Receiver
Fully tighten the retainer ring on the receiver
module, then tighten the set screw to prevent
the ring from being turned.
7. When all equipment has been properly
installed, ensure that system alarms are
appropriately bypassed and apply power to
the system.
8. Per form the alignment procedure as
previously described in this manual.
IMPORTANT
If the LS2000 module had an aperture
installed, install the aperture after
performing the alignment procedure
(install aperture on the transmitter, not on
the receiver). If the separation distance
is between 5–40 meters and signal
saturation is indicated after completion
of the Basic Alignment procedure, an
aperture will be required (even if no
aperture was originally installed). Refer
to the “Aperture Kit for Short Range
Applications” section of this manual for
complete information regarding apertures.
9. Perform a zero calibration of the detector.
10. Upon completion of zero calibration, verify
proper operation by performing an “optical
test film test” and also a “beam block test”
(see steps 20 and 21 in the “Basic Alignment
Procedure” section in this manual).
NOTE
Replacement receiver modules are
furnished from the factory with default
configuration settings. If the LS2000
system has had any configuration
changes in the field, the new receiver
will require changes to configuration
parameters using a HART communicator,
a FlexVu UD10 display unit, or Modbus
communication.
11. Restore system alarms (remove bypass).
