3.6 Electrical data
The pumps can be operated by the customers system or by the manufacturer's TIC Turbo
Instrument Controller or TIC Turbo Controller.
If using the customer system, the size of the power supply depends on the applicaon.
The rate of increase in the pump speed is dependent on the power limit seng. The
power limit seng overrides the necessary power supply seng. If the serial
communicaons or an access to the manufacturer's TIC is available, the power limit
seng of the pump can be selected. Refer to Table: Logic interface technical data for
the maximum power limit sengs for the pumps. If the rapid cycling of the pump is
necessary for an applicaon, you can get the faster rate of increase in the pump speed if
the power supply supplies higher current, up to a maximum in accordance with Table:
Logic interface technical data.
If the power limit seng is not adjustable, use a power supply capable to supply
sucient current to meet manufacturer's factory default power limit seng shown in
Table: Power limit seng.
The manufacturer's TIC has variants. If the pump is operated using the
manufacturer's TIC, contact us to select the applicable variant for the applicaon.
3.7 Pumping media
WARNING: DANGEROUS GASES
Risk of asphyxiaon. R
elease the dangerous gases and gas mixtures safely. Do not
expose people to the gases. If hazardous gases or vapour must pump, obey the safety
recommendaons of the supplier of the gas or vapour.
WARNING: PYROPHORIC OR EXPLOSIVE GASES
Risk of explosion. Do not use the nEXT pump t
o pump pyrophoric or explosive gas
mixtures as the pump is not applicable for this purpose. The pump and its
connecons are not designed to contain an explosion.
