` On restart after a protection device has been triggered.
` At least every 8 hours by the operator.
The inputs STO1-ENABLE and STO2-ENABLE are switched alternately
in accordance with a defined test sequence. The switch state of the
pulse disabler is available at a digital output on the PMCprotego D and
is evaluated by a safety control system.
Function test
The test sequence for the function test on the safe pulse disabler must
be implemented as shown in the following timing diagram.
Prerequisites for starting the test sequence:
` Operational readiness BTB/RTO = "1"
` Enable signal ENABLE = "0"
` STO1-ENABLE = "0"
` STO2-ENABLE = "0"
INFORMATION
The switch state of the pulse disabler is sent to a digital output
on the PMCprotego D, e.g. X3A/6, DIGITAL-INOUT1, using the
command OxMODE70.
STO dual-channel
The signal "STO-Feedback" must be evaluated.
