The Digisolver is a Rotary
Sensor which provides the Programmable Logic Controller (PLC) with a 0
to 359 degree value. The unit
operates on 24 VDC plus or minus 1.0 VDC and is connected with one of
the following cable lengths (part number): 50 ft
(113815); 60 ft (114014); 75 ft (114015): 100 ft (115114) or
150 ft (114182), between the Digisolver and input module 1:3. The word value
may be monitored by using the ROTARY SENSOR screen.
1. Make sure the coupler
connecting the Rotary Sensor shaft to your machine is making proper
connection to the prospective shaft.
2. Make sure that the ms
connector on the cable is screwed all the way into the mating ms
connector on the Rotary Sensor.
3. Check continuity on the
Rotary Sensor cable to verify that Pin A on the connector is making
continuity to the black wire at the other end of the cable. Next check Pin
B to white, C to grey, etc.
until complete. If the wire does not check out properly, repair or replace
cable.
4. Check to make sure that the
shield on the cable is tied to earth ground, and that one of the screws
on the mating ms connector on the Rotary Sensor is tied to the same
earth ground.
5. Check the resistance from the
Black/12 Gauge wire to earth ground. You must be reading at
least 100K Ohms or you will get an erratic reading from the Rotary Sensor.
If you are not getting this reading, make
sure that Black/12 Gauge wire is not tied to earth ground. This wire should
be connected to the common for the power supply and the signal common.
6. Check the voltage from the
White/12 Gauge wire to the Black/12 Gauge wire. You should be
reading +24, plus or minus 1.0 VDC E7B-B0360-8P0FS (Besser Part Number
454125). If not, check the power supply.
Check the voltage from the
White/Green wire to the Black/12 Gauge wire. You must be reading the
supply VCC voltage level. If not, check out the supply power source that is
powering the outputs.
NOTE: 1
This equipment uses isolated signal
common. Failure to assure at least 100K Ohms resistance between signal,
common, and earth ground may cause erratic output
data.
NOTE: 2
The shield drain wire should be
connected to earth ground at one end of the cable.
Make this connection at the panel side of the cable.
NOTE: 3
DO NOT connect Pin-P (White/Red) if the Digisolver is used. This unit has a
switch on the back for direction selection.
SAFETY BULLETIN
This notice is issued to advise you that some previously
accepted shop practices may not be keeping up with
changing Federal and State Safety and Health Standards. Your current shop
practices may not emphasize the need for
proper precautions to insure safe operation and use of machines, tools,
automatic loaders and allied equipment
and/or warn against the use of certain solvents or other cleaning substances
that are now considered unsafe or prohibited by
law. Since many shop practices may not reflect current safety
practice and procedures, particularly with regard to the safe operation of
equipment, it is important that you
review your practices to ensure compliance with Federal and State Safety and
Health Standards.
IMPORTANT
The operation of any machine or power-operated device can
be extremely hazardous unless proper safety precautions
are strictly observed. Observe the following safety precautions:
Always be sure proper
guarding is in place for all pinch, catch, shear, crush and nip points.
Always be sure that
all personnel are clear of the equipment before starting it.
Always be sure the
equipment is properly grounded.
Always turn the main
electrical panel off and lock it out in accordance with published lockout/
tagout procedures prior to making adjustments,
repairs, and maintenance.
Always wear
appropriate protective equipment such as safety glasses, safety shoes,
hearing protection and hard hats.
Always keep chemical
and flammable material away from electrical or operating equipment.
Always maintain a
safe work area that is free from slipping and tripping hazards.
Always be sure
appropriate safety devices are used when providing maintenance and repairs
to all equipment.
Never exceed the
rated capacity of a machine or tool.
Never modify
machinery in any way without prior written approval of the Besser
Engineering Department.
Never operate
equipment unless proper maintenance has been regularly performed.
Never operate any
equipment if unusual or excessive noise or vibration occurs.
Never operate any
equipment while any part of the body is in the proximity of potentially
hazardous areas.
Never use any toxic
flammable substance as a solvent cleaner.
Never allow the
operation or repair of equipment by untrained personnel.
Never climb or stand
on equipment when it is in operation.
It is important that you review
Federal and State Safety and Health Standards on a continual basis. All
shop supervisors, maintenance personnel, machine
operators, tool operators, and any other person involved
in the setup, operation, maintenance, repair or adjustment of Besser-built
equipment should read and understand this
bulletin and Federal and State Safety and Health Standards on which this
bulletin is based. |
