LB-762 Controller Installation Manual
LAB-EL
during daily operation are located on the front panel of the regulator casing.
The following LEDs are available:
RDY
regulator readiness to work
ETHERNET LNK
Ethernet connection (LED out - no connection, LED on - connection active)
ETHERNET ACT
data transmission through Ethernet interface (each LED flash is associated with data receipt or transfer)
ETHERNET SPD
data transmission speed through Ethernet interface (LED out – 10 MBit/s, LED on - 100 MBit/s)
BELIMO MP
data transmission through interface of servomotors BELIMO MP (each LED flash is associated with data receipt or
transfer)
RS-485 RX
receipt of data through RS-485 interface
RS-485 TX
sending of data through RS-485 interface
S300 #1
data transmission through interface S300 no. 1 (each LED flash is associated with data receipt)
S300 #2
data transmission through interface S300 no. 2 (each LED flash is associated with data receipt)
2.2.1
Errors in operation
Errors in operation of the regulator are signalled both on the display on the the front panel as well as by means of signaling
diodes on the main plate of the regulator (possible is e.g. regulator failure condition which does not permit display of the
relevant announcement on the displays, in such case the only possible signaling is by means of diodes on the plate).
Errors are announced as follows:
2.2.1.1
Front panel
On the main display located on the front panel the message is displayed
SOS XXXX
, where XXXX may have different numeric
values, denoting the error code.
ALARM diode and buzzer (sound signaling) broadcast SOS message in the Morse alphabet.
2.2.1.2
Signaling LEDs on the main plate
The following LEDs are used to signal failure: RDY, ETHERNET LNK, ETHERNET ACT and ETHERNET SPD. LEDs
flash in cycles broadcasting SOS message in the Morse code, similarly to the signalling on the front panel. The error code is
characterized by a combination of diodes which flash and which remain off.
