7. When all equipment has been properly
installed, ensure that system alarms are
appropriately bypassed and apply power to
the system.
8. Perform 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 and 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 in 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).
dEvicE REpaiR and REtuRn
The LS2000 IR Hydrocarbon Gas Detector is
not designed to be repaired in the field. If a
problem should develop, first carefully check for
proper wiring, programming and calibration. If it
is determined that the problem is caused by an
electronic failure, the device must be returned to
the factory for repair.
Prior to returning devices, contact the nearest
local Detector Electronics office so that a Return
Material Identification (RMI) number can be
assigned. A written statement describing the
malfunction must accompany the returned
device or component to assist and expedite
nding the root cause of the failure.
Pack the unit properly. Always use sufficient
packing material. Where applicable, use an
antistatic bag as protection from electrostatic
discharge.
NOTE
Inadequate packaging that ultimately
causes damage to the returned device
during shipment will result in a service
charge to repair the damage incurred
during shipment.
Return all equipment transportation prepaid to
the factory in Minneapolis.
