Release 7/2009 Ver. 1.0 Technical Manual: GS-120 Light Curtain Systems
This makes replacement of a unit much easier as
the new unit will have the brackets already in the
correct position. The position of the clamps on the
units is shown in Figure 23.
The set screws may not be completely tightened in
the supplied position. These set screws must be
fully tightened before proceeding with the
installation. (A 2 mm Allen wrench is supplied for
use in tightening the brackets.) If these brackets are
not properly secured, the emitter and receiver units
may shift causing nuisance tripping, a false lock-out
condition and/or a potential safety hazard.
Four wall brackets are supplied with each system
together with the 8 self-tapping screws needed to fix the
wall brackets to the clamp brackets. The wall bracket
dimensions are shown in Figure 24.
The alternative mounting arrangements which these
brackets facilitate are shown in Figures 25, 26, & 27.
The internal construction of the units is such that they
can withstand normal levels of vibration and shock. In
situations where the vibration of the machine cannot be
reduced to normal levels, vibration proofing mountings
should be used.
