conditions. Gamma vacuum products are designed and manufactured to
provide protection against electrical and mechanical hazards for the
operator and the area surrounding the product.
2. Installation procedures are for use by qualied, authorized personnel
who have experience working with 50 V or greater. To avoid personal
injury, do not perform any installation or service unless qualied to do so.
3. There are no serviceable parts inside the controller power-supply, and
voltages as high as 7 kV may be present. Do not open the supply case
under any circumstances. In the event of the power‑supply requiring
attention, return it to Gamma Vacuum.
4. Do not disconnect the high-voltage cable with the power on. After turning
the power o, allow at least one minute before disconnecting electrical
equipment.
5. Do not operate the controller without a proper electrical ground or near
water. The controller may be damaged and its safety reduced if it is
operated outside of its specications.

2. General information
The DIGITEL MPCq is an ion pump power supply controller.
It is designed to operate up to two independent ion pumps along with a
Titanium Sublimation Pump (TSP).
It can accommodate any ion pump size up to 1200 L/s.
The front panel display provides direct readout of the ion pump voltage,
current, or pressure.
Individual model specication information is located on our website at:
www.gammavacuum.com.
WARNING:
Do not use unauthorized parts. Such parts may compromise safety. Contact
Gamma Vacuum with any questions.
WARNING:

missing, notify the carrier and Gamma Vacuum. Save all packaging material
for inspection.

4. Installation
The DIGITEL MPCq is a full 19-inch rack controller. No additional hardware
needed to install in a standard 19-inch wide device rack.
Maintain a 2.52 in. (64 mm) clearance behind controllers for cable bend
radius and proper airow.
CAUTION:
This equipment uses a detachable power supply cord. Do not replace with
inadequately rated supply cords.
4.1. Required items
You will need the following items to install the controller:
1. A 3-wire, detachable, universal input power cable (included).
2. A High Voltage (HV) cable for each pump (ordered separately).
3. A safety ground cable for each pump (ordered separately).
4.2. Installation procedure
1. Place the controller in its location and secure as necessary.
2. Connect the safety ground cable to the pump and the safety ground stud
at the DIGITEL rear panel.
3. Connect the high voltage cable to the ion pump and the high voltage
connector on the DIGITEL rear panel (J501 - J504).
4. If high voltage cable has an optional safeconn feature (HV interlock), an
additional connector is part of the high voltage cable. Connect it to the
safeconn connector (J401 - J404), otherwise, use safeconn shorting jumper
cable to connect to safeconn connector (J401 - J404). Safeconn interlock
must be satised, otherwise HV cannot be turned on.
5. Verify correct input voltage requirements. Connect mains AC power cable
to input power receptacle on the controller rear panel.

900034_C - Installation

5. Controller conguration
Following conguration options are specied at order time:
5.1. Input mains AC voltage (110 V a.c. vs. 220 V a.c.)
Controller does not have universal power input, thus input mains AC voltage
is part of the controller conguration.
Care must be taken when connecting controller to mains AC voltage to avoid
connecting controller to wrong input voltage.
5.2. Supply conguration
Following controller congurations are valid:
1. One HV supply or channel
2. Two HV supplies or channels
3. One HV supply or channel and one internal TSP supply
5.3. Output voltage polarity for each HV channel (positive vs negative)
In case of positive polarity, output voltage is set to 7 kV by default.
In case of negative polarity, output voltage is set to -5.6 kV by default.
Output voltage is xed (linear power supply, transformer tap).
5.4. Type of the HV output connectors
Following are standard HV connector types for J501 - J504:
1. SHV-10 kV (matching safeconn connector type is SMB style).
2. Fischer (matching safeconn connector type is mini banana style) other HV
connector types are available per request.
5.5. Number of HV output connectors per HV supply
There can be more than one HV output connector tied to the same HV
supply. In such case, connectors are tied in parallel.
Controller can have maximum of 4 HV output connectors in any
conguration. For example, 2 HV output connectors per 1 HV supply.
5.6. Communication interface
Controller comes standard with Serial and Ethernet interface.
Probus interface is optional.
5.7. Remote TSP control
Controller comes standard with connector J505 CTRL installed.
Connector can be used to connect and control remote TSP Controller.
See rear panel section for connector location.
If internal TSP supply is installed, connector J505 is not available.

6. HV control or ion pump operation
6.1. Prior to using an ion pump
Conrm following:
▪Rough pump down to 1 x 10-4 torr or less (the lower the better).
1 x 10-6 torr is recommended. See Rough Pump user manual for details.
NOTE:
Use the full extent of available rough pumping before starting an ion pump to
extend pump’s lifetime, improve system ultimate pressure, and get accurate
current readings.
▪Evacuate the Vacuum System.
▪Ensure contaminants do not exist in the system.
▪If necessary (i.e. ion pump exposed to atmospheric pressure) bake the ion
pump and system into roughing pump to achieve lowest pressure. See
ion Pump user manual for details.
6.2. Prior to turning on HV and starting an ion pump
Conrm following:
▪Verify high voltage cable is installed and connecting controller High
Voltage (HV) output connector (rear panel, J501 ‑ J504) to the ion pump.
▪Verify controller and connected ion pumps are grounded using
redundant ground wire.
▪Verify controller’s high voltage output has correct polarity for the
connected ion pump (positive for diode pump, negative for triode pump).
▪Verify safeconn interlock is satised. If high voltage cable has optional
safeconn interlock feature, an additional connector is part of the high
voltage cable. Connect it to controller’s safeconn connector (J401 - J404). If
high voltage cable does not have safeconn interlock feature, use safeconn
shorting jumper cable to connect to controller’s safeconn connector
(J401 ‑ J404).
▪Safeconn interlock must be satised, otherwise HV cannot be turned on.
▪If safeconn interlock is not satised, controller will display error 20
(safeconn interlock not satised) for that HV channel.
▪Verify proper pump size is congured. HV cannot be turned on if pump
size is set to 0. By default pump size is set to 0. If pump size is set to zero,
controller will display error 22 (pump size not congured) for that HV
channel.
6.3. Turn HV on and o
Turning HV on and o can be achieved:
▪Using front panel touchscreen.
▪Using remote communication (serial, ethernet or probus).
▪Using rear panel connector J104, Misc. I/O. (Digital Inputs).

7. Pressure measurement
Pressure value is determined using following equation
Where:
I - Current in amps.
V - Voltage in volts.
U - Pressure units conversion factor (1 for Torr, 1.33 for mbar and 133 for
Pascal).
F - Congured pump pressure factor. Typically set to 1. See Supply setup on
page 20.
S - Congured pump size in L/s. See Supply setup on page 20.
