Solution
71 ESTOP
Circuit
15 ESTOP
Return
circuit
shorted to
GND
Mistmatched
signals detected
on ESTOP
Return circuits.
Either:
* PCON ESTOP
2 and ESTOP
4 do not match,
or
* TCON ESTOP
2 and ESTOP
4 do not match.
ESTOP
circuit cannot
complete,
preventing
machine
functions.
* Inspect PCON J15 pins 11 and 12 for
open or short circuits. Using a voltmeter,
set to diode test mode and make sure the
diode tests ok with the anode at pin
12 and cathode at pin 11. If test fails,
replace the PCON.
* Inspect TCON J5 pins 11 and 12 for
open or short circuits. Using a voltmeter,
set to diode test mode and make sure the
diode tests ok with the anode at pin
12 and cathode at pin 11. If test fails,
replace the PCON.
* Check P23RET (BK) for shorts to
ground or power.
16 ESTOP
Power
circuit
shorted to
GND
TCON detected
that P56PWR is
shorted to GND,
thereby
preventing the
ESTOP circuit
from functioning.
Check P56PWR (RD, TCON J5-7) for
open or short circuits. Verify power is
reaching the P1 ESTOP contact block.
When ESTOP is pulled out, verify power
is reaching the KS1 keyswitch contact
blocks.
21 ESTOP
Return
circuit
mismatch
TCON detected
that ESTOP
Return circuits
are not matching,
indicating a fault
with either
P23PWR or
P23RET.
* Check for open and short circuits in the
boom cable.
* Verify that there is low resistance (less
than five ohms) on the cabling between
TCON J5-11 and PCON J15-11 (BK wire
in harness and boom cable). An open
circuit between these pins indicates a
harness or cable fault.
* Verify that there is low resistance (less
than five ohms) on the cabling between
TCON J5-10 and PCON J15-10 (RD wire
in harness and boom cable). An open
circuit between these pins indicates a
harness or cable fault.
22 ESTOP
Source
circuit is
shorted to
GND
TCON detected
that ESTOP 1 is
at 12 V but
ESTOP 3 is at 0
V.
* Using a voltmeter and with the system
turned OFF, check the resistance
between TCON J5 pins 9 and 10.
Replace TCON if resistance is more than
5 ohms.
* Check P79PWR (BK, TCON J5-9) and
P23PWR (RD, TCON J5-10) for open or
short circuits.
31 ESTOP
Source
circuit
mismatch
TCON detected
that ESTOP 1 is
at 0 V but
ESTOP 3 is at 12
V.
