SECTION 1: General Information

The Industrial Motion Control (IMC) Paradex Drives engineered and manufactured to very high
tolerances which necessitate careful inspection and maintenance.

Some users of indexing drives have the facilities and trained personnel to accomplish service repair.
You must determine the extent to which intricate servicing should be done in your own facility. When in
doubt, IMC recommends that IMC trained servicemen make the repairs.

1.1. Warranty - Products are warranted as follows:

1.1.1. Our products are warranted for one (1) year from the date of shipment to be free
from defects in workmanship and materials. The foregoing warranty is exclusive
and in lieu of all other warranties, whether written or orally expressed or implied
and there are no warranties of merchantability or fitness for particular use.

1.1.2. Our obligation under the foregoing is limited to replace free of charge, including the
lowest transportation cost, but not including installation or any other charges, any
part that our inspection shows to be defective provided that the part was properly
installed, suitably maintained and not subject to misuse or abuse, and further
provided that the defective parts are returned to our plant within one (1) year after
delivery by us. Written permission for such return must first be obtained from IMC.
A complete explanation is required of the alleged defects and circumstances.

1.2. Safety – Read and follow all Warnings and Cautions prior to any service or repair.

1.2.1. 1.2.1. Indexing Drives should not be started and stopped at high speed during the
transfer phase of the cams. This can cause serious damage to the Indexer and
reduce the cam follower life. For cycling during setup or jog mode, speed must
be reduced to 25% of the normal operating speed. The use of an E-stop for
purposes other than emergencies is not recommended. A cycle stop button
should be incorporated into the system controls. Please consult Industrial Motion
Control’s Wheeling factory for additional information.

1.2.2. Always disconnect power and lockout the source before working on these units.

1.2.3. All input and output connections should be backlash free. Use friction lock type
shaft couplings such as taper lock bushings, split and clamped hubs, etc., in the
input and output drive train. There should be no loose keys, set screws, etc., as
this may cause sheared keys and shaft damage.

3

SECTION 1: General Information (continued)

1.2.4. Reducers should be of minimum backlash variety and directly coupled with a
backlash-free connection. If line shafts are used, they must be sized for severe
reversing loads.

1.2.5. When using chain or belt drives, incorporate an idler to eliminate any slack. (Do
not use spring-loaded idlers.) As the cam motion stops and starts, any slack in
the drive changes sides. It is necessary to maintain a constant speed of the input
shaft. Loose V-belts or chains will cause inertial over-run, causing distorted
acceleration and deceleration characteristics which may cause damage to the unit.
Belts and chains must be sized for severe reversing loads.

1.2.6. Ferguson does not provide guarding for other moving parts, such as pulleys,
handwheels, switch cams, etc. Numerous pinch points do exist on this equipment
and the possibility exists of being struck by a moving part. Since this product is
expected to become part of a further developed machine, it is the customer’s
responsibility to add safety fencing, guarding, light curtains or other protection
devices, as necessary, to protect personnel and property.

NOTE: In the event the unit is damaged, contact Industrial Motion Control’s
Wheeling factory or your local representative, for proper reconditioning or
repair (see sections 1.5 Requesting Service or 1.6 Returning a Unit for
Repair).

1.3. Operating Environment – This machine is intended to operate in a clean environment.

Excessive coolant, chips, dust dirt or debris can adversely affect its performance and life.
If this machine does operate in a dirty environment periodic cleaning must be practiced
and careful inspection of seals and accessories is necessary.

1.3.1. For extended storage, remove vents and fill with proper oil. (Refer to section 6)

1.4. Ordering Replacement Parts – When ordering parts, always provide the following

information:

1.4.1. The serial number shown on the nameplate.

1.4.2. The part name and/or the description listed in the manual.

1.4.3. The part numbers shown on the bill of material or assembly drawings.

SECTION 1: General Information (continued)

1.5. Requesting Service – Call our Technical Service Department in Wheeling, IL at

1-800-645-5207 or 847-459-5200 between 8:00AM and 4:00PM CST. When requesting
service, always provide the following information:

1.5.1. The serial number shown on the nameplate. (Refer to Inside Front Cover)

1.5.2. A clear description of the problem, including as much detail as possible of the
circumstances leading up to the problem.

