Once 

B, 4

 is pressed, the Programmer will display the current MNPR™ status 

“BLOCKED”

 or 

“AUTO”

.  Pressing 

NEXT

 will immediately tell the MNPR™ to 

switch to the other status. 

 

Note: If the MNPR™ is removed from the network protector in the Blocked 
state, it will still be Blocked from closing when re-installed. 

 

B. Open Relay

 - press 

A, 4

. This will immediately cause the MNPR™ to issue a 

Open command to the network protector.  Once the open signal is set, the 
MNPR™ will immediately return to normal operation. 

 

Note: If the user wants the MNPR™ to open the protector and not allow it to 
close, it is necessary to use the Block command (see above) before an 
Open Relay command is issued. 

 

VI. Advanced Programming 

 

This manual has discussed every button combination on the Programmer except for 

D, 4 

- the Program command.  This command does not program the MNPR™.  It 

programs the Programmer. 

 

A.  Level 1 Programming 

 

Pressing 

D, 4

 at the 

“ETI_ _”

 Scroll will cause the MNPR™ to display 

“Enter 

Program Password”

 to proceed. Because misuse of the Program command can 

result in damage to the MNPR™ and the network protector, the password is not 
distributed with the Programmer.  The password can be obtained from the 
factory. 

 

NOTE: If you pressed D, 4 and do not have the password, simply press any 
letter on the Programmer 8 times to return to the 

“ETI  _ _”

 scroll. 

 

Entering the correct password allows the user to program the preset variables for 
each of the modes present on the top row of the Programmer.  As usual, 
pressing 

NEXT

 will toggle through individual variables; 

INC

 and 

DEC

 will adjust 

each variable.  It is possible to adjust multiple variables before pressing 

ENTER

 
Setting these variables and pressing 

ENTER

 does not Program the MNPR™.  

Selecting any of the top row from the 

“ETI _ _”

 scroll will program the MNPR™ to 

those settings.  The variables appear in the following order: 

 

1. Reclose Volts

 (RV:) - This variable programs the reclose voltage for all of the 

presets located on the top row Sensitive (standard), Time Delay, Insensitive 
and Watt-Var.
