Warranty
Duniway Stockroom Corporaon (“DSC”) warrants all Terranova® products to be free of defects in
material and workmanship for a period of one year from the date of shipment. At our opon, we
will repair or replace products which prove to be defecve during the warranty period. Liability
under this warranty is limited to repair or replacement of the defecve item(s). Shipping damage
is excluded from the scope of this warranty. Pressure gauges of all types are excluded from this
warranty.
Terranova® products are warranted not to fail to execute programming instrucons due to
defects in materials and workmanship. If DSC receives noce of such defects during the warranty
period, DSC will repair or replace rmware that does not execute its programming instrucon
due to such defects. DSC does not warrant that the operaon of the rmware or hardware will
be uninterrupted or error-free.
If this product is returned to DSC for warranty service, the Buyer will prepay shipping charges and
pay all dues and taxes for products returned to DSC. DSC will pay for the return of products to
the Buyer, except for products returned to the Buyer from a country other than the United States.
Please contact your Duniway Stockroom customer service representave for a Return Merchandise
Authorizaon (RMA) number if you need to return a Terranova® product.
Limitation of Warranty
The foregoing warranty does not apply to the defects resulng from:
1. Improper or inadequate maintenance by the Buyer,
2. Buyer-supplied interfacing,
3. Unauthorized modicaon or misuse,
4. Operaon outside of the environmental specicaons of the product, or
5. Improper site preparaon and maintenance.

Introduction
The Terranova® 752A Dual Ion Pump Power Supply is designed to start and operate a wide range
of ion pump models from a number of manufacturers. The Terranova® 752A is congured to
simultaneously-operate two ion pumps. Moreover, the user-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® 752A's versality
allows its use in a number of applicaons.
Legacy Terranova®752
The legacy Terranova® 752 model has been disconnued and replaced by the Terranova® 752A.
Although the Terranova® 752 has been disconnued, the unit 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 ion pump or Terranova® 752A.

Pre-installation Settings
Mode of Operation
The Terranova® 752A has three dierent modes of operaon available: Mode 0, Mode 1, and
Mode 2. The selected mode of operaon applies to both channels. In all three modes, high
voltage operaon may be manually controlled via the HIGH VOLTAGE ON/OFF buon or through
serial communicaon.
Mode 0: Standard Operation
High voltage operaon and parameter input is conducted via the front panel or through serial
communicaon. High voltage output is dependent on the safety interlock circuit (see "Safety
Interlock" on page 20) of the channel. High voltage operaon will be interrupted if the
respecve safety interlock circuit is open or a ground fault is detected. Default mode of operaon.
Mode 1: Secondary Interlock
High voltage operaon and parameter input is conducted via the front panel or through serial
communicaon. However, high voltage output is dependent on a secondary interlock in addion
to the safety interlock circuit (see "Safety Interlock" on page 20) of the channel. The secondary
interlock is based on the voltage level of a +5 V TTL circuit. A user-installed switch can also be used
to operate the secondary interlock.
To commence and maintain high voltage output, the respecve safety interlock circuit must
remain closed and a LOW-level TTL signal must be connuously applied (or the installed switch
must remain closed). High voltage operaon will be interrupted if the respecve safety interlock
circuit is open, a ground fault is detected, or when a HIGH-level TTL signal is applied (or the
installed switch is opened) to the respecve channel. The TTL signal is input (or switch is installed)
between PIN 8 / PIN 3 of the MISCELLANEOUS port (PIN 13 / PIN 15 on the AUXILIARY port) for
CHANNEL 1 and PIN 10 / PIN 15 of the AUXILIARY port for CHANNEL 2. See Table 1 on page 6
and Table 2 on page 7 for pin conguraon.
If user aempts to start high voltage operaon with
the second interlock circuit open, error code ER6
will be output onto the respecve CURRENT display.

Mode 2: Remote Operation
High voltage operaon may be controlled directly via the front panel or remotely through either
serial communicaon or the voltage level of a +5 V TTL circuit. A user-installed switch can also be
used to control high voltage operaon. High voltage output is dependent on the respecve safety
interlock circuit (see "Safety Interlock" on page 20). High voltage operaon will be interrupted
if the respecve safety interlock circuit is open or a ground fault is detected. All unit parameters
must be set or changed via serial communicaon (see "Mode 2 Special Setup").
If using a TTL circuit (or switch), high voltage output will commence at a rising edge aer a LOW-
level TTL signal (or switch closure) is applied for more than 2 seconds. High voltage output will
be interrupted at a falling edge immediately aer a LOW-level TTL signal (or switch closure) is
applied. The TTL signal (or switch) is input between PIN 8 / PIN 3 of the MISCELLANEOUS port (or
PIN 13 / PIN 15 on the AUXILIARY port) for CHANNEL 1 and PIN 10 / PIN 15 of the AUXILIARY port
for CHANNEL 2. See Table 1 on page 6 and Table 2 on page 7 for pin conguraon.
Mode 2 Special Setup
In Mode 2, user may only scroll through unit parameters via the respecve SELECT buon. To set
or change parameters via the front panel, the Terranova® 752A must enter a special setup mode.
If user aempts to change parameters via the front panel, error code ER4 will be output on the
respecve CURRENT display.
To access the special setup mode:
1. Turn the control unit OFF via the POWER buon
2. Depress the CHANNEL 1 SELECT buon, and
3. Restart the control unit via the POWER switch
If successful, CHANNEL 1 HIGH VOLTAGE display will ash the code SU. Thereaer, user may
release the CHANNEL 1 SELECT buon and modify parameters via the front panel buons. To
return the Terranova® 752A to normal Mode 2 operaon, user must restart the control unit via
the POWER buon.
