DESCRIPTION
The Avtron Model XP5 SMARTSafe™ sensor is an incremental
encoder for hazardous atmosphere applications (also known as
tachometer or rotary pulse generator), allowing operation down to zero
RPM. It provides a specific number of electrical Pulses Per Revolution
(PPR) that are proportional to a shaft’s revolution. The XP5 SMARTSafe
sensor is a bearingless, couplingless, modular design, providing
unequaled reliability and mechanical performance.
An XPH encoder consists of multiple parts: a rotor and a removable
XP5 sensor module designed to be imbedded within or mounted on
OEM machines and an optional flange-mounting stator housing and
optional rotor mounting/riser shaft.
The XPH utilizes XP5 magnetoresistive sensors. This proven
technology is ideal for rugged environments since it is immune to
many contaminants that cause optical encoders to fail. All of the XP5
electronics are potted, providing full protection against liquids.
The outputs are protected against short circuits and wiring errors. An
Avtron XPH SMARTSafe encoder has a two-phase output (A,B) 90° out
of phase, with complements (A–, B–), (A Quad B Output), and a marker
pulse with complement (Z, Z–).
The XP5 removable sensor assembly has a diagnostic package
that includes Adaptive Electronics and a Fault-Check LED. With this
package, the SMARTSafe encoder can maintain itself, and let you
know if there is a problem before the problem causes unscheduled
downtime.
ADAPTIVE ELECTRONICS
A perfect duty cycle consists of a waveform whose “high” and “low”
conditions are of the same duration (50%/50%). It is possible over time
for the duty cycle and edge separation to change due to component
drift, temperature changes, or mechanical wear. The Adaptive
Electronics extend the life of the XP5 by constantly monitoring and
correcting duty cycle and edge separation over time.
INSTALLATION
WARNING
Installation should be performed only by qualified
personnel. Safety precautions must be taken to ensure
machinery cannot rotate and all sources of power are
removed during installation.
Refer to the following attached installation drawing
XP5CRT05
for
installation information appropriate for specific hazardous locations.
NOTE
The equipment is intended for a fixed installation and
should be mounted so as to avoid electrostatic charging.
The XP5 is not considered as a safety device and is
not suitable for connection into a safety system.
It is the responsibility of the end user to ensure that the XP5 and XPH
encoder is selected correctly for the potentially explosive atmosphere
in which the equipment is to be put into service.
