transceiver and the reflector. The transceiver can be oriented by tightening or loosening the panning
and tilting screws shown in Figure 6.
WARNING: When aligning the detector by means of LEDs or IPDL-152 tester and tightening
and loosening aligning screws neither tools no hands or other things must be in active zone of the
optical beam (between the lens and the reflector).
6.3.1.3.
Three various ways (and also their combinations) can be used to align the S2000-IPDL: with
the help of LEDs, by means of an IPDL-152 tester, or using a laser pointer (laser alignment tool). In the
first case no additional service equipment is used but for two other cases prior to starting work care
should be taken to equip personnel with specified instruments.
6.3.1.4.
Prior to starting specific actions to align the detector in field you are recommended to study
closely Table 5 which describes various conditions of the detector during alignment, their names which
will be used later as well as the ways of visualizing them by means of transceiver indication or on the
LCD of an IPDL-152 tester. In order to compare actual states of the detector with description for these
states in Table 5 it is advised to operate the detector in trial mode under laboratory conditions imitating
various conditions for the detector.

NOTES:
1)
xxxx stands for a digital conventional value of the received signal converted to the absolute value
based on the actual value of conditional gain and digitized value of amplifier output signal (can be
used during aligning for maximizing);
2)
yyy stands for letter identifications of states:
ОБЛ
(Very Close),
БЛ
(Close), or
ДАЛ
(Far);
3)
z stands for the sign «+» (More) or «-» (Less);
