• In case there fuses were blown before, first check
the wiring to and from the transformer and blo-
wers. Also check discoloration of the transformer.
• Select X6 and push OK
In case the fuses F1 or F2 still blow, switch off the
mains supply and proceed as follows.
1. Disconnect the 2 capacitors and unscrew them from
the blower suction channel. (Metric 13)
2. Remove the grommet and take out the hose.
3. Unscrew 2 nuts (metric 10) and 2 bolts (with nut,
metric 8) and remove the blower suction channel
4. Connect the 2 capacitors.
5. Disconnect both blowers. Therefore disconnect wire
60 from terminal X3.
6. Switch ON the mains supply and activate output X6.
7. In case the fuses still blow, the transformer is broken
or the wires to and from the transformer maybe
shorted.
8. In case the fuses stay, then check the voltages accor-
ding the previous page, in the high speed table.
9. In case these voltage differ, the transformer is bro-
ken.
10. In case the voltages are OK, one or both blowers
have a short circuit, or the wires to the blowers
may be shorted.
11. Switch OFF the mains supply (power) and discon-
nect the wires 61 and 68 from the screw terminals
of the lower blower and insulate them.
12. Re-connect wire 60 to terminal X3 on the pcb.
13. Switch on the power and activate output X6.
14. In case the upper blower is running normally, the
lower blower is broken.
15. Check the running blower by measuring the cur-
rent. This is 0,85A
16. In case the blower is not running, the capacitor
might be broken. The current will than be 1,7A.
16. Switch off the power and exchange the broken
blower.
17. Re-connect all wires on the blowers, activate
output X6 and check the transformer voltages and
blower current.
Note that in case an insulation tester was available, a
broken blower would have been detected already
with the resistance values. See page 48.
