Use Of Qualified Personnel - Pilz PMCprotego D.48 Operating Manual

Safety
The safety function "safe torque off" corresponds to a category 0 stop (uncontrolled stop) in
accordance with EN 60204-1.
Improper use STO
The safety function STO may not be used when the drive is to be stopped for the following
reasons:
} Cleaning, maintenance and repair work, long interruptions in operation
Remove the voltage from the entire plant and secure it (main switch).
} Switching off the energy supply of the servo amplifier
(see standard EN 60204, emergency switching stop).

Operating Manual PMCprotego D.48, PMCprotego D.72
1001735-EN-04
Enable (switch off the voltage.)
Also disconnect the auxiliary circuits.
Secure against reconnection
Verify that the system is dead
Carry out earthing and short circuiting
Provide protection from adjacent live parts.
DANGER!
Risk from rotating motor after STO has been triggered!
The safety function STO switches the motor to torque-free. On motors
without a safe holding brake, moving parts present a threat to life.
Use an additional mechanical measure to block the drives safely (e.g. with
the motor holding brake), particularly with suspended loads.
DANGER!
Risk from non-safety-related activation of the motor holding brake!
Activation of a holding brake via output BR+/BR- of the servo amplifier is not
safety-related. Depending on the application, hazardous motor movements
may cause serious injury or death.
A motor holding brake activated by the servo amplifier alone is not suitable
for personal protection.
Block the drive through an additional mechanical holding brake, which is ac-
tivated safely (e.g. with the safety card PMCprotego S1-2).
