides a transducer
OK relay contact, and a trip multiply function (Tx). Trip
multiply allows the alarm levels to be temporarily
