2.7 Electrical data
nEXT pumps can be driven either by your own system or by the Edwards TIC Turbo Instrument Controller or TIC Turbo
Controller.
If you wish to use your own system, the size of the power supply required depends on your application. The power
limit setting determines how quickly you can ramp up the pump and dictates the size of power supply you will need.
If you have serial communications capability, or have access to an Edwards TIC, you can select the power limit setting
of the nEXT pump. Refer to
Table 11 for the maximum power limit settings for nEXT pumps. If your application
requires rapid cycling of the pump, you can achieve faster ramp times if you use a power supply that delivers higher
current, up to a maximum in accordance with
Table 11
If you do not have the facility to adjust the power limit setting, you must use a power supply capable of delivering
enough current to meet the Edwards factory default power limit setting, shown in
Table 11 .
If you intend to drive the nEXT pump using an Edwards TIC, be aware that there are several variants. Contact Edwards
to determine which is most suitable for your application.
2.8 Logic interface connector
nEXT pumps have a 15-way logic interface connector on the end of the logic interface cable. The logic interface
connector can be plugged directly into the Edwards TIC Turbo Instrument Controller or TIC Turbo Controller. You
must use a suitable connector mating half (not supplied) to connect the nEXT pump to your own equipment. Refer
to
Table 11 for the connector mating half type, to Table 12 for Logic Interface connector pins for the electrical
connections and to Figure 7 for the connector interface circuit diagrams.
