the pump and line freeze. When the valve opens, the drop in pressure triggers the pump
operation. The valve opening interval can be selected using the AI parameter

PRESSURE
(%)
Sets the minimum pressure value (as a % of SETPOINT1) to avoid false dry run
protections.
It may temporary occurs that pressure falls below SETPOINT1. This situation will be
tolerate in % as per the PI value.
STARTING UP
-
Before running, this Manual must have been carefully read and the instructions followed;
wrong settings and operations are thus prevented that could cause operating faults
-
Before starting the system, the pumps must be primed (filling and air bleeding)
-
After performing the operations described in the INSTALLATION chapter, the inverter can be
started.
-
When DGFIT is switched on, it enters the STARTING phase, which lasts 10 seconds, after
which
DGFIT returns to the same operating conditions in which it was when it was last
switched off
:
o
in WORK mode if at the time of the last shutdown was IN SERVICE
o
in OUT OF SERVICE mode if at the time of the last shutdown was OUT OF
SERVICE (OFF)
-
In case of accidental fall of the power line, if it DGFIT was in serivce, when the power returns,
it automatically returns in service
- To put IN SERVICE / OUT OF SERVICE DGFIT,
beat the START / STOP button.
- In applications with parallel inverters (MASTER / SLAVE) is just the MASTER inverter that
receives input from the keyboard
- SLAVE inverters operate independently only if the MASTER is turned off, in which case they
receive input from its own keyboard.
- In each group can be only one MASTER, one SLAVE 1 and one SLAVE 2.
- In normal operation, you can view the status parameters.
