IMET - M550 ALL1-EN 29/53
6.6. Meaning of LEDs
The
radio remote control is provided with LEDs (light-emitting
diodes) that provide the following information:
• Operating status
• Operating malfunctions
• Type of malfunction
• Battery exhausted (except M8)
Transmitting Unit
LED status Meaning
Off
Transmitter off or malfunctioning (see Chap. 8)
On
Transmitter working.
Flashing at regular intervals
Battery exhausted (except M8)
Flashing with regular number of
flashes
Transmitter is in analog output calibrating mode (see the
manual on calibrating the analog outputs)
Coded flashing
Radio remote control error – contact Service Centre
Rapid flashing
Malfunction in STOP circuit (see Chap. 9)
One short flash
EEPROM missing or not working
Receiving Unit
LED Function
Data Error ch. A
(yellow LED)
On during operation
Off during data errors on channel A
Passive Emergency ch. A
(red LED)
Off during operation
On when channel A is STOPPED
System errors are indicated by coded flashing (similar to Morse code)
Data error ch. B
(yellow LED)
On during operation
Off during data errors on channel B
Passive Emergency ch. B
(red LED)
Off during operation
On when channel B is STOPPED
System errors are indicated by coded flashing (similar to Morse code)
RF busy
(green LED)
On when channel is occupied by radio signals Rapid flashing during dual
transmission
Power Supply
(green LED)
On when power supply is present
Working
(green LED)
On when the two E-STOP relays are closed and the controls are enabled
