MPS3000 TERMINALS

        

 

Page 15 of 67 

MPS3000-C special use: 
The relays can be configured with contactors control functions which may be required, according to the control 
application. 
 

Output A Relay:

 

Can be configured as one of: 
* DOL starting  
* Star period of Star-Delta starting 
* Forward of a forward-reverse motor  
* High speed of two-speed motor   
 

Output B Relay:

 

Can be configured (by parameter setting) as one of the following functions: 
* Delta period of Star/Delta starting 
* Reverse of a forward-reverse motor 
* Low speed of two-speed motor   
 

Output C Relay:

 

Can be configured (by parameter setting) as one of  the following functions: 
* Contactor A status. 
* Contactor B status.  
* Start/Run - controls line contactor in Star-Delta starters. 
 

Serial Link 

Standard  RS485  Half  Duplex, with MODBUS protocol.  
Twisted shielded pair should be used for wiring

. 

Shield should be connected to Chassis Ground externally, 

near the MPS3000. 
Acceptable baud rates: 1200, 2400, 4800, 9600 and 19200 BPS. 

Serial Port (+)  

.........................................

23 

Serial Port (-) 

 ......................................... 

22 

Serial Port (shield) 

.................................

 63 

Notes:

  

1.  Auxiliary Power Supply must power-cycled after changing communication's settings (e.g. baud-

rate). 

2.  Connect 120 Ohm resistors between (+) and (-) at the end and at the beginning of the line.