1.6. Returning a Unit for Repair – Please contact the Repair Department in Wheeling,

Illinois at [phone] for a "Return Material Authorization" Number (RMA#).

The following information is required of a unit for repair, conversion or warranty.

1. Purchase order number

2. Customer name

3. Customer billing address

4. Customer shipping address

5. Person to contact, upon inspection, with delivery and price.

6. Telephone number

7. Model number (located on name plate)

8. Serial number (located on name plate)

9. Description of defects, problems or circumstances.

The IMC Repair Department will assess repairs by phone and estimate inspection fees or
repair costs.

Non-warranty inspection fees will vary depending on the size of the unit and optional
equipment mounted. These fees apply only if customer decides not to repair or replace
subject unit.

Please return IMC equipment only (remove sprockets, pulleys, etc). This will reduce the
amount of disassembly time (saving customer cost on labor) and will provide faster
evaluation for quoting price and delivery of repair or conversion. Oil must be drained
before shipping.

Package unit to protect it from weather or damage during shipping. Place the
(RMA#) on the outside of the packaging for prompt service.

SECTION 4: Installation

These units are manufactured to meet a specific set of design parameters. Any change to the load on
the output shaft, or speed of the camshaft may require a size change. No change can be made without
affecting other performance characteristics of the unit and, therefore, should not be done without
consulting the factory.

4.1. To install the unit:

4.1.1. Rotate camshaft so cam is in center of dwell (see Figure 3).

4.1.2. Mount the Indexer into position on a rigid base and secure with the proper size
fastener.

4.1.3. Align the Indexer with respect to the station positions before tightening fasteners.
Use a dial indicator or other appropriate tools to insure alignment.

4.1.4. Tighten all mounting bolts securely and uniformly.

FIGURE 3

9

SECTION 4: Installation (continued)

4.1.5. Check the oil level of the sump and gear reducer prior to operating the unit.

4.1.6. Pay particular attention if the oil level is too high. If a unit has been idle for some
time since its manufacture, condensation may be present. If condensation is
noticed, the oil should be drained, the unit thoroughly cleaned and re-filled with
oil (see Chart 1 in Section 3 for capacities).

NOTE: If shot pins or guide pins in dies are used, the unit should have been
manufactured with a dwell relief in the cam. Tangential loads may require
the use of a shot pin or dial clamp. If vertical loads exist, an anvil may be
required. For further information, consult your Industrial Motion Control
Representative or the Technical Sales Department at 1-800-645-5207 or
847-459-5200.

4.1.7. The unit’s sump must be filled with SAE 90 EP Gear oil or equivalent meeting
MIL-PRF-2105E and API Service Classification GL5 or GL6 before operation
(see Chart 1 in Section 3 for capacities). An example of this oil is Mobilube HD
80W-90. For extreme applications, use Mobilube HD 85W-140 (consult your local
representative to determine if your application is extreme).

4.1.8. Bronze Gear Reducer oil must be SAE140 Steam Cylinder Oil meeting AGMA #8
Compound, MIL SPEC, MIL-L-15016A; symbol 3150 (see Chart 1 in Section 3 for
capacities). (Or manufacturer’s specified oil if not a Ferguson manufactured
reducer.)

4.1.9. Be sure optional controller is properly fused – refer to vendor’s manual, which is
included under separate cover for information on installation, set up, adjustment
and maintenance.

4.1.10. Check the adjustment of the Switch cam if your unit has this option. To insure
unit stops in dwell, see Figure 3.

4.1.10.1. A standard Parallel Shaft indexer is shown in Figure 3 with a Brake Cam

& Limit Switch shown with the keyway in the center of the dwell period.
It is necessary to phase the Brake Cam such that the input shaft of the
indexer stops during the dwell period of the index cycle while leaving
enough of the dwell period for the input shaft to accelerate to full speed
before leaving the dwell period.

10

SECTION 4: Installation (continued)

4.1.10.2. If the indexer has a drive code which causes multiple indexes per
camshaft revolution (i.e. X2, X3, etc… drive codes), additional lobe(s) on
the Brake Cam are required. The lobes will be equally spaced.
Therefore, phasing the one lobe of the Brake Cam to one dwell period
on the indexing cam will, in most cases, cause the other lobes to be
correctly phased with the other dwell periods.

