Energy storage SAFEPOS energy-pack (option)

The device can also be equipped with the energy storage system (SAFEPOS energy-pack). In the event of a
supply voltage failure, the energy storage system supplies the actuator with the energy required to move the
valve to the safety position.
The safety position is set using the DIP switch or via the display module..
After a maximum of 120 seconds (depending on operating conditions), the energy storage is fully charged
and ready for operation
7.3.1 Service life
Service life: up to 15 years (depending on operating conditions).
The service life of 5 years was calculated based on the following conditions:
Ambient temperature
Medium temperature
Duty cycle
Operating pressure
Nominal diameter
NOTE!
The energy storage system SAFEPOS energy-pack is a wearing part. The service life figures are approx-
imate values that cannot be guaranteed.
7.3.2 Notifications on the state of the SAFEPOS energy-pack
The device issues a warning:
The capacity of the energy storage is strongly decreased. The energy pack needs to be replaced soon.
▶
The SAFEPOS energy-pack must be promptly replaced before the end of its service life.
The device issues an error alert and assumes the safety position:
The SAFEPOS energy-pack was not promptly replaced before issuance of the warning. The storage
capacity is so low that assumption of the safety position can no longer be guaranteed.
7.3.3 Replace SAFEPOS energy-pack (AG2)
CAUTION!
Risk of injury due to electrical voltage.
▶ Turn off the supply voltage before removing the SAFEPOS energy-pack.
▶ Ensure that the SAFEPOS energy-pack is fully discharged. Wait until the LED ring is no longer lit and ensure
that the LED status is not in "LED off" mode (see chapter "12.2.1 LED illuminated ring").
The SAFEPOS energy-pack energy storage system is located in the actuator housing. Remove the following
parts from the actuator for replacement:
30 °C (AG2) / 60 °C (AG3)
165 °C
100 %
5 bar
DN32 (AG2) / DN65 (AG3)
