Trouble shooting (continued)
Problem

Solution
16.7) Ram is shorted to
frame
16.7) Check to see if R3 or R6 are activated. If these are
activated and the upper tool is not touching lower tool, then
you must look for a short from the Ram To Frame. Typically
this will happen because of a loose guard or one that has
some metal showing at or near the top portion of the ram.
Note The ram must be completely isolated form the frame
except for tooling contact.
Hydraulic leak or
broken hose.
Ensure there are no hydraulic leaks at hose connections and
fittings. Also check to ensure there is enough hydraulic fluid
in the tank.
4 way valve sticking
Check to see if the light on the down solenoid is coming on
when the down footswitch is depressed. If the light is
coming on, manually activate the down solenoid and see if
the ram comes down. If the ram comes down then change
out the 4way valve. If the ram does not come down check
for other hydraulic problems.
Ram will not
go up
Top Of Stroke Setpoint
incorrect.
Check the Top Of Stroke set point on the Change PLC Values
screen. Should be at least 10 numbers below the current
value reading with the ram at full up position.
17.2) PLC not working
17.2.1) Check for output Y9 on the PLC to see if it is on. If
not check to see if X4 on the PLC is on when stepping on the
up pedal at the foot switch. If X4 does not come on check for
a shorted foot switch. If Y9 on the PLC does come on then go
to 17.2
K5 Relay burnt
Inspect Relay K5
Foot Switch shorted
Check the PLC input X5 is coming on when the up pedal is
depressed.
4 way up solenoid valve
not working.
Visually check the up solenoid valve on the 4way to see if it
lights up when the up pedal is pressed. If it does light up the
manually depress the 4way valve. If the ram goes up, change
out the 4 way valve. If there is no light on the up solenoid,
verify wiring and power going to up solenoid.
loose wire
Verify there is power at T-20 ( 24vdc) and then check for
power at Solenoid valve. If no power at valve but there is
power at T-20, check for a broken or loose wire.
Fastener will
not feed
MAS is empty.
Check to ensure there is enough fasteners in the MAS.
Fasteners are jammed
in orientation or
singulation modules.
Check the orientation module and the singulation module
to ensure that there are no fasteners jammed in either.
