Installation
6.
Secure the units to the brackets with the three screws M 5 x 10 mm and washers. To
do so, move the running nuts.
You can then perform a fine adjustment in the horizontal and vertical planes using the
three lock nuts (self-locking).
7.
Align the units as described in
Chapter
4.3.3 Alignment of the ISD.
Device units in fixed and mobile stations (variable link)
For large distances the units have to be mounted in such a way, that in case of vibrations
the cone of IR light will reach the receiver area in the opposite station (fixed) in the middle
(and the same in the other direction). The vibrations can be caused by accelerating and
stopping the mobile station.
Ø
Prefer to mount both units vertically using the angled flange or the fixed plate of the
three-point brackets. With a stabil base this position provides an operation poor of
vibrations.
Ø
If the units can only be mounted horizontal (due to small place in the locations), use the
4 drilling holes on the fixed plate of the three-point bracket.
4.3.2
Mounting the AMS 50 Connection Module
Ø
Mount the connection modules near the units. The maximum distance between the
AMS 50 and an unit should not exceed 10 m, in particular when using the ISD 230 with
the RS 232 data interface.
For detailed informationen on installing and wiring, please refer to the operating
instructions
“AMV/S 50 Connection Module“
(order no. 8 008 294, English edition)
.
4.3.3
Alignment of the ISD
Optical adjustment aid
The optical alignment aid facilitates exact alignment of the devices. Crosshairs, which can
be used to focus on the opposite unit, are visible in the opening at the top of the device
(
Fig 4-4
). At large distances, it also may be useful to attach a torch (with a tape) to the
opposite unit.
Ø
The units should be only be aligned (in particular when using the optical adjustment aid)
when the ISD system is
switched off
.
This is the only way to prevent direct eye contact with the IR beam (eye protection).
