2 Introduction

AUMA India has developed a new range of electric actuators with intelligent integral
starter using microcontrollers for weatherproof applications that has the ability to store
events and other upgraded features. The actuators support both ON-OFF and Regulating
Duty and can also be run in Inching or Non-Inching mode depending on the selection.

The important features of these electric actuators are as explained below:

LCD graphical display &

LED indication

Options can be selected by using the selector switches, rotating knob based on the
instructions displayed on the LCD screen. Information on faults/statuses can be obtained
from the 6 LEDs next to the LCD. The 6 LEDs are conﬁgurable as per user requirement
before-hand. LCD screen facilitates easier understanding of status, operation and
parameter setting details. More information regarding this is described in section 3.

Inbuilt front panel option

selection

Different features/options of the actuator can be conﬁgured using software. This is done
using the selector switches, rotating knob based on the instructions displayed on the LCD
screen that is present on the front panel. More information regarding this is described in
section 3.

Interfaces

These actuators are capable of supporting different types of interfaces like Remote – 4
Wire / 2 Wire Make/Break, 4-20 mA Regulating Duty, Bluetooth & MODBUS-RTU.

Emergency stop - ESD

ESD feature is conﬁgured to run in Close direction on enabling ESD as a default setting.
One needs to enable ESD and set its behavior in Program Mode for it to function. An
ESD via MODBUS option is also available that needs to be enabled in Program Mode.
ESD Operation can be conﬁgured for OPEN/CLOSE/STAY. One can choose to set ESD
on TOLR Ignore, TH Ignore, Space heater Fail Ignore, OFF Ignore. This means that ESD
operation would occur irrespective of these faults. One must enable ESD on program
mode and set its behavior (ESD Open/Close). An ESD NO/NC conﬁguration is also
available that can be conﬁgured in Program mode. ESD feature now can be carried out
using an external 24VDc supply also.

Event storage & data

logging option

These actuators comes with an option to store events such as faults, statuses, number of
starts (Open in Local/Remote) etc. using a Bluetooth module. The events are stored in a
ﬂash memory and can be read via Bluetooth. The data logged will have a real time stamp
and can be downloaded using a user-friendly application called AUMA India Utility
Software onto a PC/ Laptop with Bluetooth connection. About 43691 events can be
stored at a time using this module. AIUS is also used in assisting commissioning and
diagnosing the actuators. Device Tag is customer conﬁgurable. Remote Operation of
actuator through Bluetooth is also available.

The available events are as follows:

●

Number of Starts (Open and close in speciﬁed duration)

●

Open and close Command with Selector Switch Position

●

Tripping Torque Proﬁle (Non-Intrusive)

●

Faults.
