The First Switch-On
In case you use the DiMAX
®
1203 Booster with a central station,
the central station must be
switched on first.
Switch on the power supply for the DiMAX
®
1203 Booster.
After the power up the LED indicators switch from red to green. The lower green LEDs will be
illuminated provided the central station is not in the emergency stop mode and the booster is
connected correctly to the central station.
This shows that the data transfer to the central station is established.
4.1 Changing the Operation Modes
Keep the mode key depressed while pushing the reset button once. Then release both but-
tons.
The respective channel will change to the next mode.
The sequence is: booster - booster with reversing loop - booster with braking function.
4.2 Overvoltage Protection
The overvoltage protection of the DiMAX
®
1203 Booster has been activated if all three red top
LEDs are illuminated. In this case the supply voltage is too high, and the booster switches off
for safety reasons. Make sure to operate the DiMAX
®
1203 Booster within the specifications.
Disconnect the DiMAX
®
1203 Booster briefly from the power source to reset the system.
4.3 Overload Protection
In case one or more channels
are showing a flashing red LED, the respective channel has
been switched off due to high amperage. Make sure to eliminate the cause of this failure and
reset the faulty channel by depressing the RESET button for about 2 seconds.
4.4 Loss of Signal from the Central Station
Flashing green LEDs indicate that the data connection to the central station is faulty. Check
the booster cable from the central station to the DiMAX
®
1203 Booster respectively the
connection from the booster to the Central-Navigator (see note page 2).
4.5 Adjustment of the Output Voltage
The voltage regulator on the rear panel regulates the output voltage of all outputs from
14Volts to 22Volts.
This regulator works only if the input voltage is AC!
