6 Use

6.1 Before energizing the relay, confirm whether the voltage level of the connected relay is consistent with the actual parameters, otherwise the relay may be damaged; check whether the relay is damaged during transportation and storage, and the relay screw fasteners should not be loose; if there are damaged parts , Please contact us to replace it for you.

6.2 RZH-11/21, RZH-11/25, RZH-11/26, RZH-12, RZH-21/21 relays will open instantaneously, and the relays will be closed after a delay action. RZH-11/22, RZH-11/23, RZH-11/24, RZH-13, RZH-23, RZH-21/22, RZH-21/23 Relay When the power monitoring circuit monitors the power circuit control power supply loss , After the power-off delay action alarm, at this time the closing circuit also returns instantaneously due to the disappearance of the power supply; if the power supply is normal, the closing circuit will act instantaneously and the power-off delay will return; the opening monitoring circuit will act instantaneously.

6.3 The delay of the power monitoring and closing circuit is set with the dial switch according to the formula on the relay panel.

The power monitoring delay time setting range is 0.5-5S, t=[0.5×□+0.5 ]S
