PEDROLLO DGF/T M/M 8.5 Manual De Uso Y Mantenimiento página 42

-
Before starting up, read this Manual thoroughly and follow the instructions to avoid any
wrong settings and operations that could cause operating faults.
- Do not start the pumps dry, not even for a few moments.
- The inverter can be switched on only after performing all the steps described in the
INSTALLATION chapter
- When DGFIT is powered by the mains, it enters a STARTING phase, followed by a prompt
to reset the parameters, in self-learning by WIZARD; these phases last about 10 seconds,
after which the inverter returns to the same operating conditions in which it was upon the
last shutdown:
o IN SERVICE if on the last shutdown it was IN SERVICE
o OUT OF SERVICE if on the last shutdown it was OUT OF SERVICE (OFF)
In the event of an accidental voltage drop, if DGFIT was IN SERVICE (ON), when network
is restored it returns automatically INTO SERVICE (ON).
- To PUT DGFIT INTO SERVICE / OUT OF SERVICE , press the START/STOP key.
- In applications with inverters in parallel (MASTER / SLAVE) only the MASTER inverter
receives the input from the keypad
- SLAVE inverters operate autonomously only if the MASTER is off; in this case they
receive inputs from their own keypad.
-
In each unit there can be only one MASTER, one SLAVE 1 and one SLAVE 2.
- In normal operation it is possible to view the status parameters.
