When 



=1, the ОМ

-310 device after power-on works similarly as when the remote control is off (normal oper-

ation), but writing to the R_COMMAND command register is permitted. 

 When 



=2, ОМ

-310 will energize load only after the corresponding command via RS-232/RS-485 has been 

received. 

The R_COMMAND value is regarded by the 

ОМ

-310  operation algorithm when 



=1, 



=2. If 



=0 and the 

user sets 



=1 or 



=2, then 0 will be recorded to R_COMMAND. 

The list of possible command register settings is shown in Table 2.7 
 

 Table 2.7 

 

R_COMMAND command 
register Address=220 

Actions performed 

De-energize load. If the load is de-energized, then before a power-on command 
from the Remote Control has been received, the load will not energize. If the load is 
energized, it will be de-energized. 

Normal device operation. 
If the load was de-energized by the remote control command or by pressing  DOWN, 
UP buttons (while 



=3), or in case of a failure after which automatic restart is per-

mitted, then the load will be energized within specified automatic restart time from 
the moment of de-energizing while “1” is recorded in the R_COMMAND register.  

Early load energizing. Value “2” record will lead to load power-on until expiration of 
the automatic reset time period. After load power-on, R_COMMAND =1. 

 

 

If 



=1, then after energizing “1” value (device normal operation) will be recorded in the command register. 

If 



=2, then after energizing “0” value (load de-energized until the command to energize is received) will be 

recorded in the command register. 

In case of an emergency load shutdown by simultaneous pressing DOWN, UP buttons, (while 



=2, 



=3), 

the command register will be reset to 0. 

 

2.4.6 Load energize/de-energize via remote breaker 
ОМ

-310 operation in the remote control mode is defined by the 



 parameter. 

When 



=0, the load energize/cutoff by means of remote breaker is prohibited. 

When 



=1, 

ОМ

-310 with the open terminal of the  S1  remote breaker (fig.2.1) functions the same way as dur-

ing normal operation mode. When the remote breaker terminal is closed the load relay opens (when 



=2 besides 

the load relay, the characterizing relay will also open).  

 When 



=2, 

ОМ

-310 with the closed terminal of the  S1  remote breaker (fig.2.1) functions the same way as 

during normal device operation. When the remote breaker terminal is open the load relay opens (when 



=2 be-

sides the load relay, the characterizing relay will also open). 

 When 



 =3 and 



= 4 

ОМ

-310 functions the same way as 



 =1 and 



= 2 accordingly, but AR after the 

remote motor de-energizing is forbidden. 

 

2.4.7 Fault conditions system 

In case of fault condition occurrence, the 

ОМ

-310 performs following actions: 

-mnemonic indicator displays error code according to Table 2.8; 
-value indicator displays value of the faulty parameter (if given fault does not have numeric value, the indicator 

displays “

----

“); 

-red LED FAULT lights (glows continuously if AR will not initiate, and flickers if AR is expected); 
- load relay opens; 

-

  characterizing relay closes (when 



=0). 

If 

ОМ

-310  defines several types of faults simultaneously, the error codes and parameter values are displayed 

consecutively, one after one. 

If AR is permitted, the fault codes and time left till AR are displayed. 
 

2.4.8  Faulty conditions log 

When load relay in case of fault opens, the 

ОМ

-310  device stores the fault code, the parameter value, and time 

of occurrence. 

Note. Time of fault is defined by OM internal clock. As 

ОМ

-310 has no integral power source, the time when the 

device was de-energized, is not accounted.      

Number of synchronously stored fault codes is five. When next following faults occur, the information of this fault 

is recorded over the latest fault. 

To view log press RES/MEM/SEL button.
