6. CONNECTION
OVP-15P voltage relay is connected to a standard socket of 230 V / 50 Hz
power supply network. The socket must be rated at the current 16 А.
Protected devices are connected to the output socket of OVP-15P.
The voltage relay is designed for operation indoor only. The device
operation is inadmissible in places with high humidity and where ingress of
liquid on its case is possible. Ambient temperature during the voltage relay
operation must be in the range +10 to +35 °С.
7. OPERATION
The voltage relay has the following operation modes:
•
normal operation;
•
protection mode;
•
turn-on delay mode.
The voltage relay is in normal operation, when the active voltage of the power
supply network is within 199–252 V limit and the turn-on delay time is over.
In this mode the protected equipment connected to the relay is
de-energized, the indicator
b
lights continuously.
If the voltage exceeds the set thresholds, the relay enters the protection
mode. In this mode the equipment connected to the relay is de-energized
and one of protection indicators starts to light:
c
when high voltage
protection is
actuated or
a
when low voltage protection is actuated. The
voltage relay will be in this mode as long as the supply voltage attains a value
within 204–244
V
± 2% range.
The relay enters the turn-on delay mode after its connection to the power
supply network or when it leaves the protection mode. In this mode the
equipment connected to the relay remains de-energized till the end of delay
time, and the indicator
b
blinks during this time. The turn-on delay value
for
OVP-15P voltage relay is180 sec.
Force transition from the turn-on delay mode to the operation mode can be
done by pressing the button
