Instant in time of the test stop

The shutdown paths must be tested (forced checking procedure) at a suitable in-

stant in time, refer to Chapter 5.3 "Forced checking procedure".

The machine manufacturer should define the "test shutdown paths" time in an

appropriate "test block".

If the brake control is enabled, then when the test stop is initiated, the brake is

also controlled.

Prerequisites for the test stop

S At the start, the pulses must still be enabled; further, it is not permissible that

SH is selected at the start.

locked (to stop them falling).

The test stop can be carried out independently of the status of the standard pulse

cancellation.
