(i) Check that, after the machine has been
stopped by the actuation of the CKP/Solo, it
is not possible for the dangerous parts to be
set in motion until the CKP/Solo has been
cleared, the reset button has been operated
and released, and the machine start control
has been re-operated.
(j) Check that the removal of power from the
CKP/Solo prevents further operation of the
machine. It should not be possible for the
dangerous parts of the machine to set in
motion until power has been restored, the
reset button has been actuated and released,
and the machine start control has been
actuated.
(k) Check that the CKP/Solo operates over
the whole active area by walking, 'heel to toe',
over the whole area in two directions, as
shown in Figure 10.
(l) Examine the stopping performance monitor
(if fitted) to ensure that it is fitted and functioning
correctly. Ensure that the means by which the
stopping performance can be assessed by the
operator is indicating correctly.
(m) Test the muting arrangements (if fitted).
Ensure that the muting is only possible during
non-dangerous operation and ensure that the
safety level of the muting device is at or above
that of the safety mat but never below.
(n) Examine brakes and clutches (if fitted) as
recommended.
NOTE: No stopping performance monitor
or muting facilities are provided with the
Tapeswitch safety mat system and there is no
means provided for the connection of such
devices to the system. These devices may
however have been provided elsewhere in the
machine control system.
