34 Installing the XM-720 Machine Monitor
BNC Connectors
The XM-720 front panel provides three BNC connectors directly below the
bargraph meters. There are two connectors (CH1 and CH2) for monitoring
the input signals. And a third BNC connector (TACHO) for phase referencing
or triggering.
LED Indicators
The four LEDs on the front panel of the XM-720 monitor indicate the status
of the monitor. In the provided configuration files, the LEDs are configured to
function as described in Table 2.D. Use this table to help you troubleshoot
your monitor.
WARNING

Do not use BNC connectors when area is known to be
hazardous. BNC caps must be securely installed on ALL
connectors during normal operation.
IMPORTANT
Making a change to the configuration parameters may
possibly change the intended function of the LED.
IMPORTANT
The Module Fault LED will be illuminated when you first
apply power to the XM-720 monitor because the relay
associated with this LED is not configured for failsafe.
Make sure you configure your XM-720. For information on
how to configure the XM-720, see Chapter 3 on page 37.