NOTE: Controllers are normally shipped loose and brake cam / limit
switches are mounted to the unit. However, neither are set or
adjusted at the factory. Controller must be set for load & speed of
the application per instruction in the vendor’s manual. The limit
switch and brake cam must be set so as to initiate the stopping
cycle and result in an on station stop (somewhere in the cam’s
dwell period).

NOTE: The switch and brake cam commonly provided to initiate
the stop cycle can not be used to indicate “on station.” A second
switch and brake cam should be ordered for this purpose.

11

SECTION 5: Adjustments

The ParaDex is a solid mechanical, backlash-free mechanism. There are no adjustments required on the
Indexer during installation unless it is furnished with a torque limiting device or a motor drive package
equipped with speed control. After the Indexer has been installed and set up with the users’ load in place
it will be necessary to check these items for proper adjustment & settings.

5.1 Typical Output Shaft Torque Limiter

FIGURE 4

12

SECTION 5: Adjustments (continued)

5.1.1. To adjust trip torque, remove locking setscrew. Use spanner wrench to adjust nut
position. Turn clockwise to increase torque or counterclockwise to decrease.
See Chart 2 for torque adjustment values.

5.1.2. Replace locking set screw after achieving required torque.

NOTE: 1) Total torque range in the different models is achieved by a combination of

different spring groups and applied pressure through the adjusting nut.
Chart 2 below shows the different torque ranges available for each spring group.
When reordering specify model number (e.g. RT3-6001, etc.) for your required
spring range.

2) If a tamper proof setting is desired, apply a permanent adhesive, such as
Loctite®680, to the setscrew after achieving the required trip torque value.

SECTION 5: Adjustments (continued)

5.2.1. Clutch Adjustment Description
The clutch must be adjusted to prevent any slippage during normal operation to
prevent shock loading. It should also not be adjusted so tight as to be able to
damage the indexer during a jam or overload. However, it is best to err on the side
of being tighter than required. The proper setting for the clutch is determined by
gradually tightening the clutch adjusting nut until the clutch no longer slips in either
direction during a complete, fully loaded index cycle at normal speed.

5.2.2. Shut-off Spool Use & Adjustment
The shut-off spool (number 8, Figure 5) is attached to body and cone (number 3,
Figure 5) by means of shallow round threads in body and cone (number 3,
Figure 5) and a ball plunger (number 9, Figure 5) in spool (number 8, Figure 5).
When the clutch is operating normally (i.e. not slipping), there is no relative
movement between spool (number 8, Figure 5) and main body (number 3, Figure

5) and the remainder of the clutch, including the spool (number 8, Figure 5) driven
by pin (number 7, Figure 5). This relative rotation causes the spool to move along
the screw threads on the body (number 3, Figure 5). The spool will move to the
left or to the right, depending on the rotation of the clutch. This lateral movement
of the spool is intended to activate a limit switch arm located in the center groove
in the spool. The "tripped" limit switch should be electrically connected to the
controls to stop the operation of the motor driving the indexer.

To recover from a jam or overload in which the clutch has slipped sufficiently to
displace the shut-off spool:

Manually disconnect the power to the drive motor to prevent an accidental
start-up (use O.S.H.A. approved lockout procedures), clear the cause for the
overload. Then simply push or pull the spool (number 8, Figure 5) on the main
body (number 3, Figure 5) to the thread engagement which is closest to the center
position on the threaded portion of the body (number 3, Figure 5). Check the limit
switch circuitry for proper operating conditions. The indexer can now be powered
up and production resumed.

15

SECTION 5: Adjustments (continued)

5.2.3. Clutch Adjustment Procedure

CAUTION: OPERATIING THE INDEXER WITH THE CLUTCH NOT ADJUSTED
CAN CAUSE IMMEDIATE AND SEVERE DAMAGE TO THE INTERNAL
COMPONENTS OF THE INDEXER.

a. Loosen cone point setscrew (number 11, Figure 5).
b. Insert pins of spanner (Figure 6) into holes of adjusting nut (number 6,

Figure 5), and turn nut clockwise one notch in the adjusting nut. This will
tighten the clutch.

NOTE: For heavy indexing loads or clutches on large units, it may be
necessary to increase the length of the spanner wrench to gain more leverage.

