The DIP switches are used to protect a user input device from inadvertently being shorted
by a relay output configuration. Set the corresponding DIP switch to the On position for
output relays, and to the Off position for input relays. The factory default state of the DIP
switches is Off (Input). DIP switch 1 is for the first relay channel and DIP switch 2 is for the
second relay channel.
The shelf-state of the output relays is normally open, meaning that when the power to the
unit is disconnected, the relays are open. During operation of the unit, the relays are
typically closed until activated by an alarm, but they can be configured either way.
The following are usage examples for an online monitoring system:

In most applications, the CSI 2600 will connect to buffered outputs of a protection system.
These modules normally have relay outputs which indicate alarm levels, or bad/failed
sensors. However, the CSI 2600 relays are different in that:

Radial Trip and Axial Thrust predicates are special methods of configuring voting logic for
relay closures, and are explained in Emerson Machinery Health Manager manuals such as
the Online Software guide (MHM-97460). These are innovations provided by the CSI 2600
system, which have value in turbo machinery applications.

(output) Bad/failed sensor indication
(output) Alarm level indication
(output) Speed level indication
(output) Radial Trip Predicate state
(output) Axial Thrust Predicate state
A CSI 2600 alarm relay state may be based upon either overall vibration value (i.e.,
the attached module) or Analysis parameter signal level (i.e., energy at 1x turning
speed, energy at 2x turning speed).
All, some, or one of the alarm indicators may be mapped to the same CSI 2600
alarm relay output. In other words, all of the "Bad/Failed sensor" signal levels may be
internally connected to a single relay. All of the "High alarm" signal levels may be
internally connected to a single relay.
