Alarm Parameters
Use the Alarm, Relay and 4-20 mA Output tab in the XM-220 Speed Module
Configuration Tool to select the type of measurement that is associated with
an alarm and to set the alert and danger threshold values.
The XM-220 provides a total of eight alarms, four per channel. Each alarm is
permanently associated with a particular measurement.
To configure the alarm parameters, follow these steps:
1. In the XM-220 Speed Module Configuration Tool, click the Alarm,
Relay, and 4-20 mA tab. You will see a screen similar to this.
2. Select the Alarm that you want to configure.
3. Enter or select the desired parameters to set up the behavior of the
alarm. This includes:
• the measurement and channel associated with the alarm
• the measurement values at which the alarm changes state
• the amount that the measurement must fall before the alarm
condition is cleared (hysteresis)
• whether to prohibit the tachometer fault during the startup period
• the length of time that the tachometer fault is inhibited after the
startup signal is received
This checkbox must be checked
in order to use the alarm.
