Key switch
The Ex protection of the Ex p safety equipment can be deactivated (key inserted in the lock) using a key switch (bypass
switch). In this manner, the analyzer can also be connected electrically without protective gas purging, e.g. for maintenance
work. Some Ex p safety equipment offers the possibility of effecting the key switch function with an operating function (key
code).
Commissioning with the key switch always requires permission of the owner or a person authorized by him. It may only be
granted if it is certain that there is no explosive atmosphere for the duration of the planned work or if the necessary
precautions against the risk of explosion have been taken (fire permission certificate).
At the end of maintenance work, make absolutely sure that the key switch is turned off again through removal of the key.