If clutch has not been adjusted for a long period of time, it may be necessary
to turn the nut counter-clockwise several turns, and tap the face of housing
(number 1, Figure 5) towards the indexer with a rubber mallet to separate
(loosen) the tapers. Take note of the number of loosening turns so the
adjusting nut can be re-tightened to its original position.

c. Re-tighten setscrew (number 11, Figure 5) making sure it engages in adjusting

nut (number 6, Figure 5) to prevent damage to screw threads.

NOTE: If setscrew (number 11, Figure 5) is accidentally tightened on
threaded portion of adjusting nut (number 6, Figure 5), it will raise a burr.
Failure to remove this burr will cause shearing of threads and jamming of nut
of housing (number 1, Figure 5). To remove burr, remove setscrew (number 11,
Figure 5) and rotate adjusting nut counter-clockwise until burr is in center of
tapped hole in housing (number 1, Figure 5). Use a hand electric drill that fits
freely into the tapped hole. Drill into the adjusting nut (number 6, Figure 5)
sufficiently to remove the burr.

There are (2) setscrews (number 11, Figure 5). They are positioned so one
screw is half way between the slots in the nut when the other screw engages
the slot in the nut. This is to allow for fine adjustment of the clutch. DO NOT
use both screws at the same time as one screw will not be over a slot and will
cause damage to the screw threads.

FIGURE 6

16

SECTION 5: Adjustments (continued)

d. Apply power to the unit and check for clutch slippage.

NOTE: When clutch is not slipping, entire clutch will rotate as a single unit.
When clutch is slipping body and cone (number 3, Figure 5) will not rotate with
the other parts of the clutch. Small amounts of clutch slippage can be difficult
to determine. To aid in providing if the clutch is slipping, use a grease pencil
or felt tip marker and draw a line across face of nut (number 6, Figure 5) and
along body and cone (number 3, Figure 5). If clutch is slipping, the line on nut
(number 6, Figure 5) and body and cone (number 3, Figure 5) will move
relative to each other.

DO NOT LET CLUTCH SLIP ANY LONGER THAN NECESSARY OR
CLUTCH MAY HEAT UP RESULTING IN UNPREDICTABLE OPERATION
AFTER IT COOLS.

e. Repeat steps a through d until there is positively no clutch slippage.

5.2.4. Lubrication:
a. Clutches are grease packed at the factory and should not require additional

lubrication. If clutch is subject to consistent slippage and heating, remove pipe
plug (number 9, Figure 5) and insert your standard grease fitting, lubricate with
Lithium EP grease. Do not use air pressure gun!

SECTION 6: Maintenance

6.1. Correct Lubricants – For the protection of the unit use only lubricants meeting the

specifications shown below in Chart 3. If you have any questions about a particular
lubricant feel free to call us at 1-800-645-5207 or 847-459-5200.

6.2. Changing Oil

6.2.1. All parts are oil splash lubricated except for isolated areas where grease fittings
will be supplied.

6.2.2. Maintain oil to the midpoint of the sight gauge or oil level & fill plug.

NOTE: The orientation of your unit will determine the exact quantity of oil
required.

6.2.3. Drain, flush and fill the unit in intervals of 2400 hours or at least yearly. If drive
operates at speeds above 300 RPM or at temperatures above 140 degrees F.,
increase oil change frequency to 6 months or 1200 hour intervals.

NOTE: When draining the oil observe for metal particles. This is an indication
of excessive wear and the source of this wear must be determined.

6.2.4. Service all grease fittings on 1-month intervals or every 200 hours of operation.

NOTE: In the majority of the applications, grease fittings are not supplied
since oil splash supplies the lubrication. Should grease be specified use
Lithium No.2.

Indexer Oil: Use SAE 90 EP Gear oil or equivalent meeting MIL-PRF-2105E and

API Service Classification GL5 or GL6. For example, Mobilube HD 80W-90

Capacity: See specifications in Chart 1 for your model.

Gear Oil: Bronze Gear Reducer oil requires SAE 140 Steam Cylinder Oil,

meeting AGMA #8 Compound, MIL SPEC. MIL-L-15016A; symbol 3150
(Or manufacturer’s specified oil if not a Industrial Motion Control
manufactured reducer.)

Capacity: See specifications in Chart 1 for your model.

SECTION 8: Repair and Replace (continued)

8.3. Oil Seal Replacement

8.3.1. Remove oil seals by drilling a number of holes into the case. The seal may then be
removed with a pointed tool. Be sure to remove all metallic chips created during
the drilling of removal holes.

