8U_ 8 Voltage decrease protection
8f, 8 Frequency increase protection
8f_ 8 Frequency decrease protection
Cause
Measured voltage, frequency
or the vector shift is too large
or too small
Too high internal
measurement deviation of the
two measuring channels
Error internal regulation
Communication error internal
interface
Error feedback contacts
Hysteresis error:
overlapping of the release
points
Configuration error
If a OFF-delay 8dof 8
active, the time runs down in
the display (the shortest one
first)
Code lock / Sealing activated
Pr selected with N, but N not
connected
Sealing is active
Code lock is active
Standby mode, E1-E2 closed
Remedy
Consider the measuring range
Perform a reset 
interrupt the control supply voltage
for >5 s
Feedback contacts not connected
- set 8trel.8
Feedback contacts connected
- check the correct connection
- Adjust the turn-on time of the section
switch under
- Perform a reset  interrupt the control
supply voltage for >5 s
Upper threshold value must be higher than
the lower threshold value, check the
threshold values
Reset to factory settings, see "Program
setup"
is
Wait until the time is complete
(depending on the setting, several times
may elapse one after the other)
When having problems with the code lock
(Pin forgotten), the lock can be
deactivated and the pin can be reset to
504 , by pressing the button
