Chapter 1 Introduction This chapter provides an overview of the XM-220 Dual Speed module. It also discusses the components of the module.
2 Introduction The module includes a single on-board relay (expandable to five), two 4-20mA outputs, and a buffered output for each input. A third buffered output is available when the module is functioning in the single redundant channel mode. This buffered output signal corresponds to the active input signal so that the machine speed can be accurately tracked regardless of which of the redundant sensors is active.
Introduction 3 • XM-220 Dual Speed Module - Mounts on the XM-941 terminal base unit via a keyswitch and a 96-pin connector. The XM-220 contains the measurement electronics, processor, relay, and serial interface port for local configuration. IMPORTANT The XM-441 Expansion Relay module may be connected to the XM-220 module via the XM-941 terminal base unit. When connected to the XM-220, the Expansion Relay module simply “expands” the capability of the XM-220 by adding four additional epoxy-sealed relays.

46 Configuration Parameters Measurement Mode Parameter The Measurement Mode parameter controls how the two sensors are used to calculate the speed, acceleration, and peak measurements. The XM-220 module operates in three different modes: • Dual Channel - This is the default mode. The two sensors are used independently to perform two separate sets of speed, acceleration, and peak speed measurements.
Configuration Parameters Channel Tachometer Parameters 47 The Tachometer parameters define the characteristics of the tachometer and determine the signal processing that will be performed on the tachometer signal. There are two instances of the tachometer parameters, one for each channel. TIP IMPORTANT IMPORTANT IMPORTANT The Channel LED will flash red when a transducer fault condition exists on the channel even if you are not using the channel.
48 Configuration Parameters Tachometer Parameters Parameter Name Description XM Configuration EDS File Utility Controls whether a small amount of current is injected into the sensor wiring to help detect transducer faults of passive magnetic sensors. Enable Bias Current Bias Current Passive magnetic sensors are unbiased and provide no inherent fault detection capability.

DeviceNet Information 79 • The ADR scanner can not download the configuration data to an XM module if the module has a saved configuration in its non-volatile memory. This happens because the saved configuration is restored and the module enters Run mode when the power is cycled. (Configuration parameters cannot be downloaded while an XM module is in Run mode.) XM modules must be in Program mode for the ADR configuration to be downloaded and this occurs only when there is no saved configuration.
80 DeviceNet Information – All SU/CD Trend related parameters – Custom Assembly structure (see page 59) • The ADR and trigger group functions cannot be used together. A module can have only one primary master so a module cannot be both configured for ADR and included in a trigger group. The ADR scanner must be the primary master for the modules configured for ADR. The XM-440 Master Relay module must be the primary master for modules included in a trigger group.

Glossary alarm An alarm alerts you to a change in a measurement. For example, an alarm can notify you when the measured vibration level for a machine exceeds a pre-defined value. Automatic Device Replacement (ADR) A means for replacing a malfunctioning device with a new unit, and having the device configuration data set automatically. The ADR scanner uploads and stores a device’s configuration.
Glossary 112 current configuration The current configuration is the most recently loaded set of configuration parameters in the XM module’s memory. When power is cycled, the current configuration is loaded with either the saved configuration (in EEPROM) or the factory defaults (if there is no saved configuration). In addition, the current configuration contains any configuration changes that have been downloaded to the module since power is applied.
Glossary 113 Help window A window that contains help topics that describe the operation of a program. These topics may include: • • • • An explanation of a command. A description of the controls in a dialog box or property page. Instructions for a task. Definition of a term. MAC ID See node address. master device A device which controls one or more slave devices. The XM-440 Master Relay module is a master device. node address A DeviceNet network can have as many as 64 devices connected to it.
Glossary 114 Program mode The XM module is idle. Typically this occurs when the module configuration settings are being updated with the XM Configuration program. In Program mode, the signal processing/measurement process is stopped. The status of the alarms is set to the disarm state to prevent a false alert or danger status. Run mode In Run mode, the module collects measurement data and monitors each measurement device.
