2Safety

2.1 Correct use

The DMT on-site measurement transducer is designed exclusively for the

•measurement of pH value resp. redox potential

•measurement of temperature

•display of measured variables

•production of an output signal

It is prohibited to use the device for any other applications or to modify it

in any way!

The device must not be used outdoors without added protection (housing,

weatherproof cover).

2.2 Safety guidelines

CAUTION

•The device must not be used in a possible explosion

area.

•The DMT must be operated by trained and authorised

personnel.

IMPORTANT

•The system must be suitably equipped and configured to

prevent overdosing of hazardous materials due to probe

failure.

•The DMT has no on/off switch. It starts to function as soon

as it is connected to a power supply.

3Storage and transport

Store and transport the DMT in the original packaging.

IMPORTANT

•Protect the DMT from damp and the effects of chemicals

even when packed.

Ambient conditions for storage and transport:

Temperature: -20 °C to 70 °C

Humidity: max. 95 % relative humidity,

non condensing

Safety / Storage and transport

4Assembly and installation

IMPORTANT

•The DMT is fully resistant to normal environments control

rooms.

•The DMT must not be placed where it can come into

contact with rain or direct sunlight!

Use a protective housing or weatherproof cover if in use

out of doors.

4.1 Assembly (mechanical)

The DMT can be wall, pipe or panel mounted (not for PROFIBUS®-DMT).

4.1.1 Wall mounting

Mounting materials (included in delivery):

1 x wall/pipe bracket

2 x 5x45 mm round headed screws

2 x 5.3 washers

2 x wall plugs Ø 8 mm, plastic

1 x rubber insert

1 x locking screw (PT)

Wall mounting, please follow the steps below:

왘Remove wall/pipe bracket from DMT:

pull the two snap fasteners outwards and push upwards (fig. 1, ➀).

Swing the wall/pipe bracket away from the DMT and pull downwards

(fig. 1, ➁).

왘Mark two drill holes diagonally opposite one another using the mounting

bracket as a template.

왘Drill the holes: Ø 8 mm, depth = 50 mm.

왘Screw the wall/pipe bracket in place inserting the washers (fig. 2).

왘If the DMT is also to be secured with a screw, pierce the screw hole in the

back of the housing (housing must be open) and attach a rubber insert

(fig. 2, ➀) to the bracket.

왘Hang the DMT onto the top of the bracket (fig. 3, ➀) and push down

gently against the bracket (fig. 3, ➁), then push upwards until you hear

aclick (fig. 3, ➂).

왘Tighten the locking screw to secure more firmly (housing is open).
