1. Commissioning from a Safety Point of View
In order to put the Mobile Panel device into operation, the E-stop function must first be
acknowledged using the key switch. This causes the E-stop safety relay to begin monitoring the
E-stop button. If this is not operated and the enable switch is pressed in the enable position or a
safety door on the system is closed, then the main circuit contact, which has to be effected via
external mandatory safeguards, is closed.
When the E-stop button is actuated, it becomes engaged. The E-stop monitoring device then
shuts down the machine or system. A quarter turn clockwise releases the E-stop button once
again. Releasing the E-stop button may not cause the machine to automatically begin running
again. The E-stop action must first be acknowledged with the key switch before the machine or
system can be put back into operation. Bypassing the key switch will be detected by the
monitoring device.
The machine's safety circuit remains interrupted as long as the 3-step enable switch has not
been pressed or the assembly's safety door has not been closed. The enable switch has three
steps, but the enable signal is only passed on when it's set in the middle position. In other words,
the enable switch must be pressed to the middle position in order for the Mobile Panel to carry
out user commands (see also "Functionality" in "Enable Switch", on page 60).
1.1 Intended Use
The Mobile Panel device may only be used for the applications described in section
"Introduction", on page 21.
Information:
The responsibility for the correctness and functionality of the wiring, adherence to
prescribed standards, and safety engineering rests solely with the project
engineers.
