9.4

Checking the protective gas feed

NOTE

Keep the device in operation during the check.

1

Interrupt protective gas feed to the device.
The Ex control unit should signal an error state after a few minutes.

2

Start protective gas feed again.
The Ex control unit should now reset the error state and start the pre-purge phase.

9.4.1

Function test of the pressurized enclosure system

All maintenance work of the pressurized enclosure system is described in the Pressur‐
ized Enclosure Manual.

WARNING
Risk of explosion when parameters are set incorrectly

The parameters for the pressurized enclosure system are protected with a parameter
password which is only available to SICK Customer Service. Unauthorized changing of
parameters can cause an explosion with fatal consequences.

b

Never change parameters without authorization.

DANGER
Risk of explosion when the maintenance of the pressurized enclosure is incorrect

The pressurized enclosure is a central part of the ATEX certification of the device. All
maintenance work on the pressurized enclosure system is described in the Pressurized
Enclosure Manual. If work is performed which is not described in this manual, the risk
of explosion of the measuring system increases and the ATEX certification becomes
void.

b

Also observe the maintenance instructions in the Pressurized Enclosure Manual.

9.5

Swiveling out and removing the SR-unit

DANGER
Damage to eyes and skin by UV radiation

The in-situ gas measuring device GM32 emits UV radiation when the SR-unit or reflec‐
tor unit is opened during operation. Exposure of the unprotected skin and eyes to radia‐
tion is dangerous to health.

b

Disconnect the power supply of the device before opening the device.

b

Wear suitable protective goggles and protective gloves when work on the open
device with the power supply connected is performed.

DANGER
Hazard by gas escaping when the SR-unit is swiveled out

Excess pressure in the gas duct can cause hot and/or noxious gases to escape when
the SR-unit is swiveled out.

b

Swivel the SR-unit out only when you have taken suitable safety measures.

b

Set the lever on the purge air fixture to the “Close” position".
