Trip Codes
| Ready | Description |
|---|---|
| x1 | Power Circuit: Check mains supply L1, L2, L3; motor circuit T1, T2, T3; |
and soft starter SCRs.
x6| Supply Frequency: Check supply frequency is in range.
x8| Network Communication Failure (between accessory module and network):
Check network connections and settings.
x9| Starter Communication Failure (betwen starter and accessory module):
Remove and refit accessory module.
Disconnect from the power source before installing or servicing.
Always apply control voltage before (or with) mains voltage.
With 24 VAC/VDC use contacts rated for low voltage and low current (gold flash
or similar).
This product has been designed for Class A environments. Use of this product
in domestic environments may cause radio interference.
High Voltage Warning
The MCD 203 contains dangerous voltages when connected to line voltage. Only a competent electrician should carry out the electrical installation. Improper installation of the motor or the MCD 203 may cause equipment failure, serious injury or death. Follow this manual, National Electrical Codes (NEC®) and local safety codes.
Safety Regulations
The soft starter must be disconnected from the mains if repair work is to be
carried out.
It is the responsibility of the user or the person installing the MCD 203 to
provide proper grounding and branch circuit protection according to the
National Electrical Code (NEC®) and local safety codes.
Local regulations may require a line contactor to be installed, to ensure that the starter is completely disconnected from mains voltage in the event of a trip.
Warning Against Unintended Start
-
The motor can be brought to a stop by means of digital or bus commands while the soft starter is connected to the mains.
If personal safety considerations make it necessary to ensure that no unintended start occurs, these stop functions are not sufficient. -
A motor that has been stopped may start if faults occur in the electronics of the soft starter, or a temporary fault in the supply mains or the motor connection ceases.
Avoiding Soft Starter Damage
- Do not connect power factor correction capacitors to the soft starter output. Static power factor correction, if used, must be connected on the mains side of the soft starter.
- Do not apply incorrect voltages to the MCD 203 control inputs.
Electrostatic Precaution: Electrostatic discharge (ESD)
Many electronic components are sensitive to static electricity. Voltages so
low that they cannot be felt, seen or heard, can reduce the life, affect
performance, or completely destroy sensitive electronic components. When
performing service, proper ESD equipment should be used to prevent possible
damage from occurring.
Disposal Instructions
**** Equipment containing electrical components may not be disposed together
with domestic waste.
It must be collected separately as electrical and electronic waste according
to local and currently valid legislation.
