9. Operation and maintenace

Display contrast

With instruments in wall-mounting enclosures the display contrast can be adjusted to
the actual light conditions by means of a potentiometer. It is indicated in the connection
diagram with the word „display“.

Cleaning

The front and the display should not get in touch with organic solutions such as
methanol. Never let water get inside the instrument. We suggest to simply use a damp
cloth for cleaning.

Exchange fuse

WARNING!

Disconnect the power supply before opening the instrument!

ATTENTION

Mind that the cable connections to the front are not damaged, broken
or torn during the process!

Instruments in wall-mounting enclosures have an internal fuse which has to be
replaced at need. You will find a spare fuse fixed to the inside of the terminal cover.
Information on the fuse can be found in the chapter „Technical data“.

To exchange the fuse, open the front carefully. The fuse is located in the lower right
hand side. It is kept in place by a Bayonet lock. Turn the lock to the left until the fuse
pops up. Exchange it and fix the new fuse by turning the lock to the right. Put the front
back on and fix it tightly.

Maintenance of the safety functions

Regularly check the alarm relay to make sure that in case of failure both the indication
by the instrument and the recognition by the superior control (SPS etc.) work reliably.

You can set off the alarm for example by setting limit S1 to a value smaller than the
current measured value.

NOTE

Mind that perhaps an alarm delay has been set. Also remember to
restore the original settings after the test!

Regularly check the function of the water level or flow sensor to make sure that in case
of lack of water the sensor gives the signal that leads to the controller stop.

Simulate lack of water by briefly interrrupting the water supply. This must lead to a
switch of the level sensor or a decrease of the flow signal, and the message „ext.
controller stop“ or „no water“ must appear in the display.
