Safety Related Parts of the Control System (SRP/CS)
The Niftylift control system has been designed and validated according to the required standards. The
table below lists the safety related parts of the control system and the level to which they have been
approved.
The performance level (PL) of each SRP/CS is specified by BS EN 280:2013+A1:2015 section 5.11

PREVENT TRAVEL ABOVE INCLINATION LIMIT
The inclination interlock or Tilt System is PL c in accordance to with
BS EN ISO 13849-1:2015
as
required by BS EN 280:2013+A1:2015.
1.
The limits of the safety-related parts to the category selected and any fault exclusions;
The tilt interlock is only active when the telescoping booms are lifted up out of the stowed position.
An inclination sensor on boom 1 measures the angle of the machine chassis.
Proper maintenance and daily safety checks to be observed
The inclination sensor cannot be overridden to bypass the tilt system other than by demounting the
switch with the use of tools.
Reasonably foreseeable misuse
If the inclination sensor is removed or if it is not maintained in accordance with the appropriated
documentation the tilt system may not function in compliance with the requirements as a PL c device.
2.
The limits of the SRP/CS and any fault exclusion, for which, when essential for maintaining the
selected category or categories and safety performance, appropriate information (e.g. for
modification, maintenance and repair) shall be given to ensure the continued justification of the fault
exclusion(s);
