• When the LED is seen clearly through the receiver orifice, lock the
assembly into position by tightening the four locking nuts.
• Re-attach the receiver to its purge and set the receiver gain - see
below.
• Adjust the alignment of the receiver until a maximum level is given
at the detector (Dr) - see bottom line of LCD.
• Once a maximum level at Dr has been found, secure the
alignment by tightening the locking nuts on the adjustable flange at
the receiver.
• Press ENTER to leave Set Detectors option.
• The alignment is now complete. Once this adjustment has been
made there is rarely any need for further alignment adjustment.
The optical design is capable of accommodating normal duct
movements without any effect on the operation of the device.
