body side, loosen upper fixing bolts(*5) and lower fixing bolts(*6). Then remove upper fixing bolts(*5) only.
To set interlocking pulley plates(*7) at inclined-angle of conveyor main body, turn them using interlocking
pulley(*8) shaft as rotation axis. Once angle adjustment is completed, fix interlocking pulley plates(*7) byretightening upper fixing bolts(*5) and lower fixing bolts(*6).
NOTE: 1. If endless belt is already installed to conveyor main body, remove interlocking pulley(*8) from belt
feeder unit. Put interlocking pulley(*8) inside belt, and then reinstall it to belt feeder unit.
2. When connecting belt feeder unit to conveyor main body horizontally, make sure that bothinterlocking plates(*1) are set horizontally.
● Before installation● Installation angle of interlocking plate- Conveyor for downward use only

- Conveyor for upward use onlyor for reversible use- Setting interlocking plate angle athalf of conveyor main body’s

2. Installing belt feeder unit to conveyor main bodyInsert both interlocking pulley plates(*7) into tail frame end of conveyor main body, and fix them with
attachment bolts and nuts(*9)(2 sets on each side).
NOTE: 1. If interlocking drive chain is not installed, install it to interlocking sprockets of conveyor main
body and belt feeder unit. When running conveyor, be sure to install chain cover.
2. In operation after setting up machine, if it is necessary to make material transfer smoother, besure to switch off power supply and loosen upper fixing bolts(*2, *5) and lower fixing bolts(*3,*6). Then set angles of interlocking plates(*1) at half of conveyor main body’s. (See the bottom
figure on p.19.) For proper material transfer condition, make further angle adjustment if
necessary. Once adjustment is completed, retighten upper fixing bolts(*2, *5) and lower fixing
bolts(*3, *6).
3. Apply oil to drive chain every 3 months or every 1,000 operating hours.
4. For belt feeder with intermediate take-up, similarly install it to conveyor main body.
● After installation (eg Conveyor for upward use only or for reversible use)

3-5. INSTALLING GUIDE RAILS OR GUARDRAILS (OPTIONAL)

RUNNING THE CONVEYOR

4-1. BEFORE TURNING ON START SWITCH
Before turning on start switch, be sure to check items below:
1. Loose/missing bolts or nuts:
may cause parts to come off conveyor or frame to be bent. Before operation, retighten bolts
and nuts. Supply spares if there are any missing ones.
2. Grounding:
To prevent electric shock, be sure to ground earth wire.
3. Damaged connectors or switch:
may cause electric leakage or motor to burn out due to overload etc. Replace them, if any.
4. Electrical wiring:
To prevent electric leakage or electric shock, make sure that there is no unshielded portionin electrical wiring.
5. Frame:
Confirm full length of frame is level on top, straight and not bent in any place. Incorrectframe condition may cause belt deviation or unexpected accidents.
6. Rotation malfunction of tail pulley or rollers:
may damage belt. Replace defective tail pulley or rollers, if any. Remove foreign substancessuch as strings, if any.
7. Belt slack:may cause belt to slip and reduce conveyor performance, and it may damage belt or pulleys.
Take up belt properly.

→ See “５ TAKING UP THE BELT”, p.23.

8. Inappropriate power source or voltage:
If not sure, contact appropriately qualified specialists.

CAUTION■ Emergency stop

4-2. AFTER TURNING ON START SWITCH
When the following problems occur after turning on start switch, perform as follows:
1. Belt does not run (Motor pulley does not rotate):
Turn off start switch and power supply immediately, or motor pulley may burn out.
Check electrical wiring and motor pulley. → Refer to “10 INSPECTION AND
MAINTENANCE”, p.41.
NOTE: For motor pulley with backstop, it does not run if electrical wiring is set to reverse
belt travel. In this case, correct electrical wiring.
2. Belt is running in wrong direction:
Turn off start switch. Disconnect male connector from female connector. Reconnect maleconnector to female connector upside-down.
3. Belt is not correctly aligned:
It may cause belt to become damaged or motor pulley to burn out due to overload.
Adjust belt alignment. → See “ ６ BELT ALIGNMENT ADJUSTMENT”, p.25.
4. Motor pulley or rollers make abnormal noise:Contact our local agent.
5. Belt speed is different from set speed:
It is possible that belt has jammed or become slack. Check and correct belt condition.
For other problems, refer to “10 INSPECTION AND MAINTENANCE” on p.41-45 or
contact our local agent.

CAUTION■ Do NOT touch the conveyor when it is running
There is considerable risk of being caught and injured by the conveyor.

■ Beware of entanglement
When working close to the conveyor, take care not to get caught in it.
There is a risk of unexpected injury.

