Commissioning
DANGER - HIGH VOLTAGE
When commissioning the unit, please observe all safety rules that apply to the handling of live equip-
ment. Ensure that you know how to provide first aid in the event of an uncontrolled release of energy
and that you know where the first aid kit and the nearest telephone are. Never touch any live compo-
nents of the system or on the back of the system:

CAUTION
Only a qualified technician may commission unit. The "EMERGENCY-STOP" function must be opera-
tional prior to commissioning of the system, and must not depend on the unit for its operation.
CAUTION
Prior to commissioning, ensure that all measuring devices are connected in correct phase sequence.
The connect command for the unit circuit breaker must be disconnected at the unit circuit breaker. The
field rotation must be monitored for proper rotation. Any absence of or incorrect connection of voltage
measuring devices or other signals may lead to malfunctions and damage the unit, the engine, and/or
components connected to the unit!
CAUTION
Please consider that the unit does not have an internal rotating field monitoring.
The unit assumes always a clockwise phase rotation direction of all voltage systems, which are meas-
ured.
A rotating field monitoring must be provided by the customer in order to avoid a CB closure with a
counter-clockwise rotating field.
Procedure
1.
Disconnect the breaker closing circuit directly at the power circuit breakers.
2.
After wiring the unit and ensuring all voltage-measuring devices are phased correctly, apply the control
system voltage (24 Vdc). The "automatic" LED will illuminate.
3.
By simultaneously pressing the two pushbuttons "Digit
" and "Cursor
", the configuration mode is ac-
cessed. Prior to entering the configuration mode, ensure that the "configuration locked" discrete input is
de-energized. After entering the access code number, the unit may be configured according to the applica-
tion requirements (see the chapter regarding the parameters). The "automatic" LED will be extinguished.
4.
Configure the control unit. The setting limits can be read either from the description of the screen or from
the list of parameters at the end of the operating manual.
5.
After configuring the measuring variables, the unit will display the measured values. These values should
be confirmed with a calibrated measuring instrument prior to enabling any breaker or control functions.
If
a measuring voltage has been wired incorrect or not at all, this may lead to an asynchronous break-
er closure in an active
dead bus
start!
