Auto-Reset Delay; Secondary Motor Set - Danfoss mcd-500 Operating Instruction

7 Programming

7.10.1 Auto-Reset Delay

The MCD 500 can be configured to wait before auto-resetting a trip. Separate delays can be set for trips in Groups A and B, or in Group C.
6-3 Reset Dly Grp A & B
Range:
5 secs* [00:05 - 15:00 (min:secs)]
6-4 Reset Dly Grp C
Range:
5 min* [5 - 60 (minutes)]

7-6 Start Ramp Time-2
Range:
10 secs* [1 - 180 secs]
7-7 Kickstart Level-2
Range:
500%* [100% - 700% FLC]
7-8 Kickstart Time-2
Range:
0000 [0 - 2000 msecs]
msecs*
70
Function:
Sets the auto-reset delay for Group A and Group B trips.
Function:
Sets the auto-reset delay for Group C trips.
Function:
Matches the starter to the second motor's full load current. Set to the full load current (FLC) rating
shown on the motor nameplate.
Function:
Sets the maximum length of the time the motor can run at locked rotor current from cold before
reaching its maximum temperature. Set according to the motor datasheet.
If this information is not available, we recommend the value should be less than 20 seconds.
Function:
Selects the start mode for the secondary motor.
Function:
Sets the current limit for constant current and current ramp soft starting, as a percentage of motor
full load current.
Function:
Sets the initial start current level for current ramp starting, as a percentage of motor full load current.
Set so that the motor begins to accelerate immediately after a start is initiated.
If current ramp starting is not required, set the initial current equal to the current limit.
Function:
Sets the total start time for an AAC Adaptive Control start or the ramp time for current ramp starting
(from the initial current to the current limit).
Function:
Sets the level of the kickstart current.
Function:
Sets the kickstart duration. A setting of 0 disables kickstart.
