807 1 1 Time out of LSB message (message no. = parameter)
Possible cause of error:
–
connection between VSM/LCM GND and protective earth PE
– acknowledgment of speed change too fast / fault of VSM
– error at LSB (red LED flashes or is permanently ON)
889 0 0 The gap between two remote fault releases is too short
EN 14459 allows only 4 remote fault resets every 15 min.
Fault release is monitored by remote control software, LAMTEC
SYSTEM BUS and field bus. Exceeding the number of fault releas-
es causes the fault shot-down H889 and further remote fault releas-
es are ignored.
After a delay time another remote fault release is possible.
The fault shut-down H889 also occurs, if fault release is sent with-
out any reason. A reset by terminal is always possible.
How to reset this fault:
–
wait for 15 minutes until you try to reset the fault again
– cut off the power supply from BT300 for a moment, reconnect it
and reset the fault subsequently.
