these adjustment procedures.
1. Re-install the ITB. (Field Service Manual > ITB Unit > Belt Replacement > Belt Re-installation)
2. Open SP2-310-002 (Force Apply Lubricant Operation Time Setting), and then change the setting
from 300 to 100 sec.
3. Open SP2-920-013 (Steering Control Roller Timeout of Belt Ready), and then change the setting
from 400 to 105 sec.
The timing settings for these SP codes must be shortened from their normal operation
settings in order to allow diligent operation checks.
Reducing SP2-310-002 to 100 sec. allows the machine to apply lubricant at 100 sec.
intervals, confirm that the position of the belt is stable, and then adjust the belt to the
positions of the left and right scale plates.
Depending on the conditions of the machine, after application of the lubricant ends the
belt may not be adjusted to its correct position within the target range within 100 sec. This
can occur if the belt has been re-installed out of position. In this case after the SP
executes lubricant application for 10 sec. and stops, the machine is not able to do the
correction quickly enough, so beforehand the belt ready SP2-920-013 timeout setting is
set to 105 sec. If the machine cannot correct the belt position within 105 sec. the machine
issues SC471-01 (Belt Position Ready Timeout), and SP2-310-002 (applying the
lubricant) stops, and then starts the process again after the belt has been steered to the
correct position.
4. Set the following steering control SP codes to “0”.
SP 2-920-002 (Steering Control Roller Stable Position of Steering Roller)
SP 2-920-004 (Steering Control Roller Last Time Ai Value)
5. SP 2-310-001 (Force Apply Lubricant Belt Cleaning) – 1st Execution
SP2-310-001 executes (100 sec.) After the SP executes, check the value of SP2-920-002
(Steering Control Roller Stable Position of Steering Roller).
If the value is -20 ≤ SP Value ≤ +20, do the next 2nd SP execution. At this time the SP value in
Step 4 is not set to “0”.
If the SP value is <-20 or >+20, then the “Steering Plate Adjustment” described below is
required. After this adjustment, set the value for the Step 4 SP to “0”, and then do the 2nd SP
execution.
6. Do SP2-310-001 – 2nd Execution
Do SP2-310-001 (100 sec.). After this SP executes, check the value of SP2-920-002 (Steering
Control Roller Stable Position of Steering Roller)
If the value is -20 ≤ SP Value ≤ +20, do the next 3rd SP execution. At this time the SP value in
Step 4 is not set to “0”.
If the SP value is <-20 or >+20, then the “Steering Plate Adjustment” described below is
required. After this adjustment, set the value for the Step 4 SP to “0”, and then do the 3rd SP
