Temperature on the housing is too high
It may become necessary to disassemble the coolant supply for maintenance
measures or troubleshooting.
●
This work may only be carried out by skilled personnel.
●
Do not carry out any maintenance measures while the machine is run‐
ning. Comply with the safety instructions.
●
Protect open supply lines and connections against ingress of dirt.
WARNING

ning.
●
Switch off the controller and the machine and wait until the discharging
time of the electrical systems has elapsed before starting troubleshoot‐
ing.
●
While carrying out maintenance work, secure the machine such that it
cannot restart or be used by unauthorized persons.
●
Do not work on hot surfaces.
Possible causes for the malfunctioning of BA1N energy storage device can
be limited to the following areas:
●
Cooling circuit or fan function and temperature behavior
●
Internal temperature sensor
●
Encoder or encoder connection
●
Mechanical damage of the BA1N energy storage device
●
Mechanical connection to machine
The encoder connection and the temperature sensor are monitored by the
controller or the control unit; corresponding diagnostic messages are dis‐
played. Comply with the instructions in the corresponding documentation.
The sections below describe examples of some fault states along with possi‐
ble causes. This list is not exhaustive.
State
The housing temperature of the energy storage device rises to unusually high
values.
NOTICE
●
Liquid-cooled energy storage devices may not be restarted or supplied
with cold coolant immediately after a failure of the cooling system or an
increase in motor temperature
●
Before restarting the energy storage device, wait until the surface tem‐
perature has dropped to approx. 40 °C.
Operation of BA1N energy storage device
Risk of injury due to moving elements! Risk of
injury due to hot surfaces!
Damage to the energy storage device or ma‐
chine by restarting after excessive tempera‐
ture!
