2.
The engine RPM is below high idle. If the pump is
turning too slow, the oil flow rate required for the
belt RPM setting may not be achievable. Increase
engine RPM.
3.
There may be a problem with the RPM sensor. The
control system requires feedback from the RPM
sensor to maintain the desired belt speed. Check the
sensor gap or replace the RPM encoder.
4.
The coil on the belt hydraulic valve may be faulty or
the valve may be sticking reducing the required oil
flow rate to the motor.
Cement auto alarm. This alarm
indicates the control system cannot
reach the set point. This alarm will shut
off the mixer operation. The cement
motor speed is based on the mix design
ratio and on the belt motor output
flow. For this reason, the cement motor
may be unable to reach its required
speed if the belt speed is very slow and
the cement ratio is also very low. Other
causes for this alarm unrelated to belt
speed are:
1.
There may be a problem with the RPM sensor. The
control system requires feedback from the RPM
sensor to maintain the desired cement speed. Check
the sensor gap or replace the RPM encoder. The
operator can manually over-ride the cement control
valve to a “full” or 100% open position. More cement
powder will be consumed if the mix design is a lean
mix.
2.
The coil on the cement hydraulic valve may be faulty
or the valve may be sticking reducing the required oil
flow rate to the motor. If the problem is a faulty coil,
the operator can manually override the valve and set
the desired cement ratio on the mixer control screen
using the “Actual” value shown in the rpm field. This
is a temporary solution and should be done with a
fixed belt speed.
Radio remote has lost link to the
receiver. This is typically caused when
batteries need to be replaced or the
remote is too far away from the
receiver. If this alarm is activated the
machine will stop. The operator must
acknowledge the alarm by pressing the
belt button on the mixer control knob
(#5). The machine can then be run
without the wireless.
Colour auto alarm. This alarm indicates
the control system cannot reach the set
point. This alarm will shut off the mixer
operation. The colour motor speed is
based on the mix design ratio and on
the belt motor output flow. For this
reason, the colour motor may be
unable to reach its required speed if the
belt speed is very slow and the colour
ratio is also very low. Other causes for
this alarm unrelated to belt speed are:
1.
There may be a problem with the RPM sensor. The
control system requires feedback from the RPM
sensor to maintain the desired colour speed. Check
the sensor gap or replace the RPM encoder. If
manual operation is desired, then the operator will
need to confirm the correct ratio by visual inspection
of the product colour. A fixed belt speed will help
achieve this.
2.
The coil on the colour hydraulic valve may be faulty
or the valve may be sticking reducing the required oil
flow rate to the motor. If the problem is a faulty coil,
the operator can manually over-ride the valve and
set the desired colour ratio on the mixer control
screen using the “Actual” value shown in the rpm
field. This is a temporary solution and should be done
with a fixed belt speed.
Aux1 or Aux2 auto alarm. This alarm
indicates the control system cannot
reach the set point. This alarm will shut
off the mixer operation. The aux motor
speed is based on the mix design ratio
and on the belt motor output flow. For
this reason, the aux motor may be
unable to reach its required speed if the
belt speed is very slow and the aux
ratio is also very low. Other causes for
this alarm unrelated to belt speed are:
