Connecting the Setpoint Multiplication Switch (XM-161 &
XM-162)
You can configure the Direct Vibration modules to multiply the alarm
setpoints, or inhibit the alarms during the start-up period. This can be used to
avoid alarm conditions that may occur during startup, for example, when the
monitored machine passes through a critical speed.
Setpoint Multiplication (startup inhibit) can be initiated and terminated using a
DeviceNet command (XM Service) or by a closure of a physical contact
(XM-161 and XM-162 only). Refer to XM Services on page 85 for more
information on XM Services.
To activate the switch, the Setpoint Multiplication input terminal should be
connected to ground/common. The XM-162 module provides a dedicated
terminal for this purpose. However, the XM-161 module does not. Therefore,
the input terminal must be wired to any of the XM-161 module’s Signal
Common or 24V Power Supply GND/COM terminals.
Wire the Setpoint Multiplication switch to the terminal base unit as shown in
Figure 2.13.
ATTENTION
If the Setpoint Multiplication switch cable exceeds a length
of 30m, then the cable must be shielded with the shield
earth grounded.
