Sven OVP-15P [18/20] Voltage relay

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 vol tage 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 d.
