Safety Note

To avoid personal injury and damage to the device or other property, it is necessary to read and follow these instructions carefully. Assembly, start-up, and maintenance work] must be performed by qualified and authorized personnel. Comply with the instructions of the system manufacturer or system operator.

• Do not remove the cover before the power supply is fully switched off.

Mounting Position

• The actuator should be mounted with the valve stem in either a horizontal position or pointing upwards.

Wiring

AC 24 V

• Connect via Class 2 (North America) or Safety Extra-Low Voltage (SELV) (Europe). Failure to comply can lead to equipment damage or personal injury.
• Switch off the power before wiring the actuator!

1. Make all wiring connections in accordance with local, national, or regional regulations.
2. For applications requiring conduit, a field supplied 1/2” trade size electrician’s fitting and lock nut can be mounted in the actuator enclosure. Use flexible metallic tubing or its equivalent with the field supplied fitting.
3. Insert wiring material through the removable plug or conduit fitting, and connect to the terminal block using the applicable wiring diagram.

Installation

1. Depending on the version of actuator (SU/SD) prior to installation an included washer and adapter are required to be installed: SD, Washer (003Z0257) The washer is placed on the valve neck prior to the installation of the actuator. SU, Adapter (003Z3960) and washer (003Z0257) Hand tighten the adapter to the neck of the valve. The actuator will be installed to the adapter.
2. The actuator should be in the full up position ① (factory setting). If it is not, refer to the manual override instructions ❸④.
3. The actuator is fixed to the valve body or adapter by means of a union nut which requires Nan adjustable wrench to assist in tightening the actuator to the valve.

DIMENSION

DIP switch settings

Factory settings

• ALL switches are on the OFF position!
  (except SW7 which is in ON position)!

NOTE: All combinations of DIP switches are allowed. All functions that are selected are added consecutively. There is only one logic override of functionalities i.e. switch No.6 Proportional /3 point, which sets the actuator to ignore the control signal and works as a “simple” 3-point actuator.

SW 1: VDC / mA – Input signal type selector

• If set to OFF position, voltage input is selected. If set to ON position, current input is selected.

SW 2: 0/2 – Input signal range selector

If set to the OFF position, the input signal is in the range from 2-10 V (voltage input) or from 4-20 mA (current input). If set to the ON position, the input signal is in the range from 0-10 V (voltage input) or from 0-20 mA (current input).

SW3: D/I – Direct or inverse acting selector

• If set to OFF position, the actuator is direct acting (stem retracts as voltage increases). If the actuator is set to ON position, the actuator is inverse acting (stem extends as voltage increases).

SW4:—/Seq – Normal or sequential mode selector

• If set to OFF position, the actuator is working normally in 0(2)-10V or 0(4)-20mA range. If set to ON position, the actuator is working in a sequential mode with its range dependent on the position of SW 4.

SW5: 0-5 V/5-10 V – Input signal range in sequential mode

• If set to OFF position, the actuator is working in sequential range 0(2)-5 (6) V or 0(4)-10 (12) mA. If set to ON position, the actuator is working in a sequential range; 5(6)-10 V or 10(12)-20 mA.

SW6: Proportional/Floating point

If set to ON position, the actuator can operate as a Floating point actuator. The power supply should be connected to SN and SP ports. On port 1 or 3 24 VAC signal is connected for rising or lowering of actuator. Return signal X indicates the correct position. If set to OFF position, the actuator operates on modulating input signal.

NOTE: if 3 point function is selected actuator does not respond to any control signal on port Y. It only rises and lowers the spindle if power is supplied on port 1 or 3.

SW7: LIN/LOG – Linear or equal percentage flow through valve selector

• If set to the ON position, the flow through the valve is linear to the control signal.
• If set to OFF position, the valve position is equal percentage acc. to the control signal.

Note: It is generally recommended to configure the AME 13 actuator for operation in linear mode (SW7 set to ON).

SW8

• Set to ON for valve bodies 1/2” to 1-1/4” HF. The actuator will modulate on max stem travel of 4.5mm.
• Set to OFF for valve body 1/2” Low flow. The actuator will modulate on max stem travel of 2.5mm.

SW9: Reset

• Toggling the switch will cause the actuator to go through an auto-calibration cycle.

Function test

The indicator light shows whether the positioner is in operation or not. Moreover, the indicator shows the control status and faults. Constant light

• normal operation

No light

• no operation or no power supply

Intermittent light (1 Hz)

• self adjusting-mode

Intermittent light (3 Hz)

• power supply too low
• insufficient valve stroke (<20 s)
• end-position cannot be reached.