S-CONⓇBT (BT and BTG models)For machines with tail take-up unit, move tail pulley(*2) together with take-up brackets(*3) outward by
turning right and left take-up screws(*1) clockwise with a spanner. Belt will then be taken up. When turning
take-up screws(*1), adjust them alternately, little by little, to keep their movement lengths the same.
● Tail take-up unit

5-2. TAKING UP BELT USING CENTER TAKE-UP UNIT
For S-CONⓇFLAT (BF, BFG and BFGS models)
1. Machine with vertical center take-up unit
Move take-up pulley(*5) by turning right and left take-up screws(*4) counterclockwise with a spanner. Belt
will then be taken up. When turning take-up screws(*4), adjust them alternately, little by little, to keep their
movement lengths the same.
● Vertical center take-up unit
(Take-up stroke: 100mm)

2. Machine with horizontal center take-up unit
Move take-up pulley(*7) by turning right and left take-up screws(*6) counterclockwise with a spanner. Belt
will then be taken up. When turning take-up screws(*6), adjust them alternately, little by little, to keep their
movement lengths the same.
● Horizontal center take-up unit
(Take-up stroke: 500mm)

233. Machine with double horizontal center take-up unit
First move either of take-up pulleys(*9 or *11) by turning right and left take-up screws(*8 or *10)
counterclockwise with a spanner. Next similarly move the other take-up pulley(*9 or *11) by turning rightand left take-up screws(*8 or *10) counterclockwise. Belt will then be taken up. When turning take-up
screws(*8 or *10), adjust them alternately, little by little, to keep their movement lengths the same.
● Double horizontal center take-up unit
(Take-up stroke:500＋500ｍｍ)■ Belt tension
Do not take up belt too much, but only to the extent that belt does not slip on motor pulley (drive pulley),i.e. enough to drive belt.
NOTE: Excessive belt take-up may overload motor or shorten service lives of belt and pulleys.

● Standard belt expansion percentage (when provided with standard belt)

NOTE:

How to measure belt expansion percentage (→ See figure below.)

Before taking up the belt, paste a piece of masking tape on the belt center. Then paste another piece ofmasking tape on the belt at distance of 1000mm. For example, take up the belt until the distance
between these 2 pieces of tape becomes 1003mm. The belt expansion percentage will then be 0.3%.
However this value is just standard, so keep in mind that it may vary depending on the situation.
NOTE:

After taking up the belt, if it is not properly aligned, adjust belt alignment. → See“６ BELTALIGNMENT ADJUSTMENT”, p.25.

BELT ALIGNMENT ADJUSTMENT

When belt is not properly aligned, check machine condition and adjust belt alignment as follows:

6-1. PRIOR CHECKING
1. Frame:
Confirm full length of frame is level on top, straight and not bent in any place. Particularly, carefully
check frame joints. → See figures below.
2. Foreign substances on pulleys and rollers:
Check each pulley and roller for foreign substances. If any, remove them and clean pulleys and rollers.
3. Foreign substances on belt undersurface:
Check belt undersurface for foreign substances. If any, remove them and clean belt undersurface.
4. Obstacles to belt:
Check belt for obstacles to its correct travel. If any, remove or relocate them.
5. Loading condition:
Improper loading, i.e. not-centered, may cause belt deviation.

6-2. BELT ALIGNMENT ADJUSTMENT
1. Checking belt deviation
Check how belt is deviating before adjusting alignment. Reset positions of parts below as instructed whilerunning conveyor slowly, and then continue running it for a while to check any further belt deviation.

(1)To slacken belt fully, move tail pulley(*2) inward by turning right and left take-up screws(*1).
(2)If covers are attached on conveyor undersurface, remove them all by loosening attachment bolts.
NOTE: For S-CONⓇBT (BT and BTG models) with head scraper, skirts or hopper in tail unit, remove
them by loosening attachment bolts.
(3)Remove head snub pulley(*3) together with attachment plates. Remove frame brace(*4) by loosening
attachment bolts.
NOTE: 1. If machine has snub pulley in tail unit or other frame braces on belt return side, remove themalso.
2. For geared motor driving type, see NOTE 1, p.34.
3. For machine with center take-up unit, see NOTE 2, p.34.
(4)Remove all the return rollers(*5) together with brackets by loosening attachment bolts on frame
undersurface.
(5)If machine has frame supports such as stands, to make a space to replace belt, remove their
attachment bolts only on one side and raise frame.
(6)Remove belt sideways and correctly install replacement endless belt.
NOTE: If it is impossible to insert belt into machine, remove tail pulley together with brackets. Reinstallthem in initial positions after inserting belt.
(7)Reinstall frame supports such as stands in initial positions.
(8)Reinstall parts removed in steps above (return roller, snub pulley, frame brace, lower cover, etc.) in initial
positions.
(9)Fit belt center to conveyor center. To take up belt slack, move tail pulley(*2) outward by turning takeup screws(*1).
NOTE: To make belt tension equal on both sides of conveyor, turn right and left take-up screws(*1)
alternately, little by little. → See “ ５ TAKING UP THE BELT”, p.24.

Taking Up Drive Chain
When drive chain is slackened off, take up drive chain as follows:
NOTE: Before starting procedures below, be sure to stop conveyor and switch off power supply.
Remove chain cover. Loosen attachment bolts and nuts(*2)(4 sets) of motor base(*1). Slightly movemotor base(*1) together with geared motor inward by turning adjustment bolt(*3) as shown in figureright. Drive chain will then be taken up. Make sure that drive chain looseness is proper. (→See “Standard
drive chain looseness” below.) Retighten attachment bolts and nuts(*2) and reinstall chain cover.
If belt deviates after taking up drive chain, adjust belt alignment. (→ See “６ BELT ALIGNMENTADJUSTMENT”, p.25.) When adjusting belt alignment, make sure that chain cover is installed.
● S-CON®FLAT (Head drive type BFG model)● S-CON®BT (BTG model)● Standard drive chain looseness (→See figure below.)Standard drive chain looseness (length between S and S’) is about 3 to 4 % of the span (length
between sprocket-centers).
If machine is provided with standard geared motor support, standard drive chain looseness is about 15 to
20mm.
Properly adjust drive chain looseness referring to these standard values.
