[14] Engine coolant temperature
Indicates an abnormality of engine coolant temperature.
It is normal if the monitor remains OFF during operation.
Engine coolant temperature is exceeding the normal value
if the monitor lights up during operation.
Set the engine speed to low idle immediately and wait until
the monitor goes OFF (engine coolant temperature drops).
Then, stop the operation and check the radiator for water
leakage, radiator core for clogging and alternator belt for
damage and tension.
[15] Charge
Indicates an abnormality of the charging system.
If the charging system is normal, the monitor lights up
when the starter switch is set to the “ON” position and goes
out as engine speed increases after engine start.
The charging system has an error if the monitor lights up
during operation.
Stop the operation immediately and check the alternator
belt for tension.
[16] DPF regeneration request lamp
While the DPF will carry out automatic regeneration, the
filter may not be regenerated if the machine is idling with
no load or operations with low load is repeated.
In this case, the DPF regeneration request lamp on the
monitor is lit.
If the DPF regeneration request lamp is lit, carry out
manual stationary regeneration.
For the procedures for stationary regeneration, refer to
“OPERATION 2.27 DPF STATIONARY REGENERATION
METHOD” section.
[17] Exhaust temperature alarm lamp
This is used to let the operator know that the exhaust gas
temperature is at high temperature due to reset/stationary
regeneration.
Lights up when reset/stationary regeneration is in
operation.
[18] DPF regeneration lamp
During DPF regeneration, the DPF regeneration lamp is lit
on the monitor.
Regardless of whether the filter is undergoing Reset
Regeneration (automatic regeneration) or Stationary
Regeneration (manual regeneration), the regeneration
lamp is lit.
