AUMA Matic, MATIC-C, MATIC-S Calibration Instruction

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.

Electrical Connections

CAUTION: Observe safety regulations.

• Verify that the motor and control voltages correspond with equipment supplied. Refer to the nameplate on
motor and/or AUMA MATIC Compact.

• Attach conduit or cables following approved practices.

CAUTION: Appropriate conduit and sealing methods must be followed to ensure the NEMA rating for the

enclosure furnished

• Connect field wiring according to wiring diagram supplied. If drawing is not available, contact the nearest
AUMA office with the Sales Order or Serial Number located on the actuator nameplate. A replacement
drawing will be provided.

NOTE: ACTUATOR LIMIT SWITCHES MUST BE SET USING APPROPRIATE SETTING INSTRUCTIONS
PRIOR TO PROCEEDING.

Logic Board Programming

The AUMA MATIC Compact contains a programmable logic board (Figure 2). The following DIP switch settings
are made on the logic board. The factory has preset the logic board switches per the order requirements

, as

required/or requested, prior to shipment. Typically, no further adjustment is required for proper operation.

Programming

• Refer to Figure 2.

• The Logic Board has 3 sets of switches S1-2, S2-2 and S3-2.

• Switches S1-2 and S3-2 allow for either limit or torque seating in closed and open positions.

Switch S1-2

• In position 1, the actuator is set for limit seating in the clockwise direction.

• In position 2 the actuator is set for torque seating in the clockwise

direction.

Switch S3-2

• In position 1, the actuator is set for limit seating in the counterclockwise direction.

• In position 2 the actuator is set for torque seating in the counterclockwise

direction.

Switch S2-2

Switch Position S2-2 “ON”
S2.1 Remote seal in for clockwise
S2.2 Remote seal in for counter clockwise
S2.3 Local seal in for clockwise

Down is on

Solder links

S2.4 Local seal in for counter clockwise
S2.5 Blinker transmitter off
S2.6 Torque switch included in collective

Also provided on the Logic Board are four solder links. When the soldered link is present on pads J1 and J3, the
integral open and close lights on the Monitor Control board within the AUMA Matic will both be on in a
intermediate valve position. When the soldered link is present on pads J2 and J4 the integral open and close
lights on the Monitor Control board will both be off in an intermediate valve position.

Test Run

• Switch selector switch to local position. If local control is not supplied, refer to electrical drawing for reference
to local operation.

• Turn control switch or operate push-button in either open or close direction.

If actuator fails to operate, verify the following possible conditions.

NOTE: 3Ø AUMA MATIC compacts incorporate a phase discriminator. If AUMA MATIC fails to respond to local

and remote operation, reverse U1 and W1 at field terminals.

NOTE: Actuators shipped after March 2002 incorporate automatic phase correction.

• No line power.

— Check for loose connection.
— Check for correct voltage at terminals U1, V1 and W1.
— Check for correct capacitor connection (1Ø only), if required.

• Field jumpers are not correct.

— Verify the field wiring matches electrical drawing supplied by AUMA.

• Fuses are open.

— Remove selector switch/push-button cover (Figure 1). Primary fuse(s) are located in black fuse holders.
— Secondary fuses are located on power supply board which can be accessed by removing the monitor

CAUTION: Before checking/replacing fuses, ensure all power is disconnected.
