Operating Instructions
GB
There are two diode lamps on the MCU:
The green diode lamp indicates that
there is a 12 V supply to the PCB.
As long as the monitoring circuit is intact, the MCU ensures that a small
12 V relay remains connected. The 12 V relay supplies all remaining
units which take energy from the battery, e.g. the key switches, main
and pump relays.
The MCU monitors the cell circuit. If the circuit is broken, the red diode
lamp flashes. After 10 seconds, the relay is disconnected and the red
diode lamp lights up.
The MCU is disconnected if the main switch is disconnected.
The red diode lamp indicates that the
monitoring circuit is broken, i.e. that
there is a problem with at least one of
the cells.
MCU diode lamps
A break in the MCU circuit can be caused by a cell with excessively
low voltage. If this is the case, recharge the battery. Press reset button
briefly.
Resetting the MCU
Insufficient cell voltage
Open main switch
If there is a break in the MCU circuit caused by the main switch having
been opened, just press the reset button briefly. The truck does not
need recharging.
If the MCU is triggered during charging, the charging voltage may
be too high or the battery imbalanced. Try pressing the reset button
repeatedly.
If one of the red cell sensor diode lamps lights up much earlier than the
others, the voltage in this cell is too high. The cell may be damaged.
If the cell is damaged, contact GMR maskiner a/s.
Excessive charging
voltage or imbalanced
battery
Stama trucks with no reset
button (after 2014)
Stama trucks which do not have a reset button are fitted with a simple
BMS, in which the MCU is replaced by a simple BMS relay, which
requires no resetting. If all the battery sensors light up green, the
BMS relay is activated and the machine can be started. If just one of
the sensors does not light up green, the relay is not activated and the
batteries will not be excessively discharged.
