Failure code [7RJSMA] Abnormality in magnetic separator pressure
sensor
1
User code
Failure code
Trouble
Abnormality in magnetic separator pressure sensor
(Work equipment and pump controller (work equipment control) system)
—
7RJSMA
Contents of
trouble
• Signal voltage from the magnetic separator pressure sensor is below 0.3 V or above 4.42 V.
Action of
controller
• Mistakes the magnetic separator pressure for 0 MPa.
• If cause of failure disappears, system resets itself.
Problem that
appears on
machine
• Whole work equipment does not stop completely even if abnormal load is applied to the magnetic
separator.
(Primary conveyor, crusher, feeder, muck discharge conveyor, magnetic separator, vibratory screen
and secondary conveyor)
• Horn sounds (three intermittent sounding) upon detecting a failure.
Related
information
• If 5V circuit (3) and ground circuit (1) of pressure sensor are connected inversely, pressure sensor
will be broken. Accordingly, take extreme care when checking.
• Signal input from the magnetic separator pressure sensor can be checked with the monitoring func-
tion (Code:
24401
, Mag. Pressure).
• The failure history is recorded.
Possible
causes and
standard value
in normal state
Cause
Standard value in normal state/Remarks on troubleshooting
1
Defective 5 V power
source system
If failure code [
DA25KP
] is displayed simultaneously, carry out trouble-
shooting for it first
2
Defective magnetic
separator pressure
sensor (Internal failure)
a
Prepare with engine starting switch OFF, then turn engine starting
switch and carry out troubleshooting.
S03 (male)
Voltage
Between (1) and (3)
4.5 – 5.5 V
Between (1) and (2)
0.3 – 4.5 V
If the voltage is normal, replace with another pressure sensor (pressure
sensor of conveyor etc.) and check if failure codes are displayed. (If the E
mark of the failure code disappears, the magnetic separator pressure sen-
sor is defective.)
3
Disconnection in wir-
ing harness (Discon-
nection or defective
contact in connector)
a
Prepare with engine starting switch OFF, then carry out troubleshooting
without turning engine starting switch ON.
Wiring harness between C01 (female) (7) – A03
– S03 (female) (2)
Resistance Max. 1
z
Wiring harness between C01 (female) (4), (10) –
A03 – S03 (female) (1)
Resistance Max. 1
z
Wiring harness between C01 (female) (22) – A02
– S03 (female) (3)
Resistance Max. 1
z
4
Grounding fault in wir-
ing harness (Contact
with ground circuit)
a
Prepare with engine starting switch OFF, then carry out troubleshooting
without turning engine starting switch ON.
Wiring harness between C01 (female) (7) – A03
– S03 (female) (2) and chassis ground
Resistance Min. 1 M
z
5
Hot short in wiring har-
ness (Contact with 24V
circuit)
a
Prepare with engine starting switch OFF, then turn engine starting
switch ON and carry out troubleshooting.
Wiring harness between C01 (female) (7) – A03
– S03 (female) (2) and chassis ground
Voltage
Max. 1 V
Wiring harness between C01 (female) (22) – A02
– S03 (female) (3) and chassis ground
Voltage
Max. 5 V
6
Defective work equip-
ment and pump
controller
a
If causes 1 – 5 are not detected, work equipment and pump controller
may be defective. (Since trouble is in system, troubleshooting cannot
be carried out.)
