This manual is intended for operating and service personnel.
Please read the manual carefully so that you fully understand the UniSAB III control system and know
how to operate it correctly. Damage occurring as a result of incorrect operation is not covered by John-
son Controls Denmark's guarantee.
Note the
version number
of this manual. The version number is printed on the preceding page. It is im-
portant that this number is identical to the UniSAB III version number, which is shown in the picture
Serv-
ice/Diagnosis/Software/Software version
.
Never
use a manual with a lower version number than your
UniSAB III software.
Warning!
If it is necessary to service the UniSAB III control system, the power supply to the compressor motor
must be switched off on the main switch to prevent the compressor from starting up accidentally. As the
UniSAB III box contains live parts, it is very important to comply with the safety regulations on site. Fail-
ure to do so may cause damage to equipment and affect personal safety. Even though the power supply
to UniSAB III is switched off, some of the terminals may still be live.
Only authorised personnel is allowed to service UniSAB III. If UniSAB III is connected to a network, al-
ways remember that the compressor can be started from REMOTE. This
cannot
be avoided solely by
changing settings on the UniSAB III display.
If it is discovered that the
Supervisor Password
has been used to set a value that is critical for safe
compressor operation (i.e. outside the specified limits, which can cause irregular or incorrect operation
or, in worst case, breakdown) it must be anticipated that Johnson Controls Denmark is considered enti-
tled to reduce its warranty obligations.
Johnson Controls Denmarkfurther accepts no liability of any kind for damage to the compressor unit and
plant parts caused by torsional oscillation, or the like, which is attributable to built-in VSD solutions initi-
ated by the customer after delivery.
Emergency stop
Activate the emergency stop by a light touch and deactivate it by turning it clockwise. The emergency
stop breaks the power circuit of the compressor motor starter/motor guard. Activation of the emergency
stop during operation will lead to immediate unloading of the motor guard, while there will still be power
on UniSAB III. Therefore, it is always possible to read the compressor state.
