fore opening!
Fault
Potential cause
Remedy
Vibratory feeder does
not start on power up
Mains connector of control unit not plugged-in
Connecting cabled between vibratory feeder
and control unit not plugged-in
Only in conjunction with controller
ESK 2000
Sensor erroneously indicates part accumula-
tion due to defect our misalignment
(green LED illuminated = vibratory feeder
'STOP')
Defective fuse in control unit
Power switch off
Plug in the mains connector
Plug 5-pin connector into control unit
Replace or re-adjust the sensor
Check if sensor is plugged-in
Replace fuse
Close power switch
Vibratory Feeders
vibrates only slightly
Controller set at 0 % on control unit
Wrong vibration frequency
Attention
If you operate a vibratory feeder designed
for 100 vibrations per second without hav-
ing inserted the jumper in the 5-pin con-
nector, there is a risk of damage to the
controller and magnet.
Set controller to 80 %
Check that coding in plug connector of the
controller is correct (see rating plate and
'Technical Data' (Section 1))
The vibratory feeder no
longer meets the re-
quested feeding ca-
pacity after prolonged
operation.
Screws of one or more spring packs have
come loose.
Broken springs
Misadjusted coil-to-armature gap
Fixing screws of feeder bowl have come
loose.
Tighten screws (for tightening torques see
'Technical Data' in Section 1).
Replace broken springs
Readjust the air gap (for gap size see
'Technical Data' in Section 1).
Re-tighten the screws
Vibratory feeder makes
loud noises
Fixing screws of enclosure have come loose.
Bowl bottom is jammed
Foreign matter in air gap
(chips, or dust, parts handled)
Only for SRHL 400 and SRC-N 800:
Locking screw on armature plate has come
loose
Re-tighten the screws
Eliminate the jam
Stop linear feeder and remove foreign mat-
ter. Then check the coil-to-armature gap.
Re-tighten the screw
Vibratory feeder cannot
be tuned to a constant
speed for longer peri-
ods of time.
The spring constant of the vibrating system
has changed. The vibratory feeder operates
close to the resonance point.
Re-tune the vibratory feeder. Remove
springs. See Section 5: Tuning
