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!
Procedure
1.
After wiring the unit and ensuring all voltage-measuring devices are phased correctly, apply the control
system voltage (i.e. 24 Vdc). The "Operation" LED will illuminate.
2.
By simultaneously pressing the two push buttons "Digit

", the configuration mode is ac-
cessed. After entering the access code number, the unit may be configured according to the application
requirements (see the chapter regarding the parameters).
3.
After applying the measured variables, the unit will display the measured values. These values should be
confirmed with a calibrated measuring instrument.
