Remote Keypad
EMX4 starters can be used with a remote keypad, mounted up to 3 metres away
from the starter. Each expansion card includes a keypad connection port, or a
dedicated keypad connector card is available.
Finger Guard Kit
Finger guards may be specified for personnel safety. Finger guards fit over the soft
starter terminals to prevent accidental contact with live terminals. Finger guards
provide IP20 protection when used with cable of diameter 22 mm or greater.
Finger guards are compatible with models EMX4i-0184B ~ EMX4i-0580B.
Soft Starter Management Software
PC software can provide real-time or offline management of soft starters.
•
For real-time management in a network of up to 254 starters, the
software must connect to the soft starter via a Modbus TCP or Modbus
RTU card. The software can monitor, control and program the starter
across the network.
•
The software can be used to program the starter via the USB port on the
pumping smart card.
•
For offline management, a configuration file generated in the software
can be loaded into the starter via the USB port.
3.8
Main Contactor
A main contactor is recommended to protect the soft starter from voltage
disturbances on the network, while stopped. Select a contactor with an AC3 rating
greater than or equal to the full load current rating of the connected motor.
Use the main contactor output (33, 34) to control the contactor.
WARNING
When connecting the EMX4i in inside delta configuration, always install a
main contactor or shunt trip circuit breaker.
3.9
Circuit Breaker
A shunt trip circuit breaker may be used instead of a main contactor to isolate the
motor circuit in the event of a soft starter trip. The shunt trip mechanism must be
powered from the supply side of the circuit breaker or from a separate control
supply.
