1. Display Units
(DU:) - This setting determines whether the Programmer
displays currents as Milliamps through the MNPR™ or as Amps through the
network protector bus. This setting does not affect the operation of the
MNPR™, and is determined entirely by the preference of the user.
2. Network Voltage
(NV:) - This variable sets a three-phase average network
voltage below which, the network protector will not close. This value is
usually set to 60 volts. This feature prevents the network protector from
closing when there is a severe, low impedance fault on the network. If the
MNPR™ sees an average network voltage below this setting, the MNPR™
will scroll
“Network Voltage Too Low to Close”
.
3. Voltage Constant
(VC:) - This feature allows the user to set the MNPR™ to
ignore the actual voltage on the network side and operate as if a constant
voltage of 125-volts was applied to the network side.
4. Odometer Reset
(OD:) - Pressing
ENTER
at this point will reset the MNPR™
cycle counter. The Programmer will ask you to
“Press Enter to Confirm”
that
you want to reset the cycle counter. Upon pressing
ENTER
, the programmer
will proceed to the next variable.
5. Relay Fault
(FLT:) - This feature allows the user to choose what action the
MNPR™ will take if it malfunctions. When the MNPR™ identifies an internal
error it can either hold its current status or issue and immediate open
command.
6. Actual Mode
(ACT:) - This security feature allows the user to prevent the
manual alteration of the settings of a MNPR™. If this variable is changed to
off, the Relay Actual feature will not operate. The user will only be able to
choose from the preset buttons on the top row of the Programmer.
7. Download Mode
(DWN:) - This security feature only matters when Actual
Mode is on. It will program the MNPR™ as soon as one of the Relay Actual
settings is incremented or decremented without the Enter button being
pressed.
8. ASCII Mode
(ASC:) - This feature allows the user to use ASCII protocol to
program a MNPR™. If you are interested in utilizing this feature, information
can be obtained from the factory.
9. Watt-Var
(WV:) - This variable enables the Watt-Var mode of the MNPR™.
10. Brightness
(LED:) - This variable controls the brightness of the Programmer
LED display. The brightness can range from 0-7. Zero is the brightest.
