Switch-off Procedure
Depending on the type of device activation and how it is integrated (e.g. manual or automatic) in the
cleaning plant, the switch-off procedure must be integrated and the following instructions must be
observed when switching off.
WARNING
Risk from sudden, unforeseeable or unauthorized reactivation of the device (e.g.
triggering of a start command as a result of incorrect operation of a start-up control
device)!
There is a risk of death or severe physical injury.
Before performing any disassembly, maintenance, repair or cleaning work on the device,
it is essential to carry out the following work steps in the specified order:
Switch-off procedure
1.
Interrupt the supply of cleaning medium (e.g. slowly close the shut-off valve or ball cock).
Check that the supply of cleaning medium is stopped and there is no media
pressure at the device.
2.
Safeguard the supply of cleaning medium to prevent sudden, unforeseeable or
unauthorized reactivation (e.g. lockable switch/shut-off elements).
Check that any supply of media is reliably prevented and insert dummy disks if
necessary.
Comply with a cooling phase for media temperatures above 80 °C.
Make sure that the cleaning device and supply line for the cleaning medium have
been completely drained (waiting time at least 60 s).
3.
Disconnect the power supply to the higher-level plant/the device.
Check to make sure that the power supply is disconnected and that there is no
voltage at the sensors.
Safeguard the power supply to prevent sudden, unforeseen or unauthorized
reactivation (e.g. lockable switches)
4.
Depressurize the container against the ambient pressure.
Safeguard the supply of steam or other media that affect the pressure to prevent
sudden, unforeseen or unauthorized reactivation (e.g. lockable switches/shut-off
elements).
Make sure that the pressure inside the container matches the ambient pressure.
