Deactivation of the digital output PFU:
• Power feedback unit switches to standby mode
The time between the end of travel and activation of the PFU output can be speci
fi
ed with the
Encoder & BC/T_PFU
parameter.

Waiting time PFU PWM
If the parameter
T_PFU
is set to
0s
, the output PFU is always active.
Standby is now deactivated.
1 s after deactivation of the digital output PFU the power feedback unit is ready for operation again
(see diagram).

14.2.1.3 Power feedback unit in connection with automatic emergency evacuation.
CAUTION!
In lift systems with automatic emergency evacuation by a single-phase mains supply (emer-
gency power supply unit/UPS) or battery (EVAC 3B) the power feedback unit is not active due
to the too operating voltage failure. To avoid too high a voltage in the intermediate circuit when
evacuating by a generator run, a brake resistor must be used in addition to the power feedback
unit!
