Safety position via energy storage (optional)

AG2

AG3

The safety starting positions in case of power inter-

ruption is realized with the optional energy storage

SAFEPOS energy-pack. The desired position is set

via the menu. In addition to the end positions (open/

closed), any desired intermediate position can be

defined here. The energy storage has a lifespan of

up to 10 years, depending on the operating condi-

tions. The power of the energy storage is monitored

and a warning is displayed to indicate its life is com-

ing to an end. The storage device is designed as a

plug-in module to facilitate replacement. Without

energy storage, the valve remains in the last position

it was in. The energy storage device is fully charged

and ready for operation after a maximum of 120

seconds (depending on the operating conditions).

The energy storage device cannot be retrofitted in

the field.

Fieldbus: EtherNet/IP, PROFINET, Modbus TCP (optional)

The fieldbus gateway for EtherNet/IP, PROFINET

and Modbus TCP is integrated in an additional

module. It has 2 fieldbus connections with 4-pin

M12 circular sockets. The interfaces for the fieldbus

connection and the status LEDs are located under

the gateway housing cover. If there is a need for it to

be include in a network then the configuration of the

Ethernet can be performed via the web server. The

gateway cannot be retrofitted in the field.
