following characteristics:
Suitable to control leakage current and, in case of
short pulsed leakage current.
Must operate in case of a fault alternating current,
and in case of fault current with DC content, such
as fault pulse DC current and at DC current
The electric control box must have installed a
B-type differential switch or GFCI.
These protections must be signed with the
followings symbol.
7. STARTUP AND OPERATION
7.1. Commissionig
It is strongly advised that commissions of
the set must be done using an approved
agent or one of our Engineers.
Correct commissioning will guarantee the longevity
of the set and ensure that is operates at optimum
efciency.
water supply and all electrical connections made.
Most of the basic functions are pre-programmed at
the time of production but the most basic settings
must be checked. If modications on the settings
are required refer to the Easymat or I-Mat manual
in this pack
7.2. Vessel pressure
OFF
Before installation, check the status of the air
cushion load in the vessel.
Air preloaded pressure of the vessel must be of 0,2
bar lower than the restart pressure value.
7.3. First starting
OFF
After completing hydraulic and electrical connection
and checked the preloaded pressure (for booster
set with membrane tank), start the plant as
indicated below:
Prime the pumps (see the pumps’ instructions).
Pump with suction lift:
- Fill the suction pipe and the pump body by means
of the plug hole located close to the delivery port
of the pump.
- Fill the suction tube by pouring water through the
plug hole on the suction manifold of the pump.
Pump with positive suction head:
- Open the gate-valve in the suction pipeline.
With sufcient head, the water will overcome the
resistance of the non-return valve tted in the
suction side of the pump and will ll the pump
body. Otherwise, prime the pump with the plug
hole near the delivery port.
Never run the pump for more than ve
minutes with a closed gate valve
Starting pumps
Press the button
(play) in all the frequency
converter, to change the pump status from STOP to
run. The pump starts up with the acceleration ramp
set to reach the wished set-point.
When the motor start turning, check the
direction of rotation.
If the booster set has been primed correctly, after
a few seconds the pressure will begin to increase
on the display.
If, after a few seconds of operation the pressure
remains at 0.0 bar, stop the booster set by selecting
(stop) in each frequency converter as priming
has not been carried out correctly and the pump is
idling. Re-prime the pumps and repeat the starting
up procedure.
7.4. Inversion of the direction of rotation
OFF
To change the direction of rotation of the motor push
the button
(menu) and then with the button
(plus) or
(minus) move up to the programming
parameter UP. Conrm with
(enter) and with
the button
(plus) or (minus) move up to
the parameter UP04, conrm with (enter) and by
pushing of the button
(plus) change the value,
conrm with
(enter). To exit the program, push
(menu) until you arrive on the basic display,
when you are out from the setup mode the icon
disappear.
7.5. Quick set-point modication
ON
It is possible to change the set point pressure
without enter on the user parameter (UP menu).
Pushing the button
(enter) for more than 5
seconds, in any of the frequency converter, you
will enter directly to the set point pressure (UP05
parameter).
By pushing of the buttons
(plus) or (minus)
change the pressure value and conrm with
(enter).
By pushing of the button (menu)
the system
will return to the basic display (see paragraph 9.1.).
