3.4 INITIAL CHECKING AND ALIGNMENT
The procedure for alignment is described below.
Apply power to the GS-120 system.
The amber indicators on the emitter and receiver units
should be lit. If either of the indicators is not lit, check
the wiring.
The yellow indicators on the emitter and the receiver
units should be in the off state. If either of these two
indicators is flashing, there is a fault, contact your
Tapeswitch distributor. If the yellow indicator on the
emitter unit is on constantly, check the wiring as
described in sections 3.3.2 and 3.3.3.
The green indicator on the receiver unit should be lit, if
not, adjust the units into general alignment until the
green indicator comes on.
Adjust the units to optimum alignment as follows:
1.
Slowly turn the emitter unit clockwise until the green
indicator on the receiver unit goes off and the red
indicator comes on. (Note this position.)
2.
Then turn the emitter unit counter-clockwise, again
until the green indicator goes off and the red indicator
comes on. (Note this position.)
3.
Set the emitter at the center of the two noted
positions.
4.
Repeat steps 1, 2 and 3 but this time turning the
receiver unit.
Using the test piece provided, obstruct the curtain. On
the receiver unit the green indicator should go off and
the red indicator comes on.
Move the test piece in and out of the curtain several
times and check that the indicators change state
appropriately each time.
See section 5.2 of this manual if the system does not
function as described above.
The installation of the machine can now be completed.
Before putting the machine into use, the complete
system (i.e. the machine and all its safeguarding
devices) should be commissioned by qualified personnel
and, as a minimum, the commissioning checks
described in section 5.1.1 of this manual should be
performed.
Periodic checks in accordance with section 5.1.2 should
be carried out at the prescribed intervals. Daily checks
to be performed on the GS-120 system are detailed in
section 5.1.3 of this manual. In some cases there are
specific statutory requirements concerning the
examination, inspection and test of a machine and its
safety devices. It is for the user to determine if such
requirements exist for the machine in question and to
ensure that those requirements are met.
