PROGRAMMING MENU
Input B trip The relay closes when Input B activates to trip the soft starter.
Motor overload The relay closes when the starter trips on Motor Overload.
Current imbalance
The relay closes when the starter trips on Current Imbalance.
Undercurrent The relay closes when the starter trips on Undercurrent.
Instantaneous overcurrent The relay closes when the starter trips on Instantaneous overcurrent.
Frequency The relay closes when the starter trips on Frequency.
Ground fault
The relay closes when the starter trips on Ground Fault.
Heatsink overtemperature
The relay closes when the starter trips on Heatsink Overtemperature.
Phase Loss The relay closes when the starter trips on Phase Loss.
Motor thermistor The relay closes when the starter trips on Motor Thermistor.
Changeover Contactor
The relay closes when the high rotor resistance current ramp has reached full
voltage, allowing use with a slip-ring motor.
Undervoltage Not available with EMX3.
Ready The relay is closed when the starter is in Ready state.
Description:
Selects the function of Relay A (normally open).
7B – Relay A On Delay
Range:
0:00 - 5:00 (minutes:seconds)
Default:
0 second
Description:
Sets the delay for closing Relay A.
7C – Relay A Off Delay
Range:
0:00 - 5:00 (minutes:seconds)
Default:
0 second
Description:
Sets the delay for re-opening Relay A.
7D~7L – Output Relays B, C, D, E, F
Parameters 7D~7L configure the operation of Relays B, C, D, E and F in the same way as parameters 7A~7C configure Relay A.
Refer to
Relay A Function for details.
Relay B is a changeover relay.
• 7D Relay B Function
Default:
Run
• 7E Relay B On Delay
• 7F Relay B Off Delay
Relay C is a changeover relay.
• 7G Relay C Function
Default:
Trip
• 7H Relay C On Delay
• 7I Relay C Off Delay
Relays D, E and F are only available if the input/output expansion card has been installed. These relays do not support on or off
delays and do not support 'Changeover Contactor' function. Relay D is normally closed, relays E and F are
normally open.
• 7J Relay D Function
Default:
Off
• 7K Relay E Function
Default:
Off
• 7L Relay F Function
Default:
Off
7M – Low Current Flag
The EMX3 has low and high current flags to give early warning of abnormal operation. The current flags can be configured to
indicate an abnormal current level during operation, between the normal operating level and the undercurrent or instantaneous
overcurrent trip levels. The flags can signal the situation to external equipment via one of the programmable outputs.
The flags clear when the current returns within the normal operating range by 10% of the programmed flag value.
Range:
1% - 100% FLC
Default:
50%
Description:
Sets the level at which the low current flag operates, as a percentage of motor full load current.
7N – High Current Flag
Range:
50% - 600% FLC
Default:
100%
Description:
Sets the level at which the high current flag operates, as a percentage of motor full load current.
