In case of alarm follow this procedure:
1. load default values for eeprom variables, both using PC with serial communication
software and COMPACT display;
2. replace the control board .
Pre-charge capacitors low voltage alarm (Capacitors not charged)
-
Eye alarm code: 6
-
Alarm level: 1
-
Alarm cause: voltage level of pre-charge capacitors is less than 70 % of nominal battery
level.It could happen, in example, if the inverter is working with main breaker open.
Capacitors voltage decreases cause energy spent to keep motors in motion.
In case of alarm follow this procedure:
1. verify if main breaker coil and power terminals are in good conditions;
2. verify if supply lines power fuse is damaged;
3. verify if main breaker coils are correctly wired to their correspondent inputs :
K1-18 (positive terminal)
K1-19 (negative terminal)
4. replace main breaker;
5. replace control board.
Inverter desaturation or overcurrent alarm
-
Eye alarm code: 8 for right drive motor power module
24 for pump motor power module
25 for left drive motor power module
-
Alarm level: 1
-
Alarm cause: actual current exceeds limits 929 A
In case of alarm follow this procedure:
1. With such an alarm present when you turn on lift truck, disconnect the power
cable between the malfunctioning inverter and the corresponding motor (first, turn
off the system, of course).