8.3.2. Check dimensions – to be sure that shaft and bore diameters match those
specified for the seal selected.

8.3.3. Check seal – for damage that may have occurred prior to installation. A sealing lip
that is turned back, cut or otherwise damaged should be replaced.

8.3.4. Check bore – to see that the leading edge is deburred, a rounded corner or
chamfer should be provided.

8.3.5. Check shaft – remove surface nicks, burrs and grooves and look for spiral machine
marks that can damage the seal lip.

8.3.6. Check shaft end – remove burrs or sharp edges. The shaft end should be
chamfered.

8.3.7. Check splines and keyways – smooth any sharp edges and when necessary
protect the seal lip with an assembly sleeve or shim stock. Round the edges of the
spline or keyway as much as possible and lubricate with a hard, fibrous grease.

8.3.8. Check seal direction – make sure that the new seal faces in the same direction as
the original. Generally, the lip faces the lubricant or fluid to be sealed.

8.3.9. Pre-lubricate the sealing element before installation by wiping with lubricant
being retained.

8.3.10. Use the correct installation tool – press fitting tools should have an outside
diameter .010” smaller than the bore size. If possible, the center of tool should be
relieved so that pressure is applied only at the O.D.

8.3.11. Use proper driving force – where possible, an arbor press; otherwise, a dead blow
hammer to avoid popping the spring out of the seal. NEVER HAMMER DIRECTLY
ON THE SURFACE OF THE SEAL.

23

SECTION 8: Repair and Replace (continued)

8.3.12. Bottom out the tool or seal – to avoid cocking of the seal in the bore. This also
positions the seal correctly on the shaft.

8.3.13. Check for parts interference – from other machine parts that might rub against the
seal causing friction and damaging heat.

8.4. Reducers

SECTION 8: Repair and Replace (continued)

8.4.1. “R” Series (Ferguson) Reducers

NOTE: The “R” Series reducer is a double enveloping worm gear type
with components manufactured to Industrial Motion Control’s specifications
by selected vendors. The worm and gear are provided in matched sets
with minimal backlash and installed in housings of Industrial Motion
Control’s design.

The identifying number of a reducer consists of the letter “R” followed by a
number and a two-digit number (i.e. R4 15). The “4” indicates the center-to­center distance between the worm and the gear; the “15” reflects the
reduction ratio. In this example, the ratio is 15:1.

8.4.1.1. Component Removal

8.4.1.1.1. Worm Shaft.

8.4.1.1.1.1. Drain oil and remove cover plate.

8.4.1.1.1.2. Record the distance between the worm bearing shoulder
on the splined end of the shaft (opposite the single
extension end of the shaft) to the finished bore on the
cover side (see Figure 8).

8.4.1.1.1.3. Remove screws and worm bearing caps, keeping each set
of shims with their respective bearing caps.

8.4.1.1.1.4. Tap the worm shaft back and forth axially to move the outer
race of the supporting bearings out of position.

8.4.1.1.1.5. Shaft the worm to the side of the housing, clear of the
gear. Remove the worm through the bearing bore in the
housing.

25

SECTION 8: Repair and Replace (continued)

NOTE: Worm must be dropped down before attempting to remove the gear.

8.3.1.1.2. Gear

8.4.1.1.2.1. Remove the worm as described above.

8.4.1.1.2.2. Record the distance from the finished face of the housing
to the unmarked face of the gear (see Figure 8).

8.4.1.1.2.3. Remove screw and washer retaining gear, if applicable.

8.4.1.1.2.4. Loosen the screw clamp on the split hub side of the gear.

8.4.1.1.2.5. Remove the gear. Tapped holes in the end of the gear hub
may be utilized in conjunction with a puller.

8.4.1.1.3. Component Replacement

NOTE: If both worm and gear were removed from the housing,
the gear must be replaced before the worm shaft is installed

8.4.1.1.3.1. The correct relationship of the worm and gear must be
maintained when reassembling the components. Regardless
of the actual position of the reducer unit on the roller gear
drive or Intermittor housing, you must imagine that the worm
is over the gear and that you are viewing the worm from the
single extension end (the end opposite of the splines on the
worm shaft) with the unmarked face of the gear to your right.
Maintain this relationship between components when
installing the gear on the roller gear camshaft.

