Starting the pump
An hour counter displays the pump model and running time in hours.
1. Position the main switch to
I
position: pump starts
automatically
.
●
G version
: operates the purge.
●
CV version
: operates the purge and gas ballast.
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. Position the main switch to
O
position, and/or activate the mains circuit breaker: pump stops.
Prolonged stoppage
If the pump is subject to a prolonged stop:
► 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 following a 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 local mode, permanent contact between terminals 7 and 8 (cover plug strap) triggers an auto-re-
start when the mains power supply is restored to the pump.
► Take all the measures required to prevent risks resulting from this type of operation.
6.3.2 Remote control mode operation
► Wire and connect the remote control connector located at the rear of the pump
Starting the pump
1. Position the main switch to
I
position: the pump is powered.
2. Send a
‘Start’
pump order via the S1 contact:
● The pump starts up and
runs at the speed set on the contacts of the remote connector
.
●
G version
: operates the purge.
●
CV version
: operates the purge and gas ballast.
Note: when the S1 contact is closed, sending the
'ACPON'
or
'ACPOFF'
command via the serial link
doesn’t disturb the operation (‘context error’ response on serial link).
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 a
‘Stop’
pump order via S1 contact: the pump stops.
Powering off
► Set the switch to the
O
position.
Prolonged stoppage
If the pump is subject to a prolonged stop:
