Maintenance / Technical Data
Function and Fault Indicators on Ballast Units
The three red LEDs on the ballasts serve the purpose of checking function and troubleshooting.
All three LEDs light up for approx. 1 second when the supply voltage is applied.
LED “Power Supply” (identification on pc-board “Power”)
ON Ballast power supply is OK
OFF Although the master switch is on and the power plug is connected
➤ Check power supply (only by authorised electrician!)
➤ Check fine fuse
LED “Lamp” (identification on pc-board “Error”)
Flashes for
approx. 1 to 15 sec Lamp electrodes are preheated before ignition
ON UV lamp inoperative
The LED goes out by switching the power supply off and on again and comes on again after a
renewed ignition attempt
➤ Check lamps
LED “Bus” (identification on pc-board “Tx”)
Lights up every 0.1 to 3 sec The ballast is addressed by the control.
Does not light up Although the system is switched on:
The bus connection to the ballast is interrupted or the ballast is defective
IMPORTANT!
Since the data bus is designed as a bus with ring structure, the ballasts following a
defective ballast or interrupted data line can no longer be addressed.
