Operating Instructions

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.
