Introduction

The MKS Type T3P Throttle Valve is designed for use in downstream pressure control applications.

The T3P unit consists of a throttling isolation valve with an electronic housing attached to the motor plate, a

microprocessor, driver circuits which eliminate the need for a separate controller box, the RS-232 serial

communications interface, and analog outputs that reflect pressure or valve position. The valve is controlled

by using digital values sent through the serial network.

The operation of the controller is based on a digital pressure/position control algorithm that directs the valve

to the proper position for either pressure or position control. The pressure or position setpoint is sent as a

digital serial command. The T3P unit reads the pressure signal used for control applications directly from an

MKS Baratron pressure transducer. All of the unit’s operational settings are controlled using the serial

communication protocol.

When the T3P controller is turned off or experiences an unexpected power loss, all calibration constants are

saved in non-volatile memory.

Protection from RF interference and noisy electrical environments is increased by the use of a metal case, by

internal design elements, and by the use of surge and ESD suppression networks and RFI filtering on all

inputs and outputs. The T3P unit meets the testing standards required for the European CE Mark when used

with an overall metal braided shielded cable, properly grounded at both ends.

Generic Shielded Cable Description

MKS offers a full line of cables for all MKS equipment. Should you choose to manufacture your own cables,

follow the guidelines listed below:

1. The cable must have an overall metal braided shield, covering all wires. Neither aluminum foil nor spiral

shielding will be as effective; using either may nullify regulatory compliance.

2. The connectors must have a metal case with direct contact to the cable shield on the whole circumference

of the cable. The inductance of a flying lead or wire from the shield to the connector will seriously

degrade the shield’s effectiveness. Ground the shield to the connector before its internal wires exit.

3. With very few exceptions, the connector(s) must make good contact to the controller’s case (ground).

“Good contact” is about 0.01 ohms and the ground should surround all wires. Contact to ground at just

one point may not suffice.

4. For shielded cables with flying leads at one or both ends. It is important to ground the shield at each such

end before the wires exit. Make this ground with absolute minimum length. Refer to Figures 1 and 2.

(A ¼-inch piece of #22 wire may be undesirably long since it has approximately 5 nH of inductance,

equivalent to 31 ohms at 1000 MHz). After picking up the braid ground, keep wires and braid flat against

the case. With very few exceptions, grounded metal covers are not required over terminal strips. If one is

required, it will be stated in the Declaration of Conformity.

5. In selecting the appropriate type and wire size for cables, consider:

A. Voltage ratings.

B. Cumulative I

2

R heating of all the conductors (keep them safely cool).

C. IR drop of the conductors, so that adequate power or signal voltage gets to the controller.

D. Capacitance and inductance of cables that handle fast signals (such as data lines or stepper motor

drive cables).

E. Some cables may need internal shielding from specific wires to others.