26

SECTION 8: Repair and Replace (continued)

8.4.1.1.3.2. The distance from the finished face of the housing to the
unmarked face of the gear, noted at the time of
disassembly, must be duplicated, either by grinding the
adjusting spacer or adding shims (see Figure 8).

8.4.1.1.3.3. Tighten the clamp screw in the split hub of the gear and
assemble the gear retaining screw and washer, if such
were provided as part of the factory installation.

8.4.1.1.3.4. Press cones of the tapered bearings onto the worm shaft
and insert the worm shaft in the housing.

8.4.1.1.3.5. Assemble bearing cups, shims and caps and establish pre­load, 2 IN-LBS, .003 SHIM. Adjust shims under bearing
cups until the dimension between the worm bearing
shoulder and the finished housing bore, as recorded at the
time of disassembly, is duplicated (see Figure 8).

NOTE: Do not discard any of the shims. Make
adjustments in pre-load by shifting shims from one
bearing cup to the other.

8.4.1.1.3.6. Replace cover plate and refill with oil. Refer to Chart 1 & 3
for quantity and specification.

8.3.2. Winsmith Worm Gear Reducer

NOTE: Due to its modular and hollow shaft design, it is not considered
economical to replace components only in these reducers. Except for seal
or other oil leak problems, replacement of entire reducer is recommended.

8.3.3. Brison Gear Motor

NOTE: May come with 1/11 HP or 1/4 HP motor depending on reducer ratio.

It is not considered economical to repair or replace components only. Replacement
of the entire product is recommended.

SECTION 9: THINGS TO AVOID

An Industrial Motion Control Indexer is a relatively simple mechanism using an input shaft
mounted cam to drive roller followers on the output hub. While simple in concept, the precision
nature of the indexer requires that it must be used within design constraints. The indexer is, after
all, just a mechanical device. In this regard there are several situations which should be avoided
to protect your warranty and maximize indexer life.

Off-center loading, such as might be seen when a large press is used in

conjunction with an indexer, requires a back-up support anvil under the dial.
The bearings of an indexer are very heavy duty, but their life will be shortened
dramatically by unsupported, asymmetrical loading. The support anvil is typically
designed with .001” of clearance under the dial and is strong enough to carry the full
load of the asymmetrical load. Consult Industrial Motion Control Technical Sales
Department at 1-800-645-5207 or 847-459-5200 for assistance in all asymmetrical
load situations.

E-Stop Usage should be limited to emergency situations only. E-Stops should not
be used to jog an indexer. The E-Stop function causes extreme load conditions
inside the indexer by virtue of the instantaneous stopping of significant weights.
This is not unlike driving a car into a brick wall. Excessive use of the E-Stop will
significantly shorten the life of the indexer.

Starting and Stopping while in the motion profile of the cam will also put high
loading on the indexer’s internal components. Should it be necessary to stop/start
the indexer in any position other than the dwell of the cam, it is best to reduce motor
speed to avoid overloading the unit.

Shock Loading may also lead to problems. Shock loading typically occurs when
there is looseness in the input drive train or where the output load is not stable.
This condition will eventually damage either the indexer’s followers or cam.
Overload devices, that are not set correctly, are sometimes a source of this
condition. Chain drives or loose timing belt drives are also potentials.

Machine Jams, like E-Stops, put excessive loading on an indexer. While the impact
of jams is minimized by the use of overload devices, it is always best to track the
occurrence of jams and, when possible, rectify the condition that led to the jam.
A high jam frequency will shorten indexer life.

28

SECTION 9: THINGS TO AVOID (continued)

Friction from any source adds to the load of an indexer. This can include cam

driven mechanisms and/or additional, ancillary devices driven off the indexer’s drive
shaft or output. Extreme build-up of contamination or other sources of interference
adds to the frictional load. Industrial Motion Control indexers handle frictional loads
very well, but the loading must be evaluated in terms of the indexer’s overall
capacity to ensure that the life of the equipment will not be compromised.

IMPROPER LUBRICATION CAN RESULT IN IMMEDIATE CATASTROPHIC
FAILURE OF THE UNIT.

Contact Industrial Motion Control Technical Sales Department (1-800-645-5207 or 847-459-5200)
or your local Sales Engineer for assistance when evaluating the above conditions.
