5.2 Faults in initialization mode
Nothing displayed after being switched on
Possible cause:
R Power supply cable with open circuit
R Connection between circuit board M1 and power
module is interrupted
R Device fuse is defective
R Auxiliary voltage is defective
R Circuit board M1 is defective
Remedy:
1. Check the power supply unit for continuity.
2. Replace the power supply cable if there is a
malfunction.
DANGER – Risk of electric shock from live
parts. Observe the electrical engineering safety
regulations.
3. Establish and secure connection between circuit
board M1 and power module 1 (see sec. 6).
4. Check mains voltage at power module 1 and power
module 2 at measuring points M1 and M2 (see sec.
5.6).
 Mains voltage must be 230V.
 Device fuse is defective if mains voltage differs.
5. Replace corresponding power module if mains
voltage differs.
6. Check auxiliary voltage at power module 1 and
power module 2 at measuring points IC 14 Pin 1 and
GND1 Pin 4 (see sec. 5.6).
 Auxiliary voltage must be 12V.
7. Replace corresponding power module if auxiliary
voltage differs.
8. Connect customer service circuit board M1 to power
module 1 and BAT 690 check function.
 If BAT 690 functions with the customer service
circuit board M1, the M1 circuit board of the cus-
tomer is defective.
9. Replace the customer's M1 circuit board.
10. Define power module 1 with jumper setting as Slave
1 (see sec. 4.4.4).
11. Connect power module 2 to circuit board M1 and
BAT 690 check function.
 If BAT 690 functions, power module 1 is defec-
tive.
 If BAT 690 does not function, power module 1
and power module 2 are defective.
12. Replace power module 1 and/or power module 2.
