specific settings for each application.
Switch # 3 – Main / Generator control
When starting from a diesel – generator supply,
starting process can sometimes terminate due to
instability of the supply system. To operate generator
mode set Dip Switch # 3 to On and special starting
characteristics, suitable for Diesel Generator supply –
with unstable voltage & frequency become operative.
Closure of Dual Adjustment contact (terminal 8)
operates the special starting characteristics.
When operating from network voltage and alternatively
from diesel generator, set normal starting
characteristics for Main and suitable parameters for the
Diesel Generator (for example, faster acceleration,
lower current limiting, etc.) on Dual Adjustment
setting.
WARNING
When operating in Generator Mode, or with curve
“0” motor must be loaded, otherwise, vibration may
occur during starting and stopping.
