12 Functional Description
Only unscrew the housing cover if Type 663-Window is disconnected from the
mains or if the atmosphere is non-explosive. Otherwise, there is an explosion
hazard from sparking when operating ATEX-certified Type 663-Window in po-
tentially explosive atmospheres!!
Type 663-Window has two limit values, LIM1 and LIM2, with their respective lag times, which
can all be adjusted separately. If the value of the acceleration is below or above an adjustable
window-range, an alarm is generated. The lower limit of the window-range will be adjusted with
LIM1 and the upper limit with LIM2
In addition, Type 663-Window has an analogue current output. This delivers a direct current of
4...20 mA proportional to the vibration acceleration.

12.3 Self test
The self-test is to verify the correct functioning of the vibration control. Therefore, a test signal is
applied to pin 4 of the control. The test signal simulates a vibration amplitude exceeding the
maximum limit value. This will trigger the control's alarm condition.
Test signal:
a. Direct current, 24 V DC or
b. Square wave signal, 24 V DC / 0.5 Hz
Initial state:
Normal operation
Self-test start:
•Apply the test signal to pin 4.
•The output current signal increases up to ~23 mA.
•After < 35 s, the alarm relays drop out.
If one or both alarm relays fail to drop out, this indicates a fault.
•Remove the test signal.
•After a further < 60 s the output current signal has re-
turned to to 4 mA or its actual value
End self test
Final state:
Normal operation
Duration:
approx. 95 s
Test signal a is only available for production no. 75478 or later.
13 Assembly and disassembly
13.1 General notes
Assembly and disassembly work on and with the monitoring unit may only be performed by an
authorised specialist familiar with the safety regulations governing handling electrical compo-
nents! When using EX-certified monitoring units in potentially explosive atmospheres, the pro-
fessional must also be familiar with the relevant safety regulations!
Before assembly and disassembly disconnect the monitoring unit from the power sup-
ply! Separate plug connections must always be de-energized! If EX-certified monitoring
is operated in a potentially explosive atmosphere, there is otherwise an explosion haz-
ard, due to spark formation!
The monitoring unit housing must be earthed via the fastening - through the
machine earth of the mounting surface or through a separate protective conductor (PE)!

HAUBER-Elektronik GmbH

the side above the housing joint.
If any tampering is attempted, the seal label is destroyed and the tampering will be visible to the
system operator
Fig. 12: Seal label
14 Installation and Commissioning
Only authorised experts, who are familiar with the safety instructions for handling electrical com-
ponents are allowed to install or commission this control. For handling ATEX-certified controls
within potentially explosive atmospheres the expert also has to be familiar with the safety in-
structions relevant there.
Ensure the housing cover is properly fastened prior to commissioning (tighten-
ing torque = 5 Nm)! Otherwise, there is an explosion hazard from sparking
when operating ATEX certified Type 663-Window in potentially explosive at-
mospheres!
Prior to commissioning Type 663-Window, protect the mains with a microfuse
(medium time lag, 160 mA, breaking capacity C)!
Protect the connection cable and possible extension cables from electrical in-
fluences or mechanical damage! Ensure to stricly follow local regulations and
directives!
Check the self-test during commissioning.
15 Grounding Concepts to Avoid Ground Loops
Ground loops are among the most frequent problems in measurement setups with sensitive
sensor technology. They arise through unwanted potential differences inside the current circuit
between sensor and evaluation unit. As a countermeasure we recommend our Standard
Grounding Concept or, depending on your application, our Alternative Grounding Concept.

HAUBER-Elektronik GmbH
17
15.1 Standard Grounding Concept
With the standard grounding concept, the sensor cable shield has no connection to the sensor
housing (dashed circle). The sensor housing has the same potential as the machine earth.
Fig. 13: Standard Grounding Concept
1 Machine earth
2 Evaluation unit (measuring instrument, SPS, …)
3 Cable shield
4 Evaluation unit earth potential
5 Optional flexible metal tubing (only available for version with integrated cable)
15.2 Alternative grounding concept
With the alternative earthing concept, the sensor cable shield has a connection to the sensor
housing. The sensor housing uncoupled from the machine earth by means of an EMC adapter
(red). With the alternative earthing concept an electrically secure earth connection is only en-
sured for versions with an M12 connector. For variants with an integrated cable, the alternative
earthing concept cannot be used.
Fig. 14: Alternative grounding concept

3 Cable shield
4 Evaluation unit earth potential
5 EMC adapter (Hauber item no. 10473)
In your request, please notify us if you would like to use the alternative earthing
concept. We will then provide you with the appropriate sensor cable and the
EMC adapter.

16.1 General notes
Repair and cleaning work on vibration monitoring units may only be performed
by an authorised specialist familiar with the safety regulations governing han-
dling electrical components.
Before repair and cleaning disconnect the monitoring unit from the power sup-
ply! Separate plug connections must always be de-energized!
Immediately replace defective connection cables!
A defective vibration monitoring unit must be completely replaced!
