MSR41 units can only achieve their
function as a safety controller module, if
the instructions given in this instruction
manual and the within mentioned
documents are exactly followed, as well
as consulting the valid laws and
regulations at the time of installation.
Should these instructions not be carefully
followed, serious injury or death may
occur. The installer or system integrator
will be fully responsible for a safe
integration of this product.
This instruction manual is to be used in
conjunction with the MSR41 base
module. It must be kept accessible
together with the other machine
documentation during its entire life cycle
for all personnel responsible for assembly,
installation, operation and maintenance.
Introduction
MSR41 is a extremely compact safety module. This main controlling
module allows the connection and the control of the compact
GuardShield Micro400 safety light curtain systems (Figure 1).
