Exchange of electronics

Replacement set

Oscillator -

Capacitive electrodes

With this adapter set it is possible to

adapt the new oscillators E14, E15, E17

and E18 to capacitive electrodes with

terminal insert.

The replacement set must not be used

for electrodes certified acc. to CENELEC,

PTB Zone 0, WHG or VbF.

On electrodes for adhesive products

type 23.2… and 25.2… the replacement

set is also not possible.

The following parts are attached to the

replacement set for the oscillator of the

capacitive electrode:

- housing cover

- seal ring (in the housing cover)

- adapter plate

- connection cable

- oscillator (if ordered)

The following parts can no more be used:

- housing cover - old

- oscillator - old

Exchange of the oscillator

Proceed as follows:

• Separate the electrode from mains

voltage

• Remove the plastic cover from the

capacitive electrode

• Pull out the old oscillator

• Pull the probably available white

protective cover (5) out of the housing

(4)

• Loop the cable acc. to the figure

• Insert the probably available white

protective cover (5)

• Plug the new oscillator (2) to the

adapter plate (6). Probably the two

parts are also pre-assembled.

• Connect the two cables to the terminal

block of the oscillator (2) (1 = +; 2 = –).

• Make sure to which range the old

oscillator is adjusted. This can be

determined on the soldering bridge on

the lower side of the oscillator. Set the

changeover switch (7) to the same

range.

• Check the part between vessel and

thread of the electrode with an Ohm-

metre.When the resistance is œ, the

electrode must be earthed separately.

Hence use the thread on the hexagon

(3).

• Use the attached cover (1), to close the

electrode again. Note that the seal ring

fits correctly.

• Carry out the adjustment acc. to the

operating instruction of the signal

conditioning instrument.
