AUMA Matic Positioner

Calibration Instruction

AUMA MATIC Compacts consist of motor controls, local controls and other control elements, which may be
required to operate an electric actuator

AUMA Actuators, Inc. USA

Scope

These instructions are intended to cover the AUMA MATIC compact in both the C and S configuration with an
AUMA positioner board. These instructions are for general startup and basic trouble shooting.

For calibration/setting of Standard Interface Board or Pulse Timer, refer to the appropriate instructions.

The positioner is usually supplied internally mounted in the AUMA MATIC Compact (Figure 1). These instructions
also apply if the positioner is remotely mounted. The positioner is programmable for several command and
internal feedback signals. Additionally, the choice of fail modes on loss of these signals can be chosen. Refer to
the programming section (Figure 4) for more information.

The Standard version of the positioner is supplied as a clockwise-actuator output on decreasing-command signal.
Consult the AUMA factory for information on other available configurations.

The convention of clockwise actuator output to close is used throughout this instruction.

General Description

The positioner is an electric controller, employing solid state circuitry, intended for regulating electric motor driven
actuators used on valves, dampers and other devices requiring accurate positioning control. Accurate positioning
is attained through the use of a precision position feedback potentiometer or current device (RWG current
transmitter). The controller drives the motor reversing starters which can be electromechanical (AUMA MATIC-C)
or solid state (AUMA MATIC-S). The controller utilizes a comparator circuit which senses the error between the
input command signal and the internal position feedback signal. The controller then energizes the motor
reversing starter control circuit to drive the actuator in the direction necessary to reduce the error signal to within
the customer set deadband.

Two modes of control are available. In the first mode the motor is continuously energized until the error between
the feedback signal and setpoint is zero. In the second mode (pulse mode) the motor is pulsed based on the
setting of a potentiometer, Time-on (P8), until the error is 25 percent or less. Then the Time-on is reduced by a
factor of 3 through the final 25 percent of error. The initial setting of “OFF” time remains constant. In the pulse
mode the initial “ON” and “OFF” times are field adjustable via the potentiometers P8 and P10.

Note: The AUMA MATIC with positioner generally incorporates a means of remote manual operation using

contact closure. This circuit, using the remote command board, is designed as a secondary input for
push buttons or relay contacts. It is not intended for “modulating” operation when an analog signal is not
available. An interface board is available for use in this case.

AUMA Matic Positioner

Calibration Instruction

The AUMA Matic positioner incorporates the following features for field calibration and commissioning (Figure 3).

ZERO (0/P3) This control adjustment calibrates the positioner to correspond to the lowest command

signal.

SPAN (max/P4) This control adjustment calibrates the positioner to the full 100 percent range of the

command signal.

TIME DELAY This control adjustment is designed to eliminate the positioner
(t-off/P10) from reacting to transient signals. Adjustable delay from 0.5 seconds to 15 seconds.

COARSE SENSITIVITY This control adjustment determines the amount of error signal that occurs before
(∆E/P9) the motor is energized in the direction determined by the input signal, 0.5 to 2.5

percent.

FINE SENSITIVITY This control adjustment determines the amount of error signal that occurs before the
(Sens/P7) motor is energized in the direction determined by the input signal. This is only used for

actuator speeds of 19 RPM and below, where less than 0.5 percent accuracy is
required (0.25 percent minimum).

DIP SWITCH S1-7 Allows command signal (E1) and feedback signal (E2) to be selected.

DIP SWITCH S2-7 Allows controller to position the actuator on loss of command or feedback signal. In

addition, variable pulse width modulation can be selected.

DIP SWITCH S3-7 Selects standard or inverse operation.

Setting of the Sensitivity

• Set selector switch at local controls (Figure 1, Page 2) to position REMOTE.

• Input a random command signal E1. The sensitivity (∆E / dead band) is set to maximum value (2,5 %) in the

factory.

• The sensitivity can be improved or the dead band reduced by turning potentiometer ∆E (P9) clockwise. For a
precise setting of the sensitivity, a set point device with accuracy in the 0,1 mA range is required.

• For actuators with a speed of 19 rpm or less, a better sensitivity (∆E
the potentiometer P7 (sens) clockwise.

NOTE: When setting ∆E the following must be observed: If the number of starts is too high, this will

lead to unnecessary wear at the valve and actuator. Therefore, the maximum possible dead band
acceptable for the process must be set. .

• To prevent exceeding the max. permissible number of starts (refer to Technical data sheet SG,SAR or
consult factory) in extreme cases, a time delay between 0.5s (left stop) and 10s (right stop) may be set with
potentiometer t-off.

Positioner in Split Range version (option)

For Split Range a modified version of the positioner is used. The standard version is not suitable for Split Range
operation.

Split Range: description of functions

Split Range allows the adaptation of the positioner to nominal value ranges which are for example necessary to
individually control several actuators (up to four actuators) with the same nominal value signal. Typical values for
two actuators are 0 - 10 mA and 10 - 20 mA or 4 - 12 mA and 12 - 20 mA. But all other values between 0/4 - 20
mA can also be set and adjusted.

Split Range Programming

Programming of the positioner at the code switches S1-7, S2-7, S3-7 can, with the exception indicated below, be
performed in the same manner as for normal operation.

NOTE: Switch S1-7 DIP 5 at code switch S1-7 must always be in position ON for Split Range version.

Positioner adjustment for Split Range (See also example below)

• Supply the specified minimum input signal (nominal value E1) for the positioner and check by measuring with
Voltmeter at the measuring points MP3 and MP4 (Figure 5).

• Connect voltmeter to measuring points M3 and MP1.
Calculate setting value:
Initial value = E 1

Set initial value with potentiometer P5.

• Supply specified maximum command signal (nominal value E1) and check by measuring at the measuring
points MP3 and MP4.

• Connect voltmeter between measuring point M9 and measuring point MP1. Set 5 V with potentiometer P6.

• Supply input signal E1 from minimum to maximum value and check the set range 0 - 5 V at measuring point

M9. If necessary, readjust with P5 or P6.

• Apply the same procedure to the second actuator’s positioner and set according to the specified nominal
value E1.

• After setting for Split Range operation, perform further readjustment as described in Calibration section, Page 6.

Positioner board A7, Split Range version

Example – Two actuators are to be operated in Split Range version. Actuator 1 must be in position CLOSED with

a nominal value signal E1 of 0 mA, and in position OPEN with a signal of 10 mA.

Actuator 2 must be in position CLOSED with a nominal value signal of 10 mA, and in position OPEN with a signal
of 20 mA. .

• Positioner actuator 1:
Supply E1 = 0 mA, set with P5 = 0 V at M3, supply E1 = 10 mA, set with P6 = 5V at M9.

• Positioner actuator 2:
Supply E1 = 10 mA, set with P5 = 2,5 V at M3, supply E1 = 20 mA, set with P6 = 5V at M9.

• Perform adjustments and settings for E2, as previously described. Afterwards the nominal value E1 can be
transmitted through both actuators (can be connected in series). When operating within range E1 = 0 - 10
mA the actuator 1 moves, actuator 2 remains in end position CLOSED. When operating within range E1 = 10

- 20 mA, the actuator 2 moves, actuator 1 remains in end position OPEN.
