3.2. The device use
3.2.1.
Operating condition
The device can be in one of the following conditions:
−
" Normal o
peration
";
−
"
P
arameter
s
etting ";
− “
Fault
”.
The device is in the " Normal operation " condition if:
−
the controlled parameter does not exceed the value set by the user;
−
AR time countdown has been completed.
The parameter values are changed (Table 4) in the " Parameter settings " condition.
In the " Fault " condition: at the time of the fault, the device opens contacts 1 to 3 (the On LED is off, the
Off LED lights up continuously).
3.2.2. The device operation
3.2.2.1. Power and current control
If the value of the controlled parameter is exceeded (menu item
“
 ”, Table 4), the off-delay time
countdown begins (parameter “  ”, Table 4). At the same time, the LED
Off (it. 7, Fig. 1) and LED On (it. 6,
Fig. 1) are flashing alternately.
After completion of the off-delay time countdown (if the controlled parameter has not accepted value up to
this moment):
–
Contacts 1
– 3 are opened;
–
LED On goes out;
–
LED Off goes out;
–
The display shows the AR time in minutes and one of the LEDs blinks (it. 9-13, Fig. 1), corresponding
to the parameter, over which the protection has tripped.
If the AR countdown relative to power or current is inhibited (parameter “

”, value “  ”, Table 4), the
device does not turn on the load, the display will show “  ”.To turn on the load, you should turn off the OM-
163 power and turn it on again, or set the AR time (parameter
“

”, Table 4) as 580 min or less.
Note: when sel
ecting the controlled parameter (menu item “  ”, Table 4) the other parameters of this item are not
controlled.
3.2.2.2. Voltage control
If the mains voltage exceeds the thresholds set by the user (parameter
“  ” or “  ”, Table 4), the load
off-delay time countdown begins (fixed off-delay, Table 2). At the same time, the LED Off (it. 7, Fig. 1) and
LED On (it. 6, Fig. 1) are flashing alternately. After completion of the off-delay time countdown (if the voltage
has not accepted value up to this moment):
–
Contacts 1
– 3 are opened;
–
LED On goes out;
–
the display alternately shows the voltage AR time in seconds and the actual value of the mains voltage,
the LED Off lights up continuously (it. 7, Fig. 1). At the same time, when the AR time relative to voltage is
displayed, the dot in the low-order display is on and the indicator (it. 13, Fig. 1) does not light, and when the
voltage value is displayed, the indicator (it. 13, Fig. 1) lights up.
After the AR time countdown relative to voltage is over, the contacts 1 - 3 are closed, if the mains voltage
value is acceptable (the LED
On lights up, the LED Off goes off).
