PA Industries Edge Servo Roll Feed SRF-100(for Serial Numbers 7610697 and higher) - Manual (Page 13)

7. MAINTENANCE
The Edge Servo Roll Feed needs very little
maintenance to keep the system operating at its
optimum performance.
• This precision equipment must be kept as clean
as possible. This is especially important if large
amounts of air suspended oil mists in combination
with “dirty metals” are used. The resulting abrasive
dust can attach itself to the feed rolls and other
surfaces, leading to premature wear on many
parts.
• The roll release system requires clean, dry
air supply.
• Some bearings used on the feeder are fully sealed
and maintenance-free roller ball bearings. The
exceptions are provided with standard “zerk” type
grease fittings. They should be lubricated with a
good grade of high pressure bearing grease. The
frequency of lubrication will depend on the overall
usage of the system. A small “shot” once a day is
a good starting point. The cluster gear set should
be coated with a small amount of open gear grease.

LED Label LED Color Description
LOGIC P/S Green • ‘OFF’ = No incoming AC (Alternating Current) or if AC is present then
drive has internal power supply failure.
• ‘ON’ = Power is present
• During ‘POWER DOWN’, LED should turn off within approximately
1 second If not, shunt regulator is not functioning. Replace Drive.
1,2,3 Red • ‘OFF’ = No Fault
1 Red • ‘ON’ = Motor Over Temperature. If motor not hot, check
cables, connections
2 Red • ‘ON’ = Short circuit Over Current or excessive Average Current.
Check cables, binding, loose belt, parameters, motor connections.
3 Red • ‘ON’ = Bus Over Voltage
1,2 Red • ‘ON’ = AC line loss
• Power circuit not providing adequate volts/amps
• Electrical noise on 120 VAC supply
2,3 Red • ‘ON’ = Drive Over Temperature. Check Amplifier for excessive heat,
hot enclosure
1,3 Red • ‘ON’ = Logic Supply Fault. Check fuses in Servo Amplifier
6.2 DRIVE MODULE DIAGNOSTICS
Use the following table for Drive Module Diagnostics.
NOTE:
While the reset is engaged LED’s #2,3,4,will remain on and LED #1 will remain off.
