2.2. Short description
In emergencies, the fail safe unit is capable of closing or opening the valve
autonomously relying on mechanical functions.No electrical power is required for
such a fail safe operation.The torque required for opening or closing the valve is
generated by a constant force spring motor, providing a constant torque across the
total travel during fail safe operation.Consequently, the torque value for a fail safe
operation is determined by the available torque of the fail safe unit and is independent
of the actuator torque range.
For standard valve operation, the FQM fail safe unit is combined with an AUMA SQ
part-turn actuator.The required torque is transmitted directly from the actuator through
the fail safe unit to the valve. During standard operation, the constant force spring
motor of the fail safe unit is disengaged and is not operated.
The operating speed for the fail safe operation can be set in the factory.Furthermore,
the actuator operates the valve into the defined end position at reduced speed.This
avoids pressure peaks within the pipeline and protects the valve.

4. Assembly
4.1. Mounting position
The product described in this document can be operated in vertical and horizontal
mounting position.The mounting position pointing downward is not permitted. For
horizontal mounting position, the fail safe unit requires reinforcement to relieve the
flange connection to the valve.
Figure 6: Reinforcement for horizontal mounting position (example)
The reinforcement is made at both threads provided for transport. For FQMEx
05.1/07.1 = 5/8”UNC thread (M10 metric thread); for FQMEx 10.1/12.1 = 1/2”UNC
thread (M12 metric thread).
We recommendapplyingliquid threadsealingmaterialtothe screwsto avoidcontact
corrosion in the thread.
To compensate for vibration, we recommend using additional all-metal dampers as
available with Stop-Choc ®.
Support by AUMA AUMA offers an own support.The support is fixed at the output drive flange using
suitable fastening clamps.It includes all-metal dampers to compensate for vibration.

directly from the Internet (http://www.auma.com).
Protection on site For short-circuit protection and for disconnecting from the mains, fuses and disconnect
switches have to be provided by the customer.
The current values for respective sizing are derived from the current consumption
of the motor (refer to electrical data sheet), the current consumption of the actuator
controls, plus the current consumption of the fail safe unit. Please refer to the
operation manual pertaining to the actuator for information on the current consumption
of actuator controls.
When providing joint protection for actuator, actuator controls and fail safe unit, the
maximum power consumption of 360 W for the fail safe unit has to be accounted
for. In case separate power supply for the fail safe unit is provided, 360 W have to
be accounted for FQM protection.
Consider increased power supply starting current when selecting the circuit breaker
characteristic.We recommend tripping characteristics D or K for circuit breakers in
accordance with IEC 60947-2.To avoid spurious action, fuses with values below 2
A are not recommended.
5.2. Electrical connection of actuator/actuator controls
The customer connection for valve control during standard operation (power
connection and signal cables) is made via the electrical connection of the actuator
or the actuator controls.Any procedures for opening/closing the terminal compartment
and for connecting the cables are described in the operation manual pertaining to
the actuator.
