Introduction
The Terranova® 760 series Ion Pump Power Supply is designed to start and operate a wide range
of ion pump models from a number of manufacturers. The Terranova® 762 is factory-configured
to operate two ion pumps. The factory changeable polarity provides the ability to operate pumps
that require either posive or negave high voltage. With programmable parameters and a
number of ways to exchange informaon, the Terranova® 760 series' versality allows its use in a
number of applicaons.
Legacy Terranova®741/751/752/751A/752A
The legacy Terranova® 741, 751/752, and 751A/752A models have been (or will be soon in the
case of the 751A/752A) disconnued and replaced by the Terranova® 760 series. Although the
Terranova® 741, 751/752, and 751A/752A have been disconnued, the units may sll be sent
to Duniway Stockroom for service. Please contact your Duniway Stockroom customer service
representave for further details.
Bodily harm or equipment damage can result due to electric shock
originang from the input AC voltage, internal unit potenals, or
high voltage output. The high voltage output hazard can exist either
from direct contact with the high voltage lead or due to loss or lack of
proper grounding from either the Terranova® 761 or ion pump.

Installation
Installing the Terranova® 762 Controller
The Terranova® 762 Controller is housed in a standard EIA half-rack box. See Figure 1for
dimensions. The control unit may be used as a table-top device or can be installed in most
equipment racks and cabinets. User should leave enough clearance at me of installaon to both
access rear cable connecons and for venlaon purposes.
Connecting the Ion Pump(s)
The Terranova® 762 controller is equipped with either two 10 kV Kings or two Fischer-style high
voltage connectors. The connectors are located on the back of the unit labeled VOLTAGE OUTPUT
(see Figure 2). To connect and operate the ion pumps with the Terranova® 762 controller the
user will require a Duniway or equivalent ion pump cable.
To properly connect the Terranova® 762 controller to the ion pump(s):
1. Secure the ion pump cable to the respecve ion pump high voltage feedthrough
2. Secure the ion pump cable to the respecve VOLTAGE OUTPUT connector
3. Secure the required secondary ground sense lead to the ion pump body and
respecve GROUND SENSE #6-32 stud and Keps nut assembly (see Safety Interlock)
The user should always ensure the ion pump and high voltage cable are both properly connected
and secured before use.
Use of ion pump cables other than those approved by Duniway
Stockroom may lead to operaonal problems or safety hazards.
WARNING! CAUTION
NEVER apply power to the Terranova® 762 unl
proper grounding has been established.

Safety Interlock
A safety interlock or secondary ground sense circuit is incorporated into the Terranova® 762
controller to disable high voltage operaon when open. The safety interlock circuit is completed
via external leads available on most Duniway ion pump cables. The external leads must properly
connect the ion pump body to the respecve GROUND SENSE stud (see Figure 2) to complete
the safety interlock circuit and enable high voltage operaon. High voltage output will be disabled
if an open circuit or ground fault is detected. To restart high voltage operaon, user must correct
the grounding issue. Table 1lists various ground sense connecon condions and respecve
effects on high voltage operaon.
A redundant ground connecon, either intenonal or unintenonal, between the control unit
and ion pump may circumvent the safety interlock feature. User should correct any grounding
issues to ensure safe operaon. A potenal (unintenonal) redundant ground may occur through
chassis contact with the ion pump or vacuum system ground when both the ion pump and
Terranova® 762 are mounted on the same conducng rack or cart.

Power-up Display
The Terranova® 760 series will output the Power-up screen as shown in Figure 3 when turned ON
via the POWER buon and both self-adjusng cooling fans will automacally start. If the power-
loss restart funcon is disabled, the control unit will output the Main display as shown in Figure 4
and the channel will enter standby mode.

The Main Display is the starng point for using the Terranova® 760 series. The Main Display screen
provides access to all configuraon menus as well as ion pump operaon. The Main Display
outputs a number of configuraon sengs via the Status Bar located atop the screen (See Figure
4).
The middle secon of the screen is reserved for channel-specific informaon. As seen in Figure 4,
the channel number and polarity appear on the le-hand side of the screen. The right-hand side
of the screen is reserved for channel output. "Ready" will appear when a channel is in standby
and "ready" for use. Otherwise, the pressure, current, and (high) voltage values will be output
(see Figure 5) during normal ion pump operaon or immediately aer a power-loss restart.
Buons are located at the boom of the screen to either operate the ion pump or configure the
Terranova® 760 series. The HV ON/OFF buons will toggle in funcon depending on the state of
the high voltage.

The parameter entry screen allows the user to enter a new parameter value via the front panel.
To open the respecve parameter entry screen, the user must tap the numerical value of the
parameter to be modified. Only parameters that are enclosed by an orange rectangle (see Figure
10) will open a parameter entry screen. The Terranova® 760 series will return to the Main Display
if leunaended for more than 5 minutes; any unsaved changes will be deleted. Any unsaved
changes before a power loss will also be deleted.
Figure 11 illustrates an example of a parameter entry screen — all parameter entry screens will
have a similar layout. A number pad with mathemacal symbols will become available so the user
can input the new parameter value. The currently-stored value is visible in the top, lecorner of
the screen. The Low and High Limit values define the range of the parameter. The new value will
appear on the yellow rectangle and may be input in a number of formats so long as it possesses
the correct syntax and is within the parameter range. An incorrect format or out-of-range value
will output the error code "Value out of bounds" below the yellow rectangle (see "Parameter
Entry Screen Example").
Buon funcons are as follows:
Tap to temporarily store value and return to the Channel Configuraon display.
Tap to clear all input characters.
Tap to backspace one character at a me.
Tap to return to the Channel Configuraon display without saving any changes.
