Operating the device
Technical data
Indications
The configuration of the OM-630 relay is implemented through
four stepping potentiometers located on the front panel of the
relay:
T - Shutdown delay
OFF
If the power consumption is greater than the maximum value for
the time specified with T parameter then the K1 relay will be
OFF
switched off and the relays will be disconnected.
You can select one of the following values: 2 s – 10 s – 30 s – 1 min –
3 min – 5 min – 10 min – 30 min – 60 min.
T - Time interval
ON
Time for which the K1 relay and the receivers will be switched off
in case of exceeding the preset power level.
You can select one of the following values: 1 s - 2 s - 10 s - 20 s - 60 s
- 90 s - 120 s - 180 s - 240 s.
P - Power (rough)
Defining a preset level of power limit.
Potentiometer P allows you to roughly select one of the power
ZG
sections in the range of 5 to 50 kW.
∆P - Power (precise)
Potentiometer PDOK allows you to precisely adjust the power in
the range of 0 to 4.5 kW
.
The indication of the power limiter operating state is imple
-
mented through four LEDs:
U - power supply
R - relay

<U>- voltage out of range
