UPS evacuation
In UPS mode, the ZArec4C cannot feed any energy back into the supply network. The energy created
during generator travel is completely discharged via the brake resistor. This enables travel to continue
at a reduced speed for a limited period in case of mains failure.
•
Single-phase UPS: See connection diagram in "Electrical installation/circuit suggestion, ZArec4C
and ZAdyn4C - UPS evacuation"
•
Three phase UPS or diesel generator: See connection diagram in Chapter 5.19
If all three phases of the line connection voltage at terminal X1 fail, the ZArec4C automatically shuts
down the recovery function. If the recovery function is to be shut down regardless of the line
connection voltage, this can be done using the digital input CL. To do this, the parameter
Default
settings/f_CL
should be set to
LockRec
.
During commissioning, the correct function when switching between normal mode and evacuation
mode must be checked.
For further information on UPS evacuation, refer to the "Emergency evacuation" and "Energy saving/-
power feedback unit in conjunction with automatic emergency operation" chapters in the ZAdyn4C
operating instructions.

Function
•
The ZArec4C automatically switches to standby mode after an adjustable period of time.
•
To activate the return feed function, 24 VDC are switched to the EN digital input via a potential-free
contact.
•
The ZArec4C has an internal 24 VDC voltage supply for this purpose.
•
EN may only be activated after the RDY output is active.
•
EN must be deactivated within 1 s after switching off the RDY output.
