12 Travel Direction Change Counter

Note:
•
If o4-40 is active and you have not set a password, a TCS alarm [TDCC Setup Alarm] is present.
• During maintenance, log the values for U4-64 to U4-68 and o4-41 occasionally.
If a drive brakes and cannot be powered on anymore, these values cannot be restored. In such a case, a person responsible for elevator
safety must decide if ropes need to be replaced or if values can be estimated.
◆
Counter Reset
To reset the Travel Direction Change Counter (TDCC) after you replaced ropes, enter the limit of bending
changes to
TDCC Pres Value [o4-42] . The value entered is in thousands, e.g. when you enter
‘
1
’
it means 1000
direction changes are allowed.
When you entered the value, the monitors Rem Dir Chg [U4-65, U4-66] will be updated, and 04-42 will be reset
to 0 .
