Edwards nEXT nEXT85 - Ground the Connections; Connect the Logic Interface to the TIC or TAG; Connect the Logic Interface to the Control Equipment

You can operate the pump using the manufacturer's TIC Turbo Instrument Controller, TIC
Turbo Controller, TAG Controller or by the customer supply and controlled using the
customer system. Refer to Connect the logic interface to the control equipment on page
42 for informaon about control. Refer to Connect the electrical supply on page 43 for
instrucons on how to connect the electrical supply.
4.4.1 Ground the connecons
We recommend you to install a separate ground conductor to ground the pump.
Ground the pump using the given connecon. Refer to Figure: Dimensions - nEXT85
ISO63 on page 18, Figure: Dimensions - nEXT85 CF63 on page 19, Figure: Dimensions -
nEXT85 ISO100 on page 19 and Figure: Dimensions - nEXT85 DN40 on page 19.
Use the braided wire that is not insulated or a separate insulated green / yellow
connector, an M5 x 10 screw and shake proof washer supplied (installed to the ground
hole of the pump) to install the ground connector to the pump. The size and rang of
the ground conductor has to be suciently large to protect against other equipment in
the customer system. The impedance between the pump body and the ground
connecon point must be < 0.1 Ω.
4.4.2 Connect the logic interface to the TIC or TAG
If the manufacturer's TIC Turbo Instrument Controller, TIC Turbo Controller or TAG
Controller is used to power and control the pump, connect the pump logic interface
cable into the back of the TIC or TAG. Refer to the TIC or TAG Instrucon Manuals for
more informaon.
If the TIC or TAG is to be used to control the pump, make sure that the RS485 / RS232
slide switch is in the RS232 posion. Refer to Connect the serial interface to the customer
control equipment on page 45. If the switch is in the RS485 posion:
▪
the TIC will connect to the pump in a parallel mode (that shows the pump type as
nEXTp)
▪ the serial connecon is disabled
▪ start and stop is possible
▪
the TAG will not connect to the pump or control the pump.
4.4.3 Connect the logic interface to the control equipment
If you use your own control system to operate the pump, use an applicable connector
mang half (not supplied) to connect the control equipment to the connector on the
logic interface cable.
Refer to Table: Logic interface connector pins on page 26 for the details of the logic
interface connector pins, when you do the electrical connecons to the pump.
Refer to Table: Logic interface technical data on page 25.
