► Apply the
Decommissioning
procedure.
Restarting after emergency stop (using the equipment)
The emergency stop is managed by the equipment in which the pump is integrated. To restart the pump
after an emergency stop, you must:
1. Correct the problem,
2. Unlock the emergency button on the equipment/tool: the pump restarts automatically.
Restarting after power failure
► After a power failure, the pump restarts automatically when the power is restored.
DANGER
Risk of injury when power is restored to the pump
In remote control mode, contact S1 (terminals 7 and 8 on the remote control connector) switches the
pump on/off. The S1 contact wiring is the customer’s responsibility.
► Provide adequate wiring that can authorize or prevent auto-restart.
► Take all the measures required to prevent risks resulting from this type of operation.
6.3.3 Operation in RS-485 link mode
► Wire and connect the serial link pins to the remote control connector.
Starting the pump
1. Position the main switch to
I
position: the pump is powered.
2. Send an
‘ACPON’
order via the serial link:
● The pump starts and
runs at the speed set on the serial link parameters
.
●
G version
: operates the purge.
●
CV version
: operates the purge and gas ballast.
Note: when ACPON is activated, if the S1 dry contact is closed then opened on the remote control con-
nector, then the pump stops.
Influence of rotation speed on pump performances
Pump performances are guaranteed for a nominal speed of
80 Hz
. Changing the
rotation speed affects the pumping speed and the ultimate pressure of the pump. At
low speed, it is the customer’s responsibility to find the correct settings according to
the pump and the process.
● Do not exceed the maximum frequency
● Do not run the pump continuously at speeds
≤ 60 Hz
.
Shutting down the pump
1. Isolate the pump in the pumping line (isolation valve at pump inlet, closed) and let it run for 1 hour
with gas ballast or purge open.
2. Send an
‘ACPOFF’
order via the serial link: the pump stops.
Restarting after emergency stop (using the equipment)
The emergency stop is managed by the equipment in which the pump is integrated. To restart the pump
after an emergency stop, you must:
1. Correct the problem.
2. Unlock the equipment’s emergency stop button.
3. Send an
‘ACPON’
order via the serial link.
Powering off
► Set the switch to the
O
position.
Prolonged stoppage
► Apply the
Decommissioning
procedure.
6.4 Operation monitoring
The pumps equipped with a three-phase frequency converter have two LEDs at the rear that indicate
the pump’s operating status.
